ROUTINE MAINTENANCE
NOTE: Units are to be inspected and serviced by qualified service personnel only.
Routine maintenance is required annually or semi-annually, depending upon annual usage.
1.Clean the unit air intake filter at least every 250 to 300 fan hours of operation or when the unit’s indicator light is on if so equipped. Clean the filters with a mild detergent in warm water and allow to dry thoroughly before reinstalling.
2.The indoor coil (evaporator coil), the outdoor coil (condenser coil) and base pan should be inspected periodically (yearly or bi-yearly) and cleaned of all debris (lint, dirt, leaves, paper, etc.). Clean the coils and base pan with a soft brush and compressed air or vacuum. If using a pressure washer, be careful not to bend the aluminium fin pack. Use a sweeping up and down motion in the direction of the vertical aluminum fin pack when pressure cleaning coils. Cover all electrical components to protect them from water or spray. Allow the unit to dry thoroughly before reinstalling it in the sleeve.
NOTE: Do not use a caustic coil cleaning agent on coils or base pan. Use a biodegradable cleaning agent and degreaser.
Inspect the indoor blower housing, evaporator blade, condenser fan blade, and condenser shroud periodically (yearly or bi-yearly) and clean of all debris (lint, dirt, mold, fungus, etc.) Clean the blower housing area and blower wheel with an antibacterial / antifungal cleaner. Use a biodegradable cleaning agent and degreaser on condenser fan and condenser shroud. Use warm or cold water when rinsing these items. Allow all items to dry thoroughly before reinstalling them.
3.Periodically (at least yearly or bi-yearly): inspect all control components, both electrical and mechanical, as well as the power supply. Use proper testing instruments (voltmeter, ohmmeter, ammeter, wattmeter, etc.) to perform electrical tests. Use an air conditioning or refrigeration thermometer to check room, outdoor and coil operating temperatures. Use a sling psychrometer to measure wet bulb temperatures indoors and outdoors.
4.Inspect the surrounding area (inside and outside) to ensure that the units’ clearances have not been compromised or altered.
5.Inspect the sleeve and drain system periodically (at least yearly or bi-yearly) and clean of all obstructions and debris. Clean both areas with an antibacterial and antifungal cleaner. Rinse both items thoroughly with water and ensure that the drain outlets are operating correctly. Check the sealant around the sleeve and reseal areas as needed.
6.Clean the front cover when needed. Use a mild detergent. Wash and rinse with warm water. Allow it to dry thoroughly before reinstalling it in the chassis.

DATA PERFORMANCE
ELECTRICAL DATA
Wire Size |
Use ONLY wiring size recommended for |
|
single outlet branch circuit. |
Fuse/Circuit |
Use ONLY type and size fuse or HACR |
Breaker |
circuit breaker indicated on unit’s rating |
|
plate. Proper current protection to the unit |
|
is the responsibility of the owner. |
Grounding |
Unit MUST be grounded from branch |
|
circuit through service cord to unit, or |
|
through separate ground wire provided on |
|
permanently connected units. Be sure that |
|
branch circuit or general purpose outlet is |
|
grounded. |
Receptacle |
The field supplied outlet must match plug on |
|
service cord and be within reach of service |
|
cord. Do NOT alter the service cord or plug. |
|
Do NOT use an extension cord. Refer to |
|
the table above for proper receptacle and |
|
fuse type. |
ELECTRIC SHOCK HAZARD.
Turn off electric power before service or installation.
All electrical connections and wiring MUST be installed by a qualified electrician and conform to the National Electrical Code and all local codes which have jurisdiction.
Failure to do so can result in property damage, personal injury and/or death.
The consumer - through the AHAM Room Air Conditioner Certification Program - can be certain that the AHAM Certification Seal accurately states the unit’s cooling and heating capacity rating, the amperes and the energy efficiency ratio.

FUNCTIONAL COMPONENTS
A. Mechanical components
Bellows condensate valve
Temperature-sensitive valve that opens up to drain off condensate water when the outside temperature falls below 40°F and closes when the outside temperature reaches 58°F.
Plenum assembly
Diffuser with directional louvers used to direct the conditioned airflow.
Blower wheel
Attaches to the indoor side of the fan motor shaft and is used for distributing unconditioned, room side air though the heat exchanger and delivering conditioned air into the room.
Slinger fan blade
Attaches to the outdoor side of the fan motor shaft and is used to move outside air through the condenser coil, while slinging condensate water out of the base pan and onto the condenser coil, thus lowering the temperature and pressures within the coil.
B. Electrical components
Thermostat
Used to maintain the specified room side comfort level
System switch
Used to regulate the operation of the fan motor, the compressor or to turn the unit off. For troubleshooting, refer to the wiring diagrams and schematics in the back of this service manual.
Capacitor
Reduces line current and steadies the voltage supply, while greatly improving the torque characteristics of the fan motor and compressor motor.
MoneySaver® switch
When engaged, it sends the power supply to the fan motor through the thermostat, which allows for a cycle-fan operation.
Fan Motor
Dual-shafted fan motor operates the indoor blower wheel and the condenser fan blade simultaneously.
Solenoid
Used to energize the reversing valve on all heat pump units.
Heating element
Electric resistance heater, available in 3.3, 4.0 or 5.2 kW on select TwinTemp® models.
Heat anticipator
Used to provide better thermostat and room air temperature control.
C. Hermetic components
Compressor
Motorized device used to compress refrigerant through the sealed system.
Reversing valve
A four-way switching device used on all heat pump models to change the flow of refrigerant to permit heating or cooling.
Check valve
A pressure-operated device used to direct the flow of refrigerant to the proper capillary tube, during either the heating or cooling cycle.
Capillary tube
A cylindrical meter device used to evenly distribute the flow of refrigerant to the heat exchangers (coils.)
