OPERATING YOUR UNIT
The operation of your system is controlled by the indoor
temperature control (Thermostat).You simply adjustthethermostat
and it maintainsthe indoor temperature at the levelyou select.Most
thermostats of heating and cooling systems have 3 controls: a
temperature control selector, a FAN control, and a System or
MODE control. Refer to your thermostat owner’s manual for more
information.
To better protect your investment and to eliminate unnecessary
service calls, familiarize yourself with the following facts:
Cooling Mode
With the SYSTEM or MODE control set to COOL, your unit will
run in cooling mode until the indoor temperature is lowered to the
level you have selected. On extremely hot days, your unit will run
for longer periods at a time and have shorter “off” periods than on
moderate days.
Gas Heating Mode
With the SYSTEM or MODE control of your indoor thermostat set
to HEAT, your unit willrunin heating mode untiltheroomtemperatureisraisedto the level you have selected. On cold days andnights,
your system will typically run for longer periods of time and have
shorter “off”periods than on moderatedays. This is the same as the
COOLING MODE.
MAINTENANCE AND SERVICE
This section discusses maintenance that should be performed on
your system.Most maintenanceshould be performed by your dealer. You, as the owner,may wish to handle some minor maintenance
for your new unit.
Routine Maintenance
All routine maintenance should be handledby skilled, experienced
personnel. Your dealercan help you establish a standardprocedure.
For your safety, keep the unit area clear and free of combustible
materials, gasoline, and other flammable liquids and vapors.
To assure proper functioning of the unit, flow of condenser air must
not be obstructed from reaching the unit. Clearance from the top of
the unit is 48 in. (1219 mm). Clearance of at least 36 in. (914 mm)
is required on sides except the power entry side (42 in. clearance)
(1067mm) and the duct side(12in.minimumclearance) (305 mm).
Maintenance and Care for the Equipment Owner
Before proceeding with those things you might want to maintain
yourself, please carefully consider the following:
!
WARNING
FIRE, EXPLOSION, ELECTRICAL SHOCK AND
CUT HAZARD
Failure to follow this warning could result in personal injury,
death or property damage.
1. TURN OFF ELECTRICAL POWER TO YOUR UNIT
BEFORE SERVICING OR PERFORMING
MAINTENANCE.
2. When removing access panels or performing maintenance
functions inside your unit, be aware of sharp sheet metal
parts and screws. Although special care is taken to reduce
sharp edges to a minimum, be extremely careful when
handling parts or reaching into the unit.
Air Filters
The air filter(s) should be checked every 3 or 4 weeks and changed
or cleaned whenever it becomes dirty. Dirty filters produce excessive stress on the blower motor and can cause the motor to overheat
and shut down.
This unit must have air filters in place before it can be operated.
These filters can be located in one of at least two places. In many
applications, the installer will provide return air filter grilles
mounted on the wall or ceiling of the conditioned structure. In the
instance of filter grilles, the filters can simply be removed from the
grille and replaced.
The other typical application is an accessory filter rack installed
inside the unit itself. The following information is given to assist in
changing filters used in these internal filter racks.
Table1 indicatesthe correct indoor filter size for your unit. Refer to
Fig. 2 to access filters installed in the accessory filter rack. If using
an Accessory Filter Rack, refer to the Installation Instructions
provided with it for correct filter sizes and quantities.
