Ⅰ . Introduction
Safety precaution
-The swimming pool heat pump must be installed by a qualified electrician.
-Always install a differential protective device with a sensitivity of 30 mA on the
distribution unit before the electrical box.
-Always fit a circuit breaker for all active conductors on the power supply of the box.
-In the event of abnormal behavior (noise, smell, smoke), cut off the power supply
immediately and contact you reseller. Do not attempt to repair the system yourself.
-Keep the main power supply switch far from children.
-Rotating parts: Never remove the grid from the fan. Never place your hand or any other
object in the air inlet or outlet of the heat pump.
Important features of this product
Water Flow Switch
The water flow switch contacts close when pressure is applied as pool water flows through
the titanium heat exchanger. Low flow rates as well as no flow will let these contacts open
and this will cause the unit to shut down. The LED display will read “EE3” if the water
pressure is not sufficient.
Always switch off power supply
before working on the heat pump
and stop the hydraulic circuit.
This swimming pool heat pump is equipped with safeguards that will stop
operation to protect your unit automatically and display error code on the
LED controller in case of some events as following:
Caution: Danger of electric shock

2
High / Low Refrigerant Pressure Switches
•The high-pressure switch senses the refrigerant pressure in the sealed refrigeration system
and shuts the heat pump down in the event unsafe operating pressures are reached. The heat
pump will automatically reset after the system pressure drops back to normal operating
pressures. When this switch is tripped, digital displays will read “EE1”
•The low-pressure switch senses the refrigerant pressure in the sealed refrigeration system
to protect against certain conditions that could be detrimental to compressor life. The switch
shuts the unit down in the event of loss of refrigerant or not enough refrigerants. The switch
automatically resets when the pressure rises to normal operating pressures. The display will
show “EE2” if this switch is tripped.
Low Ambient Temperature
If the air outside the heat pump is not warm enough to produce heat, the system will shut
down. The actual point at which your unit will shut down due to low temperature varies
depending on current weather conditions, the amount of sunlight reaching the heat pump.
The shutdown can occur anywhere within a wide range of temperatures, usually below 0
degrees. A shutdown occurs because low temperatures will activate the systems
low-pressure safeguard switch (digital controller will display a code “PP7”.) The unit will
start up again when the temperature has raised enough to reset this switch.
Time Delay
All models use a 3-minute time delay to prevent repeated tripping of the compressor thermal
overload, which is caused by attempting startup before system pressures are equalized. Any
interruptions, outside of power loss, will result in a 3-minute time delay.

Transport it in proper manner
1. Transport it in original package.
2. When moving the machine, do not lift the water nozzle since the titanium heat exchanger
inside the machine will be damaged. Please refer to the following wrong operation
picture:
Determining Optimum installation position
The location of the swimming pool heat pump is very important for efficient operation,
think about the following factors when choose the proper place:
Avoidance of air recirculation
Easy for wire and pipe connection and Water pipe line of long water lines (not
longer than 10m.) from heater to pool.
Easy for maintenance.
Drainage of condensation.
Pay attention to the following points:
1．The heat pump must be installed OUTSIDE in a well ventilated place to avoid air
recirculation or in a place with adequate room area both for installation and
maintenance. Please refer to the following illustration:
A minimum of 300mm of clearance from walls, shrubbery, equipment, etc. is required around the entire
pump circumference. This allows for ample air intake. No less than 800mm clearance on the air outlet is
required to prevent re-circulation of air. We recommend not placing the unit underneath eaves, decks, or
porches, as this causes recirculation of discharged air, or the efficiency of the heater will be reduced or
even stopped.
The manufacturer cannot accept responsibility for damage incurred or repairs
necessitated due to improper handling of our equipment.
!!Warning:
Because the machine is very heavy, the
water nozzle can not bear to be lifted during
transit or installation

6
2．The heater should be located on a solid, level and non-corrodible structure that is
capable of supporting the weight of the heat pump. It must be fixed by bolts (M10) to
concrete foundation.
3．The heat pump should be far from any source of combustibles and corrosive material to
Wrong installation
!!Warning:
Don’t install the heat pump close to
a wall or plants. And Never inside a
closed building!
!!Warning:
The machine must not be hung onto the
wall with soft pipe since the inlet/outlet
union on the machine can’t hold weight.
The machine must always be connected
with hard pipe!

7
avoid any damage to this unit.
Never place heat pump near sprinkler systems, evaporation of acid or alkaline gas. If you live in an
oceanfront area, the heat pump should be placed out of direct spray of sand and salt, since this will also
clog, damage, and corrode the unit. You may consider protecting your heat pump by planting shrubbery
or a privacy fence between the unit and the prevailing beachfront wind.
4．When the machine is running, there will be condensation water discharged from the
bottom. Make sure there is enough space for water drainage.
Water pipe connection
-The water flow through this machine needs to be driven by an appended water pump
(Prepared by the user). The recommended pump specification-flux is shown on the
product specification and Max. lift ≥10m;
-Pipe length between heat pump and swimming pool should not be longer than 10m.
TIPS: HEAT PUMPS GENERATE WATER CONDENSATION DURING NORMAL
OPERATION.THISSHOULDNOTBEMISTAKENFORALEAKINTHE UNIT.
Noted: The drawing is just for demonstration, and layout of the pipes for reference.

8
Electric connection
-Wiring must be handled by a professional technician according to the circuit diagram as
following.
-Connect the heat pump to appropriate power supply and the voltage should comply with
the rated voltage of each model stated on the specification.
-Make sure the machine is ground well.
-Always put leakage protector according to the local code for wiring (leakage operating
current ≤30mA).
-Protect the circuit with a suitable circuit breaker or fuse (as it is shown in table on page 9)
Attention: The swimming pool heater must be earthed well.

Recommendation for protecting devices and cable specification
※Above data is subject to modification without notice.
Note: The above data is adapted to power cord ≤ 10 m .If power cord is ＞10 m, wire
diameter must be increased. The signal cable can be extended to 50 m at most.
Trial after first installation
Inspection before connecting power supply
-Check the installation of the whole machine and the pipe connections according to the
pipe connecting drawing.
-Check the electric wiring according to the electric wiring diagram, and ground well.
-Make sure no blockage on the air inlet and outlet, or the efficiency of the heater will be
reduced or cause machine to stop operation.
Trial after connecting power supply
-Connect the machine with electric power supply, then relative information will display on
the LED controller.
(For Detail operation of LED controller, please refer to Chapter “Operation guide”.)
-Start the water pump before turning on the Machine to avoid any damage.
-Press power on/off on LED controller to turn on/off machine.
-During the first start of machine, please check if there is any water leakage in the piping
connection system. Then set suitable temperature.
