General diagram of the refrigerating circuit
The heat pump is reversible allowing the swimming-pool’s heating or
cooling:
Swimming-pool water’s heating mode:
The cold and liquid refrigerant fluid absorbs the heat contained in the air through the evaporator (gilled
radiator), in which it is vaporizing; it is then put up in pressure and in temperature by the compressor
which sends it in the condenser (exchanger) where it loses its heat (in giving it to the water of
swimming pool) and comes back in liquid state; it loses its pressure and still cools in the expansion
valve before turning back to the evaporator for a new cycle.

Swimming-pool water’s cooling mode:
The 4 way valve reverses the circulation of the refrigerant fluid; the fluid vaporizes in the exchanger
(evaporator) in getting the heat of the water, goes through in the compressor which reheats it and
through in the gilled radiator (which becomes condenser) where it comes back to liquid state.

Safety and control systems
Heat pumps are equipped with the following standard protection
systems:
1. Water flow switch
Thanks to this flow switch, the heat pump will not work when the filter pump is not working (and the
water is not circulating). This system prevents the heat pump from heating only the water flow in the
heat pump itself. The protection also stops the heat pump if water circulation is cut off or stopped.
2. Refrigerant gas high and low pressure protection
The high pressure protection makes sure the heat pump is not damaged in case of
overpressurisation of the gas. The low pressure protection emits a signal when refrigerant is
escaping from the conduits and the unit cannot be kept running.
3. Overheating protection on the compressor
This protection protects the compressor from overheating.
4. Automatic defrost control
When the air is very humid and cold, ice can form on the evaporator. In that event, a thin layer of ice
appears that will grow increasingly bigger as long as the heat pump is running. When the
temperature of the evaporator has become too low, automatic defrost control will be activated, which
will reverse the heat pump cycle so that hot refrigerant gas is sent through the evaporator during a
brief period of time to defrost it.

5. Anti-frost protection during winter
Anti-frost protection can only be activated when the heat pump is in STAND-BY mode or shu
tdown protection:
1) During standby mode, when the ambient temperature ≤5℃, First anti-frost protection activated.
Water pump will run automatically each10 minutes. When the ambient temperature ≥8℃, First anti-f
rost protection off.
2) When the heat pump shut down, and ambient temperature ≤5℃, outlet water temperature ≤2℃,
Second anti-frost protection activated. Heat pump will turn on automatically and run in heating mod
e. When ambient temperature ≥8℃ or outlet water temperature ≥15℃, Second anti-frost protection
off.
If outlet water sensor fault, inlet water sensor will be use instead.
If outlet water sensor and inlet water sensor both fault, First anti-frost protection activated.
3) During anti-frost protection, the display shows code E04.

5- Installation
Rules of installation:
Electric and hydraulic connections must be carried out according to standards
in effect (NF C 15 100, CE I 364).
The machine must be installed outside.
The machine must be posed on its ant vibratory studs, set and lying flat and on a
massive base (concrete slab); this base must have a sufficient height to prevent any
entry of water by the bottom of the machine. Height must be adjusted to fit the
connector collecting the condensates.
The obstacles such as wall and vegetation must be separated from the machine as
indicated on the diagram below.
Exhausting Blowing
side side
Do not to install the Heat pump in a confined place (the fan would recycle its air and
the Heat pump would be down performance).
The fan should not blow towards the windows or crossing point.
Safety distance between the swimming pool and the foot bath: the fitter must
imperatively refer to the standard C15-100 section 702; the machine should not be
installed in volume 1 surrounding the swimming pool but at least in volume 2 so at a
distance of 3 m minimum of the swimming pool and foot bath.
Other precautions of installation:
- Do not to install the machine near a way with circulation of car in order to avoid
mud projections.
- Avoid directing blowing against dominant winds.
- If the machine is intended to be used in winter, put it in a place protected from the
falls of snow.
- The machine must be able to be supervised in order that children do not play

Electric connections:
CAUTION: before connecting the machine, make sure that the feeder is disconnected
to the electrical network.
The electric installation must be carried out by an experienced electrician and the
supply must come from a severing equipment and differential protection; the whole
must be carried out according to standards' in force in the country where the material
is installed.
Characteristics of the electric supply:
- 230 V +/- 10%, single-phase current, 50 Hz
- Mode of neutral TT and TN.S; the circuit of heat pump must be connected to an earth
circuit.
Characteristic minimum of the protection:
- Protection must be of 16 A, by circuit breaker or fuse; it must protect the Heat pump
exclusively; the circuit breaker must be specified with curve D, the fuse must be
specified Am.
- Differential protection : 30 mA (the length of cable between the connector block of
the heat pump and the protection of should not exceed 12 m).
Control :
The heat pump is fitted out with a water flow detector which function is to apply
the signal to the electronic card when the water flow is sufficient.
We recommend when it is possible to control the heat pump to the filtration pump
(by contacting relay non supplied to insert in the feeding circuit of the heat pump).
The remmonded water flow speed is 5~12m³/h(Depending on the model).
Removed control panel:
An extension cord allows the removal of the panel in inserting it in a standard
electric box into the technical local; the option is supplied with a cover allowing to
seal the aperture let by the removal of the control panel.

6- Water Flow and refrigerating circuit pressure
After putting into service, do the settings of pressure of the refrigerant circuit
for having an optimal operating of the heat pump, following:
Stage 1:
Before starting the Heat Pump, ambient
temperature around 20°C, refrigerant meter
shows pressure from 14 to 16kg/cm².
Stage 2:
Close completely the by pass valve and open
large inlet and outlet valves of the Heat
Pump; in these conditions the totality of the
water flow goes by the Heat Pump.
Put into service the Heat Pump in heating mode, wait for the indicated pressure
being stabilized; the correct setting of the pressure is from 21 to 35 kg/cm²;
In most of cases (pump of filtration given a flow until 20m³/h) you do not have to
open the by pass valve.
If the stabilized pressure is under 21kg/cm², the progressive opening of the by
pass valve will allow rising this pressure.
The adjustment of the by pass valve done, you have in principle no reason to
modify it during the season. See the paragraph “Environment problem” too.

7- Defrosting
1. Defrosting conditions under heating mode:
When heating, the cumulative running time of the compressor ≥45min (parameter 11)
, and the continuous running time of the compressor ≥5min;
Cooling coil temperature <-3°C (parameter 12);
①(ambient temperature - cooling coil temperature) ≥5°C (parameter 15), and -7 °C
≤ambient temperature ≤17°C (parameter 16) for 30 seconds;
②(ambient temperature - cooling coil temperature) ≥9°C (parameter 15 + 4°C), and a
mbient temperature < -7°C for 30 seconds;
When the above conditions are all met, it will enter defrosting; (Note: ①and ②only n
eed to meet one of them)
When the temperature of the cooling coil is faulty, and the ambient temperature is ≤
20°C, the defrosting will be timed, and the defrosting time is every 10 mins;
2. Defrosting conditions at startup:
When the stop/standby/compressor cut off time ≥30min;
-7°C ≤ambient temperature ≤3°C, and coil temperature <-3°C (parameter 12);
When the compressor starting condition is met (the water temperature is lower than
the backlash/starting temperature, but still not started), and the above conditions ar
e met, it will enter defrosting; .
3. Defrost operation frequency: When entering defrost, the frequency is fixed at 60Hz.
4. Condition for exit the defrosting:
After 2 minutes of defrosting, when the cooling coil temperature is ≥20°C (parameter
14) or the defrosting time reaches 10 mins (parameter 13), it will exit the defrosting.
5 Defrosting steps:
When the defrosting conditions are met, following steps will start:
1) Compressor stops, and fan stops after 15 seconds;
2) The four-way valve is energized at 55 seconds;
3) The compressor restarts at 60S;
4) The water pump keeps running;
The following steps will be performed when the defrosting exit condition is satisfied:
1) Compressor and fan stop;
2) The four-way valve loses power at 55S;
3) The fan is turned on at 60S, and the compressor starts after 5 seconds to resume
normal heating running;
6 The abnormal exit of the defrosting:
1) When the error protection occurs during defrosting, the system immediately exits
the defrosting and stops running;
2) Low pressure protection is not detected during defrosting;
7 Coercive defrosting: When the cooling coil temperature is lower than the defrostin
g exit temperature, press and hold the “M” +
“▼” buttons for 3 seconds to enter the coercive defrosting.

8 – Environment problem
Under certain external conditions the heat exchanges between the refrigerant and the
water on one hand and between the fluid and the air on the other hand are insufficient;
the consequence is that the refrigerating circuit runs up in pressure and the
compressor consumes more electricity.
The temperature sensors compressor outlet and the magnetic circuit breaker on the
compressor power supply protect the compressor from these extreme conditions; the
error messages E 12 occur.
The condition causing this situation is as follows:
In heating mode:
- insufficient water flow:
close the by-pass valve for increasing the refrigerant exchange water
In cooling mode:
- too important water flow: open the by pass valve for decreasing the water flow and
so the exchange water refrigerant
- insufficient air flow: be sure that the real net of condenser are not blocked.
Note: these error codes are likely to occur if temperature of swimming pool water is
high and the ambient air is hot.

This table explains the error codes caused by a defective regulating
component or by a security operation.
