10.1 Water connection

Caution
!
Carry out all water connection and installation work in
accordance with local plumbing regulations.
The following material combinations are approved for metal pipe-
work installations:
Cold water inlet
Copper pipe
Steel pipe
Thoroughly flush the pipework before connecting the ap-
pliance. Foreign bodies, such as welding pearls, rust, sand
or sealant can impair the operational reliability of the
appliance.
Caution
!
To protect the stubs against corrosion the water tube con-
nection must be made with flat gaskets. The use of hemp
on stub threads is not permissible.
Safety valve
The appliance is a sealed unvented DHW tank. Provide the
appliance with a pressure relief valve.
Install a type-tested safety valve in the T&P port on the side
of the unit. The response pressure of the safety valve must be
below or equal to the permissible operating pressure of the
DHW tank.
The safety valve protects the appliance against unacceptable ex-
cess pressure.
Ensure that the expansion water escaping from the safety
valve can drip into a drain, e.g. a tank or sink.
Ensure the drain cannot be shut off.
Size the drain in a way that water can drain off unimpeded
when the safety valve is fully opened.
Ensure that the discharge pipe of the safety valve is open to
atmosphere.
Fit the discharge pipe of the safety valve with a constant
downward slope and in a room free from the risk of frost.
Pressure reducing valve
The maximum pressure in the cold water supply line must be at
least 20% below the response pressure the safety valve. If the
maximum pressure in the cold water supply line is higher, install
a pressure reducing valve.
Drain valve
Install a suitable drain valve at the lowest point in the cold
water inlet line.
