NOTE: Installer: This manual should be left with the equipment user.
Operating Your Unit
The operation of your heat pump system is controlled by the indoor
thermostat. You simply adjust the thermostat and it maintains the indoor
temperature at the level you select. Most thermostats of heat pump
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:
1. During heating, increasing the desired temperature setting more
than 2°F (1.1°C) may cause the supplemental heaters to be turned
on for a short period of time to satisfy the demand. Needless use of
the supplementary heat reduces potential energy savings.
2. Ice or frost tends to form on the coil during winter heating
operation. Your unit is designed to automatically melt the ice. When
in this defrost cycle, it is normal for steam or fog to rise from the
outdoor unit, and for water to drain from the outside of unit. Do not
be alarmed!
To start the unit:
1. Turn on the electrical power supply to unit.
2. Set MODE control to desired mode and select temperature.
To shut off unit:
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.
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.
Maintenance and Service
This section discusses maintenance that should be performed by your
dealer and care you, as the owner, may wish to handle 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:
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 an air filter in place before it can be operated. These
filters should be located in at least one of 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.
Filter kits are available as a purchased accessory or a factory installed
option. The same filter kit is included with the accessory economizers
and factory installed economizers.
To replace or inspect filters in accessory filter rack:
1. Remove the filter access panel (See Fig. 3) using a 5/16-in. nut
driver.
2. Remove the filter(s) by pulling it out of the unit. If the filter(s) is
dirty, clean or replace with a new one.
When installing the new filter(s), note the direction of the airflow arrows
on the filter frame.
If you have difficulty locating your air filter(s) or have questions
concerning proper filter maintenance, contact your dealer for
instructions. When replacing filters, always use the same size and type of
filter that was supplied originally by the installer. See Table 1 for filter
sizes supplied with accessory filter rack.
