Humidifier and Humidistat Another popular option for the Wine Guardian split system is a humidifier. The humidifier is available as a freestanding unit powered by the Wine Guardian system, with its own power cord and humidistat or as an integrated unit that bolts to the side of any Wine Guardian ducted system. The Wine Guardian humidifier requires a water supply and drain for operation. Please refer to the Humidifier Manual for Installation Instructions. Duct Collar Kits Ductwork for the Wine Guardian system is sold in kits by size for each unit. Each kit contains two adapter collars, one 25-foot (7.3 meters) length of round flexible duct, and two straps. The number of duct kits needed depends on the installation layout. The size of the ductwork kit depends on the selected model of Wine Guardian system. Follow installation instructions carefully. Poorly or incorrectly installed ducts can degrade the performance of your unit dramatically. Extended Compressor Warranty The Wine Guardian uses only the best commercially available compressors on the market. However, since the compressor is the single most expensive component in the unit, it is recommended that you purchase the extended warranty option.

Component Overview Cabinet ­ The cabinet (outer housing) is constructed of aluminum with a powder-coated finish for corrosion protection.
Condensing Section ­ Ambient air is circulated through the condenser section by a direct drive, permanently lubricated, motorized impeller blower. This section also contains the compressor.
Evaporator Section ­ Cellar air is circulated through the evaporator section by another blower, similar to the condensing section. The large evaporator- coil face area eliminates condensate carry-over, reduces air pressure drop and optimizes heat transfer. A drain pan is located directly below the coil to capture condensate and is fabricated from aluminum to prevent rust and corrosion. The electric heating coil, if ordered, is factory installed between the evaporator coil and the blower and is complete with contactors and limit controls.
Electrical Controls ­ Most of the electrical components and controls are in a separate area accessible on the side of the unit. All wiring is in accordance with the NEC. Wires are numbered and color coded to match the wiring diagrams.
Internal Drain Trap – Water condensate from the evaporator coil fills the trap and forms a seal to prevent air from being drawn back through the drain tube. This allows the drain pan to drain freely. No external trap is required.
Supply/Return Duct Collar ­ A composite-material, single-direction duct collar is provided for both the inlet and outlet of the evaporator section. Two duct collars are provided with the unit; every duct collar is interchangeable with access doors to control and direct the airflow. These duct collars can be removed via the two quarter-turn screws.
Refrigerant Circuit ­ The factory charged circuit includes a thermal expansion valve with an external equalizer, sight glass with moisture indicator, a filter dryer, an automatic low-pressure switch, and a manual reset high- pressure switch. For the Extreme Climate Protection option, an automatic pressure switch controls the operation of the condenser blower, and a heating element is added to the compressor oil reservoir.
Removable Panels ­ Insulated composite-material removable panels are provided on the evaporator of the unit. These panels can be removed via the two quarter-turn screws.

Installation

For questions or help regarding installation, call customer service at 1-315-452-7400 or email info@wineguardian.com a sketch of the proposed area where the unit is to be installed. Pre-Installation Test the system before installing it to check for non-visible shipping damage.
Set the system on the floor or on a sturdy, level surface. Ensure the control cable and remote interface controller are plugged into one of
the com ports. Plug in the system. Press the on/off switch to see if the control illuminates. This indicates the system
has power.
RISK OF PERSONAL INJURY OR DAMAGE TO EQUIPMENT SHARP EDGES ARE PRESENT INSIDE THE WINE GUARDIAN SYSTEM Pre-Installation Planning
IMPORTANT Installation of residential and commercial split systems must be performed by qualified service technicians with proper training in the installation, start up, service, and repair of these systems.
Certification to handle refrigerants is also required.
Prior to installation, determine how best to mount the system. Installing The Fan-Coil Floor Mounting – Mount the Wine Guardian fan coil on the floor but elevate it 4″ (10cm) as a minimum on a frame with a plywood surface to keep it away from water. Allow adequate space for the external drain.
26

Wall Mounting – If the Evaporator is to be surface mounted on the wall, adequately support it on both sides of the wall. Use floor or knee braces to transfer the load of the unit to the floor or wall. Ceiling Mounting – Construct a structurally sound, level platform to place the Evaporator on when hanging it from the ceiling joists. The Wine Guardian fan coil is NOT designed to be suspended from the top of the unit; it must be supported from the bottom. Place the unit on a platform to ensure the unit is supported on all four corners. Leave adequate space above the unit to remove the access doors for service.
In all cases the unit must be level to within ±0.25″ (±6.35mm) end-to-end and ±1/8″ (±3.18mm) side-to-side for proper operation. Locate the unit as close to the wine cellar as possible to reduce the length of the duct runs. If possible, use straight ducting on all duct work. Reducing Noise Generation Consider noise when locating the unit close to the cellar or to an adjacent occupied space. The addition of 0.25″ (6.35mm) thick rubber pads under the unit will help prevent the transmission of vibration and noise. A piece of 1″ or 2″ (25 or 50mm) noise dampener between the unit and the wall absorbs and reduces noise from the unit. For air noise, use flexible ductwork to absorb the noise. Sound usually travels as a line of sight. Sound is reduced when it turns a corner, such as passing through a bend in ductwork. If the unit is supported from a wall or joist, using a rubber pad under the unit will reduce noise caused by vibration. Ductwork Wine Guardian units are typically installed indoors near the wine cellar to minimize duct runs. Each unit is provided with one entering (or return) air inlet and five possible supply air outlets for the evaporator sections. A maximum cumulative total length for both supply and return ducts (including bends) of 25 ft (7.5 meter) is recommended. If longer runs are needed, examine your duct runs using our Ductwork Calculator.
27

Use ductwork to connect the unit to the supply and return outlets in the wine cellar. Use only insulated ductwork to minimize cooling losses, to prevent sweating, and to reduce noise.

Use ductwork on the condenser section to redirect or absorb sound, to bring in outside air to the unit inlet, and/or to exhaust the hot air out of the ambient space.

It is best to oversize ductwork if exact ductwork diameters are not readily available or easily accessible

Note: The above referenced sizes are internal diameter in inches for 60Hz and in millimeters for 50Hz. If a single supply duct is used but then splits into two ducts, the duct size that is recommended for double duct runs is used after the split occurs (ex. 8″ duct would split into two 6″ ducts).

Cold Air to/from Wine Cellar Connect the supply-air ductwork from the cellar to the supply-air duct collar at the
Wine Guardian unit. Connect the return-air ductwork from the cellar to the return-air duct collar at the
Wine Guardian unit.
Warm Air to/from Condenser Connect the supply-air ductwork from the condenser to direct heat and air noise
away from occupants. Connect the supply-air ductwork from the condenser either outdoors or to a
space that is 3x larger than the wine room if the heat being exhausted is
undesirable.

Drain Line Splice the drain line onto the drain outlet with a short piece of ½” copper tubing and secure the drain line to the unit with a hose clamp. The drain line’s interior diameter should be ½” (12.7mm). The drain line must extend from the unit to an open floor drain or condensate pump. Do NOT install an external trap on the drain line, every ducted Wine Guardian unit is built with an internal trap. Allow enough height for the drain line to function properly. If draining into a nearby sink, the unit must be elevated higher than the rim of the sink in order for the water to drain by gravity. Install with a ¼” (6.35mm) per linear foot of pitch. Do not tie the condensate drain line directly into the sanitary sewer system. The internal drain trap primes itself automatically once the unit has run for a period of time and after the unit cycles off. This is confirmed by water dripping from the drain. Wiring the Fan-Coil Match the Electrical Wiring to the cord provided on the Wine Guardian fan coil. Provide dedicated circuit and wiring for the system. Match the wiring and breaker size to the rated load as shown on the serial plate and in this guide. Please see the sample serial plate illustration.
ELECTRICAL SHOCK HAZARD RISK OF SERIOUS INJURY OR DEATH The electrical outlet and wiring installation must
meet the national and local building codes.
30

Do NOT modify the plugs in any way. Do NOT use extension cords.

Depending on the model, the electrical power supply must be either 115-volt or 230-volt AC, 1 phase, 60 cycle, and the electrical power cannot vary more than ±4% or damage may occur to the unit.

Plug the unit into the wall outlet, gently pull on the plug to make sure it is tight.

Installing The Condensing Unit
· Condensing units are factory assembled with an anodized aluminum outdoor
enclosure for protection from the elements.
· A minimum of 12″ (30cm) is required around the perimeter of the condensing unit for
proper airflow across the coil and to provide an adequate discharge airflow path. Any obstructions to this airflow will result in a decrease in performance and possibly premature failure due to a buildup of high pressure within the system.
· The condensing unit is designed to operate in ambient temperatures ranging from
20°F-115°F (minus -7°C – 46°C), as it is supplied with many standard features to assist full operation in this wide range.
· Mount the condensing unit above normal snowfall levels to allow uninhibited winter
operation. A buildup of snow or any other obstruction to airflow will result in a decrease in performance and possible premature failure due to increasingly high pressure within the system.
Installation of Interconnecting Refrigerant Lines Note: The interconnecting copper refrigerant lines shall be supplied by the installer. The larger suction line must be fully insulated along its complete length from condensing unit to fan coil unit. There is a factory-installed liquid line filter-drier inside the condensing unit; therefore, no additional drier is needed for proper operation. A liquid line moisture/sight glass is factory installed in the condensing unit to assist in monitoring the refrigerant charge and the state of the refrigerant in the system.
· Keep horizontal and vertical distances between the indoor and outdoor section as close as possible to minimize refrigerant charge required. This will reduce system issues related to oil management that can impair performance and jeopardize the compressor’s lubrication.
· Provide a ½” (12.7mm) pitch in suction and liquid line toward the condensing unit for every 10 ft (3 meters) of run to prevent any refrigerant that condenses in the suction line from flowing to the compressor when the unit is off. These two lines can be routed together and wrapped together, as long as the suction line is fully insulated, as previously directed.
· Suction line riser traps are not required if the riser is properly sized to maintain refrigerant velocity. Adding a trap will only increase pressure drop.
· Prevent dips, sags, or other low spots that will trap refrigerant oil, which is an issue especially with long horizontal runs. Use hard refrigerant copper for longer horizontal runs to prevent potential oil return problems. (See sample piping chart on page 34)
· When sweat connections are made in the connecting lines, be sure that the inside of the tubing is clean before installing the unit. Use a dry nitrogen bleed during brazing. Note: that compressor suction and discharge valves should be open to the atmosphere no longer than 15 minutes. Compressors with POE (polyolester) oil will quickly become contaminated when opened to atmosphere.

Sample line Set Configurations
Leak Checking and Evacuation Process · Pressurize and leak test the interconnecting lines, including the fan coil unit, fittings,
and brazed joints using the intended operating refrigerant, nitrogen, or dry air for leak testing. A pressure equal to the low-side test pressure marked on the unit nameplate is recommended for leak testing. Repair any leaks found. Connect a good vacuum pump to both the low- and high-side service valves while still in their factory supplied position, isolating the refrigerant charge in the condensing unit. Draw a deep vacuum of at least 15pp microns. Do not use the motor compressor to pull a vacuum and do not operate the motor compressor in a vacuum. · Evacuate the system to hold at 500 microns and break the vacuum by releasing the factory refrigerant charge in the condensing unit to interconnect lines and fan coil unit by opening service valves. Remove the vacuum pump. The system is now ready for
34

optimal charging. Refer to page 57 of this manual for correct refrigerant charging based on your interconnect length. Charge the system with the correct amount of refrigerant and mark the amount with a ballpoint pen in the space provided on the unit nameplate.
Note: When charging through the suction service valve the refrigerant should be charged in vapor form. NEVER CHARGE IN LIQUID FORM. Refrigerant should always be charged through a dryer. Charging in liquid form may damage the valve plate assembly as well as scrub the oil out of the compressor bearings.
Be sure there is not an overcharge of refrigerant. An overcharge might permit liquid refrigerant to enter the motor compressor and damage the valves, rods, pistons, etc.
Wiring the Condenser
· Wire the system as per the supplied wiring schematics starting on page 17 of this
manual OR on the door of the condenser.
· The DS fan coil unit is powered through a factory-supplied power cord (for DS models,
WGS is hard connected), but you will need to run 24-volt power wires from the lowvoltage terminal block on the fan coil to the terminal block in the junction box in the condensing unit labeled Y & C. This can be typical controller wire or 18- gauge insulated wire. (See images below)

· The condensing unit needs to be hardwired. To bring the rated high voltage to the
factory-installed contactor in the chassis cabinet to line side (L1 & L3) of the contactor. Use table 1 to identify the minimum recommended AWG, USE COPPER WIRE ONLY. Run a ground lead to be connected to the condensing unit Ground lead/LUG. There is a separate ground lug for the condensing unit internal components (See Fig 3). The load side of the factory-installed contactor will be factory-wired.
· Turn on power to the condensing unit 24 hours prior to system start-up to allow
crankcase heater to warm up compressor crankcase.

Installing the Remote Interface and Communication Cable

one of two ways:

The Wine Guardian Wireless-to-base Remote Interface Controller is a combination temperature and humidity controller with single stage cooling, heating, and humidity control. Its capacitive touch screen incorporates an on/off switch, adjustment arrows and settings buttons for ease of use and programming. The controller can be installed

IMPORTANT

Whenever possible we strongly suggest wiring the Remote Interface Controller directly to the Wine Guardian unit to avoid periodic battery changes and uninterrupted service.

Wired (recommended) ­ wired directly to the Wine Guardian unit through an RJ-9 communication cable. 50′ (15.25 m) of control cable is included with each controller with longer lengths available as an option.
IMPORTANT
Wireless installation may result in limited communication range and connectivity issues depending upon building construction and distance between Wine Guardian
unit and Remote Interface Controller and/or Remote Sensors. Wirelessly – connects wirelessly to the Wine Guardian unit by Radio Frequency connectivity through one of twelve selectable channels.
The Wine Guardian Wireless2Base Remote Interface Controller is a configurable device that can be fine-tuned through a series of individual settings. The controller incorporates eight (8) key temperature, humidity, and system alarm points. Remote alarm indication is possible through terminal point connections at our main control board.
In most applications, the remote interface controller will be mounted within the wine cellar. The remote interface controller can also be mounted directly outside the wine cellar or in any other room of the home or building. When mounted outside the wine cellar, a remote sensor kit or a second wireless remote interface must be purchased and installed within the wine cellar.
IMPORTANT
Regardless of wired or wireless connection, each Wine Guardian System can have a maximum of two (2) Remote Interface Controllers and three (3) Remote Sensors.

~WARNING~
Air movement though an unsealed opening in the wall will cause condensation damage to the controller. Use durable tape to seal the opening in the wall after applying insulation around the wire in the opening.
37

Additional Remote Interface Prior to adding an additional remote interface to the system, you will have to change setting 30 on the first controller to give it a different address. Refer to page 45 for instructions on how to access the interface settings and get to Setting 30 (shown on page 50).

Mounting the Remote Interface Controller (Wired)

1. Remove the comm cable from the zip lock bag and attach it to the side of the Wine Guardian unit (Fig. 1). a. Route the communication cable within the wall and/or ceiling structure of the wine cellar to the desired controller mounting location.

Fig.1

b. Plan on mounting the remote interface controller on a solid surface away from doors, corners, air outlets, drafts or heat generating equipment. Do not mount the remote interface controller directly on an outside wall, a wall adjacent to a boiler room, or other hot area. Use a piece of foam insulation behind the sensor to insulate it from a hot or cold surface. The recommended height 5ft to 6ft (1.5m to 1.8m) above the finished floor.

Fig. 3

2. Locate the Mounting Template upon the wall where the Controller will be mounted (Fig. 2). Using the crosses on the template to assist in levelling the template.
3. Drill two 1/8″ holes and insert anchors at the marked locations. Anchors may not be required if securing to a wall stud or racking system. Insert the screws into the holes and test fit the backing plate to ensure it mounts easily onto the two screws and slides down onto the slotted opening freely (Fig. 3).
4. Plug in the communication cable to the back of the remote interface controller backing plate. a. If using multiple Remote Interfaces either connect each Sensor to each other in series using RJ9 cable or purchase a RJ9 Splitter to be used on the unit.
5. Attach the Controller to the wall (Fig. 4).

Installation of the Wine Guardian Remote Sensor The wireless remote sensor is a combination temperature and humidity sensor only. It is designed to be mounted within the wine cellar and can be used in combination with the remote interface controller or up to two additional remote sensors to read and control multiple areas within the wine cellar.
For a wired application you will require a RJ-9 communication cable.
Mounting the Remote Sensor (Wired)

Fig. 1 Fig. 2

1. Disconnect the communication cable from the side of the Wine Guardian unit and the remote sensor. Route the communication cable within the wall and/or ceiling structure of the wine cellar to the desired controller mounting location.
2. Plan on mounting the remote sensor on a solid surface away from doors, corners, air outlets, drafts or heat generating equipment. Do not mount the remote sensor directly on an outside wall, a wall adjacent to a boiler room, or other hot area. Use a piece of foam insulation behind the sensor to insulate it from a hot or cold surface. The recommended height is 5ft to 6ft (1.5m to 1.8m) above the finished floor.
3. Remove the remote sensor’s face plate (Fig. 1) and mark the mounting points at the desired location within the wine cellar (Fig. 2). Also, mark the location of the communication cable connection as this area will require sufficient clearance, for the cable to exit the wall and attach to the back of the sensor.
4. Drill two 1/8″ holes and insert anchors within the mounting surface. Anchors may not be required if securing to a wall stud or racking system. Insert the screws into the holes and test fit the backing plate for mounting to ensure it mounts easily onto the two screws and slides down onto the slotted openings freely. (Fig. 3)

Fig. 4 Fig. 5

5. Plug in the communication cable to the remote sensor and mount the Remote Sensor to the wall. (Fig. 3)
6. Reattach the sensor’s faceplate (Fig. 4) 7. If multiple sensors are being used either connect each Sensor
to each other in series using RJ9 cable or purchase a RJ9 Splitter (Fig. 5) to be connected to the unit.
Note: Remote Sensor’s will always be treated as “enabled” when hardwired. Their temperature and humidity readings will always be calculated towards the average by the system.
Note: if the Remote Interface Controller will be located outside the wine room, then change setting 30 to either 3 or 4 to disable its sensors. This will help reduce the possibility of incorrect readings.

Remote Sensor Pairing ­ Multiple Sensors (Wireless)
If using multiple remote temperature/humidity sensors in your application, refer to the figures and the procedure below to change each remote sensor’s device number (Three Remote Sensors maximum). Each Remote Sensor must have its own device number and must also be on the same RF channel (Setting 31) as the system they are being paired with.
1. To change the remote sensor’s device number, see the following instructions:

Fig. 1

a. Use a pin to press the button for about half a second and release (Fig. 1).
b. Observe the LED on the side of the remote sensor (Fig. 2&3). The LED will flash once for a Device #1, twice for a #2, three times for a #3. At any time, while in this mode press the button once to change the device number. Once each remote sensor has its own unique device number simply wait for the LED to stop flashing and the setting will be saved.

2. To change the remote sensor’s RF channel, see the following instructions:

Fig. 2

Note: Check what RF Channel the System is set to using Setting 31 to connect your Remote Sensors more easily.

Fig. 3

a. Use a pin to press the red button at the back of the Remote Sensor for 5 seconds until the LED blinks rapidly then release the button.
b. The LED will flash several times to portray which RF channel it is set to and repeat a total of 3 times.
c. To change the RF channel, press the button once to increment the RF channel. There are 12 possible RF channels. All Remote Sensors will need to be on the same channel for the system to detect them. To save the RF channel setting simply wait for the mode to time out by not pressing the button.

Start-Up

Prior to charging the system and start-up ensure the system has been powered for at least 24 hours. This is required so the compressor’s crankcase heater has ample time to warm the system to avoid premature failure. Then proceed to charging the system.
Refrigerant Charging Note: Models DS, and WGS utilize a Headmaster control valve to control head pressure at low ambient applications, therefore require a specific initial charging procedure as outlined below.
Determining the amount of charge (Low Ambient and Extreme Climate Protection) When “refrigerant side” head pressure control is utilized on a system, one of the most important factors is determining the total system refrigerant charge. While on most packaged units the amount of charge is listed on the unit, the required charge for a field built-up system cannot be listed by the manufacturer. Charge is usually added when the system is started up until “proper” system performance is reached. However, this is not satisfactory and if the system is to function properly year-round, the correct amount of extra charge must be calculated ahead of time.
Charging System with Head Pressure Control Note: When charging any system with head pressure control the outdoor ambient temperature must be known.
Charging of Systems with Head Pressure Control in temperatures above 70°F (21°C) (After normal evacuation procedures):
1. Connect refrigerant cylinder to liquid line service valve port. 2. Charge liquid refrigerant into the high side of the system. Weighing the charge is
recommended. 3. Remove the refrigerant drum and connect it to the suction service valve. 4. Charge refrigerant vapor into the low side. Do not allow liquid refrigerant into the
low side. 5. Start the system. 6. Observe sight glass (factory-installed) to see if system is filling with refrigerant for
normal refrigeration cycle. 7. If the Sight glass shows bubbles, more refrigerant may be required, while
allowing sufficient time for the refrigerant to stabilize and clear the Sight glass. Use supplied information on the following pages for proper final charge.
BUBBLES IN THE SIGHT GLASS CAN BE CAUSED BY FLASHING DUE TO PRESSURE DROP FROM PIPE OR ACCESSORY LOSSES, ETC.
54

Charging of Systems with Head Pressure Control in temperatures below 70°F (21°C) (After normal evacuation procedures):
1. You must power the condensing unit for up to 24hrs prior to charging the system to allow the system to energize. This will allow the compressor’s oil crankcase to warm. If not done hours in advance of the system/compressor start-up, there is risk of premature compressor failure, which would not be covered under warranty.
2. Follow instructions 1 through 7 above. 3. If the valve setting is correct for the system being charged, it is quite likely some
refrigerant will be backed up into the condenser and the Sight glass will indicate bubbles in the liquid line. 4. Add more refrigerant, while allowing sufficient time for the refrigerant to stabilize and clear the Sight glass. Use supplied information on the following pages for proper final charge. 5. At this point the system is correctly charged for this type of head pressure control at the ambient temperature that exists while the charging procedure is taking place. 6. If the system is designed to operate at ambient below the ambient that exits during charging, additional charge may have to be added now.
Good system performance during low ambient operation depends on proper refrigerant charge; therefore, it is very important that this phase of the installation procedure be done carefully. Poor system performance is often caused by over- or under-charging of refrigerant and may be the most overlooked.
With the system started
· After following instructions on the previous page Charging for Systems with Head
Pressure Control, with refrigerant tank now connected to suction line (low side) port to add remaining charge in a gas state, refer to the provided charts for proper system operating points as equated to ambient temperature with wine cellar at normal conditions of 57°F (13°C) / 55%RH. Refer to Split Systems Operations chart on page 58 for system pressures, subcooling, and superheat values to allow you to charge your system correctly.
· In addition to using the Systems Operations Chart, there is a liquid line moisture/sight
glass located in the condensing (outdoor) unit as a useful guide to help determine if the system has been sufficiently charged. HOWEVER, a full sight glass or a glass with bubbles does not necessarily indicate the system is properly charged or undercharged. There may be other factors affecting sight glass, so do not charge by sight glass method only. A full sight glass matched with proper system pressures, subcooling, and superheat values is the proper method for confirming that the system charge is correct for your application.
55

If you are not sure how to measure superheat or sub-cooling: Superheat
· Get an accurate suction line temperature on the suction line as close to the compressor inlet as possible. At the same time, attach a compound pressure gauge set to the system to read the low-side suction pressure at the suction service valve port (back seated valve stem to allow unrestricted refrigerant flow from evaporator back to the compressor). Convert suction pressure to a saturated temperature as derived from a pressure/temperature chart. Since the suction line temperature is the higher value, subtract the saturated temperature from it to derive your superheat. If your wine cellar is already at specified conditions e.g., 57°F (13°C), 55% RH) and if your superheat is very low, or zero, you may have overcharged your system.
Sub-Cooling
· With your compound pressure gauge set installed with the high-side connect to the valve port on the liquid receiver (back seated valve stem to allow unrestricted refrigerant flow from condenser to evaporator). Convert this liquid pressure to a saturated temperature from pressure/temperature chart. Next, obtain your liquid-line temperature by getting an accurate reading on the liquid line BEFORE the TXV expansion on the indoor side. Obtain this temperature entering the evaporator unit. Subtract the liquid line temperature from the saturated liquid temperature to derive the system sub-cooling.

Final Start-up Once the system has been adequately charged, disconnect power, double check the electrical and the ductwork, finally reconnect power and start the unit.
· Once the impeller is running, check the ducts and ductwork connections for any air leaks.
· Balance Air Distribution. · Confirm condenser airflow is unrestricted. · Check for excessive noise or vibration.
Once the system is confirmed to be running, introduce an independent thermostat into the wine room near the return grille and compare it to the readings of the remote interface and ensure the interface is reading correctly. If the interface requires calibration see page 48 for Setting 13.

59

During the initial start-up, the unit may run continuously for several hours, up to a day or more, while it lowers the cellar temperature. Once the unit reaches the set point temperature, it shuts off and starts to cycle on and off as it continues to lower the bottle temperature to the set point. The cellar air reaches the set point before the bottles. If the cellar temperature started at 75 °F (24 °C), the supply air temperature discharged from the unit will probably be 15 °F to 20 °F (-4 to -7 °C) colder. As the cellar temperature decreases to 55 °F (13 °C), the supply temperature differential decreases 8 to 12 °F (4.4 to 6.7°C) colder. To decrease the run-time of the unit it is recommended to use a step down process. For example, if you are aiming to hit a 55 degrees F setpoint then you would set an initial set point of 63 degrees F. Once the system has reached 63 degrees F change the set point to 60 degrees F, then 55 degrees F. Drop the setpoint in increments, so the system has time to cycle instead of running continuously to reach the preferred set point. Please note that the Remote Interface Controller will display a “High Temperature” alarm until the wine room’s temperature falls below the set point. Please see the Alarm Codes section of the manual.

Maintenance
High Voltage Risk of Serious Injury or Death Use Lockout/Tagout Procedure before opening panels
Sharp Edges Risk of Serious Injury Sharp Edges are present on the fan wheels, housing, fins, and coils
Maintenance on Wine Guardian units requires working with high voltage and sheet metal with possible sharp edges. Only qualified personnel should perform maintenance. Some tasks require knowledge of mechanical and electrical methods. Make sure you are familiar with all hazards, general safety related procedures, and safety labels on the unit.
Standing water in drain pans promotes microbial growth (mold), which can cause unpleasant odors and serious health-related indoor air quality problems. If mold is found, remove it immediately and sanitize that portion of the unit.
The Wine Guardian system is designed for minimal maintenance. The refrigerant system is hermetically sealed and requires no maintenance. The fans are permanently lubricated and require no maintenance. Some maintenance to the unit may be required due to dust or dirt in the air stream. The condenser coil is provided with a reusable, washable air filter. The filter protects the coil from becoming coated or plugged by dust. Frequency of cleaning the filters is based on the amount of dust or dirt generated in the cellar or basement.
1. Remove the duct collar on the inlet end of the unit. (Optional) 2. Remove the filter covering the face the coil. 3. Wash it under warm water.
63

4. Shake off excess water. 5. Inspect and clean the face of the coil. Sharp edges are present on the fins and
coils. 6. Reinstall the filter. 7. Replace the duct collar.
The condensate drain system traps dust and dirt. Clean the drain system once a year.
1. Shut off the rocker switch and unplug the unit. 2. Remove the grille or duct on the evaporator inlet. 3. Remove the filter and inspect the drain pan under the coil. 4. If drain pan appears soiled, pour some hot water mixed with liquid bleach
(diluted solution) along the length of the pan to flush the dirt down the drain tube. Continue this treatment until the drain appears clean and free of dirt. 5. Reinstall filter and grille/duct collar. 6. Plug in the unit and restart. Cleaning the Humidifier (Optional)
If the unit was furnished with a humidifier, it requires periodic maintenance. Follow the instructions in the humidifier guide.
All Wine Temperatures (AWT)
The heating coil is located between the evaporator coil and blower inside the transition duct. It contains the heating element and high-temperature-limit switches. The heating coil is wired to work in conjunction with the thermostat. Since the thermostat prevents the heating and cooling circuits from being energized at the same time, no additional power wiring is needed. We do recommend using the AUTO mode on the thermostat so it can switch from heating to cooling automatically. If using either the heat only or cool only mode, the thermostat will not switch automatically.
No additional maintenance is required for the heating coil. To test the heating coil operation, set the thermostat on HEAT and set the temperature above the cellar temperature. The supply air temperature should rise above the return air temperature by an amount shown in the specifications.
Extreme Climate Protection
The purpose of the Extreme Climate Protection is to protect the compressor and refrigerant system. It has two distinct components, a crankcase heater to keep the oil in the compressor warm and to prevent slugging on system start-up and a head pressure control to cycle the condenser fan on and off automatically to maintain system head pressure.
To confirm the system is working, feel the bottom of the heater when the compressor unit has cycled off. When the unit starts, the condenser fan does not start at the same time as the compressor. The condenser fan starts after the head pressure has built up. As the unit is running the condenser fan cycles off and on while it holds the head
64

pressure within a fixed range. The amount of cycling (frequency and duration) depends on the air temperature. The colder the air, the more frequent the cycling and with a longer duration.
Maintenance Schedule
Monthly (or quarterly depending on experience with cellar)
· Check filter and drain trap ­ clean if needed. · Check for noise or vibration. · Check for short-cycling of the unit ­ a turning on and off of the compressor unit
more than eight times/hour. Yearly (in addition to monthly)
· Replace filters if worn or plugged beyond cleaning. · Check evaporator and condenser coils for dirt ­ use a vacuum with a brush
attachment to clean the coils. · Clean the condensate pan under the evaporator coil by flushing. Be careful to
keep the drains pans clear of all debris. · Inspect cabinet for corrosion or rusting ­ clean and paint. · Inspect for dirt buildup on or inside the unit. Clean unit by vacuuming or wiping it
down. · Check for loose insulation, fasteners, gaskets, or connections. · Check the wiring connections and integrity or cords. · Examine ducts for any cracks or breach. · Check fan and solenoid on humidifier. · Replace humidifier drip pad (if applicable).

Resetting the High-Pressure Switch

High-Pressure Switch Has Shut Down the Unit

Every Wine Guardian unit has a manual reset high-pressure switch in the refrigeration

system. This switch shuts the compressor and condenser down if the head pressure

in the system is too high. It is intended to protect the compressor. Restricted airflow

through the condenser is the most common reason for the pressure to become too

high. This can be caused by dust covering the filter or an obstruction blocking the

airflow in the duct or grille.

Possible Cause

Solution

Head Pressure in unit is too high because Remove the obstruction in the duct/grille

an obstruction is restricting airflow

or clean the filter. Then restart the unit

after resetting the high-pressure switch.

1. Remove the access panel, grille, or duct collar on the condenser to gain access to the High-Pressure Switch.
2. Locate the High-Pressure Switch near the compressor (Fig. 1).

66

3. Push the button until it locks into position. 4. Push the rocker switch to restart the unit.
