12.2 A. Connection to the water supply.
•
Connect the water supply (A) to the ½” male BSP-M (6) using suitable piping with a cut-off valve (1). We
recommend the installation of a 0,5mm filter light (2).
•
In the HEF2 Series-DW, when the temperature of the feed water is below the dew point of the downstream
air flow after the wetting panel, FISAIR recommends to isolate the stainless steel manifold and pipes to
prevent possible condensations. To work according to hygienic certificate VDI6022 (ISO846) the isolations
should also meet that standards.
Remark
: How to avoid standing water in the water supply:
o
If the distance from the supply valve to the main water supply line (with continuous water
flow) ≥ 2m:
▪
Install a non-return valve before the cut-off valve.
▪
Install a 3-way valve, before the non-return valve, with a return line to the main
water supply line, to avoid water retention.
o
If the distance from the supply valve to the main water supply line (with continuous water
flow) <2m:
▪
Only the non-return valve is installed before the cut-off valve.
