CONNECTION TO WATER SUPPLY
Input for cold water on the water heater is marked with blue
ring while hot water output is marked with a red ring, which is to
be respected when connecting water heater to water supply. The
models marked N are for installation above the fitting (pipe), while
P models are for installation below fitting (pipe) - see Picture 2 Low
capacity water heater works without pressure (open system) and it is
possible to use water only at one spot in the house.
The fittigns/mixing pipes appropriate for work without pres-
sure have to be used with this water heater – water inlet into the fit-
ting not over 3-4 mm diameter, and for low installation models, the
fitting should have 3 pipes. On the inlet pipe before the mixing unit
a non-return valve should be mounted to prevent tank to empty in
case of pressure fall in water supply pipeline.
