HOMEOWNER’S ROUTINE MAINTENANCE RECOMMENDATIONS
PACKAGE UNITS - Dual Fuel & Gas
HOMEOWNER’S Routine Maintenance Recommendations
We strongly recommend a bi-annual maintenance checkup be performed by a qualified service agency before the heating and cooling seasons begin
WARNING
HIGH VOLTAGE
Disconnect all power before servicing or
installing this unit. Failure to do so may cause
property damage, personal injury or death.
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 non-electronic types. These filters can do a better job
of catching small airborne particles.
Improper filter maintenance is the most common cause of
inadequate heating or cooling performance. Filters should
be cleaned (permanent) or replaced (disposable) every two
months or as required. 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
require 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.
