Final Installation Checklist
Final Installation Checklist
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 filter, 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.
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.
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.

Unit 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 protected with a low pressure switch. The feedback
will prevent the compressor from operating at low suction
temperatures.
Heat Pump Operation
The unit is designed to operate heat pump as the primary
source of heating without a cutoff temperture. The cutoff
temperature can be set at the thermostat ,depeding on
the type of thermostat used. The unit will operate as heat
pump until the thermostat sends an emergency heat (W2)
signal to the equipment.
Defrost Mode
When the outdoor coil accumulates enough frost, the
unit will cycle through a defrost mode, during which
the compressor and partial electric heat will operate
concurrently so that the conditioned space is not
compromised. Once the outdoor coil rises above 60F, the
unit will resume its normal operation.
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.
