YOUR COMFORT SYSTEM
A. identifying Your System
Take the time to familiarize yourself with your packaged air conditioning system. This knowledge will be of use in understanding the basic
operation of your new air conditioner. The unit has a rating plate alTixed to it which provides necessary inlk_rmation lk_rspecific identification of
a unit. You should liunilialize yourself with the product, model, and serial numbers listed on each rating plate. Record them lk_rluture relerence
in the space provided at the end of this booklet.
iMPORTANT FACTS
To better protect your investment and to elindnate unnecessary calls, familiarize yourself with the lk_llowing lhcts:
1. Your air conditioning system should never be operated without a clean air filter properly installed. Plan to inspect the filter periodically.
A clogged air filter will increase operating costs and shorten the lili_ of the unit.
2. Supply-air and return-air registers should not be blocked. Drapes, furniture, and toys are some of the items commonly lkmnd obstructing
registers. Restricted airflow lessens the unit's efl]cieucy and lili_ span.
3. The outdool: unit nmst have unrestricted airflow. Do not cover the unit, lean anything against it, or stand on it. Do not allow grass clippings,
leaves, or other debris to accumulate around on top of the unit. Maintain a 30-in. u_inimum clearance between the outdoor unit and tall grass,
vines, shrubs, etc.
4. Your multipurpose indoor thermostat is the control center lk)r your heat pump system. You should fandliarize yourself with its proper
operation. Attempting to control the system by other means lk)r instance, switching the electrical supply power ON and OF_may cause
damage to the unit (See Fig. 3).
5. You may find that you can maintain greater personal comlk)rt by rtmning the fan continuously. "Air pockets" can limn due to the structure
of the house, placement of registers, etc. air pockets may be too cool or warm liar your liking. Continuous fan operation minimizes any
ten_perature dil_erences. Also, systems equipped with electronic or mechauical air cleaners and/or humidifiers ol_i:r the added benefits of
having the air continuously cleaned year-round aud humidified during the winter season.
6. Your air conditioner will remove humidity l_'om your home during the cooling season. After a li:w ndnntes of operation, yon should be able
to see water trickle from the condensate drain. Check this occasionally to be sure the drain system is not clogged. Of course, don't expect
to see much drainage if you live in a very dry environment.
A WARNING: FiRE AND ELECTRICAL HAZARD
Failure to follow this warning could result in personal injury, death and/or property damage.
To prevent serious injury, death, or property damage, read and follow all instructions and warnings, including labels shipped
with or attached to unit before operating your new heat pump.
OPERATING YOUR AiR CONDITIONER
The operation of your air conditioning system is controlled by the indoor therlnostat. You simply adjust the thermostat and it maintains the indoor
temperature at the level you select. Most thermostats liar air conditioning systems have 3 controls: a temperature control selector, a FAN control,
and a SYSTEM or MODE coutroh
B. Cooling Mode
When operating in cooling mode, your air conditioner will run in cooling mode until the indoor temperature is lowered to the level you have
selected. On extremely hot days, your air conditioner will run lbr longer periods at a time and have shorter "olT' periods than on moderate days.
The lbllowing are typical conditions that add extra heat and/or humidity to your home. Your air conditioner will work longer to keep your home
comlk_rtable under these conditions:
1. Entrance doors are fi'eqnently opened and closed
2. Laundry appliances am being operated
3. A shower is running
4. More than the usual number of people are present in the home
5. More than the normal number of electric lights are in use
6. Drapes are open on the sunny side of the home

morn temperature is raised to the level you have selected. Of course, the heating unit will have to operate IT)rlonger periods to maintain a
eomlT>rtable environment on colder days and nights than on moderate ones.
PERFORMING ROUTINE MAINTENANCE
With the proper maintenance and care, your air eondifioner will operate economically and dependably. Maintenance can be accomplished easily
by reierring to the IT_llowing directions. However, belT>re perlT_rming maintenance, consider these important saiety precautions:
,/K WARNING: ELECTRICAL SHOCK HAZARD
Failure to fo((ow this warning could result in personal injury and/or death.
Disconnect all electrical power to the indoor air handier or furnace before remowng access panels to perform any
maintenance. Disconnect power to both the indoor and outdoor units. Note: There may be more than 1 electrical disconnect
switch.
/K CAUTION: PERSONAL INJURY HAZARD
Failure to follow this caution may result in personal injury.
Although special care has been taken to minimize sharp edges in the construction of your unit, to avoid injury be extremely
careful when handling parts or reaching into the unit.
D. Check the Air Filter
A dirty air l]lter will cause excessive strain on tire compressor and blower motor. This can cause tire components to overheaI and automatically
slant down. In the worst case, the components will fail and need to be replaced. To avoid inellicient or failed operation of your unit, CHECK THE
FILTER(S) EVERY 3 MONTHS. Replace filter(s) when necessary, or clean the filter(s) if you have the reusable type.
Disposable filters should be replaced by similar, new filters of the same dimensions.
Reusable, permanent filters should be washed in a solution of cold water and mild detergent, then rinsed and thoroughly dried. THE FILTER
MUST BE COMPLETELY DRY BEFORE BEING REINSTALLED. To avoid prolonged shutdown of your unit while a filter is drying, you
should have an extra filter on hand. This allows you to rotate between the two with minimal downtime IT)ryour comlT)rt system. Extra filters may
be purchased from your dealer.
The filters(s) and l]lter rack IT>ra packaged system are supplied and installed by the contractor or dealer. Typically, the filter(s) and rack are located
in the return-air duct at the outdoor unit or behind the return-air grille(s). Have your dealer show you the location of your filter(s) and the
procedures lbr removal and replacement.
If your system includes a high elTicieney or electronic air cleaner, rel_:r to air cleaner User's Manual lor proper filter cleaning or replacement.
E, Outdoor Coil
If grass clippings, leaves, shrubbery, and debris are kept away from the unit, minimal care should be sull]cient to keep tire systen-i functioning
properly. However, if the outdoor coil becomes dirty, use a vacuum cleaner or shop vac with soft brush attachment to clean the exterior surlhee.
Vacuum coil surface using an up and down motion. Be careful not to bend or damage fins.
If dirt is deep in the coil, contact your dealer IT>rservice. Do not attempt this yourself.
g. Outdoor Coil--Sea Coast
If your unit is located near the ocean, special n-laintenanee is required. Ocean mist/breeze carries salt, which is corrosive to most metals. Although
your new unit is made out of galvanized metal and is protected by top-grade paint, you should take the precaution of additional maintenance which
consists of periodically washing the unit. By washing all exposed surfaces and coil, you will be adding additional liie to your unit. Please consult
your installing contractor IT>rproper intervals/procedures IT_ryour geographic area or service contact.
G. UNiT SUPPORT
Your packaged air condith>nhlg unit should be lnahltained at a level position. If its support should shi[_ or settle so that tire unit is no longer level,
you should correct the condition. Relevel it promptly to assure water drains out of the unit. If you notice that waIer or ice collects beneath the unit,
arrange IT>rit to be drained away from the unit.
