I. Operating principal and main components

This paragraph describes how Climexel heat pumps work. An understanding of the workings of the heat pump will help
you realise the importance of the preparation work that must be carried out before installing, using or maintaining your
heat pump.

A heat transfer fluid (R 410 A) travels in a continuous loop through a copper circuit. As it moves through the circuit it
experiences the following cycle:

1) captures calories from ambient air as it flows over the fin-type “evaporator”. The fan propels
ambient air over aluminium fins covering the copper tubes through which the liquid is flowing; the fluid
is heated by the ambient air which, in turn, is cooled down.

2) the fluid enters the “compressor”, here the fluid pressure is raised significantly thus further increasing its

temperature (all models except the MPI-160 are fitted with a Scroll type compressor)

3) the fluid passes into the “condenser” or plate type heat exchanger where calories are transferred from

the heat transfer fluid to the pool water, the fluid is cooled while the pool water is heated.

4) the fluid returns to its initial temperature and pressure in the expansion chamber and the cycle starts

again

The compressor and expansion chamber delimit two half-loops:

- the half-loop situated on the condenser side is referred to as the HP or High Pressure loop

- the half-loop situated on the expansion chamber side is referred to as the LP or Low Pressure loop

With an ambient air temperature of 15°C, CLIMEXEL heat pumps transfer 4 to 5 times more energy to the pool water
than they consume (90% of this energy is consumed by the compressor): these machines have a yield (or COP ­Coefficient of Performance) of between 4 and 6.

Heat is transferred to
the pool water from
the heat transfer fluid
within the plate-type
heat exchanger.

Pool water

The fan draws ambient air
in from the outside and
over the evaporator where
it heats up the heat transfer
fluid

The compressor increases
the pressure of the heat
transfer fluid and thus
raising its temperature
further

POWER INVERTER SYSTEM
On the contrary to the fixed speed (50 Hz) compressor equipping conventional On/Off hat pumps, the speed of the
inverter compressor can vary between 11 and 100 Hz.
Thus, when the ambient air temperature is low, or the heating demand is high, the inverter compressor runs at high
speeds (between 50 and 100 Hz). Inversely, when the heating demand is low, notably when the pool water

The expansion chamber
decreases the pressure of
the fluid thus lowering its
temperature

26/96

2016/03 - Indice de révision : E - Code : 0033340

As the ambient air temperature increases, more calories are transferred to the heat transfer fluid at the evaporator, and
then from the heat transfer fluid to the pool water in the condenser. Inversely, as the ambient air temperature falls, less
calories will be available for transfer to the pool water.
To provide a general idea, the following reduction coefficients should be applied to the power values quoted for an
ambient air temperature of 15°C if the machine is operated at lower temperatures.

To ensure correct operation and safety, CLIMEXEL heat pumps are fitted with several safety mechanisms:

- water flow controller, controls the flow of pool water entering into the condenser: shuts down the heat pump if
the water flow drops below a certain rate or stops completely (not enough calories being transferred from the
heat transfer fluid) ;

- LP pressure gauge, on the LP loop: stops the heat pump if the gas pressure is too low and allows the heat
pump to restart automatically when the pressure returns to normal, within the limit of 3 stop/start cycles per hour,
otherwise switches to fault mode (LP alarm)

- HP pressure gauge, on the HP loop: shuts down the heat pump if the gas pressure is too high, the machine
switches to fault mode;

- CLIMEXEL POWER INVERTER heat pumps feature numerous electronic safety mechanisms.

Start up of the compressor and evaporator is controlled by a regulator that allows:

- the user to choose a temperature (the set-point) to which the pool water should be heated;

- automatic start up of the machine if the pool water temperature drops below the set-point (unless filtration is
stopped and is not slaved to the heat pump) ;

- automatic shut down of the machine once the pool water reaches the set-point

- selection of the operating mode; Comfort or Eco

- selection of the configuration; heat or chill the pool water

temperature is around the set point, the Inverter compressor runs at low speed (between 11 and 50 Hz).
Operating at low speeds, the noise level is extremely low, the COP is optimised and the service life of the compressor
is extended.
Note: the actual operating range varies depending on the heat pump model.

The power levels or "STEPs" are managed automatically by the machine, they can be viewed from the thermostat
menu. STEPs range from 0 to 7, the higher the STEP the higher the machine's power level.
The machine features a safety mechanism that allows it to switch to a higher power level if it is taking too long for pool
water to reach the set point.

Note:
In Comfort mode, the machine will run at full power until the set point is reached.
In Eco mode, the machine will regulate its power as a function of the air and water temperatures in order to optimise
power consumption. In Eco mode it will take longer for the pool water to reach the set point than in Comfort mode.

Thermodynamic defrosting:

If the ambient air is very humid (rain, fog, etc.) and the air temperature is relatively cool (below 15° C), frost can rapidly
accumulate on the evaporator fins and thus hinder recovery of calories by the heat transfer fluid.

The frost must be melted before this phenomenon becomes too pronounced.

All CLIMEXEL heat pumps are equipped with an automatic thermodynamic cycle inversion defrosting system:

When the temperature sensor located on the fluid circuit at the evaporator inlet detects an abnormal drop in
temperature, the regulator causes a 4-way valve to deviate the circulation of gas in the system as described below:
It should be noted that CLIMEXEL heat pumps will decrease the speed of rotation of the compressor and the fan in
order to decrease the frequency of defrosting phases.

The roles of the evaporator and condenser are reversed: The fluid brings calories to the fin heat exchanger to melt the
ice. The fan remains stopped while the system is defrosting. When the temperature detected by the sensor increases,
defrosting is finished and the 4-way valve switches back to the normal cycle.

II. Recommendations concerning safety and general operation

While the machine is running, some parts of the heat transfer fluid circuit can become very hot, and other
parts very cold. Access to the parts of the heat pump located behind the machine’s casing is reserved to qualified

professionals.

Never insert any object through the slots in the propeller grill.

Handling:

Handle the machine with care, never leave it lying on its side.

Electricity:

All wiring should be carried out by a qualified electrician in accordance with the rules of the art and, notably,
according to the standards in effect in the country of installation.

Before any intervention requiring removal of the access panel or involving manipulation of the hydraulic
connections, the heat pump must be disconnected from its power source: during installation, finish hydraulic

connections before wiring the machine in, disconnect the electricity before undoing the hydraulic connections.

Physical/ chemical properties of pool water :

Never start up the heat pump in winter if the pool water temperature has been allowed to fall to 5°C or
below (do not use the heat pump as a means to prevent the formation of ice on the surface of the pool).

Pool water treatment products currently available on the market are compatible with the materials used to
manufacture the heat pumps, it being assumed that the pool water's physical and chemical properties comply with
the following recommendations:

pH between 7 and 7.4
total hardness (TH) less than 190ppm
cyanuric acid content (stabiliser) less than 80 ppm
Concentration of free chlorine: 1.0 to 1.5 ppm
Concentration of free bromine: 1.0 to 1.5 ppm

These properties must be checked at the beginning of the season before allowing water to circulate through the
heat pump, and then at regular intervals throughout the season.

Caution:
Shock treatment (super chlorination) of the pool water: should it be necessary to carry out a shock treatment
of the pool water, isolate the hydraulic circuit (isolating valves) on which the heat pump is mounted before
beginning to increase the concentration of disinfectant, and wait until the concentration of disinfectant
returns to normal levels before re-opening these valves.

Minimising heat loss:

During the initial heating phase at the beginning of the season, cover the pool with an isothermal cover to limit heat
loss through water evaporation and thermal transfer between the pool water and the overlying air.
To render this phase as short as possible, the heat pump (and hence the filtration system) should be allowed to run
24 hours a day. After the initial heating phase, the pool should be left covered with an isothermal cover while the
pool is not in use, especially when the ambient temperature is cool (night, etc.).

III. Siting and installation

CLIMEXEL heat pumps must be installed outside at a distance of at least 3.5m from the pool in order to
comply with the standard C 15-100.

We recommend that the heat pump be installed on a support on the ground next to the pool plant room. The
installation site should meet the following criteria:

- easy accessibility around the machine to facilitate maintenance and cleaning;

- the heat pump is not directly exposed to prevailing winds, this is to limit splashing of the machine with water in the
event of precipitation. If necessary, install deflectors to protect the machine against this phenomenon taking care
not to obstruct the circulation of air into or out of the heat pump (minimum distances, see page 31).

29/96

2016/03 - Indice de révision : E - Code : 0033340

* Air flow rate at full fan power.
Each fan is fitted with a single phase 50 Hz 230 V fan.
Care should therefore be taken not to impede or restrict air circulation.
Respect the minimum distances (see the diagrams below) to be left between the various sides of the machine and
surrounding obstacles (walls, partitions, hedges, etc.).
The heat pump should be solidly fastened to a rigid support structure (concrete slab, etc.), the dimensions of which
should be at least equal to the machine's foot print.

CLIMEXEL heat pumps draw ambient air in through the evaporator and expel air out through the fan grill(s).
The nominal air flow rates are as follows:

Over time, the volume of condensates generated can be considerable if the air is humid. Water should never be
allowed to accumulate around the machine: if the condensates will not be absorbed or evacuated by the terrain,

a drain must be created.
Similarly, precipitation (rain, snow) and piles of dead leaves should not be allowed to accumulate under the

machine to the point where there reach the base of the machine: choose the site carefully and ensure that
the support provides enough elevation off the ground to prevent this risk in most situations.

To prevent water from accumulating on the evaporator and freezing during cold, wet weather, an awning may be
erected over the machine, ensure that there is a gap of at least 50 cm between the top of the machine and the
canopy.

To attenuate any vibrations, “silent-blocks” can be inserted under the feet of the machine before is it fixed in
position. (must be purchased separately).

The support should be very slightly sloped (a slope of 1 to 2% will suffice) towards the corner where the

condensate drainage hole is situated.

The condensate drain union is enclosed with the heat pump. It comprises a set of 6 plugs one of which is
perforated.

Cap the unnecessary holes on the outdoor unit (bottom) and
centralize the drainage when using a drain pipe.

The pipes, valves and unions constituting the by-pass loop should be made of high pressure (10 bar) PVC, diam­eter 50, glued. Allow the glue to dry properly before running water through the system.

In order to minimise the build-up of impurities in the filter and to minimise the risks of heat exchanger corrosion,

the by-pass tapping connections must be situated downstream from the filter and upstream of any system
injecting disinfectants or pH regulation chemicals into the pool water. The plant room throughwall flanges

should not be a source of vibration (noise), the PVC tubes should be fixed solidly in the walls or cushioned in a
material that absorbs vibrations.

Leave at least 1.5m of pipe between the by-pass return tapping point and the point at which any chemicals
are injected. Injection of any chemicals must be slaved to filtration. Make sure that the system cannot

accidentally siphon chemicals from the chemical buffer tanks while filtration is not running.

Caution:

Be careful not to allow impurities (stones, earth, etc.) into the pipes. These could form obstructions in the
titanium heat exchanger on start-up. In all cases, purge the circuit between the filter and the heat pump before

connecting the machine and starting filtration.

IV. Hydraulic connections

The heat pump features two screw type unions to allow the entry and exit of the pool water. The water inlet and
outlet lines should be glued to these unions.

These unions should be connected to a filtration by-pass loop, equipped with two isolating valves (one on the

inlet and one on the outlet) to allow isolation of the machine should it need to be removed. A third valve should
be installed on the main line between the by-pass tapping points to allow regulation of the flow rate.

The heat pump must be wired in by a qualified professional in accordance with the rules of the art.

The power supply must comply with the following table:

V.1 - Electrical panel side:

The line supplying the heat pump must be configured and fitted with one or more devices for:

- proper earthing of the machine

- protection of people by means of a 30 mA residual current device (interrupter or circuit breaker) dedicated to the
pool electric panel or specific to the heat pump line (unless the house is already equipped with one)

- protection of the machine against “overloads” and short-circuits by means of a thermal magnetic circuit-breaker

To avoid the untimely tripping of the circuit breakers on starting up the machine, use D curve circuit breakers.

V.2 - Heat pump side

The machine is wired in by means of the white connection box beside the information plate.

• Remove the protective casing from the heat exchanger.

• Withdraw the 4 plastic screws from the lid of the connection box to release and remove the lid.

• Feed the power cable into the box, pushing them up through the cable glands located in the bottom.

• Strip the 1 cm of each wire, and connect these to the domino, taking care to respect the live, neutral and earth

phases.

• Tighten the cable gland nuts to immobilise the cable and ensure that the seal around the cable is leak tight.

• Replace the lid and screws, then replace the heat exchanger casing.
