OPERATING YOUR UNIT
The operation of your unit is controlled by indoor thermostat. You
simply adjust the thermostat and it maintains the indoor
temperature at the level you select. Most thermostats of 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.
Heating Mode (if installed with optional electric
heat)
Your system may also be equipped with an electric heating source.
On cold days and nights, place your MODE control to HEAT and
your system will automatically turn on the supplemental heat in
order to maintain the level of comfort you have selected.
MAINTENANCE AND SERVICE
This section discusses maintenance that should be performed on
your system. Most maintenance should 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 handled by skilled, experienced
personnel. Your dealer can help you establish a standard procedure.
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. (1067
mm) clearance) and the duct side (12 in. (305 mm) minimum
clearance).
Maintenance and Care for the Equipment Owner
Before proceeding with those things you might want to maintain
yourself, please carefully consider the following:
CUT HAZARD
Failure to follow this caution may result in personal injury,
death.
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.
FIRE, EXPLOSION,ELECTRICALSHOCK
HAZARD
Failureto follow this warning could result in personal
iniury, death or property damage.
1. TURN OFF ELECTRICAL POWER TO YOUR UNIT
BEFORE SERVICING OR PERFORMING
MAINTENANCE AND INSTALL A LOCKOUT TAG.
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.
Table 1 indicates the 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.
