3. INSTALLATION OF THE UNIT

The heater shall be be placed in a technical equipment area (ventilated, dry and without stored pool
maintenance substances), close to the filter of the pool. It shall be fixed to the wall by means of 4 screws
(see points of fixing on back sight §2.2).

4. CONNECTIONS

4.1 Hydraulic connections

The electric heater shall be connected in line to the return circuit downstream the filtration process, 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.
1/2 unions (Ø50 female inside and Ø63 male outside) are designed to make a connection with the
filtering circuit with a Ø50 or Ø63 PVC pipe.
Warning:
with a Ø63 pool circuit, to connect the device, provide a sleeve (Ø63 inside).
Advised fitting: if possible, the heater connection should be carried out so that it is on load as
compared with the filtration system or the pool.
Direction of circulation: the heater is arranged for water circulation from left to right. If necessary,
reverse the direction of circulation by making the following changes:
- reverse the digital regulation thermostat and safety thermostat sensors. The regulation thermostat
sensor must be at the heater input and the safety sensor at the output.
- turn the 2 elbows + flow switch unit by half a turn:
- Test pressure: 4 bars
The heater shall be installed before any water treatment system
