3. Installation
(1) The heat pump unit must be installed by professional technicians .otherwise unit may be
damaged or body injured, even dead
(2) The unit is designed for outdoor location with good ventilation. Recirculation of cold
discharge air back into evaporator coil will greatly reduce heating capacity and efficiency
of the unit, which will void the compressor warranty.
(3) The unit can be installed almost anywhere in the outdoors. To get a good performance, it
needs to meet the three factors :
a) Good ventilation
b) Stable and reliable power supply
c) Recycled water system
The difference from gas water heater, it should not bring environmental pollution or have
the installing problems in-windy areas.
(4) The unit should not be installed in a limited air ventilation area ,or placed in a bush where
it will block the air inlet .
These location deny the unit of a continuous source of fresh air .When seasons changing, it
may stick leaves on the evaporator coil , thereby reducing its efficiency and impact of its
service life .
(5) For indoor installation, please consult more instruction from technicians.
(6) When install a bypass, it should be not exceed 30% of nominal flow rate.
(7) Must make Water level higher than the circulation pump location.
(8) Below picture show the minimum required distance on each side of pool heat pump unit.
(9) Typically, the pool heat pump unit should be installed aside the pools, less than 7.5 meters
distance.
(10) To get the best heat exchange of heat pump unit, it should be matched the normal rate of
water flow recommended in specification sheet.
(11) It is required to increase the discharge pipe to prevent freezing in cold season, to put T
fitting and ball valve to facilitate changing the water in winter or emptying the water out
of system to prevent freezing when HP stop operating at the ambient temperature below
zero ,otherwise the unit may be damaged .
(12) It is suggested to install the quick adapter in front of water in-out connection, which could
discharge water easily to prevent water freezing, and be convenient for maintenance and service.
(13) When unit running ,there will be some condensation water discharged from the bottom,
please hold the drainage nozzle (accessory ) into the hole and clip well ,and then connect
a pipe to drain the condensation water out.
9
(14) If water pressure is over 10 KPA, or water flow rate is more than 11 cubic meters through
heat exchanger, it is necessary to install the by-pass pipe in water system.
(15) Installation illustration
NOTE: The factory only provides the heat pump unit. The other items in the
illustration are necessary spare parts for the water system which are provided
by users or installers.
ATTENTION: Please follow these steps when operating the first time :
1. Open the derivation valves for charge water and close the valve (direct)
2. Make sure that the pump and the water-in pipe have been filled with water
3. Start the unit
(16) The location of chemical’s instruction to your system is also critical to the heater’s life.
If an automatic chlorinator or brominates is used, it must be located downstream
of the heater.
A trap must be installed between the chlorinator and the heater to prevent chlorine return
into the heat pump. (See below pictures)

4. Adjusting the bypass
Use the following procedure to adjust the bypass:
• fully open all three valves
• slowly close valve 1 until the water pressure is increased by approximately 100 to 200 g
• Close valve 3 approximately half-way to adjust the gas pressure in the cooling system
• If the display shows „ON“ or error code EE3, close step by step the valve 2, to increase
water flow and stop when the code disappear.
Optimal operation of the heat pump occurs when the cooling gas pressure is 22 ±2 bar.
This pressure can be read on the pressure gauge next to the control heat pump panel. Under
these conditions the water flow through the unit is also optimal.
Note: Operation without a bypass or with improper bypass adjustment may result in sub-optimal heat
pump operation and possibly damage to the heat pump, which renders the warranty null and void.
5. Initial operation
Note: In order to heat the water in the pool (or hot tub), the filter pump must be running to
cause the water to circulate through the heat pump. The heat pump will not start up if the
water is not circulating.
After all connections have been made and checked, carry out the following procedure:
1. Switch on the filter pump. Check for leaks and verify that water is flowing from and to the
swimming pool.
2. Connect power to the heat pump and press the On/Off button on the electronic control
panel. The unit will start up after the time delay expires (see below).
3. After a few minutes, check whether the air blowing out of the unit is cooler.
4. When turn off the filter pump , the unit should also turn off automatically, if not, then
adjust the flow switch.
5. Allow the heat pump and the filter pump to run 24 hours a day until the desired water
temperature is reached. The heat pump will stop running at this point. After this, it will
restart automatically (as long as the filter pump is running) whenever the swimming pool
water temperature drops 2 degree below the set temperature.

Depending on the initial temperature of the water in the swimming pool and the air temperature,
it may take several days to heat the water to the desired temperature. A good swimming pool
cover can dramatically reduce the required length of time.
Water Flow Switch:
It is equipped with a flow switch for protecting the HP unit running with adequate water flow
rate .It will turn on when the pool pump runs and shut it off when the
pump shuts off. If the pool water level higher than 1 m above or below the heat
pump’s automatic adjustment knob, your dealer may need to adjust its initial
startup.
Time delay
The heat pump has a built-in 3-minute start-up delay to protect the circuitry and avoid excessive
contact wear. The unit will restart automatically after this time delay expires. Even a brief
power interruption will trigger this time delay and prevent the unit from restarting immediately.
Additional power interruptions during this delay period do not affect the 3-minute duration of
the delay.
Condensation
The air drawn into the heat pump is strongly cooled by the operation of the heat pump for
heating the pool water, which may cause condensation on the fins of the evaporator. The
amount of condensation may be as much as several liters per hour at high relative humidity.
This is sometimes mistakenly regarded as a water leak.

Electrical connection
Note: Although the heat pump is electrically isolated from the rest of the swimming pool system,
this only prevents the flow of electrical current to or from the water in the pool. Earthing is
still required for protection against short-circuits inside the unit. Always provide a good earth
connection.
Before connecting the unit, verify that the supply voltage matches the operating voltage of the
heat pump.
NOTE:
(1) Above electrical wiring diagram only for your reference, please subject machine posted
the wiring diagram.
(2) The swimming pool heat pump must be connected ground wire well, although the unit
heat exchanger is electrically isolated from the rest of the unit .Grounding the unit is still
required to protect you against short circuits inside the unit .Bonding is also required.
Disconnect:
: A disconnect means (circuit breaker, fused or un-fused switch) should be located within sight
of and readily accessible from the unit .This is common practice on commercial and residential
heat pumps. It prevents remotely-energizing unattended equipment and permits turning off
power at the unit while the unit is being serviced.
10. Maintenance
(1) You should check the water supply system regularly to avoid the air entering the system
and occurrence of low water flow, because it would reduce the performance and reliability
of HP unit.
(2) Clean your pools and filtration system regularly to avoid the damage of the unit as a result
of the dirty of clogged filter.
(3) You should discharge the water from bottom of water pump if HP unit will stop running for
a long time (specially during the winter season).
(4) In another way, you should check the unit is water fully before the unit start to run again.
(5) After the unit is conditioned for the winter season, he is preconize to cover the heat pump
with special winter heat pump.
