Installation

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 the special lifting hole (hook) on the base of the unit with 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.

Location of Installation
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.

Airflow Clearances

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.
• 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.

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.

ATTENTION:

• The unit should use an independent power supply, see wiring in 8.4 Cable Specifications. 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.

Initial Start-Up

Prior To:

• 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.

Maintenance

DO I NEED TO GET MY UNIT SERVICED?
It is recommended that you get your EvoHeat unit serviced once a year by your local certified air conditioning or refrigeration technician. If your unit is located in a coastal area, more frequent maintenance may be necessary. During the service, they will check the operational pressures of the refrigeration system and give the unit and fins a good clean to ensure maximum performance.

DO WE HAVE RECOMMENDED SERVICE AGENTS?
EvoHeat have a large database of recommended service agents. Please contact EvoHeat tech support on 1300 859 933 for your local service agent details.

SHOULD I CHECK MY UNIT REGULARLY?
We recommend you check your unit regularly to avoid potential issues and damage to your heat pump.
Check the water inlet/outlets often for leaks. You should avoid the condition of no water or air entering into the system, as this will influence unit’s performance and reliability.
The area around the unit should be dry, clean and well ventilated. Make sure there is nothing blocking the airflow of the heater e.g. Leaf litter. Clean the heat exchanger every few months to keep a good heat exchange rate and save energy.

WHAT SHOULD I BE CHECKING REGULARLY?

You should discharge the water at the bottom of the water pump if the unit will not be used for an extended period. Discharge all water in the water pump and water system so that freezing of the water in the pump or water system does not occur. Check the unit thoroughly and fill the system with water fully before using it for the first time after a period of time.

Check the power supply and cable connection often, should the unit begin to operate abnormally, switch it off and contact the qualified technician
Clean the water filter periodically to maintain good water 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.

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.
