It is advisable to place the appliance near the main hot water drawing
point in order to avoid heat loss along the piping, and possibly
near a drain to facilitate emptying operations.
The procedure for correct installation is illustrated below (See also fig
3.2)
Water safety unit (Mandatory).
It is mandatory to install a water safety unit (not supplied by us,
except safety valve)
which must comprise at least the following elements:
Stopcock or stop valve; (not supplied)
-
Safety and non return valve; (supplied)
-
Water pressure control valve. (Not supplied)
-
Electrolyte Sleeves (Supplied)
-
The above-mentioned components are necessary for safe operation
of the Appliances supplied. The rated pressure setting of the water
safety valve must be 0.85Mpa (8.5bar). When installing the water
safety unit make sure not to force or tamper with it. Water may drip
from the water safety valve discharge connection. This opening must
be left open to the atmosphere. A downward sloping drain pipe must
be arranged in a place free of condensate and ice. To avoid
overpressures make sure the piping is free of any obstructions.
