Appendix

Install Sketch Map

Note:

1. The Factory only offers the main unit in the legend, the other modules which are indispensable fittings are to be provided by the user or installation company.
2. The unit of which code contains the letter “B” has a water pump inside and an external water pump is not needed.
3. Automatic ventilation (15) is installed on the top point of the water system.
4. The quantity proportion of the two-way valve (13) and the three-way valve (14) is referred to the technical regulation, and there is a three-way valve installed on the farthest place of water system.
5. The ball valve (17) is used when it is swashed, and the water in the water system is filled.

Automatic Filled Water Valve

1. When the automatic filled-water valve is installed, the arrowhead orientation of inlet water must accord with the orientation of the valve
2. Automatically filled water has been adjusted in advance to 1.5bar
3. If readjusting the pressure of inlet water, operate as follows:
   • a. Open the screw cap (C)
   • b. If reducing the pressure of water supply, screw down the pressure to adjust the screw (B)
   • c. If increasing the pressure of water supply, screw down the pressure to adjust the screw (B)
4. When the system needs the water filled first, rest the handle (A) of the filled water. Then the handle (A) can return (close) when the system is full of water.
5. The automatic filled-water valve needs cleaning at a periodic time and then you must close the tap, unscrew the plug (D), and remove the inside filter net. Reassemble them again after cleaning.
   • NOTE: There are two connections for the water pressure meter in the central section of automatically filled water, where the water pressure meter can be connected directly and display the set pressure. The screw cap ( C ) must be tweaked after adjusting the filled water pressure.

Leakage Pressure Valve

1. The action pressure of the leakage pressure valve is more than 3 bar (the valve is open) but the pressure cannot be adjusted.
2. The valve will open automatically to make sure that the water loop of the air-con system is safe when the water pressure in the backwater side is higher than the set pressure.

Maintenance

F.A.Q

• 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 has 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 the system, as this will influence the unit’s performance and reliability.
  • The area around the unit should be dry, clean, and well-ventilated. Make sure nothing is 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.
  • 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.
• WHAT SHOULD I BE CHECKING REGULARLY?
  • 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.
