3. INSTALLATION OF THE UNIT
The heater shall be placed in a technical equipment area (ventilated, dry and without stored pool
maintenance substances), close to the heat source (boiler, heat pump, geothermal energy, solar
heating...) and to the filter of the pool. It shall be fixed horizontally to the wall by means of 4 screws.

Dimensions in mm
If the heat source is far from the facility, plan to install the heat exchanger close to the heat source in
order to limit the losses of calories in the primary circuit. Plan the connection at the pool by ducts buried
in a trench at 50 cm depth, in Ø50 (or Ø 63 if the circuit is more than 30 metres there and back).
Notice: If the exchanger is far away from the heat source, provide the hydraulic connection with appropriate section
taking account of the distance, the flow rate and the pressure drop. In some cases, the circulating pump should be
replaced with a more powerful pump. In any case, these connections shall be properly insulated and fitted with
automatic air bleed on high points of the circuit.
4. CONNECTIONS
4.1 Hydraulic connections
Circuit to pool:
the exchanger shall be connected to the filtration circuit, with a minimum flow rate of
5m³/h up to 22m³/h. Plan for a by-pass fitting if the filter is above 22 m³/h or to facilitate the maintenance
of the appliance. Water inlet on the left or the right side by turning of the
exchanger/circulation
pump/valve
unit on the base.
Circuit to boiler:
the exchanger shall be connected directly to the primary circuit of the boiler supplying
constant temperature (90°C/70°C mandatory, maximum pressure 3 bars). On this circuit, with thermal
insulation includes, a circulation pump mounted on the exchanger and controlled by a digital regulation
thermostat.
Circulation direction:
circulation of both circuits shall be counter-current. Caution, pool water inlet shall
always be on the side of the thermo-well.
Tested pressure of hydraulic circuit: 4 bars
Service pressure of hydraulic circuit: 2 bars
