accessories have been installed properly and
that they have not been damaged during the
installation process.
 Ensure that all installation instructions
concerning clearances around the unit have
been adhered to.
 Check to ensure that the unit air filter, indoor

obstructions.
 Ensure that the circuit breaker(s) or fuse(s)
and supply circuit wire size have been sized
correctly.
 Check the condensate water drain(s) to
ensure that they are adequate for the
removal of condensate water and that they
meet approval of the end user.
 Ensure that the entire installation is in
compliance with all applicable national and
local codes and ordinances having
jurisdiction.
 Secure all access panels (i.e. front cover
and/or control box), apply power to the unit
 The unit commissioning should be done at
this time to ensure unit function.
NOTE: Maintaining a log for recording the dates
of maintenance and/or service is recommended,
and should be suggested to the owner or
operator of the equipment.

Chassis Operation
Cooling Operation
The set point must be at least 3°F below room
temperature to ensure compressor operation.
In the cooling mode, when demand is present, the
indoor blower and outdoor fan will operate. The
compressor will vary operating speed to maintain
desired set point.
Heat Pump Operation
The set point must be greater than 3°F but not
greater than 6°F above room temperature to ensure
compressor operation.
In the heating mode, when demand is present, the
indoor blower and outdoor fan will operate. The
compressor will vary operating speed to maintain
desired set point.
Electric Heat Operation
If the set-point is greater than 6°F above room
temperature, the heat pump operation will be
terminated and the electric heater will be energized
to satisfy the heating demand.
If heat pump operation is not available due to
defrost or error, the electric heater will be used to
satisfy heating demand.
FreshAire™
The FreshAire™ System (optional) delivers outside
air to the indoor space. The module has a fan that
draws outdoor air into the module. The outdoor air
leaves the module through a filter and enters the
indoor space in front of the indoor conditioning coil.
The outdoor air mixes with the return air and is
drawn through the indoor conditioning coil. The
optional module can be configured as either a single
(F option) or a dual (D option)..
Inspect and ensure that all components and
accessories have been installed properly and
that they have not been damaged during the
installation process.
Ensure that all installation instructions
concerning clearances around the unit have been
adhered to.
Check to ensure that the unit air lter, indoor
coil, and outdoor coil are free from any
obstructions.
Ensure that the circuit breaker(s) or fuse(s) and
supply circuit wire size have been sized correctly.
Check the condensate water drain(s) to ensure
that they are adequate for the removal of
condensate water and that they meet approval of
the end user.
Ensure that the entire installation is in
compliance with all applicable national and local
codes and ordinances having jurisdiction.
ENSURE THAT THE SUPPLY VOLTAGE TO THE
UNIT IS WITHIN THE OPERATING RANGE
Secure all access panels (i.e. front cover and/or
control box), apply power to the unit.
The unit commissioning should be done at this
time to ensure unit function.
NOTE: Maintaining a log for recording the dates
of maintenance and/or service is recommended,
and should be suggested to the owner or
operator of the equipment.
Present the owner or operator of the equipment
with the Installation & Operation Manual, all
accessory installation instructions, and the name,
address and telephone number of the Authorized
Friedrich Warranty Service Company in the area
for future reference if necessary.
NOTE: The unit is not designed to guarantee
continuous operation with outdoor ambient
conditions greater than 115F.

Chassis Operation
Fresh Air Door
The fresh air door is an “intake” system. It is
opened via a slide mechanism on the front of the
chassis located just above the indoor coil. Move
the slide left to open and right to close the door.
The system is capable of delivering up to 60 CFM of
outdoor air.
Low Ambient Compressor Cut Out
Each chassis is equipped with low ambient
protection that is determined by thermistor
feedback. The feedback will prevent the
compressor from operating at low suction
temperatures.
Room Freeze Protection
This feature will monitor the indoor room
conditions and in the event that the room falls
below 40F, the unit will cycle on high fan with the
electric heater. This occurs regardless of mode.
This equipment is not intended for use during
construction. The use of equipment during con-
struction could result in premature failure of the
components and/or system and is in violation of
our standard warranty guidelines and may result
in the suspension or termination of the warranty.
