COIL CARE
Keep the outdoor unit free of foliage, grass clippings, leaves, paper, and
any other material which could restrict the proper air flow in and out of
the unit. The coil may be vacuumed to remove any debris from between
the fins. If the coil becomes excessively dirty, turn the main disconnect
switch to “Off” and wash the coil with your garden hose. Avoid getting
water into the fan motor and control box. Flush dirt from base pan after
cleaning the coil.
SERVICE CALLS
There are a few instances where the user can avoid unnecessary ser-
vice calls. If unit stops functioning properly check the following items
before calling your servicing dealer:
1. Indoor section for dirty filter.
2. Outdoor section for leaf or debris blockage. Eliminate problem, turn
off the thermostat for 10 seconds and attempt start. Wait 5 minutes.
If system does not start, call your servicing dealer.
FILTER CARE
Inspect the air filter(s) at least once a month. If they are dirty, wash
reusable filters with a mild detergent per manufacturer’s recommenda-
tions. Replace disposable filters with new filters. Install the clean filters
with “air flow” arrow in the same direction as the air flow in your duct.
Filters should be clean to assure maximum efficiency and adequate air
circulation.
CLEARANCES
The minimum clearances shown below must be maintained should any
patio or yard improvements be done around the outdoor unit.

PARTS INFORMATION
Replacement parts are available from local contractor/dealer or the
nearest distribution center.
EXTENDED WARRANTY
Special warranty packages (called York CarePerformance Promise) are
available through your contractor. These packages reduce the potential
cost of service calls following the first year of operation on your cooling
(or heating/cooling) system.
SOME EFFICIENCY DO’S & DON’TS
DON’T heat or cool unused household area. Reduce supply and return
air flow to a minimum in areas which are not living spaces (storage
rooms, garages, basements, etc).
DON’T be a “thermostat jiggler”. Moving your thermostat setting will not
make your system heat or cool any faster. Adjust your thermostat to a
comfortable setting and leave it there.
DON’T restrict air circulation. Placing furniture, rugs, etc. in such a way
that they interfere with air vents will make your system work harder to
achieve a comfortable temperature level. This requires more energy,
which means greater cost to you.
DON’T heat or cool when you are away. If you are going to be away for
a day or more, re-adjust your thermostat accordingly. Your furniture is
far less demanding than you are when it comes to comfort levels. How-
ever, don’t expect the system to restore comfort conditions immediately
upon returning home. It will take a little time.
DON’T locate lamps or other heat-producing appliances (radios, TV’s,
heaters, etc.) near your thermostat. The heat from these items will give
your thermostat “false information” about the temperature in the room.
DO select a comfortable thermostat setting, but keep in mind that mod-
eration in temperature selection will save energy.
DO turn on your kitchen exhaust fan when cooking and your bathroom
exhaust fan when showering. Also, make sure your clothes dryer is
properly vented. If these items are neglected, an excess heat and
humidity condition may be created, causing your air conditioning sys-
tem to run longer.
DO set your thermostat a few degrees lower than normal several hours
before entertaining a large group of people in a relatively small area.
People give off a considerable amount of heat and moisture in a closed
area.
DO keep drapes and venetian blinds closed when practical. These
items provide insulation against heat loss/gain.
DO contact a qualified service person to make repairs or adjustments to
your system. He has been trained to perform this service.
Your system contains environmentally friendly refrigerant R-
410A, which operates at high pressures. You may be in dan-
ger if you try to make an attempt to repair your unit. Please
contact your local dealer.
