HYDRAULIC CONNECTIONS:

– Water quality necessary for this device: NF-EN-16713-3

– The HP is compatible with all types of water treatment. The HP must imperatively be connected by a PVC pipe of Ø 50mm to the swimming pool’s hydraulic

circuit, after the lter and before the treatment system, regardless of its type (Cl, pH, Br metering pumps and/or electrolyser).

– Follow the hydraulic connection order (blue = water in, red = water out)

– A bypass must be installed to facilitate work on the HP.

– Before connecting the PVC pipes to the HP, make sure the circuit is clean of any work residue (stone, soil, etc.).

Connection of the condensate evacuation pack:

During operations, the HP is subject to a condensation phenomenon. This translates into a water ow, which can be more or less important depending on the

degree of humidity. To channel this ow, which can represent several litres of water per day, we recommend you install the provided condensate evacuation pack

and connect it to a suitable water evacuation circuit.

ELECTRICAL CONNECTIONS:

Connection of the power supply:

– Prior to undertaking any intervention inside the HP, it is imperative to disconnect the power supply from the HP: there is a risk of electrocution that can cause

damages, severe injuries, and even death.

– Only a certied and experienced technician is authorised to conduct cabling work in an HP or to replace the power cable.

– The power supply should match the voltage featuring on the information plate of the HP.

– The HP must be connected to an earthing connection.

Electric installation:

To ensure safe operations and to protect the integrity of your electric installation, the HP should be connected to the electrical mains according to the following

rules:

Upstream, the electrical mains should be protected by a 30-mA differential switch.

The HP should be connected to a suitable class C circuit-breaker (see the table below) according to the standards and regulations in force in the country where

the system is installed.

The power cord should be adapted to the power of the HP and the length of cable required for the installation (see the table below). The cable must be suitable for

outdoor use.

In the case of a three-phase system, it is imperative to follow the connection order of the phases.

If phases are inverted, the compressor of the HP will not work.

In public spaces, the installation of an emergency stop button close to the HP is mandatory.

The voltage must match the voltage mentioned on the HP.

The connections must be sized based on the power of the HP and on the installation state.

Models Power supply Max current Diameter of the RO2V cable

and maximum cable length Magnetic-thermal protection (C)

– Use the cable-gland and the pass-through provided inside the HP for the passage of the cables.

– As the HP is installed outdoors, the cable must pass through a protection sheath provided for that purpose. The power supply of the HP must be provided with a

protection system according to applicable law.

– The electric cables must be buried at a depth of 50 cm (85 cm under a road or a path) in an electric sheath (ringed and red). When a buried sheathed cable

intersects with another cable or a duct (water, gas...), the distance between the two must be greater than 20 cm.

ELECTRICAL CONNECTIONS:

IMMERSION AND STARTING THE HP AT THE BEGINNING OF THE SEASON:

USE

Heating priority:

The ltration pump can be connected to the HP to force the ltration to operate if the water is not at the desired temperature.

Prior to this connection, a “dry contact” (normally open relay or connector) with a 230V AC coil should be provided.

Electrical connections:

– Connect the coil of this relay (A1 and A2) on the P1 and P2 terminals of the HP.

– Connect the input and the output of the dry contact (normally open) in parallel with the dry contact of the ltration clock of the swimming pool.

– Cover the pool with a cover (bubble cover, shutter...) to reduce heat losses.

Once the HP is connected to the water circuit with the bypass, and is connected to the power supply by a professional, ensure that:

– The HP is horizontal (level).

– The HP is secured and stable.

– The water circuit has been purged of air that has been trapped in the piping of the HP.

– The pressure gauge, at the back of the HP, shows a temperature that is equal to the ambient outdoor temperature.

– The water circuit is properly connected (no leaks or damage to the hydraulic connections, the connections are properly tightened).

– The electric circuit is properly connected (the cables are tightly secured to the terminals and intermediate circuit-breaker), properly insulated, and connected to

the earthing connection.

– The conditions of installation and use described above have all been met.

– The outdoor temperature is between 0 and +35°C.

– The water temperature is of 15°C minimum.

– The evaporator at the rear/on the sides of the HP is clean (leaves, dust, pollen, cobwebs...)

You can now start your device by following, in the given order, the following steps:

– Open the 3 valves of the bypass (refer to the hydraulic diagram).

– Half-close the bypass valve.

– Remove all unused items or tools from the area surrounding the HP.

– Start the pump of the ltration system.

– Power up the HP by engaging the circuit-breaker and using the ON/OFF button of the display.

– Check that the HP starts and stops in sync with the ltration circuit: if no water is detected in the HP, the display shows “FLO”

– The HP starts after a delay of a few minutes.

– Adjust the temperature (“Regulation” chapter).

– Adjust the water ow (“Water ow setting” chapter).

– After a few minutes, you can adjust the bypass valve as indicated in the “Water ow setting” chapter. Having completed the above steps, cover the pool and let

the HP operate for a few days with the ltration pump in “forced mode” until the water of the pool reaches the desired bathing temperature.

Parameter for taking the connection into account:

Check that the setting of the ltration pump parameter

(parameter #9) is set to “1”. If this is not the case, please

SETTINGS:

GENERAL USE:

Water ow setting:

– To optimise the heating performance and achieve power savings, the ow of water travelling through the HP should be adjusted.

– The adjustment is done based on the reading of the adjustment pressure gauge. The adjustment is done by opening or closing the adjustment valve of the

bypass.

– To increase the pressure on the front pressure gauge: reduce the amount of water passing through the HP: open the bypass adjustment valve.

– To reduce the pressure on the front pressure gauge: increase the amount of water passing through the HP: close the bypass adjustment valve.

– During normal operations, the inlet and outlet valves must remain fully open.

Normal pressure:

– The ow of water through the HP and the uid pressure in the device are intimately linked.

– The ow value given for information purposes is of 5 to 7m³/h, i.e. approximately 100l/min to reach the maximum heating power of the HP.

– The ideal setting is achieved when the hand of the pressure gauge (for heating operations in boost or Hi mode) indicates a temperature in °C greater by 10 to

15°C than the current temperature of the swimming pool.

– Remember, the HP must operate for a few minutes before the pressure stabilises on the pressure gauge.

– Example: the swimming pool water is 20°C, the HP has been operating for 5 minutes, and the hand of the pressure gauge indicates 20 bars / 280 PSI / 32°C /

90°F. -> 32°C – 20°C = 12°C -> the setting is right (between 10 and 15°C).

Abnormal pressure:

– If the pressure at the pressure gauge is too high or too low, that means that the ow of water through the HP is inadequate.

– Action must therefore be taken by opening or closing progressively the bypass adjustment valve, to get the pressure in the recommended range.

– When stopped, the temperature reading should be close to the temperature of the swimming pool water.

– If the hand shows 0, the device should not be used (contact your distributor).

Setting frequency:

– The ow through the HP depends much on water temperature, and to a lesser extent, on air temperature.

It should therefore be adjusted:

– When the pump is started, and the water is cold

– During the rise of temperature

– When the desired temperature has been reached.

There should not be any reason to subsequently adjust the ow. An occasional reading of the pressure gauge to ensure everything is operating normally and the

ow remains unchanged is generally sucient.

Water quality (standard):

– The recommended water quality must comply with the following standards.

– Chlorine concentration less than 2.5 ppm

– pH between 6.9 and 8

– In case of sudden chlorination, isolate the heat pump by shutting the inlet and outlet valves of the device, and reset them to their initial positions after

treatment.

Maintaining the temperature:

– Once the desired temperature has been reached, you can set the daily ltration time according to your habits (8 to 10 hours per day minimum during the sea-

son). The heat pump will start automatically whenever necessary. The minimum operating time varies based on the time of use, please contact your distributor

for further information.

If you notice the water temperature of the pool is falling, despite the device operating continuously, increase the daily ltration time.

Do not forget to cover the pool with an insulated cover when you are not using it, to limit heat losses.

IMPORTANT: a swimming pool without a cover will lose 4 times more energy than the same pool with a cover.

The choice of the heat pump should always take into account the presence of a tarpaulin, a rolling shutter, or any other type of protection of the pool when it is

not being used.
