3. Safety Instructions
· Installation, repairs and maintenance of this unit must be performed by a qualified technician. · Any wiring must comply with local electrical regulations. · If any abnormal instances occur or a strange smells, the unit must be shut off by the power supply. · Do not put fingers or objects into the fans or evaporator of the unit. · The unit must be earthed to avoid any risk caused by insulation defects. · No wiring must come into contact with the heat source or the rotating fan parts. · The unit must be handled and lifted with appropriate equipment in correlation with the unit's size and weight. · Electrical power must be switched off before any work is started on the unit. · Do not expose the unit to or install near any flammable gases. · Ensure there is a circuit breaker for this unit. · Copper and iron can not be used as a fuse. · The unit is equipped with an over-load protection system. After a previous stoppage, the unit will not start for at
least 3 minutes. · If the supply cord is damaged, it must be replaced by the manufacturer, our service agent or a similarly qualified
person in order to avoid a hazard. · USE SUPPLY WIRES SUITABLE FOR 75. · Caution: Single wall heat exchanger, not suitable for potable water connection.
4. Installation
4.1 Transit
When the heat pump is to be transported, please keep the unit standing upright. The unit cannot be laid down, otherwise inner parts of the device may become damaged. If the unit needs to be hung up during installation. Use the special lifting hole (hook) on the unit base), an 8 metre cable will be needed to do so. There must be padding of some kind between the cable and the unit to prevent damage to the heat pump cabinet. DO NOT TOUCH THE RADIATING FINS BEHIND THE MACHINE WITH HANDS OR OBJECTS!

5 Evo Max Series Manual

4.2 Location of Install & Minimum Clearances
The unit can be installed in any outdoor area which can carry 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 Plumbing Component
· 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.
· The connection between the heat pump and the construction is best to be of a flexible type to avoid vibration transfer. The support to the water pipe must be separate, but not rely on the heat pump unit.
· 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.
4.4 Electrical Component
- 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.
ATTN: - The unit should use an independent power supply, see wiring as required in the below table. Power supply
voltage must be in line with the rated voltage.
- The power supply circuit must be equipped with an All-pole disconnect device and have at least 3mm contact opening distance.
- The wiring must be completed by a professional technician in accordance with the circuit diagram.
- Power supply circuit must have earth wire; the earth wire of power should be connected with an external earth wire safely. The external earth wire must be in order.
- The creepage protection device must be settled in accordance with the relevant national technical standards for electronic equipment.
- The power wire and signal wire should be neatly arranged. High voltage wires and low voltage wires must be separated and free from any interference. These wires must also be free from any pipes or valves on the unit.
- When all wiring is completed, the power should only be connected after a thorough double check.

4.5 Initial Start-up of the Unit
Prior to Trial Operation
Check the indoor unit, make sure that the pipe connection is done correctly and that the relevant valves are open.
Check the water loop to ensure that there is enough water inside of the expansion tank, that the water supply is good and that the water loop has no air in it and is full of water. Make sure there in 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 earthing is connected.
Check that the heat pump, including all the screws and different parts are in good order. When the power is on, review the indicator on the controller to see if there is any failure indications. The gas gauge can be connected to the check valve to see the high pressure (or low pressure) of the system during trial running.
Trial Operation Start the heat pump and check whether the water pump is running, if it is running normally there will be 0.2MPa on the water pressure meter.
When the water pump runs for 1 minute, the compressor will start. Hear whether there is a strange sound coming from the compressor. If an abnormal sound occurs, please stop the unit and check the compressor. If the compressor runs well, look for the pressure meter of the refrigerant.
Check whether the power input and running current is in line with the manual. If not stop the unit and check for why this may be occurring.
Adjust the valves on the water loop to make sure that the hot (cool) water supply to each door is good and meets the requirement of heating (or cooling).
Review whether the outlet water temperature is stable.

8. Maintenance
Check the water supply and the air vent frequently to avoid lack of water or air in the water loop.
Clean the water filter periodically to keep the water good quality. Lack of water and dirty water can damage the unit. The heat pump will start the water every 72 hours when it is not running to avoid freezing.
Keep the unit in a clean, dry place with good ventilation. Clean the heat exchanger every few months to keep a good heat exchange rate and save energy.
Check each part of the unit and the pressure of the system. Replace any failing parts and recharge the refrigerant if needed.
Check the power supply and the electrical system, make sure all electrical components are wired well and working.
If the heat pump is not to be used for an extended period of time, please drain all the water out.
Drain the water out from the lowest point of the heat exchanger to avoid freezing in winter. Water recharge and full inspection on the heat pump is needed before being restarted.
The water loop of the heat pump MUST be protected from freezing in winter. Do not shut off the power supply to the heat pump in winter. When the air temperature is below 0°C, if the inlet water temperature is above 2°C and below 4°C the water pump will begin freezing protection. If the inlet water is lower than 2°C, the heat pump will begin heating.
