1. Features
² Safety:
1. Complete isolation between water and electricity without electric shock problem, more safety.
2. No fuel tubes and storage, no potential danger from oil leakage, fire, explosion, and so on.
3. No cross contamination potential, the condenser coil is wrapped around the enameled inner tank.
² The maximum outlet water temperature: 70°C. The system makes the water be heated stably and
quickly with innovative heating methods of combination the electric heating and heat pump heating
properly.
² Flexible installation achieves by long air inlet and outlet duct with pressure. 25Pa air flow pressure
enables ducted length up to 10 meters.
Note: A≤10m or A+B≤10m
² Automatic startup and shutdown, automatic defrosting by revising refrigerant cycle to save the extra
operation.
² According to the heat pump principle, the unit absorbs heat from outdoor air and produce heat water;
thermal efficiency can be up to 3.8(Under the condition A15/12 W15/45).
² CE and NF certification.
² Within the temperature range from -20 °C to 43 °C, the unit will not be affected by night, cloudy sky,
rain even snow weather.

2. Refrigerant circuit
Compressor: RJSM125V1WFZ, R134a high efficiency compressor, supplied by GMCC.
Evaporator: copper tube and aluminum fin type heat exchanger.
EXV: electronic expansion valve, the opening is regulated according to the discharge air temperature
of compressor.
Fan: centrifugal fan, there is three speeds. The motor is supplied by Welling.
ATCO (Temperature Switch): If the water temperature is too high, or higher than 78 °C, the ATCO
will automatically shut off the compressor and E-heater’s power supply, and turn it on if the
temperature falls down below 68 °C.
TCO (Temperature Switch): If the water temperature is higher than 85 °C, the TCO will
automatically shut off the compressor and E-heater’s power supply, it must turn on by manual.
High Pressure Switch: When the discharge pressure of compressor is 2.76MPa or higher, the
protection switch will be triggered, and if the discharge pressure is down to 2.07MPa, the protection
switch will be recovered.

8. Installation
Transport
² The unit is so heavy that it should be carried by two or more persons. Otherwise, it might
cause injury and damage.
Location of installation
² Enough space for installation and maintenance shall be preserved.
² The air inlet and outlet should be free from obstacles and strong wind.
² The base surface should be flat, which should be inclined no more than 2°, and able to bear
the weight of the unit.
² If the unit has to be installed in the indoor space, the unit might cause indoor temperature
decreased and noise, please take preventive measures for this.

Water system piping
² In case of installing the unit at a place where outside temperature below freezing point,
insulation must be provided for all hydraulic components.
² Water inlet or outlet pipes: The specification of the water inlet or outlet thread is RC3/4”,
which is external thread. Pipes should be heat-insulated well.
² Installation of the one way valve: The specification of the valve thread in accessories is
RC3/4”. It is used to prevent water from flowing backwards.
² The drainage pipe should be insulated to prevent water inside pipe from freezing in cold
weather.
² Do not dismantle the PT Valve, and do not block off the drainage pipe.
² 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.
² If the inlet water pressure is less than 0.15MPa, a pump should be installed at the water
inlet. If the water supply hydraulic is higher than 0.65MPa, a reducing valve should be

installed at the water inlet pipe.
² Condensate may be leaked from unit if drainage pipe is blocked, so a drainage pan should
be installed.
² To smoothly drain condensate, the unit should be installed at a horizontal floor. Otherwise,
the drain vent is ensured at the lowest place, and recommending the inclination angle of unit
to the ground should be no more than 2°.

² The duct’s resistance will decrease air-flow-rate, and capacity of unit will be decreased.
² It is recommended to install the unit in the indoor space. It is not allow installing the unit at
the rainy space.
² In terms of the unit connect with duct reaching to outdoor, and then a reliable water-resistant
measure must be conduct on the duct, to prevent water from dropping into internal of the
unit.
² Filter should be installed at the unit inlet, if the air inlet is not connected with duct. In terms of
the unit with duct, filter should be put on the position of duct inlet.

Electric connection
² If the power supply is not earthed well, the unit should be not installed.
² The reliable earthing connection and the installation of the unit should be done by a
qualified person.
² The power supply should be an independent circuit with rated voltage.
² An all-pole disconnection device which has at least 3mm separation distance in all pole and
a residual current device (RCD) with the rating of above 10mA shall be incorporated in the
fixed wiring according to the national rule.
² Set the electric leakage protector according to the relevant electric technical standards of
the local.
² The power cord and the signal cord shall be laid out neatly and properly without mutual
interference or contacting the connection pipe or valve.
² After wire connection, check it again and make sure the correctness before power on.
