RC3/4". It is used to prevent water from flowing backwards.
The drainage pipe should be insulated to prevent water inside pipe from freezing in cold
weather.
Do not dismantle the PT Valve, and do not block off the drainage pipe.
After water system piping connection, turn on the inlet and outlet valve to effuse the tank.
When water flow smoothly out from outlet pipe, the tank is full, turn off all valves to check
the pipeline leakage.
If the inlet water pressure is less than 0.15MPa (1,5atm), a pump should be installed at
the water inlet. If the water supply hydraulic is higher than 0.65MPa (6,5atm), a reducing
valve should be installed at the water inlet pipe.
Condensate may be leaked from unit if drainage pipe is blocked, so a drainage pan should
be installed.

2.9 Water affusion and effusion
Water affusion: If the unit is used for the first time or used again after emptying the tank, please
make sure that the tank is full of water before turning on the power.
1) Open the cool water inlet valve and the hot water outlet valve.
2) When water flows out from the water outlet, the tank is full. Turn off the hot water outlet
valve and water affusion is finished.
Caution:
Operation without water in water tank may result in the damage of auxiliary E-heater.
Due to such damage, manufacturer will not be liable for any damages caused by this issue.
Water effusion: If the unit needs cleaning, moving etc, the tank should be emptied.
1) witch off the unit, and close the cool water inlet valve, open the hot water outlet valve and
open drainpipe.
2) After emptying, the nut of drainpipe should be replaced and closed.
Note: The outlet water temperature maybe very high when emptying, beware of your body for burns.

2.10 Trial run
Checking list before trial- running:
Correct installation of the system.
Correct connection of water piping and wiring.
Correct connection of air inlet and outlet.
Condensate draining smoothly well.
All the insulation work for all hydraulic part.
Correct power supply.
No air in the water pipeline and all valves opened.
Effective electric leakage protector installation.
Sufficient inlet water pressure, between 0.15MPa and 0.65Mpa (1,5 ~ 6,5 atm).
Water temperature display
The temperature shown of the display depends on the upper sensor.
It is normal that the display temperature has reached to target temperature.
Compressor still running, because the lower water temperature does not get to target
temperature.
Heat source shift
The default heating source is heat pump. If the ambient is range out of heat pump, heat
pump will stop running, and the unit will shift automatically to activate E-heater and show
the icon ‘ LA ’ on the display, then if the ambient temperature goes into the running range of
heat pump again, it will stop E-heater and shift automatically to heat pump again, and the
icon ‘ LA ’ will be extinguished.
E-heater will be activated once for the current heating progress, if want to apply E-heater
again, the button of ‘ E-HEATER ’ should be pressed once.
If the target setting water temperature is higher than the maximum temperature (Heat
pump), the unit will activate heat pump firstly to the maximum temperature, then stop heat
pump, activate E-heater to continually heat water to the target temperature.
If manually activate the E-heater running mode when heat pump running, E-heater and heat
pump will work together until the water temperature gets to target temperature. So if want to
heat quickly, E-heater should be activated manually.
