BASIC OPERATION PRINCIPLE

As we know with our experience, the natural flow of heat, which moves from a higher to a lower temperature source. the heat pump can transfer heat from a lower temperature source to a higher temperature source with high efficiency.

The advantage of a heat pump water heater is that it can supply more heat energy, normally 3 times than input electricity power by extracting the heat from ambient atmosphere in a free charge way to Sanitary Hot Water, compare to the traditional water heater, such as electric water heater or gas burner water heater, their efficiency is normally less than 1, which means it will dramatically cut off the bill of family daily SHW by the application of heat pump water heater, following data will show more details.

Power consumption comparison under the same condition to heat 1 ton water from 15°C to 55°C

3.5 Cold water connection
Before connection check that the piping is clean without any particles from installation. The installation has to include a new safety valve set to 7 bar ( 0,75 MPa ), compliant to EN 1487 and connected directly on the cold water inlet.
No hydraulic device (stop valve, pressure reduction, flexible…) is allowed between the safety valve and the cold water inlet of the water heater.
As water can flow from the safety valve the drain should be kept in open air. In any type of installation there should be a cold water stop valve, before the safety valve. The overflow of the safety valve has to be connected to the used water evacuation through a siphon. Installation has to be in a frost-free environment. The safety valve has to be operated regularly to check the working condition (1 – 2 times per month). The installation should be equipped with a pressure reduction if the main water supply pressure is higher than 5 bar (0,5 MPa). The pressure reducing device has to be installed at the beginning of the distribution network (before the safety valve). We recommend a supply pressure of 3 – 4 bar (0,3 to 0,4 MPa. The appliance cannot connected by a hose-set.

3.6 Hot water connection
Do not connect copper tubes directly on the tank connection. You have to fit the supplied insulation union (not included in the supply). In case that the tank connection is corroded without this protection the warranty will not apply.
If the installation is made with synthetic pipes (e.g. : PER, multi-layer…), install mandatory a thermostatic control valve at the connection pipes of the water heater. The setting should be done in relation with the specification of the installed piping.
3.7 Condensate evacuation
The temperature drop of the air passing through the exchanger forms condensation from humidity in the air. The condensed water is evacuated on the rear of the tank using the supplied plastic tube.

4. Heat Source Shift
   The default heating source is heat pump. If ambient is range out of heat pump, heat pump will stop running, the unit will shift automatically to activate E-heater, 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.
   If the target setting water temperature is higher than Max. temp(Heat pump), the unit will activate heat pump firstly to the Max. temperature, then stop heat pump, activate E-heater to continually heat water to the target temperature.
   If manually activate the E-heater running 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, please manually activate E-heater.
   NOTE
   E-heater will be activated once for the current heating progress, if want to apply E-heater again, plsease push again.
   If system occurs some malfunctions, error code “EHHP” 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 “EHHP” and will be shown until power off.
   Defrosting During Water-heating In heat pump running period, if the evaporator frosted in lower ambient temperature, the system will defrost automatically to keep effective performance(about 3~10min). At defrosting time(when the ambient temperature is below 5°C), the fan motor will stop, but compressor will still run.
   Heat-up Time There are different heat-up times in different ambient temperature. Normally lower ambient temperature result longer heat-up time because of lower effective performance. In the ECO mode, the heating time of the water temperature is 9-55°C,please refer to Table.4-3.Time difference may occur due to different installation scenarios. This is normal.

TROUBLE SHOOTING

6.1 Non-error tips
Q: Why compressor can’t start immediately after setting? A: Unit will wait for 3 min to balance the pressure of system before
start compressor again, it’s a self protection logic of unit.
Q: Why sometimes the temperature shown on the display panel decreased while unit is running?
A: When the upper tank temperature is much higher than the bottom part, upper part hot water will be mixed by the bottom cold water which is continually flow from inlet tap water so that will decrease the upper part temperature.
Q:Why sometimes the temperature shown on the display decreased but unit still keep closed?
A: to avoid unit ON/OFF frequently, unit will activate heat source only when bottom tank temperature is lower than setting temperature.
Q:Why sometimes the temperature shown on the display will decreased dramatically?
A: Because tank is pressure-bearable type, if there is massive hot demand, hot water will quickly tapped out from upper part of tank as well as cold water will quickly tapped into bottom part of tank, if the cold water surface emerge the upper temperature sensor, temperature shown on the display will decreased dramatically.
Q:Why sometimes the temperature shown on the display is decreased a lot, but there is still a mount of hot water can be tapped?
A:Because the upper water sensor is located on the upper 1/4 tank, when tapping hot water out, it means there is at least 1/4 tank of hot water available.
Q:Why sometimes unit shows “EHLA” on display ? A: When the unit does not have electric heating function, the heat pump available running ambient air inlet range is -7-43°C,if ambient air inlet temperature is out of range, system will show above-mentioned signal to let user notice it.
Q: Why sometimes the buttons are unavailable? A: if there is no operation on panel for 60s, unit will lock the panel,
shows ” “, to unlock the panel, please press the ” “+ ” “button for 2 seconds.
Q: Why sometimes there is some water flowed from drainage pipe of safety valve?
A: Because the tank is pressure-bearable one, when water is heated inside the tank, water will expand, so the pressure inside of tank will increase, if pressure goes up more than 1.0Mpa, safety valve
will activate to relief the pressure and hot water drop will be discharged correspondingly. If water drop is continually discharged from safety valve drainage pipe, it is abnormal, please contact qualified stuff to repair.
