Johnson Controls Ducted Systems
FILTER CARE
Inspect the air filters at least once a month. If they are dirty, wash reus-
able filters with a mild detergent per manufacturer’s recommendations.
Replace disposable filters with new filters. Install the clean filters with
the
air flow
arrow in the same direction as the air flow in your duct. Fil-
ters must be clean to assure maximum efficiency and adequate air cir-
culation.
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.
EXTENDED WARRANTY
Special warranty packages (called YORK Care Performance 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 DOS AND DO NOTS
Do not
heat or cool unused household area. Reduce supply and return
air flow to a minimum in areas which are not living spaces, such as stor-
age rooms, garages, or basements.
Do not
be a
thermostat jiggler
. Moving your thermostat setting does not
make your system heat or cool any faster. Adjust your thermostat to a
comfortable setting and leave it there.
Do not
restrict air circulation. Placing furniture, rugs, and other objects
in such a way that they interfere with air vents makes your system work
harder to achieve a comfortable temperature level. This requires more
energy, which means greater cost to you.
Do not
locate lamps or other heat-producing appliances such as radios,
TV’s, or heaters near your thermostat. The heat from these items gives
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 saves energy.
Do
turn on your kitchen exhaust fan when cooking and your bathroom
exhaust fan when showering. Also, make sure your clothes dryer is cor-
rectly vented. If you neglect these items, this may create an excess
heat and humidity condition, causing your air conditioning system 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.
CHARACTERISTICS OF HEAT PUMPS
A CONSTANT HEAT
Heat pumps have a noticeable cooler supply air temperature than fur-
naces. The common practice of over-sizing furnaces contributes to an
off-and-on again
operation with short blasts of hot supply air. The heat
pump system is sized more closely to the heating needs of your home.
Heat is supplied at a lower temperature over a longer period of time to
provide a more constant heat, and it may give you the impression that
your system never stops running.
WATER RUN-OFF
During the heating cycle, in mild weather you may notice water running
off the outdoor coil. Moisture from the air is condensed on the outside
surface of the coil where it gathers and runs off. This is no need for
alarm and your unit is not leaking.
OUTDOOR COIL DEFROSTING
At certain outdoor conditions (low temperature, high humidity), frost
may build up on the coil of the outdoor unit. In order to maintain heating
efficiency, the system automatically defrosts itself. Steam rising from the
outdoor unit is normal and is an indication of proper operation. The
vapor cloud only lasts for a few minutes. When the defrost cycle is com-
pleted, the system automatically switches back to heating. Auxiliary
heat is automatically energized to maintain comfort during defrost.
