Page | 12

4.2 Choosing the Right Unit

Based on the local climate conditions, construction features and insulation level, calculate the required

cooling (heating) capacity per square meter.

Conclude the total capacity which will be needed by the construction.

According to the total capacity needed, choose the right model by consulting the heat pump features as

below:

Heat Pump Features

Cooling Only Unit: chilled water outlet temp. at 5-15°C, maximum ambient temp. at 43°C

Heating and Cooling Unit: for cooling chilled water outlet temp. at 5-15°C, maximum ambient temp. at 43°C.

For heating warm water inlet temp. at 40-50°C, minimum ambient temp. at -10°C.

Unit Application

The Evo Flex can be installed in houses, offices, hotels and many more locations which require heating and

cooling separating, with each area needing to be controlled independently.

4.3 Installation Location

• The unit can be installed in any place outdoors which will be able to support the weight of a heavy

unit such as a terrace, roof, the ground and any other places deemed suitable.

• The location must have good ventilation.

• The location must be free from heat radiation and other fire hazards.

• A pall is needed in winter to protect the unit from snow.

• There must be no obstacles near the inlet and outlet of the unit.

• The installation location must be protected from strong winds or air.

• There must be a water channel around the heat pump to drain condensing water.

• Leave enough space around the unit for maintenance.

Page | 13

4.4 Installation Method

The heat pump can be installed onto the concrete basement by using expansion screws, or onto a steel

frame with rubber feet which can be placed on the ground or the roof. Ensure that the unit is placed

horizontally.

4.5 Water Loop Connection

Please pay attention to the below matters when the water pipe is connected.

• 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.

4.6 Power Supply Connection

• Open the front panel and open the power supply access.

• The power supply must go through the wire access and be connected to the power supply terminals

in the controlling box. Then connect the 3-signal wire plugs of the wire controller and main

controller.

• If an external water pump is required, please insert the power supply wire into the wire access and

connect it to the water pump terminals.

• If an additional auxiliary heater is needed 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.

Page | 14

4.7 Transit

If the unit needs to be hung up during installation, an 8-metre cable is

required. There must be a soft material between the cable and the unit to

prevent damage to the heat pump cabinet (see picture 1).

WARNING

DO NOT touch the heat exchanger of the heat pump with fingers or other

objects!

4.8 Inspection Before Trial Running

Inspection before trial running

• Check the indoor unit, make sure that the pipe connection is done correctly, and the relevant valves are

open.

• Check the water loop to ensure that the water inside of the expansion tank is filled to an appropriate

level, and the water supply is working, and the water loop is full of water and free of trapped air. 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 that the earthing is connected.

• Check that the heat pump includes all the screws and components, and that they are in good order.

When powering the unit on, review the indicator on the controller to see if there is any indication of

failure. The gas gauge can be connected to the check valve to see the high pressure (or low pressure) of

the system during trial running.

4.9 Trial Running

• Start the heat pump by pressing the ‘POWER’ button key on the controller. Check whether the water

pump is running, if it runs normally there will be 0.2MPa on the water pressure meter.

• When the water pump has ran for a minute, the compressor will start. Listen for any strange sounds

from the compressor, if an abnormal sound occurs please stop the unit and check the compressor. If the

compressor runs well please look for the pressure meter of the refrigerant.

• Check whether the power input and running current is in line with the manual. If not please stop and

check.

• Adjust the valved on the water loop to make sure that the hot (cool) water supply to each door is good

and meets the requirements of heating (or cooling).

• Review whether the outlet water temperature is stable.

• The parameters of the controller are set by the factory, the user cannot change these themselves.
