To prevent injury, death, or property damage, read
and follow all instructions and warnings, including
labels shipped with or attached to unit before
operating your new air conditioning system.
Proper maintenance for maximum efficiency
A central air conditioner is not a house-
hold appliance. It’s a self-contained
system that requires professional
maintenance and repair.
That’s why attempts at “do-it-yourself”
repairs on an in-warranty unit may void
the remainder of your warranty.
Other than performing the simple main-
tenance recommended in this manual,
you should not attempt to make any
adjustments to your central air condi-
tioning system. Your dealer will be able
to take care of any questions or
problems you may have.
*Before removing the filter, see the owners
manual furnished with the indoor unit.
How to remove your filter.*
Ask your American Standard dealer
where the filter is located in your system
and how to service it.
Just be sure to replace it with the arrows
pointing in the direction of the air flow.
Call your dealer for additional
routine maintenance
Your air conditioning system should be
inspected regularly by a properly trained
service technician. The inspection
(preferably twice each year, but at
least once a year) should include the
following:
• Routine inspection of air filter(s).
Replacement or cleaning as required.
• Inspection and cleaning of the blower
wheel, housing, and motor as
required.
• Inspection and, if required, cleaning
of indoor and outdoor coils.
• Inspection of the indoor coil drain pan,
plus the primary and secondary drain
lines. If supplied, the auxiliary drain
pan and line should be inspected at
this time. Service should include
cleaning, if required.
Help ensure top efficiency by
cleaning or replacing the
filter monthly.*
When the air conditioner circulates and
filters the air in your home, dust and dirt
particles build up on the filter. Excessive
accumulation can block the air flow,
forcing the unit to work harder to
maintain desired temperatures. And
the harder your unit works, the more
energy it uses.
Clean or replace your filter twice a
month during seasons when the unit
runs more often.
When replacing your filter(s), always
use the same size and type that was
originally supplied. Filters are available
from your dealer.
Where disposable filters are used, they
must be replaced every month with
the same size as originally supplied.
Efficiency can be maintained by
keeping outdoor unit clear of
debris, leaves and shrubbery.
Efficient operation of your air conditioner
depends on the free flow of air over the
coil. Anything that blocks the air flow,
causes the compressor to work harder
to move the warm air out of your house.
To avoid overworking your unit, do not
plant flowers or shrubbery right next to it.
Also, make sure that nothing is stacked
against the sides of the unit or draped
over it.
Making sure your outdoor unit is kept
clear at all times helps it work at peak
efficiency.
Keep your air conditioner
looking new for years.
Clean the enamel finish of your air
conditioner with soap and water. For
stubborn grease spots, use a household
detergent. Do not use lacquer thinner or
other synthetic solvents as they may
damage the finish.
• A check of all electrical wiring and
connections.
• A check for secure physical con-
nections of individual components
within units.
• Operational check for the air condi-
tioning system to determine actual
working condition. Necessary repair
and/or adjustment should be
performed at this time.
• Your servicing dealer may offer an
economical service or preventative
maintenance agreement that covers
seasonal inspections. Ask your
dealer for further details.
Although special care has been taken to minimize
sharp edges in the construction of your unit, be
extremely careful when handling parts or reaching
into the unit.
Condensate drains should be checked and cleaned
periodically to assure condensate can drain freely
from coil to drain. If condensate cannot drain freely,
water damage could occur.
Disconnect all electrical power to the indoor air
handler or furnace before removing access panels
to perform any maintenance. Disconnect power to
both the indoor and outdoor units. NOTE: There
may be more than one electrical disconnect
switch. Electric shock can cause personal injury
or death.
Improper installation, adjustment, alteration,
service, maintenance, or use can cause explosion,
fire, electrical shock, or other conditions which
may cause personal injury or property damage.
Consult a qualified installer or service agency for
information or assistance. The qualified installer
or agency must use factory-authorized kits or
accessories when modifying this product.
