Initial Start-Up

Pre-Inspection

  • 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.

Trial Running

  • Start the heat pump by pressing the ‘POWER’ button 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, 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 and check.
  • Adjust the valves 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 must change these themselves.

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.
