DANGER
PELIGRO

CARBON MONOXIDE POISONING HAZARD

Special Warning for Installation of Furnace or Air Handling Units in Enclosed Areas such as Garages, Utility Rooms or Parking Areas Carbon monoxide producing devices (such as automobiles, space heater, gas water heater, etc.) should not be operated in  enclosed areas such as unventilated garages, utility rooms or parking areas because of the danger of carbon monoxide (CO) poisoning resulting from the exhaust emissions. If a furnace or air handler is installed in an enclosed area such as a garage, utility room or parking area and a carbon monoxide producing device is operated therein, there must be adequate, direct outside ventilation.
This ventilation is necessary to avoid the danger of CO poisoning which can occur if a carbon monoxide producing device continues to operate in the enclosed area. Carbon monoxide emissions can be (re)circulated throughout the structure if the furnace or air handler is operating in any mode.
CO can cause serious illness including permanent brain damage or death.

PRE-INSTALLATION INSTRUCTIONS

5.1 Preparation
Keep this document with the unit. Carefully read all instructions for the installation prior to installing product. Make sure each step or procedure is understood and any special considerations are taken into account before starting installation. Assemble all tools, hardware, and supplies needed to complete the installation. Some items may need to be purchased locally. Make sure everything needed to install the product is on hand before starting.

5.2 System Matches
The entire system (combination of indoor and outdoor sections) must be manufacture approved and Air-conditioning, Heating, and Refrigeration Institute (AHRI) listed.

NOTE: Installation of unmatched systems is not permitted. Damage or repairs due to installation of unmatched systems is not covered under the warranty.

5.3 Interconnecting Tubing
Give special consideration to minimize the length of refrigerant tubing when installing air handlers. Refer to Remote Cooling/ Heat Pump Service Manual RS6200006, and TP107 Long Line Set Application R-410A for tubing guidelines.
If possible, allow adequate length of tubing such that the coil may be removed (for inspection or cleaning services) from the cabinet without disconnecting the tubing.
Note: These air handlers are designed for indoor installation only at a max altitude of 10,500 feet above sea level or a min altitude of -184 feet below sea level.
If the unit is located in an unconditioned area with high ambient temperature and/or high humidity, the air handler may be subject to nuisance sweating of the casing. On these installations, a wrap of 2” fiberglass insulation with a vapor barrier is recommended. A secondary drain pan below the unit is also recommended to protect the installation site.

5.4 Clearances
The unit clearance from a combustible surface may be 0”. However, service clearance must take precedence. A minimum of 24” in front of the unit for service clearance is required. Additional clearance on one side or top will be required for electrical wiring  connections. Consult all appropriate regulatory codes prior to determining final clearances. When installing this unit in an area that may become wet (such as crawl spaces), elevate the unit with a sturdy, non-porous material. In installations that may lead to physical damage (i.e. a garage) it is advised to install a protective barrier to prevent such damage. Always install units such that a positive slope in condensate line (1/4” per foot) is allowed.

APPLICATION INFORMATION

The unit is designed to be installed in conditioned space, either recessed into a wall or hanging in a vertical “upflow” position. If units are recessed in a wall, use the holes along the inside of the front flange to attach units to the framing studs. The vertical air handler comes equipped with an offset hanging bracket attached to the rear of the cabinet for hanging applications.
IMPORTANT: Unit must be installed level or slightly tilted back to ensure proper drainage of condensate.
The air handler also has a bottom and front return. Large chassis installations should be installed as front return only. If the small chassis air handler is to be installed in a bottom return application, discard the drain access panel in the bottom of the unit. If the air handler is to be installed in a front return application, remove and discard the front access panel with insulation. The unit is shipped with a filter rack and filter. Remember to inspect, clean and/or replace the filter monthly.

Units are equipped with both a bottom primary and secondary drain. Both drains must be trapped, unless emergency condensate switch is install in the secondary drain. Failure to install a trap could result in condensation overflowing the drain pan resulting in substantial water damage to the nearby area.

The connectors required are 3/4” NPT male, either PVC or metal pipe, CPVC piping is not approved, and should be hand tightened to a torque of no more than 37 in-lbs. to prevent damage to the drain pan connection.
To prevent potential sweating and dripping on to finished space, it may be necessary to insulate the condensate drain line located inside the building. Use Armaflex® or similar material.

NOTE: If you intend to install this unit with a “WAD” door it must be mounted 1/4” behind front edge of stud.

ELECTRICAL AND CONTROL WIRING

IMPORTANT: All routing of electrical wiring must be made through provided electrical knockouts. Do not cut, puncture or alter the cabinet for electrical wiring.

WARNING

 TO AVOID THE RISK OF FIRE OR EQUIPMENT DAMAGE, USE ONLY COPPER CONDUCTORS.
DISCONNECT ALL POWER BEFORE SERVICING OR INSTALLING THIS UNIT. MULTIPLE POWER SOURCES MAYBE PRESENT.
THE ELECTRICAL POWER TO THIS UNIT MUST BE IN THE OFF POSITION AND ALL POWER SUPPLIES DISCONNECTED.
FAILURE TO DO SO MAY CAUSE PROPERTY DAMAGE, PERSONAL INJURY OR DEATH.
WARNING
THE UNIT MUST HAVE AN UNINTERRUPTED, UNBROKEN ELECTRICAL GROUND TO MINIMIZE THE POSSIBILITY OF PERSONAL INJURY IF AN ELECTRICAL FAULT SHOULD OCCUR. THE ELECTRICAL GROUND CIRCUIT MAY CONSIST OF AN APPROPRIATELY SIZED ELECTRICAL WIRE CONNECTING THE GROUND LUG IN THE UNIT AND CONTROL BOX WIRE TO THE BUILDING’S ELECTRICAL SERVICE PANEL. OTHER METHODS OF GROUNDING ARE PERMITTED IF PERFORMED IN ACCORDANCE WITH THE “NATIONAL ELECTRIC CODE” (NEC)/”AMERICAN NATIONAL STANDARDS INSTITUTE” (ANSI)/”NATIONAL FIRE PROTECTION ASSOCIATION” (NFPA) 70 AND LOCAL/STATE CODES. IN CANADA, ELECTRICAL GROUNDING IS TO BE IN ACCORDANCE WITH THE CANADIAN ELECTRIC CODE CSA C22.1. FAILURE TO OBSERVE THIS WARNING CAN RESULT IN ELECTRICAL SHOCK THAT CAN CAUSE PERSONAL INJURY OR DEATH.

7.1 Building Electrical Service Inspection
This unit is designed for single-phase electrical supply.

NOTE: DO NOT OPERATE ON A THREE-PHASE POWER SUPPLY.

Measure the power supply to the unit. The supply voltage must be in agreement with the unit name plate power requirements and within the range shown in Table 1.

7.2 Wire Sizing
Wire size is important to the operation of your equipment.
Use the following checklist when selecting the appropriate wire size for the unit.

• Wire used must cary the Minimum circuit Ampacity (MCA) listed on the unit’s Series and Rating Plate.
• Refer to the NEC (USA) or CSA (Canada) for wire sizing. The unit MCA for the air handler and the optional electric heat kit can be found on the unit Series and Rating Plate.
• Wire must be sized to allow no more than a 2% voltage drop from the building breaker/fuse panel to the unit.
• Wires with different insulation temperature rating have varying ampacities – be sure to check the temperature rating used.

Refer to the latest edition of the National Electric Code or in Canada the Canadian Electric Code when determining the correct wire size.

7.3 Maximum Overcurrent Protection (MOP)
Every installation must include an NEC (USA) or CEC (Canada) approved overcurrent protection device. Also, check with local or state codes for any special regional requirements. Protection can be in the form of fusing or HACR style circuit breakers. The Series and Rating Plate can be used  as a guide for selecting the MAXIMUM overcurrent device.

NOTE: Fuses or circuit breakers are to be sized larger than the equipment MCA but not to exceed the MOP.

IMPORTANT NOTE: Torch heat required to braze tubes of various sizes is proportional to the size of the tube.
Tubes of smaller size require less heat to bring the tube to brazing temperature before adding brazing alloy. Applying too much heat to any tube can melt the tube. Service personnel must use the appropriate heat level for the size of the tube being brazed.

NOTE: The use of a heat shield when brazing is recommended to avoid burning the serial plate or the finish on the unit. Heat trap or wet rags should be used to protect heat sensitive components such as service valves and TXV valves.

7.4 Electrical Connections – Supply Voltage

CAUTION
FIRE HAZARD!
TO AVOID THE RISK OF PROPERTY DAMAGE, PERSONAL INJURY OR FIRE, USE ONLY COPPER CONDUCTORS.

IMPORTANT NOTE: Use copper conductors only from disconnect or electrical panel to the air handler.
A knockout is provided on the air handler top panel or side to allow for the entry of the supply voltage conductors. If the knockouts on the cabinet sides are used for electrical conduit, an adapter ring must be used in order to meet safety requirements. An NEC or CEC approved strain relief is to be used at this entry point. The wire is to be sized in accordance with the “Electrical Wire and MOP” section  of this manual. Some areas require the supply wire to beenclosed in conduit. Consult your local codes.

7.5 Fresh Air Openings
All AWSF/AWST models include 4” fresh air knockouts on both sides of the cabinet. To utilize, simply remove the appropriate knockout and connect fresh air inlet venting directly to cabinet. Ensure the unit mounting system does not block the fresh air inlet holes.
NOTE: The installing contractor must take into account any lost capacity due to the the fresh air openings when sizing the equipment.

Table 4

NOTE:

1. Airflow data indicated is at 230V without air filter in place.
2. Select a speed tap that provides a minimum 300 CFM per outdoor ton. For satisfactory operation, external static pressure must no exceed 0.3″ WC (for electric heater only).

EXPANSION VALVE TROUBLESHOOTING

Before replacing an expansion valve, check the following items:

1. Bulb location: Must be tightly secured to the suction line upstream of the equalizer connection.
2. Insulation: Bulb must be properly insulated.
3. Equalizer: Must be connected to the 1/4” SAE connection on the suction line.
4. Charge: Ensure the system is properly charged. There MUST be a minimum of 10°F Sub-Cooled liquid at the valve inlet.

If the system appears to be “starving” (low suction pressure but insufficient cooling):

1. Check the Superheat (SH) at the evaporator outlet. If SH is between 5°F – 12°F, the TXV is controlling properly.
   – Verify that there is proper airflow to the evaporator (fan is operating and filter is unrestricted).

2. If SH is above 12°F, the setting of the TXV may be too high.
   – Adjust the SH by turning counter-clockwise to decrease SH.
   – Wait 20 minutes for the system to balance and adjust again, as required.
   – If adjusting the valve has no effect on the SH, the valve may be stuck because of dirt or debris or it may have lost the Power Element charge.

3. After properly reclaiming the refrigerant, remove the TXV and check for dirt and debris. Clean, if possible, or replace the TXV and filter/drier.

If the system appears to be “flooding” (compressor frosting or moisture is condensing at the suction connection):

1. Check the SH at the evaporator outlet. If SH is between 5°F – 12°F, the TXV is controlling properly.

2. If SH is less than 5°F, the SH adjustment may be too low.
   – Adjust the SH by turning the adjustment stem clockwise to increase the SH.
   – Wait 20 minutes for the system to balance and adjust again as required.
   – If adjusting the valve has no effect on the SH, the valve may be stuck open because of dirt or debris or moisture in the refrigerant.

3. After properly reclaiming the refrigerant, remove the TXV and check for dirt and debris. Clean, if possible, or replace the TXV and filter/drier. Add a moisture indicator to allow checking of moisture if this is believed to be a probable cause.

SPLIT SYSTEMS

AIR CONDITIONING AND HEAT PUMP HOMEOWNER’S ROUTINE MAINTENANCE RECOMMENDATIONS
We strongly recommend a biannual maintenance checkup be performed before the heating and cooling seasons begin by a qualified servicer.
Replace or Clean Filter
IMPORTANT NOTE: Never operate unit without a filter installed as dust and lint will build up on internal parts resulting in loss of efficiency, equipment damage and possible fire.
An indoor air filter must be used with your comfort system. A properly maintained filter will keep the indoor coil of your comfort system clean.
A dirty coil could cause poor operation and/or severe equipment damage.
Your air filter or filters could be located in your furnace, in a blower unit, or in “filter grilles” in your ceiling or walls. The installer of your air conditioner or heat pump can tell you where your filter(s) are, and how to clean or replace them.
Check your filter(s) at least once a month. When they are dirty, replace or clean as required. Disposable type filters should be replaced.
Reusable type filters may be cleaned.
You may want to ask your dealer about high efficiency filters. High efficiency filters are available in both electronic and non-electronic types.
These filters can do a better job of catching small airborne particles.

Compressor
The compressor motor is hermetically sealed and does not require additional oiling.
Motors
Indoor and outdoor fan motors are permanently lubricated and do not require additional oiling.

WARNING
HIGH VOLTAGE
DISCONNECT ALL POWER BEFORE SERVICING OR INSTALLING THIS UNIT. MULTIPLE POWER SOURCES MAY BE PRESENT. FAILURE TO DO SO MAY CAUSE PROPERTY DAMAGE, PERSONAL INJURY OR DEATH.

Aluminum Indoor Coil Cleaning (Qualified Servicer Only)
This unit is equipped with an aluminum tube evaporator coil. The safest way to clean the evaporator coil is to simply flush the coil with water.
This cleaning practice remains as the recommended cleaning method for both copper tube and aluminum tube residential cooling coils.
An alternate cleaning method is to use one of the products listed in the technical publication TP-109* (shipped in the literature bag with the unit) to clean the coils. The cleaners listed are the only agents deemed safe and approved for use to clean round tube aluminum coils. TP-109 is available on the web site in Partner Link > Service Toolkit.
NOTE: Ensure coils are rinsed well after use of any chemical cleaners.

Clean Outside Coil (Qualified Servicer Only)
Air must be able to flow through the outdoor unit of your comfort system. Do not construct a fence near the unit or build a deck or patio over the unit without first discussing your plans with your dealer or other qualified servicer. Restricted airflow could lead to poor operation and/or severe equipment damage.
Likewise, it is important to keep the outdoor coil clean. Dirt, leaves, or debris could also restrict the airflow. If cleaning of the outdoor coil becomes necessary, hire a qualified servicer. Inexperienced people could easily puncture the tubing in the coil. Even a small hole in the tubing could eventually cause a large loss of refrigerant. Loss of refrigerant can cause poor operation and/or severe equipment damage.
Do not use a condensing unit cover to “protect” the outdoor unit during the winter, unless you first discuss it with your dealer. Any cover used must include “breathable” fabric to avoid moisture buildup.

BEFORE CALLING YOUR SERVICER

• Check the thermostat to confirm that it is properly set.
• Wait 15 minutes. Some devices in the outdoor unit or in programmable thermostats will prevent compressor operation for awhile, and then reset automatically. Also, some power companies will install devices which shut off air conditioners for several minutes on hot days. If you wait several minutes, the unit may begin operation on its own.
• Check the electrical panel for tripped circuit breakers or failed fuses. Reset the circuit breakers or replace fuses as necessary.
• Check the disconnect switch near the indoor furnace or blower to confirm that it is closed.
• Check for obstructions on the outdoor unit . Confirm that it has not been covered on the sides or the top. Remove any obstruction that can be safely removed. If the unit is covered with dirt or debris, call a qualified servicer to clean it.
• Check for blockage of the indoor air inlets and outlets. Confirm that they are open and have not been blocked by objects (rugs, curtains or furniture).
• Check the filter. If it is dirty, clean or replace it.
• Listen for any unusual noise(s), other than normal operating noise, that might be coming from the outdoor unit. If you hear unusual noise(s) coming from the unit, call a qualified servicer.

CAUTION
TO AVOID THE RISK OF EQUIPMENT DAMAGE OR FIRE, INSTALL THE SAME AMPERAGE BREAKER OR FUSE AS YOU ARE REPLACING. IF THE CIRCUIT BREAKER OR FUSE SHOULD OPEN AGAIN WITHIN THIRTY DAYS, CONTACT A  QUALIFIED SERVICER TO CORRECT THE PROBLEM.
IF YOU REPEATEDLY RESET THE BREAKER OR REPLACE THE FUSE WITHOUT HAVING THE PROBLEM CORRECTED, YOU RUN THE RISK OF SEVERE EQUIPMENT DAMAGE.
