R . INFORMATION FOR THE OWNER
R.1 Routine Maintenance
Coils & Chassis
NOTE:
Do not use a caustic cleaning agent on coils or base pan. Use a
biodegradable cleaning agent and degreaser. The use of harsh
cleaning materials may lead to deterioration of the aluminum
fins or the coil end plates.
The indoor coil and outdoor coils and base pan should be inspected
periodically (annually or semi-annually) and cleaned of all debris (lint,
dirt, leaves, paper, etc.) as necessary. Under extreme conditions, more
frequent cleaning may be required. Clean the coils with and base pan
with a coil comb or soft brush and compressed air or vacuum. A low
pressure washer device may also be used; however, you must be careful
not to bend the aluminum fin pack. Use a sweeping up and down motion
in the direction of the vertical aluminum fin pack when pressure cleaning
coils.
NOTE:
It is extremely important to insure that none of the electrical
and/ or electronic parts of the unit get wet when cleaning. Be
sure to cover all electrical components to protect them from
water or spray.
Decorative Front
Use a damp (not wet) cloth when cleaning the control area to prevent
water from entering the unit, and possibly damaging the electronic
control.
The decorative front and the cabinet can be cleaned with warm water
and a mild liquid detergent. Do NOT use solvents or hydrocarbon based
cleaners such as acetone, naphtha, gasoline, benzene, etc.
The indoor coil can be vacuumed with a dusting attachment if it appears
to be dirty. DO NOT BEND FINS. The outdoor coil can be gently sprayed
with a garden hose.
Air Filter
The air filter should be inspected weekly and cleaned if needed by
vacuuming with a dust attachment or by cleaning in the sink using warm
water and a mild dishwashing detergent. Dry the filter thoroughly before
reinstalling. Use caution, the coil surface can be sharp.
CAUSE
This may be due to an excessive heat load in the
room.
It may also be due to an improperly sized unit.
This may be normal for higher efficiency (EER) air
conditioners.
You may notice that the discharge air
temperature of your new air conditioner may
not seem as cold as you may be accustomed
to from older units. This does not; however,
indicate a reduction in the cooling capacity of
the unit.
M. TROUBLESHOOTING
•
If there are heat producing appliances in use in the room, or if the
room is heavily occupied, the unit will need to run longer to remove the
additional heat.
•
Be sure to use exhaust vent fans while cooking or bathing and, if
possible, try not to use heat producing appliances during the hottest part
of the day.
•
The use of higher efficiency components in your new air conditioner
may result in the unit running longer than you feel it should. This may be
more apparent, if it replaced an older, less efficient, model. The actual
energy usage, however, will be significantly less when compared to
older models.
•
The energy efficiency ratio (EER) and cooling capacity rating (Btu/ h)
listed on the unit's rating plate are both agency certified.
Blower Wheel / Housing / Condensor Fan / Shroud
WARNING:
Service of this product (aside from filter maintenance)
shall only be performed by trained service personnel. Refer to the Service
Manual for procedures on how to inspect and maintain the interior of the
unit and its components. A QR code is located in section A.4 which will help
you locate the service manual online.
Inspect the indoor blower and its housing, evaporator blade, condenser
fan blade and condenser shroud periodically (yearly or bi-yearly) and
clean of all debris (lint, dirt, mold, fungus, etc.). Under extreme conditions,
more frequent cleaning may be necessary. 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.
