injury. Do not operate the unit without
the safety grill in place.
Important: Ensure that the plug remains
clean, free from moisture, foreign objects
and dirt. Ensure that the plug is properly
inserted or hard wired by a qualified
electrician.
If the unit operates abnormally, stop
the unit by firstly switching it off and
then unplug the unit. For example, if
there is a strange smell or abnormal
noise coming from the unit.
Do not clean the appliance with water.
Water will go into the unit and will destroy
the insulation.

Do not touch the plug with wet hands,
as electric shock can occur.
Ensure that the power to the heat pump is
disconnected before removing leaves,
particles or other foreign objects from the
air inlet vanes.
Verify the network specifications, with the unit data recorded on the heat pump
prior to installation.
Any additional disinfectant systems, such as chemical or electrolysis are not
recommended for use with this hot water heat pump. The pump MUST be installed
prior to these systems.

3 - Installation
3-1 Locating the Unit
It is important to install the hot water heat pump in accordance with the following
instructions. Water and electrical connections must be carried out by a suitably
qualified tradesman or installer
•
•
•
•
•
•
•
The appliance must be installed outside.
The appliance must be mounted on its anti-vibratory studs, positioned on
a substantial platform (concrete or steel pad). The platform must have
sufficient height to prevent water entering the bottom of the unit and also
allow the condensate to drain freely from the connection at the bottom of
the unit
Vegetation and other obstacles must be kept clear of the unit, in
accordance with the minimum distances detailed below
The unit should be positioned so that the exhaust does not blow towards
windows or doorways.
There must be a minimum clear distance above the unit of 1.5m
The stability bracket on the back of unit must be securely fixed to a post
or wall so as to position the unit vertically and prevent any movement of
the unit.
Connect the drain pipe to the condensate outlet and direct it away from
the unit.
Caution
•
•
•
•
Do not install the appliance in an area where dirt, mud, mown grass or
other foreign objects could affect airflow around the unit causing damage
or operational issues.
Shelter the unit from prevailing winds
Shelter the unit from falls of snow or heavy rain fall
Prevent children from playing on or around the unit

3-2 Water connections
Please refer to the diagram below:
1) Connect the hot water in pipe (hot water supply pipe) to the outlet port on the
hot water cylinder. Pay attention to heat preservation and ensure appropriate
thermal insulation of the pipe work. It is important that the unused hot water
outlet port be properly capped. The plastic transport caps are not suitable for
this function.
2) Install a water filter (where necessary) and one-way valve in the tap water (
inlet water pipe) and then connect the tap water pipe (inlet water pipe) to the
inlet port on the tank.
3) Fill the tank with water. Open the tap water (inlet water) in-valve allowing the
tank to fill with water; Meanwhile, open the hot water out-valve, until the water
spills over from the hot water out valve. Once this happens the tank is full of
water. Close the tap water (inlet water) in-valve, check and ensure that there
is no leakage in the system. Re open all valves.
Attention: Be sure the tank is full of water before it is switched on.
Warning: The inlet and outlet plastic caps are for transport only. Any
unused inlet or outlet ports must be blanked off properly using compliant
metal pipe caps.

3-4 How the reversible heat pump operates
By using the free energy contained in the ambient air, the heat pump enables
the heating of the water in a very economical way. Your heat pump is a heat
machine that can transfer the heat from a low temperature area (ambient air) to
a higher temperature area.
How the pump operates in heating mode:
The heat of the air is absorbed by the cold, liquid refrigerant, through the
evaporator (radiator with wings), the refrigerant is vaporised. Then the
compressor increases the pressure and the temperature, and sends it into the
condenser (exchanger) where it loses its heat by transferring it to the water. The
refrigerant then returns to the liquid state, it loses its pressure and cools again,
flowing into the pressure reducer before returning to the evaporator for a new
cycle.
Operating cooling mode or defrosting mode:
A 4 way valve enables a reverse cycle of the refrigerant; this fluid liquid is
vaporized in the exchanger (the evaporator) by taking the heat out of the water,
which then passes into the compressor that heats it and in turn sends it to the
radiator (the condenser) where the refrigerant returns to it's liquid state.
Note: Single water heater without cooling water mode; Single water chiller
without heating water mode and defrosting mode.

Press the power button
when the unit has received the signal it gives out
two 'beep' tones. The operation light switches on and the heat pump water
heater starts operation. The compressor will restart after 3 minutes to protect
the system if the interval is shorter than 3 minutes from the last shut down to the
present switch on.
Mode Selection
Press the 'M' button to chose the mode of heating and cooling (this key is
invalid for the single water chiller or single water heater)
Temperature Setting Selection

5 - Instructions for the Installer
The installer must read the following and provide instructions to the purchaser.
5-1 Unit controller and parameters
The Heat Pump is Equipped with 2 Control Devices:
•
•
•
A defrost temperature probe, located on the evaporator, starts the defrost
sequence.
A thermal probe located on the exchanger ensures the cut of the heat
pump when the temperature of the water reaches the temperature
required.
The meaning of the code name
T1: water temperature
T2: ambient temperature
T3: exhaust temperature from compressor
T4: coil temperature in outdoor heat exchanger
TC: water temperature setting
Control Function:
1) TC can be set between 10C-35°C in cooling mode. Original TC is 18°C.
When T1≤T°C -1°C, Compressor and fan motor stop; When T1≥T°C
+1°C, Compressor and fan motor start.
2) TC can be set between 45°C -60°C in heating mode. Original TC is
50°C. When T1≤TC-1C, Compressor and fan motor start; When
T1≥TC+1C, Compressor and fan motor stop. When compressor is
running, if T2≤12°C, the four way valve2 on; if T2≥12°C, the four way
valve2 off.
5-2 Defrost operation:
1) Defrost:
The system begins to defrost if the following three terms are met in the
same time:
a) T4≤-5°C lasts for a while;
b) compressor runs continuously for more than 5 minutes
c) Compressor runs accumulative total for 45 minutes
While the system begins to defrost, compressor and fan motor stop first and
four way valve1 is on after 1 minute and begins to work. The compressor
restarts after it has stopped for 3 minutes. If the sensor for T4 is damaged, the
system begins to defrost, after the compressor has run continuously for 45
Premier Heat Pumps – Water Heater and Chiller Manual
Page 16
minutes.
2) Parameters for Exiting Defrost Mode:
• When defrosting time reach 3 minutes and T4 reaches 10°C or defrosting
time reaches 8 minutes, defrost exits and starts heating water mode.
While defrost is exiting, after compressor and fan motor have stopped for
1 minute, the four way valve1 is turned off.
• The Compressor will restart after it stops for 3 minutes, and the system
will run the same mode as before defrosting.
5-3 Fault Codes and Fault Descriptions
Failure Code:
E1: sensor for T1 (water temperature) failure
E2: sensor for T2 (ambient temperature) failure
E3: sensor for T3 (exhaust temperature from compressor) failure
E4: sensor for T4 (coil temperature in condenser) failure
E5: Compressor stops three times in 24 hours because the current is too high.
E6: While heating water, there is three times of T3≥100°C in 24 hours.
E7: There is electrical leakage in the compressor or outdoor motor or four-way
valve
Recommendation: Contact the installer or service agent
6 - Maintenance Instructions
