PACKAGE UNITS - DUAL FUEL & GAS
HOMEOWNER’S ROUTINE MAINTENANCE RECOMMENDATIONS
We strongly recommend a
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.
A return air filter is not supplied with this unit; however, there must be a means of filtering the return air. 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.
The installer of your unit can tell you where your filter(s) are and how to clean or replace them.
Check your return filter(s) at least once every two months. When they are dirty, replace or clean as required. Disposable type filters should be replaced. Reusable type filters may be cleaned. NOTE: Reusable type filters should be washed with warm water, dried completely and sprayed with an adhesive according to the manufacturers recommendations.
You may want to ask your dealer about high efficiency filters. High efficiency filters are available in both electronic and
Improper filter maintenance is the most common cause of inad- equate heating or cooling performance. Filters should be cleaned (permanent) or replaced (disposable) every two months or as re- quired. When replacing a filter, it must be replaced with a filter of the same type and size and always make certain the air flow arrows on the filter point in the proper direction.
CONDENSER, EVAPORATOR AND INDUCED DRAFT MOTORS
The bearings on the air circulating blower motor, condenser motor and the combustion fan motor are permanently lubricated and require no further lubrication.
COMPRESSOR
The compressor motor is hermetically sealed and does not re- quire additional oiling.
ANNUAL INSPECTION (QUALIFIED SERVICER ONLY)
Your package unit should be inspected by a qualified installer, or service agency at least twice every year. This check should be performed before the heating and cooling seasons begin. This will ensure that adequate combustion air is being drawn and the vent system is working properly. Particular attention should be paid to the following items. Repair as necessary.
•Check physical support of the unit. Ensure it is sound without any sagging, cracks, or gaps, around the base.
•Check for obvious signs of deterioration of the unit.
•Flue Hood and Combustion Air Inlet. Check for blockage (wasp nest, etc.) and corrosion.
FLUE HOOD (QUALIFIED SERVICER ONLY)
•Return Air Connection. Check for physical soundness and ensure that the connection is firmly sealed to the package unit casing.
•Heat exchanger. Check for corrosion and/or obstructions within the heat exchanger passageways.
•Burners. Check for proper ignition, burner flame, and flame sense.
•Wiring. Check wires for damage.Check electrical connections for tightness and/or corrosion.
•Filters. Check that filters are clean and in the proper placement in the unit or duct system.
•Louvers. Inspect air inlet louvers inside the heat exchanger compartments. Ensure the area is clean and free of dirt and debris.
CLEAN OUTSIDE COIL (QUALIFIED SERVICER ONLY)
The outdoor coil should be inspected annually. It is important to keep the outdoor coil clean. Dirt, leaves, or debris could 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.
BEFORE CALLING YOUR SERVICER
•Check the thermostat to confirm that it is properly set.
•Check the disconnect switch near the unit to confirm that it is closed.
•Check the electrical panel for tripped circuit breakers or failed fuses . Reset the circuit breakers or replace fuses as necessary.
•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 for obstructions on the 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 the filter. If it is dirty, clean or replace it.
