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 capillaries 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
The heat pump is fitted out:
Temperature control:
A temperature sensor of the evaporator, starting the
defrosting operation.
An ambient temperature sensor ensuring the cut of the heat
pump when the temperature of the external air goes down
under -15°C (factory settings). The normal cycle restarts when
the outside temperature goes up to -13°C (factory settings).
A temperature sensor placed on the exchanger, ensuring the cut of
the heat pump when the temperature of the water reaches the
required temperature. The normal cycle restarts when the
temperature in the exchanger goes down to a temperature lower of
3°C (factory settings) than this required.
With 4 safety systems:
A water flow detector placed at the exit of the exchanger
A high pressure gas circuit breaker, a low pressure gas circuit
breaker
An outlet compressor temperature sensor
If a defect occurs on one of these systems (defective system, off-line
or abnormal measured value) a message of defect appears on the
display screen; see the paragraph “Error codes and what to do” of this
note.
Caution: the removal or the shunt of one of the control or safety
systems involves the cancellation of the guarantee.

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
around

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 3.5m³/h.
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
The defrosting is necessary only in heating mode.
Sequences of the defrosting:
1- Start
The defrosting is engaged if the following conditions are at the same time
fulfilled:
- the defrosting sensor temperature goes down to -7°C
- the compressor runs without stopping for 5 minutes
- the compressor had run totally 45 minutes
2- The compressor and the fan stop
3- After 20 seconds, the 4 way valve shifts
4- One minute after its stop, the compressor starts alone and the accumulated
freeze on the gills becomes melting, what is generally with a steam cloud
5- Stop:
The defrosting stops if one of the following conditions is fulfilled:
- the defrosting operates 20 seconds and the detected temperature by the
defrost sensor goes up to 12°C.
- the compressor had run totally 3 minutes
6- The compressor stops
7- After 1 minute the 4 way valve shifts
8- Two minutes after its stop the compressor and the fan start for restarting
in heating mode.
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 EE 6 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.
