4. CONNECTIONS

4.1 Hydraulic connections

Circuit to pool: the exchanger shall be connected to the filtering circuit via a by-pass (preferably, or
absolutely if the filter flow rate is more than 22 m³/h). Water inlet on the left or the right side by turning
housing 180° and inversion of circulation pump and one-way valve (see sketch below).
Circuit to boiler: the exchanger shall be connected directly to the primary circuit of the boiler supplying
constant temperature (90°C/70°C mandatory). On that circuit, the circulation pump is controlled by the
thermostat and shall be connected to the filtration pump to allow heating only when filtration is running.
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: 4 bars
To reverse direction of circulation:
1- remove hood of electric box,
2- disconnect both connectors of the regulator to release hood,
3- remove the 4 screws fixing the hood to the body,
4- reverse the body of the exchanger, reverse the circulating pump,
5- fix the electric box to the body by means of the 4 screws (see picture below),
6- connect both connectors to the "Bazic" regulator,
7- fix the hood.
Service pressure of hydraulic circuit: 2 bars
WARNING!
To be in this configuration,
the body has pivoted by 180°
(without having removed the
flow rate controller and the
glove finger of the regulation
probe).
