2.3 Operational Principle
Heat Pump System Theory:
(1) Using a small power input to drive the compressor, the power used is Q1.
(2) While the unit is running, the power that comes ambient air is Q2 (from the refrigerant
transformation).
(3) The energy that the water gets from the unit is Q3.
(4) According to the law of conservation of energy:
﹛ Sum of input power = sum of output power Q1+Q2 = Q3
﹛ In standard working conditions, the power that heat pump gets from the environment is about
3.2 times the power input, Q2 = 3.2 x Q1
so: Q3 = Q1+Q2 = Q1+3.2Q1= 4.2Q1
Which means you can get 4.2Q1 from heat pump if you spend Q1 energy. Which means the
energy that you can get from heat pump after using 1 kW of electricity is equal to the energy that
you get from electrical element heater after using 4.2 kW of electricity. This makes the hot water
heat pump is one of the most energy efficient heating equipment available on the market today..

3.Operation
3 min safety protect
If the unit stops and you re start the unit or turn it on manually, the unit will not start to run
again for approx 3 minutes. This is a protection feature to safe guard the compressor.
In low ambient conditions the heating output decreases. See page __ for further
information.
Heating capacity
In order to use the unit correctly, please run the unit at environment temperature -7→-43→.
The unit includes sophisticated electronic devices, prohibited to use water from lake, untreated
river water and groundwater!
Working conditions
Defrosting
In heating mode the unit will defrost automatically, maximizing the heating efficiency (Lasting 2 10 minutes).
The fan motor will stop running whilst the unit is defrosting.
Overheating protection
When the water temperature reaches 75deg C, the power of the unit will be cut and must be
manually reset. See page __ for more information.
Water pressure protectiontemperature or
A P&T valve MUST be installed in the tank. When the tank pressure reaches 0.85MPa or
when the tank temperature reaches 93deg C, the P&T valve will open automatically so as
to reduce the pressure or temperature decrease.

ATTENTION
Pipeline connection explanation
Installation of the water inlet or outlet pipes: The specification of the water inlet and
outlet thread is BSP3/4”(internal thread).Pipes must be heat-resistant and durable.
Installation of the pipe for P&T valve: The spec of the valve connecting thread is
BSP3/4”(internal thread).After installation, please confirm that the plumbing outlet is
exposed to the air. When flexible plumbing is connected to the pressure relief
outlet of this valve, please confirm that the plumbing is vertical and exposed to the
air.

ATTENTION: The P&T valve attached to the unit MUST be installed, or it will cause
damage to the unit and pose a serious risk to passersby.
Installation MUST comply with AS/NZS3500.4 and all other relevant Australian
Standards and Industry Codes.
Do not use stainless steel fittings to connect directly with other metals to prevent
galvanic corrosion.
If installed outdoors all fittings and insulation must be weather resistant
.

4.2 Freight and Transportation
As a rule, the unit should be stored and/or transported in its shipping container in an upright
position and without water charge. For transport over short distances, and provided due care
is exercised, an inclination angle of up to 30 degrees is permitted. During transport and
storage, ambient temperatures of - 10 to +60deg C are permissible.
4.2.1 Transport using a forklift
When transported by a fork lift, the unit must remain mounted on the pallet. The lifting speed
should be kept to a minimum. Due to its top-heaviness, the unit must be secured against
tipping over. To prevent any damage or injury, the unit must be placed on a level surface.
4.2.2 Manual transport
For the manual transport, the wooden pallet can be used for bottom part.
Using ropes or carrying straps, a second or third handling configuration is possible. With this
type of handling, care must be taken that the maximum permissible inclination angle of 60
degrees is not exceeded. If transport in an inclined position cannot be avoided, the unit should
be left to rest at least one hour after it has been moved into final position before operation.
CAUTION! High center of gravity, Place on a level surface!
