PREPARING THE WINE CELLAR

The performance and life of your system is contingent upon the steps you take in preparing the wine cellar. Improperly preparing your enclosure or incorrectly installing your unit may cause unit failure, leaking of condensation, and other negative side effects.

It is highly recommended that you obtain the assistance of a wine storage professional.

Wine storage professionals work with licensed contractors, refrigeration technicians, and racking companies to build well-insulated, beautiful, and protective wine cellars. Whisper KOOL has put  together some useful tips to assist in thein stallation process. Our recommendations are meant to act as a guide in the process of building a proper enclosure. Your intended location may have specific needs which we do not address.

Wall & Ceiling Framing
Build wine cellar walls using standard 2×4 or 2×6 boards and ceiling joists without violating local or state codes in your area. As a general rule, the thicker the walls and the higher the insulation value, the more consistent your cellar temperature will be.

Insulation
Insulation is REQUIRED in order to properly use Whisper KOOL products. It is vital that all walls and ceilings be insulated to keep the cellar temperature as consistent as possible during the summer and winter months. Standard fiberglass or rigid foam insulation is normally used in cellar construction; in some cases, “blown-in” insulation is used. The R-value, or quality of insulation, is determined by the rate at which heat passes through the insulation. The higher the R-value, the more resistant the insulation is to conducting heat, and the more consistent your wine cellar’s temperature will be. Using higher R-values in insulation will lower your operating costs and Whisper KOOL unit run time. (R-13 is the recommended minimum; R-19 is preferred for interior cellar walls, and R-30 for ceilings and exterior walls.)

Vapor Barrier
Water vapor creates its own pressure, separate from the ambient air pressure, and will intrude into colder/drier areas. A vapor barrier is REQUIRED in order to prevent the intrusion of water vapor and maintain the correct cellar temperature and humidity. It is recommended that 6-millimeter plastic sheeting be applied to the warm side of the cellar walls. The vapor barrier must also be applied to the outside walls and ceiling. If it is impossible to reach the outside, then the plastic must be applied from within the cellar. The most common method is to wrap the entire interior, leaving the plastic loose in the stud cavity so the insulation can be placed between each stud. All of the walls and ceiling must be wrapped in plastic for a complete vapor barrier.

In areas of high humidity, such as Southern and Gulf States, the vapor barrier will prevent infiltration of warm moist air. The moist air can cause mold to form, and standing water in drain pans promote microbial and fungal growth that cause unpleasant odors and indoor air quality problems. If mold is found, remove it immediately and sanitize that portion of the unit.

Note: High humidity significantly increases the heat load on the cooling system.

Any break in the vapor barriers (cut, nail hole, over-lapping, etc.) will cause a moisture leak and must be sealed. The electric conduit is a “duct” for vapor to travel in. The conduit should be caulked and sealed on the warm air end.

* Sizing the Unit to the Room
The specification chart will provide information on the unit’s cooling capacity. There are circumstances in which a cellar design may require a larger unit due to preexisting design restrictions. Certain building materials such as glass, stone, or concrete may seem adequate but do not offer the insulation capacity required to maintain the optimum temperature for storing wine. We recommend purchasing a unit with a larger capacity to compensate for these design limitations. Undersized cooling units can lead to premature failure and/or prevent the system from reaching the desired set temperature. As a result, they are not covered under warranty.

PREPARING THE WINE CELLAR, CONTINUED

Mounting the Unit
The unit must be mounted within 18 inches of the ceiling in order to achieve sufficient cooling. As the room cools down, the warm air will rise to the ceiling. Mounting the unit high in the room will create a consistently cool environment by capturing the warm air and replacing it with cool air. Mounting the unit low in the room will result in a temperature variation in the room due to (a) the unit’s inability to draw warm air down from the ceiling and (b) cold air settling to the floor.

Unobstructed Airflow
Unobstructed airflow to and from the unit is critical for the unit’s overall performance and lifespan. Make sure there is a minimum of three (3) feet of horizontal clearance in every direction around the unit (five feet is ideal). The air blown by the fans needs to circulate and either dissipate or absorb heat from the space. The system will operate more efficiently with a greater amount of air to exchange.

NOTE: Do not attempt to mount the unit in a wall recess or attempt to camouflage or cover the unit with any sort of aftermarket grille, accessory, etc. This can restrict airflow, prevent the unit from working properly, and void the warranty. Please feel free to call Whisper KOOL Customer Service with any questions or concerns regarding installation requirements

Door and Door Seal
An exterior-grade (1¾”) door must be installed as a cellar door. It is very important that weather stripping be attached to all four sides of the doorjamb. A bottom “sweep” or threshold is also required. The door must have a very good seal to keep the cool cellar air from escaping out of the cellar. If the cellar door does not seal properly, the unit will run continuously. In cases where glass doors are used and the room size is close to the recommended unit size, the next larger size Whisper KOOL should be used. This will compensate for the insulation loss due to the lower insulation rating of glass

Ventilation
The necessity of dissipating heat away from the unit is critical to the unit’s performance and cannot be overstated. As the unit operates and cools, a greater amount of heat is generated on the exhaust side of the unit. Adequate ventilation is required in order to dissipate heat away from the unit. If ventilation is inadequate, the exhaust will heat the area or room and adversely affect the unit’s ability to cool. In some cases, it may be advisable to install a vent fan to dissipate heat from within the exhaust area. However, you must have a fresh air inlet as well. If your unit requires ducting, please contact Whisper KOOL to obtain a specially designed ducting plenum for the unit.

Using any other ducting system will void the warranty.

NOTE: If you are unsure whether you have adequate ventilation in your install location, please contact us to assess your specific installation at [email protected] or 1 800-343-9463.

Ambient Temperature Factor
The cooling unit has the ability to cool a wine cellar efficiently to 55°F as long as the intake air does not exceed 85°F. Therefore, you want to exhaust the unit in a room which will not exceed 85°F. Without proper heat dissipation the unit will not have theca pacity to keep the wine at a desirable 55°F.

WARNING! Allowing your unit to operate in high ambient temperatures for extended periods of time will greatly decrease the life of your unit and void your warranty

PREPARING THE UNIT FOR INSTALLATION

The Whisper KOOL 2000, 3000, and 4000 unit requires a dedicated 115-volt, 15-amp circuit. The 8000 unit requires a dedicated 115-volt, 20-amp circuit The unit draws a large amount of amps during its initial startup. By designating a dedicated circuit breaker, you will guarantee the unit has enough power to run effectively. Contact an electrician for assistance with the installation of this dedicated electrical circuit.

The unit must sit upright for 24 hours prior to testing and installation. To prepare the unit for testing:

• Remove unit from box
• Place unit on tabletop
• Plug in unit to electrical outlet
• Plug in bottle probe
• Turn on to test for approximately 20–30 minutes
• Turn off after test
• Disconnect bottle probe

To prepare the unit for installation:

• Match the electrical outlet to the plug provided on the Whisper KOOL unit.
• Provide a dedicated circuit and wiring for the unit.
• Provide a weatherproof plug for units connected outside.

Power surges and spikes can damage sensitive electrical equipment. Whisper KOOL recommends plugging the unit into a surge protector or power conditioner in order to protect your system. As outlined in our terms and conditions, power surges and spikes are not covered under warranty.

We recommend that you do not use a GFI (ground fault interrupter) with this product.

Electrical Inlets
The unit is equipped with two power inlets. One is located on the right side of the unit (inside of the cellar), and the other is located on the rear of the unit (outside of the cellar). Use the selector switch located on the right side of the unit to select which power inlet you would like to use. If you would like to plug the unit into a socket outside of the cellar, set the selector switch to rear. If you would like to plug the unit into a socket inside of the cellar, set the selector switch to the front position. When placed in either position, power can only enter the unit utilizing the power inlet you’ve selected.

In case the unit should lose power, check the home/main circuit breaker. If the unit does not respond properly, refer to the Troubleshooting Guide.

PREPARING THE INSTALLATION LOCATION

Minimum Tools Needed

• Hammer
  
  

• Level
  
  

• Screwdriver
  
  

• Saw
  
  

Locate the desired installation location (no lower than 18 inches from the ceiling).
Using a stud finder, locate the studs on either side of the center point, and mark them with vertical lines.

Using a level and a pencil, mark a horizontal line on the wall between the two studs, no less than 1.5 inches and no more than 18 inches from the ceiling.

Using a ruler or measuring tape, measure 16 inches down (2000/3000/4000) or 22.75 inches down (8000)and mark another horizontal line parallel to the first one. The unit is designed to fit between two studs that are 16 inches apart on center, enabling the unit to fit in the 14.5-inch horizontal space.

Using a saw, cut along the uppermost horizontal line until your saw reaches the stud. Turn the saw around, inserting it into the cut that has just been made, and cut toward the opposite stud so that there is a clean horizontal cut between the two studs. Be  careful not to cut into the studs themselves.

Make the second horizontal cut from stud to stud on the line 16 inches below the first cut.

Once the horizontal lines have been cut, make vertical cuts using the inside edge of the studs as a guide. Once both vertical cuts have been made, there should be rectangular hole in the sheetrock. Make the same hole on the other side of the wall. Using a nail, mark all four corners of the first hole by making nail holes through the sheetrock. Connect the holes with a pencil mark and cut on the other side of the wall.

Sheetrock alone cannot support the weight of a cooling unit. Therefore, it is necessary to frame the hole that has just been cut with upper and lower supports. These supports also provide solid material for the mounting bracket screws.

Using two 2x4s at 14.5 inches in length and eight 6d nails, secure the upper and lower supports to the right and left studs, just inside the sheetrock. Make sure that the internal height remains at 16 inches (2000/3000/4000) or 22.75 inches (8000) so that the Whisper KOOL unit will fit snugly through the framed cut-out.

PREPARING THE UNIT FOR INSTALLATION

Single-Piece Mounting Bracket
The SC Series utilizes a single-piece mounting bracket. This sturdy bracket frames the installation location and secures the unit to the wall.

Applying Insulation Tape
Locate the six-foot piece of black foam tape included with the unit. Align one end of the foam tape with the upper left corner of the rear side of the mounting bracket. Stretch the tape across the rear of the bracket and cut the tape at the opposite edge. Peel off the white paper backing and attach the cut piece of foam tape to the top rear side of the mounting bracket. Follow the same procedure to place a piece of tape on the bottom edge of the mounting bracket. Place the remaining piece of foam tape on one side of the mounting bracket (spanning the distance between the pieces of tape on the top and bottom edges of the mounting bracket), then cut, remove paper backing, and secure. Do the same on the opposite side of the bracket. Discard any excess. The foam tape will create a tight seal between the bracket and the wall.

Mounting Bracket Installation
Select your desired bracket mounting location (see diagram below). This location determines the depth of the installation. For example, position #1 (SC PRO 8000) keeps most of the unit out of the cellar while position #2 (SC PRO 8000) makes the back of the unit near flush on the exterior wall. Slide the bracket onto the unit, paying special attention to the flanges for mounting to the unit. Make sure they are pointing towards the back. Use the six 1/2″ pan-head screws to fasten the bracket to the unit. Under no circumstances should you use screws longer than 1/2” in length.

NOTICE: MOUNTING POSITION #1 SHOULD BE AVOIDED. POSITION #1 IS ONLY TO BE USED FOR REPLACING EXISTING UNITS THAT REQUIRE MOUNTING IN THIS LOCATION

Wine Cellar

INSTALLING THE UNIT THROUGH THE WALL

Select Power Location
Before sliding the unit into the installation location, select either the front or the rear switch on the power panel located on the side of the unit to choose which power inlet (front or rear) will be in use.

Installing the Unit
Slide the unit from the outside wall into your wine cellar with the outer flange flush to the wall. Secure the flange to the wall through the pre- drilled holes. The screws  should penetrate the studs as well as the upper and lower supports to provide adequate support for the Whisper KOOL unit (see illustration). Seal all cracks and gaps around the Whisper KOOL unit with an airtight sealant or caulking to prevent air leakage.

Note: If you use decorative moul ding, it should be attached to the walls and never to the cooling unit itself. The moul ding itself should be removable in case the unit needs servicing.

Rear of Unit

DRAIN LINE

Condensation Drain Line Tube
All units come equipped with a drain line for additional removal of excess condensate. This is a backup system to the condensate evaporator. It is mandatory to install the drain line attachment. The condensate evaporator will heat and dissipate the excess moisture through the rear of the unit. However in extreme humidity, additional condensate will be created. Conversely the high humidity air has less capacity to absorb additional moisture through the exhaust of the unit. Thus, the drain line will prevent overflow and leaking by allowing the discharge of the additional condensate.

It is important that the drain line tube be properly connected and used to prevent leakage and other problems associated with excess condensation

Failure to use the condensation drain line tube will void the warranty on the unit.

Condensate Evaporator
The SC units come equipped with a condensate management system known as a condensate evaporator. The condensate evaporator is a heating element designed to evaporate the condensate which accumulates in the cooling system as a by- product of the refrigeration cycle. The condensate evaporator is designed to evaporate 3 oz. of water for every working hour.

NOTICE: DO NOT INTRODUCE ANY TYPE OF CLEANING AGENT, DISINFECTANT OR OTHER FOREIGN MATTER INTO THE COOLING SYSTEM

SC Drain Line Installation

1. Wrap the threads of the drain fitting in plumber’s tape and screw on the plastic elbow.
2. Attach the supplied piece of 1/2″ ID clear plastic tubing to the plastic fitting.

To prevent mold from growing, allow the drain line to hang above the water line.

WRONG: Drain line is under water.

LIQUID-MEASURING THERMOSTAT SYSTEM (BOTTLE PROBE)

Whisper KOOL cooling units come with a liquid-temperature-measuring thermostat. The self-calibrating bottle probe contains a sensor chip, which communicates back and forth with the thermostat. This results in a consistent temperature setting and accuracy. Wine should be kept at a very precise, controlled temperature and humidity. By measuring the liquid temperature rather than air, the unit will operate 75–80% of the time.

Setting up the Bottle Probe:

1. Locate an empty wine bottle.
2. Fill it 75% full with room-temperature tap water.
3. Place bottle probe securely into bottle as seen in Figure 1.
4. Place the wine bottle in your wine cellar. Ensure sensor tip is fully submerged.
5. To ensure a consistent temperature, place bottle probe approximately three (3) feet away from the air output and not in the flow of the air
   

It is recommended that the bottle be placed in a central location of your

wine cellar. Avoid pulling too much on the probe cord. It may become disconnected resulting in limited functionality of the unit.

Note: The thermostat can be set between 50-70°F.

Remember: The unit operates based on the temperature of the water. Do not be misled by thermostats reading air temperature. The air temperature in the cellar will be cooler than the liquid temperature of the wine while it is reaching the optimum balanced temperature.

SYSTEM OPERATION

Initial Start-Up
When power is applied to the unit, the control will briefly display all symbols, and the snowflake symbol will be displayed (if unit is calling for cooling). There may be a brief delay (up to 60 sec.) before the evaporator fan turns on. When the evaporator fan is activated, the fan symbol will display.

APST (Advance Product Safety Technology) is a temperature control feature for the evaporator fan that comes standard with all WhisperKOOL units. APST ensures that in the event of a cooling deficiency, the heat from the indoor fan will not raise the temperature of the wine cellar, which could otherwise have an adverse effect on the wine-aging process

Setpoint
The setpoint is preset at the factory (Whisper KOOL) to 55°F. It can be adjusted by the customer between 50°F and 70°F (in 1°F increments).

Cooling Operation
Cooling is activated once the bottle probe senses a temperature that is 1°F greater than the setpoint. The controller then energizes the compressor relay which activates the compressor. The evaporator and condenser fans operate with the compressor. The unit provides cooling until the bottle probe senses that the setpoint has been reached. At this point the compressor relay is de- energized, which stops the compressor. The evaporator and condenser fans will continue to run for one minute to reintroduce any moisture from the evaporator coil and reduce the head pressure.
Humidity Features
The Fdc parameter can be increased to allow the evaporator and condenser fans to run for a longer period of time after the compressor turns off, allowing more moisture to be reintroduced into the wine cellar.
Anti-Short Cycle
The Anti-Short Cycle ensures that the compressor will remain off for a period of three minutes after the unit has reached the setpoint to allow the pressure in the refrigeration unit to equalize prior to starting the compressor.
Anti-Frost Cycle (defrost)
When the evaporator probe senses a temperature of 26°F for five minutes, the unit will enter an Anti-Frost Cycle. This will shut down the compressor and allow the evaporator and condenser fans to run to evaporate any frost accumulation on the coil. The compressor will remain off until the evaporator coil reaches 40°F, or for a maximum of ten minutes. The unit will then return to normal operation.

If the evaporator is not above 26°F after the Anti-Frost Cycle has ended, the red error light will display in the upper right corner. The alarm “Ad3” will be recorded in the alarm folder, indicating that the Anti-Frost Cycle timed out. The unit will run for five minutes and then enter another Anti-Frost Cycle. This sequence will continue until the evaporator temperature rises above 26°F.

“Def” will be displayed during the Anti-Frost Cycle. If the cycle is less than five minutes, the controller will prevent the compressor from starting until five additional minutes have elapsed. This is to prevent short cycling of the compressor.

Holding down the UP ARROW button for approximately five seconds manually starts the Anti-Frost Cycle, but only if the evaporator is below 40°F (defrost end temperature). If the evaporator is above 40°F, the display will blink three times and continue normal operation.

Bottle Probe Failure Protection
In the event that a bottle probe should fail, the APST (Advance Product Safety Technology) will automatically transition the system to a timed cycle based on detailed laboratory testing, which will ensure that the product is kept within a safe temperature range.
Display
The bottle probe temperature is displayed by default. The bottle probe, evaporator probe, and condenser probe temperatures can all be accessed by pushing the SET button and scrolling through “Pb1” (bottle probe), “Pb2” (evaporator probe), and “Pb3” (condenser probe).
Safety Features
Once the compressor relay is de-energized the controller must wait five minutes before reenergizing the relay. This prevents the compressor from repeatedly turning off and on. If the unit is calling for cooling during this time, the compressor symbol will blink, indicating that cooling is needed but the control is waiting for the Anti-Short cycle delay

In the event of a faulty bottle probe, the compressor will cycle off for 10 minutes and on for 40 minutes. “E1” will be displayed on the screen.

If the condenser temperature reaches 125°F, the compressor will shut down. The red alarm light will be displayed in the upper corner of the display. “COH” will be displayed on the screen. The evaporator and condenser fans will continue to run until the time set by the Fdc parameter has elapsed. The unit will continue normal operation once the condenser has reached 115°F.

Evaporator coil is dirty| Clean coil with a vacuum. If coil is very dirty, use a spray bottle with a small amount of liquid dish detergent. Spray coil, let set for 5 minutes, then flush with fresh water.
Something is blocking the supply and/or return air| Remove blockage
Evaporator fan is not turning on| Call installing technician to troubleshoot
Unit has not gone through an Anti-Frost Cycle| Check for ice in the depth of the coil. Melt with blow drier until coil is warm to the touch. Soak up water with a towel.
Unit continues to ice| Observe ice formation pattern. If only part way up the coil face, unit could be low on refrigerant. If all the way up, the coil may be dirty or airflow is blocked.
Unit does not run/power up
Possible cause| Solution
Unit is not plugged in| Make sure the unit is plugged into an outlet
Power switch not on| Turn unit on by pressing the power button on the control
Line voltage is incorrect rating for unit| Check line voltage to make sure there is 110V-120V
Bottle at setpoint| Lower setpoint
Thermostat not calling for cooling| Lower setpoint
Power select switch in wrong position| See page 10 for correct switch position
Faulty thermostat or wiring| Contact us at [email protected]
Cellar temperature is too warm
Possible cause| Solution
Temperature of intake air has exceeded 85°F| Intake air temperature needs to drop below 85°F
Unit is undersized for the cellar| Order correctly sized unit
Something is blocking the supply and/or return air on evaporator or condenser side of the unit| Remove airflow obstruction
Unit is mounted too low in the cellar| Relocate unit so the distance from the ceiling and top of the unit is no more than 18 inches
One or more of the fans is not turning on| Contact us at [email protected]
Compressor is not turning on| Contact us at [email protected]
Compressor keeps cycling on overload| Make sure all fans are working and there is no airflow obstruction
Poor seal around door| Make sure there are no air gaps around the door. If door seal is damaged, replace it.
Controller set too high| Lower the setpoint
Evaporator coil is frosted or iced up| Observe ice formation pattern. If only part way up the coil face, unit could be low on refrigerant. If so, contact us at [email protected].
System runs constantly
Possible cause| Solution
Leaky door seal or poorly insulated cellar| Fix leaky door seal and insulate cellar in accordance with this manual (page 8)
Unit leaks water
Possible cause| Solution
Unit is not level| Unit should be level in wall to prevent leaking
Drain line clogged or kinked| Check drain line to make sure water can flow freely
Drain is clogged, preventing water from escaping|

1. Disconnect exterior drain line and clear it out; run provided drain line brush through the drain port and into the interior drain line.
2. Open access port and, using a flashlight, check drain line for blockage; drop a pan tab into the drip tray to prevent further blockages.

Drain line does not have a downward slope| Fix drain line so there is a downward slope from the drain port to the discharge location
Coil is iced, causing the drip tray to freeze and water to overflow| Melt ice with blow drier. Soak up water with a towel.
Unit runs but does not cool
Possible cause| Solution
Lack of air flow| Make sure fan is unobstructed and coil is clean
Compressor not running| Contact us at [email protected]
Unit undersized| Contact us at [email protected]
Compressor is overheating| Shut unit off for 1 hour to allow compressor to cool. Turn back on and check for cooler air to flow out. If compressor runs, check for and clean condenser coil as a possible cause of compressor overheating. If problem repeats, contact us at [email protected].
Evaporator fan runs but compressor does not
Possible cause| Solution
Unit is running an Anti-Frost Cycle| Check evaporator coil temperature
Compressor and/or starting components faulty| Contact us at [email protected]
Fdc parameter has been increased, allowing fans to run after the compressor turns off| Lower the Fdc parameter
Compressor may have overheated| Shut unit off for 1 hour to allow compressor to cool. Turn back on and check for cooler air to flow out. If compressor runs, check for and clean condenser coil as a possible cause of compressor overheating. If problem repeats, call Customer Service at 1-800-343-9463.
Compressor runs but evaporator fan does not
Possible cause| Solution
Faulty fan motor| Contact us at [email protected]
Faulty controller| Contact us at [email protected]
Compressor short cycles
Possible cause| Solution
Evaporator blows on bottle probe| Move bottle probe to a more central location
Unit low on refrigerant charge| Contact us at [email protected]
Condensing fan motor/capacitor faulty| Contact us at [email protected]
Compressor and/or starting components faulty| Contact us at [email protected]
Humidity in cellar too low
Possible cause| Solution
Not enough moisture| Raise the Fdc setting to increase the humidity level
