WATER CONNECTIONS
Connect the water supply (A) to the ½” male BSP float valve (6) using suitable piping with a cut-off valve (1).
We recommend the installation of a 0.5 mm light filter (2). The float valve can be regulated to set it to a range
of water supply pressures, as shown in figure 1 on this page.
WATER BASIN SUPPLY
Adjust the water level of the basin to between 3 cm below the level of the overflow by regulating the float valve.
Note: It is very important that the maximum temperature of the water supply of tank does not exceed the range
of 25-30 ° C since the performance of the saturation efficiency could be affected.
