4. Installation
4.1 Transit
When transporting the unit, ensure the unit is kept standing upright. Laying the unit down may damage internal parts.
If the unit needs to be hung up (such as for lifting with a crane) use an 8 metre cable. Ensure there is some kind of
padding between the cable and the unit to prevent damage to the heat pump cabinet.
4.2 Location of Install
The unit can be installed in any outdoor area which can carry the weight of heavy machinery, such as a terrace,
rooftop, the ground etc.
•
The location must have adequate ventilation and be free from strong winds.
•
The installation location must be free from heat radiation and fire hazards.
•
Ensure there are no obstacles near the air inlet and outlet of the heat pump.
•
There must be a water channel around the heat pump to drain condensing water.
•
Ensure that there is enough space around the unit for maintenance.
•
The heat pump can be installed onto the concrete basement using expansion screws, or onto a steel frame
with rubber feet which can be placed on the ground or rooftop. Ensure the unit is placed horizontally.
4.3 Minimum Clearances
A:
500mm
B:
1500mm
C:
1000mm
D:
500mm
4.4 Plumbing
•
Try to reduce the resistance to the water from the piping.
•
The piping must be clear and free from dirt and blockage. A water leakage test must be carried out to ensure that
there is no water leaking before the installation can be made.
•
The pipe must be tested by pressure separately. DO NOT test it together with the unit.
•
There must be an expansion tank on the top point of the water loop, and the water level inside the tank must be at
least 0.5meters higher than the top point of the water loop.
•
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.
•
Try to avoid any air from being trapped inside the water pipe, there must be an air vent on the top point of the
water loop.
•
There must be a thermometer and pressure meter at the water inlet and outlet for easy inspection during running.
•
There must be drainage on the low points of the water system, and there is already drainage on the chassis of the
heat pump. The water in the system must be drained out during winter if the heat pump is not to be used.
4.5 Electrical Connection
•
Open the panel and open the power line hole
•
Thread the power line though the hole and connect it to the power line terminal. The three-core control line of the
remote controller shall be plugged with the three-core signal line on the main board according to the wiring
diagram.
•
For an external water pump, thread the power line of the water pump through the hole and connect it to the water
pump terminals.
•
If an additional auxiliary heater is needed to be to be controlled by the heat pump controller, the relay (or power) of
the aux-heather must be connected to the relevant output of the controller.
