Starting or Shutting Unit Off

To start the unit:

1.Turn on the electrical power supply to unit.

2.Select temperature and set MODE control to desired mode.

To shut unit off:

Note: If the unit is being shut down because of a malfunction, call your dealer as soon as possible.

1.Set system MODE control to OFF.

2.Turn off the electrical power supply to unit.

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 SYS- TEM or MODE control. Refer to your thermostat owner’s manual for more information.

To better protect your investment and to eliminate unnecessary ser- vice calls, familiarize yourself with the following facts:

Step 1—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.

Step 2—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 or- der 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 deal- er. 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
