These domestic hot water tanks can operate at a maximum operating
pressure of 10 bars. The recommended operating pressure is under
7 bar.
nSpecific precautions
Before making the connection, rinse the drinking water inlet
pipes in order not to introduce metal or other particles into the
appliance's tank.
nProvision for Switzerland
Make the connections according to the instructions of the Société
Suisse de l'Industrie du Gaz et des Eaux. Comply with local
instructions from water distribution plants.
nSafety valve
CAUTION
In compliance with the safety rules, fit a sealed safety
valve to the domestic cold water tank inlet.
France: We recommend NF-marked hydraulic membrance safety
control units.
4Integrate the safety valve in the cold water circuit.
4Install the safety valve close to the tank in a place which is easy
to access.
nSize
The safety device and its connection to the DHW tank must be of at
least the same diameter as the domestic cold water supply pipe of
the tank domestic circuit.
There must be no cut-off element between the valve or the safety unit
and the domestic hot water tank.
The safety device drain pipe must have a uniform and sufficient
gradient and its diameter must be at least equal to that of the outlet
opening of the safety device (to prevent the flow of water being
hindered if the pressure is too high).
The outlet pipe in the valve or safety assembly must not be blocked.
Germany: Define the dimensions of the safety valve in accordance
with the DIN 1988 standard.

servicing.
160 SL 4. Installation
15/03/2012 - 300026901-001-C 16

Install a drainage valve at the lowest point on the tank.
nIsolating valves
Hydraulically isolate the primary and secondary circuits using stop
valves to facilitate maintenance operations on the unit. The valves
make it possible to carry out maintenance on the tank and its
components without draining the entire installation.
These valves are also used to isolate the tank unit when conducting
a pressurised check on the leak tightness of the installation if the test
pressure is greater than the admissible operating pressure.
CAUTION
If the mains pipes are made of copper, fit a sleeve made
of steel, cast iron or any other insulating material between
the tank's hot water outlet and the pipes to prevent
corrosion to the connection.
nConnecting the domestic cold water
Make the connection to the cold water supply according to the
hydraulic installation diagram.
¼ Refer to the installation and maintenance instructions of the
boiler
Install a water drain in the boiler room and a funnel-siphon for the
safety unit.
The components used for the connection to the cold water supply
must comply with the prevailing standards and regulations in the
country concerned. Fit a one-way valve to the domestic cold water
circuit.
Make the connection to the cold water supply according to the
hydraulic installation diagram. ¼ Refer to the installation and

safety unit.
The components used for the connection to the cold water supply
must comply with the prevailing standards and regulations in the
country concerned. Fit a one-way valve to the domestic cold water
circuit.
nPressure reducer
If the mains pressure exceeds 80% of the valve or safety unit setpoint
(e.g.: 5.5 bar for a safety unit set at 7 bar), a pressure reducer must
be fitted upstream of the appliance. Install the pressure reducer
downstream the water meter in such a way as to ensure the same
pressure in all of the installation pipes.
nMeasures to take to prevent hot water flow reversal
Fit a one-way valve to the domestic cold water circuit.
