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 4way valve reverses thecirculation 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 over
pressurisation 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.

13
5. Anti-frost protection during winter
This protection can only be activated if the heat pump is in STAND-BY mode.
5.1 First anti-frost protection
If the filter pump is controlled by the heat pump (regardless of the value for parameter 9) and
when the water temperature lies between 2 and 4 °C and the air temperature is lower than
0 °C, the filter pump will be automatically turned on to prevent the water from freezing in the
piping. This protection is deactivated when the temperature rises again.
5.2 Second anti-frost protection
If the water temperature drops even more, that is, below 2 °C (during long frost periods), the heat
pump will also start running to heat the water until its temperature approximates 5 °C. When this
temperature is reached, the heat pump will stop, but anti-frost protection will remain active until
conditions change.
6. 3-fase protection
If the phases are connected in the wrong order due to electrical mis-wiring, this protection
will interrupt
the power supply to prevent mechanical deformation. There will be an EE 4 error code on
the display.

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 anti-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, or 380 V +/- 10%, three-phase current,60 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 8m³/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, as 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 9m³/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 –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 3 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 heavy 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.

8. Maintenance and inspection
8.1 Maintenance
•Check the water inlet and drainage often. The water and air inflow into the system
should be sufficient so that its performance and reliability does not get compromised.
You should clean the pool filter regularly to avoid damage to the unit caused by clogging
of the filter.
•The area around the unit should be spacious and well ventilated. Clean the sides of the
heat pump regularly to maintain good heat exchange and to save energy.
•Check if all processes in the unit are operational and pay special attention to the
operation pressure of the refrigerant system.
•Check the power supply and cable connections regularly. Should the unit begin to
function abnormally or should you notice a smell from an electrical component, arrange
for timely repair or replacement.
•Winterizing : make sure to purge all the water from the heat pump and other systems
in order to prevent frost damage.
•You should also purge the water if the unit will not work for an extended period of time.
You should check all parts of the unit thoroughly and completely fill the system with
water before turning it on again afterwards.
8.2 Troubleshooting guide
Improper installation may result in an electrical discharge that could lead todeath of –or
serious injury to -pool users, installers or others due to electrical shock and may also cause
damage to property.
DO NOT attempt to modify the internal configuration of the heat pump.
1. Keep your hands and hair clear of the fan blades to avoid injury.
2. If you are not familiar with your pool filtering system and heat pump:
a. Do not attempt to adjust or service without consulting your dealer or your professional
pool or air conditioning contractor.
b. Read the entire installation and user manual before attempting to use, service or adjust
the unit.
c. Start the heat pump at least 24 hours after its installation in order to prevent
damage to the compressor.
Note: Switch off the power prior to maintenance or repairs.
