4. CONNECTIONS

4.1 Hydraulic connections

Circuit to pool: the heat exchanger shall be connected from a by-pass onto the filtration circuit
upstream any disinfection process. Inlet of water on the bottom, outlet on the top shall be respected.
Circuit to boiler: the exchanger shall be connected directly to the primary circuit of the boiler supplying
constant temperature (90°C/70°C mandatory). Install automatic air-bleed on high points of primary
circuit.
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: 5 bars.

Caution ! Connection of primary shall be performed before any other
Warning! Inhibit any 90° PVC elbow fitted directly at the exit of the exchanger. Leave at
least 25 cm of straight tubing to avoid any knocking of the flow rate controller pallet.

4.2 Electric connections

• The single-phase electrical supply (230V-50Hz) of the exchanger must come from a protection and
switching device (not supplied) complying with the standards and regulations in force in the country
where it is installed (in France, refer to standard NF C 15100).
• use the supply cable delivered with the appliance: 2 poles + Earth 10/16 A in 3G1 (section 1 mm²).
Do not admit any long extension or multisocket connection.
Remark: Plan for a socket to connect the supply cable delivered with the appliance.
• Electrical protection: this current socket must have a 5 A fuse switch with, upstream, a 30 mA
differential circuit breaker (calibre > than 5 A), or an independent 30 mA circuit breaker (calibre 5 A)
upstream.
• use a 3G1 wire (1 mm² section) if you wish to control a complementary pump (fig. 1), an electric
valve (fig. 2 and 3) or a boiler (fig. 4) to provide power to the primary circuit of the exchanger. This
function is carried out via the dry contact without polarity "normally open at rest" (Imax 5A at 250 Vac
50-60hZ) available on the regulator terminals 19-20.
Service pressure of hydraulic circuit: 2 bars.
