Inverter Air-to-Water Heat Pump
Section 4: Installation
Choose a Right Heat Pump Unit
Perform appropriate load calculation to determine required
heating or cooling load for the project. Refer to specifications in
this manual to determine proper size heat pump.
Installation Location
• Units can be installed outdoors as long as the location
determined can handle the weight (see specifications) for
each unit.
• The location is free from heat radiation and other possible fire
hazards.
• 3ft above snow level is required to provide proper condensate
drainage.
• There must be enough space around the unit for maintenance
see "Required Clearances".
Installation Method
The heat pump can be secured onto the concrete pad by
expansion screws, or onto a steel frame with rubber feet which
can be placed on the ground.
Water Loop Connection
Please read below for water piping instructions
• The piping must be clean and free from dirt. Prior to insulating
the pipe, it is suggested that a leak test be performed to ensure
no water leaks are present.
• There must be expansion tank on the top point of the water
loop, and the water level in the tank must be at least 0.5 meter
higher than the top point of the water loop.
• Remove all air from the system prior to powering up. An air
vent is suggested at the highest point in the piping.
• Refer to temperature and pressure guage on unit while unit is
operating to ensure proper operation.
Electrical Connections
• The power supply must go through the wire access and be
connected to the power supply terminals in the control box.
Then connect the 3-signal wire plugs of the wire controller and
main controller.
• External pump can be powered through main power terminals
accessed through main power access on side of the units.
• If an additional auxiliary heater is need to be controlled by the
heat pump controller, the relay (or power) of the aux-heater
must be connected to the relevant output of the controller.
• Power supply for the unit should follow unit electrical
specifications and adhere to local and national electrical codes.
Required Clearances
Inspection before turning unit on
• Check the indoor unit, and make sure that the pipe connections
are secured, leak free and the appropriate valves are open.
• Check the water loop, to ensure that the water inside of the
expansion tank is enough, the water supply is good, the water
loop is full of water/glycol mix* and without any air. Also make
sure there is good insulation for the water pipe.
• Check the electrical wiring. Make sure that the power voltage
is normal, the screws are fastened, the wiring is made in line
with the diagram, and the ground is connected.
• Ensure air to water heat pumps are free of any debris and that
all loose screws or parts have been secured. Once power is
turned on, check controller display for any immediate faults.
A licensed and qualified installer can also verify refrigerant
pressures by using the refrigerant ports located within the unit.
• The flow switch is installed inside of the heat pump, check to
ensure that the wiring and action of the switch is normal and
controlled by the controller.
