2.10 Trial run
Checking list before trial- running:
Correct installation of the system.
Correct connection of water/air piping and wiring.
Condensate draining smoothly well insulation work for all hydraulic part.
No obstacle outside the air inlet and outlet.
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 atm ~ 6,4 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 but 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
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.
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.
Note:
In the E-heat mode, only half tank of water, i.e. 150L, could be heat every time.
How is the unit running?
If unit is OFF, press
and the unit will be waken, then press to set target water
temperature(38
~
60
℃
),press and the unit will automatically select mode and start to
heat water to target temperature.
Note:
If system occurs some malfunctions, error code E7 and
will be shown on the display,
then heat pump will stop running and the unit will activate automatically E-heater as the
backup heat source, but the code E7 and
will be shown until power off.
