Water pipe routing
Produce connection (16) for the cold water supply between
safety /drain valve (14) and elbow (13) - lower pipe on the
water heater.
Route the hot water pipe (22) from the elbow with the inter
grated breather valve to the hot water consumers.
System installation
Installation of the safety temperature and pressure
valve
The safety temperature and pressure valve come factory pre-
fitted on the water heater
All pressure and submergible water pumps be used for
operating the water heater.
In order to guarantee complete emptying of the water
content and to prevent pressure greater than 450 kPa
occurring in the water heater, the safety temperature
and safety valve MUST be used.
The supplied water connectors safety drain valve have a 12
mm rigid piping connection (e.g. John Guest system). For
connecting to rigid pipes with other diameters appropriate
adapter must be used.
Route the pipes so that they are as short and free of
kinks as possible (hose connections must be secured
using hose clamps - also for cold water! - pressure of
up to 300 kPa can occur in the T&P safety valve - also with
the submergible pumps - because of the heat of the water
and resulting expansion.
All hot water pipes should be routed in a descending
manner to the safety valve ! otherwise no guarantee of
frost protection
