WARNING
OPERATING YOUR UNIT
The operation of your heat pump system is controlled by the
Infinityr User Interface (UI). You may adjust the temperature
manually through the UI or program the UI for automatic control.
See UI manual for detailed instructions.
Tobetter protectyour investmentand toeliminateunnecessary ser-
vice 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 theoutdoor 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 t o desired m ode and the User Interface
for automatic control.
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

until the indoor temperature is lowered to the level you have se-

at a time and have shorter “off” periods than on moderate days.
Heating Mode
WiththeUIcontrolset toHEAT,yourunitwill runin heatingmode
until the room temperature is raised to the level you have selected.
Of course, your unit will run for longer periods to maintain a com-

ones.
Supplemental Heat
Your unit is your primary heating source.Yoursystem may also be
equipped with a supplemental heating source such as electric heat.

impede airflow across the coil and reduce the amount of heat ab-

tion, your unit has an automatic defrost mode.
The defrost mode starts at a preset time interval of 30 minutes, al-
though, it may be reset to 60, 90 or 120 minutes. Defrost will start
