WARNING

FIRE, EXPLOSION, ELECTRICAL SHOCK

HAZARD

Failure to follow this warning could result in personal injury, death or property damage.

Do not use this unit if any part has been under water.

Immediately call a qualified service technician to inspect the unit and to replace any part of the control system which has been under water.

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.

T o 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 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

With the SYSTEM or MODE control set to HEAT, your unit will run in heating mode until the room temperature is raised to the level you have selected. Of course, your unit will run for longer periods to maintain a comfortable environment on cooler days and nights than on moderate ones.

Supplemental Heat

Your unit is your primary heating source. Your system may also be equipped with a supplemental heating source such as electric heat. On cold days and nights, your system will automatically turn on the supplemental heat, as needed, in order to maintain the level of comfort you have selected.

When your heat pump needs additional heat to keep you comfortable your thermostat will turn on the supplemental heat

(if equipped).

Defrost Mode

When your unit is providing heat to your home or office and the outdoor temperature drops below 45 ° F (7.2

° C), moisture may begin to freeze on the surface of the coil. If allowed to build up, this ice would impede airflow across the coil and reduce the amount of heat absorbed from the outside air. So, to maintain energy − efficient operation, your unit has an automatic defrost mode.

The defrost mode starts at a preset time interval of 60 minutes, although, it may be reset to 30, 90 or 120 minutes. Defrost will start at the preset time only if the ice is sufficient to interfere with normal heating operation.

After the ice is melted from the coil, or after a maximum of 10 minutes in defrost mode, the unit automatically switches back to normal heating operation.

Do not be alarmed if steam or fog appears at the outdoor unit during defrost mode. Water vapor from the melting ice may condense into a mist in the cold outside air.

During certain weather conditions such as heavy snow and freezing rain it is not uncommon for ice to build up on the unit grille. This is normal for these weather conditions. Do not attempt to remove the ice from the unit grille. This condition will not affect the proper function of the unit and will clear within a few days.

Emergency Heating Mode

In the event of primary unit heat failure, the emergency heat mode allows your supplemental heating source to keep your home or office warm until your unit can be serviced. Contact your dealer in the event of primary unit heat failure.

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

Figure 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.
