regulations may harm the environment and can lead to
the imposition of substantial nes. Should you have any
questions please contact the local oce of the EPA.
If replacing a condensing unit, heat pump or air handler,
the system must be manufacturer approved and Air
Conditioning, Heating and Refrigeration Institute (AHRI)
matched.
NOTICE
Outdoor inverter units are approved for operation above
0°F in cooling mode and -20°F (RH10%) in heating mode
with no additional kit necessary.
Damage resulting from operation of the units in a structure
that is not complete (either as port of new construction or
renovation) is not covered by our warranties.
FEATURES
This heat pump is part of a ComfortBridge™ control system
that uses inverter technology to more eciently control
heat gain/loss with better eciency and achieve targeted
comfort conditions.
The system utilizes digital communication between the
indoor and outdoor equipment and can be controlled by
any single-stage thermostat.
The ComfortBridge control system reduces the number
of required thermostat wires, provides additional setup
features and enhanced diagnostics through Bluetooth
connectivity with the CoolCloud™ app.
Due to components using inverter technology, the heat
pump will not function properly if used with a non-approved
control system.
NOTICE
Special consideration must be given to location of the heat
pump unit(s) in regard to structures, obstructions, other
units, and any/all other factors that may interfere with air
circulation. Where possible, the top of the unit should be
completely unobstructed; however, if vertical conditions
4
require placement beneath an obstruction there should
be a minimum of 60 inches between the top of the unit
and the obstruction(s). The specied dimensions meet
requirements for air circulation only. Consult all appropriate
regulatory codes prior to determining nal clearances.
Another important consideration in selecting a location for
the unit(s) is the angle to obstructions. Either side adjacent
the valves can be placed toward the structure provided the
side away from the structure maintains minimum service
clearance. Corner installations are strongly discouraged.

This unit can be located at ground oor level or on at
roofs. At ground oor level, the unit must be on a solid,
level foundation that will not shift or settle. To reduce the
possibility of sound transmission, the foundation slab
should not be in contact with or be an integral part of the
building foundation. Care should be taken to ensure the
unit is installed away from noise sensitive locations such as
bedrooms, windows and outdoor living areas. Ensure the
foundation is sucient to support the unit. A concrete slab
raised above ground level provides a suitable base.
If it is necessary to install this unit on a roof structure,
ensure the roof structure can support the weight and that
proper consideration is given to the weather-tight integrity
of the roof. Since the unit can vibrate during operation,
sound vibration transmission should be considered when
installing the unit. Vibration absorbing pads or springs can
be installed between the heat pump unit legs or frame and
the roof mounting assembly to reduce noise vibration.
The following elevation minimums are recommended:
Design Temperature Suggested Miminum Elevation
+15° and above 2 1/2"
-5° to + 14° 8"
below -5° 12"
The unit should be well grounded so that potential
eects of electrical noise from the inverter to surrounding
equipment can be minimized.
When selecting an installation location, keep sucient
distance from the heat pump unit and wiring to radios,
personal computers, stereos, etc., as shown in the
following gure.

WARNING
THE COMPRESSOR PVE OIL FOR R-410A UNITS IS EXTREMELY
SUSCEPTIBLE TO MOISTURE ABSORPTION AND COULD CAUSE
COMPRESSOR FAILURE. DONOT LEAVE SYSTEM OPEN TO ATMOSPHERE
ANY LONGER THAN NECESSARY FOR INSTALLATION.
CAUTION
Use only refrigerant grade (dehydrated and sealed) copper
tubing to connect the heat pump unit with the indoor unit.
After cutting the tubing, install plugs to keep refrigerant
tubing clean and dry prior to and during installation. Tubing
should always be cut square keeping ends round and free
from burrs. Clean the tubing to prevent contamination.
The liquid line must be insulated if more than 50 ft. of liquid
line will pass through an area that may reach temperatures
of 30 °F or higher than ambient in cooling mode and/or if
the temperature inside the conditioned space may reach a
temperature lower than ambient in heating mode. Never
attach a liquid line to any uninsulated potion of the suction
line.
Do NOT let refrigerant lines come in direct contact with
plumbing, ductwork, oor joists, wall studs, oors, and
walls. When running refrigerant lines through a foundation
or wall, openings should allow for sound and vibration
absorbing material to be placed or installed between tubing
and foundation. Any gap between foundation or wall and
refrigerant lines should be lled with a pliable silicon-
based caulk, RTV or a vibration damping material. Avoid
suspending refrigerant tubing from joists and studs with
rigid wire or straps that would come in contact with the
tubing. Use an insulated or suspension type hanger. Keep
both lines separate and always insulate the suction line.
Insulation is necessary to prevent condensation from
forming and dropping from the suction line. Armex or
satisfactory equivalent with 3/8” min. wall thickness is
recommended. In severe conditions (hot, high humidity
areas) 1/2” insulation may be required. Insulation must
be installed in a manner which protects tubing and
connections from damage and contamination.
Where possible, drain as much residual compressor oil
from existing systems, lines, and traps; pay close attention
to low areas where oil may collect. NOTE: If changing
refrigerant, the indoor coil and metering device must be
replaced. Only AVPEC air handlers or TXV-V** expansion
valves are compatible and have been manufacturer
approved for use with these models. See unit specications
or AHRI for an approved system match.

If burying refrigerant lines can not be avoided, use the
following checklist:
1. Insulate liquid and suction lines separately.
2. Enclose all underground portions of the refrigerant
lines in waterproof material (conduit or pipe) sealing
the ends where tubing enters/exits the enclosure.
3. If the lines must pass under or through a concrete
slab, ensure lines are adequately protected and
sealed.

IMPORTANT
1. The ends of the refrigerant lines must be cut square,
deburred, cleaned, and be round and free from nicks
or dents. Any other condition increases the chance of
a refrigerant leak.
2. Purge with nitrogen at 2 to 3 psig during brazing
to prevent the formation of copper-oxide inside
the refrigerant lines. The FVC oils used in R-410A
applications will clean any copper-oxide present
from the inside of the refrigerant lines and spread it
throughout the system. This may cause a blockage or
failure of the metering device.
3. After brazing, quench the joints with water or a wet
cloth to prevent overheating of the service valve.
4. A bi-ow lter drier is shipped with the unit as a
separate component and must be brazed on by the
installer on-site. Ensure the bi-ow lter drier paint
nish is intact after brazing. If the paint of the steel
lter drier has been burned or chipped, repaint or treat
with a rust preventative.
The recommended location of the lter drier is before the
expansion device at the indoor unit.
Do NOT make nal refrigerant line connection until plugs
are removed from refrigerant tubing.
WARNING
WARNING
Using dry nitrogen, pressurize the system to 450 PSIG.
Allow the pressure to stabilize and hold for 15 minutes
(minimum). If the pressure does not drop below 450 PSIG
the system is considered leak free. Proceed to system
evacuation using the Deep Vacuum Method. If after 15
minutes the pressure drops below 450 PSIG follow the
procedure outlined below to identify system leaks. Repeat
the Standing Pressure Test.
WARNING
WARNING
Leak test the system using dry nitrogen and soapy
water to identify leaks. If you prefer to use an electronic
leak detector, charge the system to 10 PSIG with the
appropriate system refrigerant (see Serial Data Plate
for refrigerant identication). Do not use an alternative
refrigerant. Using dry nitrogen nish charging the system
to 450 PSIG. Apply the leak detector to all suspect areas.
When leaks are discovered, repair the leaks, and repeat
the pressure test. If leaks have been eliminated proceed to
system evacuation.
Condensing unit liquid and suction valves are closed to
contain the charge within the unit. The unit is shipped with
the valve stems closed and caps installed. Do not open
valves until the system is evacuated.

WARNING
CAUTION
The Deep Vacuum Method requires a vacuum pump
rated for 500 microns or less. This method is an eective
and ecient way of assuring the system is free of non-
condensable air and moisture. As an alternative, the Triple
Evacuation Method is detailed in the Service Manual for
this product model.
It is recommended to remove the Schrader Cores from the
service valves using a core-removal tool to expedite the
evacuation procedure.
1. Connect the vacuum pump, micron gauge, and
vacuum rated hoses to both service valves.
Evacuation must use both service valves to eliminate
system mechanical seals.
2. Evacuate the system to less than 500 microns.
3. Isolate the pump from the system and hold vacuum
for 10 minutes (minimum). Typically, pressure will rise
slowly during this period. If the pressure rises to less
than 1000 microns and remains steady, the system is
considered leak-free; proceed to system charging and
startup.
4. If pressure rises above 1000 microns but holds steady
below 2000 microns, non-condensable air or moisture
may remain or a small leak is present. Return to step
2: If the same result is achieved check for leaks and
repair. Repeat the evacuation procedure.
5. If pressure rises above 2000 microns, a leak is
present. Check for leaks and repair. Repeat the
evacuation procedure.

Inverter units are accessed the compressor lockout by any
of the following methods:
• setting the “Cbp” menu (Compressor lockout
temperature) to through the indoor unit control board
push buttons
• Through the CoolCloud HVAC phone application
If installing with a CTK04 thermostat, please see the
addendum for further instructions.
BOOST MODE can be enabled or disabled through the
control board push buttons or through the CoolCloud app.
BOOST MODE allows the system to operate at increased
compressor speed to satisfy unusually high loads. BOOST
MODE is initiated by an outdoor temperature sensor
located in the outdoor unit.
Please note that outdoor equipment operational sound
levels may increase while the equipment is running in
BOOST MODE. Disabling BOOST MODE will provide the
quietest and most ecient operation.
BOOST MODE is ON by default and is activated when the
outdoor temperature reaches 105°F. BOOST MODE can
be disabled and enabled and the activation temperature
adjusted in the Settings menu of the CoolCloud app or
through the indoor / outdoor push button menus.
If installing with a CTK04 thermostat, please see the
addendum for further instructions.
Dehumidication requires a thermostat capable of reading
the indoor humidity level and allowing the user to set a
dehumidication target.
The thermostat controls the humidity level of
the conditioned space using the cooling system.
Dehumidication is engaged whenever a cooling demand
is present and humidity levels are above the target level.
When this condition exists, the circulating fan output is
reduced, increasing system run time, over cooling the
evaporator coil and ultimately removing more humidity from
the structure than if only in cooling mode.
The thermostat may also allow for an additional
overcooling limit setting depending on the thermostat
utilized. This allows the cooling system to further reduce
humidity by lowering the temperature below the cooling
setpoint in an attempt to better achieve desired humidity
levels.
For eective dehumidication operation:
• Ensure “Dehumidication selection” is NOT set to
“OFF”.
• Verify the cooling airow prole is set to “Prole D”.
- See the Cool Set-up section of the Installation Manual for
complete airow prole details.
- By default, “Dehumidication selection” is standard and
the cooling airow prole is set to “Prole D”.
• For additional dehumidication control, airow settings
are eld adjustable and can be ne-tuned to a value
that is comfortable for the application from a range of
Cool Airow Trim.
• In addition, the system can have Enhanced
Dehumidication operation in setting “A”, “B”,
or “C” of “Dehumidication Selection” based on
dehumidication demand.
- See the DEHUMIDIFICATION SELECT section of the
Installation Manual for more detail.
The ComfortBridge based inverter heating and air
conditioning system uses an indoor unit and outdoor unit
digitally communicating with one another via a two-way
communications path. ComfortBridge is compatible with
any 24 VAC single stage thermostat which send inputs to
the indoor unit.
The ComfortBridge system permits access to system
information, advanced set-up features, and advanced
diagnostic/troubleshooting features via the control board
push buttons or the CoolCloud HVAC app.

(If using a CTK04 thermostat, please see the addendum
for further instructions.)
The heat pump’s diagnostics menu provides access to the
most recent faults. The six most recent faults can be
accessed through the control board seven segment
displays or the CoolCloud mobile app. Any consecutively
repeated fault is stored a maximum of three times.
Example: A leak in the system, low refrigerant charge or an
incompletely open stop valve can cause the unit to ash
error code E15. This error code suggests that the unit is
experiencing operation at low pressure. The control will
only store this fault the rst three consecutive times the
fault occurs.
This menu displays information about the systems current
status. This menu can be utilized to conrm correct
functionality of the equipment and for troubleshooting
purposes.
The following items will be displayed:
• Heat Capacity Request Percentage
• Cool Capacity Request Percentage
• Heat Capacity Request During Defrost Percentage
• Dehumidication Request Percentage
• Reversing Valve Status
• Reported Airow by Indoor Unit
• Boost Mode
• Previous Defrost Run Time
The following sensor values will be displayed:
• Outdoor Temperature
• Coil Temperature
• Liquid Line Temperature
• Discharge Temperature
• Defrost Sensor
• Suction Pressure
This function can be enabled in this menu.
The mandatory system verication test is enabled from this
menu, which enables a functional check of the equipment,
in addition to ensuring proper stop valve position.
The system allows for the adjustment of several cooling
performance variables. Cool Airow Trim (*1), Cool Airow
Proles, Cool Fan ON Delay, Cool Fan OFF Delay and
Dehumidication Select (some enable option or o) can
be adjusted in this menu. You can also reset this entire
menu to factory default settings. See the following images

3. The Inverter system uses lower compressor speed
and lower indoor unit CFM to optimize system
performance. To obtain 100% CFM for home
circulation, use full Trim setting instead of Int/
Low speed. This is recommended for applications
with unusually cold return temperatures such as
basements.
Dehumidication requires a thermostat capable of reading the
indoor humidity level from the thermostat and allows the user
to set a dehumidication target based on these settings.
The thermostat controls the humidity level of the conditioned
space using the cooling system. Dehumidication is
engaged whenever a cooling demand is present and
structural humidity levels are above the target level. When
this condition exists, the circulating fan output is reduced,
increasing the system run over time, over cooling the
evaporator coil and ultimately removing more humidity from
the structure than if only in cooling mode.
The thermostat may also allow for an additional overcooling
limit setting depending on the thermostat utilized. This allows
the cooling system to further reduce humidity by lowering
the temperature below the cooling setpoint in an attempt to
better achieve desired humidity levels.
When Dehumidication mode exists, the circulating fan
output is reduced, increasing system run time, over cooling
the evaporator coil and ultimately removing more humidity
from the structure than if only in cooling mode.
The system can have Dehumidication operation in setting
“Standard”, “A”, “B” or “C” of “dehumidify with cooling”
menu based on dehumidication demand.
Setting “Standard” allows for the widest compressor
operation range with lower CFM than Cooling mode.
In the Enhanced Dehumidication (setting A, B and C)
the indoor airow is lower than Standard Dehumidication
(Standard).
Setting “A” allows for the same compressor operation
range as standard Dehumidication with lower CFM than
standard dehumidication (Standard).
Setting “B” limits compressor operation range and keeps
high dehumidication capacity.
In setting “C” the system runs xed at 100% compressor
and airow. See Figure 1.
Max compressor speed at which the outdoor unit will
operate can be changed through the control board seven
segment displays or the CoolCloud mobile app.
Max compressor speed can be changed to get the required
capacity or eciency.
Once the maximum speed is set, the system operates
between the set maximum speed and default low speed.
When determining the appropriate compressor speed
for cooling and heating, in the “RPS Range For Cooling/
Heating” menu select the range that contains the desired
value.
(Then, after pressing the Apply Changes button, leave the
Device setting menu and enter the this menu again.
Otherwise, the changed settings will not be reected.)
Next, in the “Selected RPS for Cooling/Heating” menu,
select the desired RPS within the displayed range.
