Installation
Mounting
It is recommended that the water heater is installed in
a room with existing floor drainage.
Install the base frame as illustrated.
M8 screws and nuts are supplied.
The water heater must be installed horizontally on the
base frame (UL4) and can be aligned using the adjustable
feet (UL1).
The water heater is rotated in the base frame so that the
arrow on the "NOTE" sign points straight up.
When installing, ensure that there is sufficient space for
removing the thermostat or immersion heater in front
of the junction box (approx. 500 mm).
Pipe installation
NOTE
Pipe installation must be carried out in accord-
ance with current norms and directives.
The water heater is supplied with compression ring
couplings for copper or plastic pipes. Internal support
bushes must be fitted when a plastic or annealed copper
pipe is used.
An overflow pipe must be routed from the safety valve
to a suitable drain. The dimension of the overflow pipe
must be the same as the safety valve's (Ø 15 mm). The
pipe must be routed to prevent water pockets, and be
frost-proof and well supported.
If uncertain, contact a plumber alternatively see applic-
able standards.
Filling
The water heater must be filled with water before the
mains supply is switched on. Filling takes place as follows:
■
Check that the vent screw (QM5) is tightened.
■
Check that the safety valve (FL1) is closed.
■
Open the shut off valve by turning the knob (QM35)
anti-clockwise .
■
Bleed the water heater by opening a hot water tap in
the system. This can be closed when only water comes
out of the tap. The water heater is now filled and the
power can be switched on.
Setting the mixer valve
Increase/decrease the tap water temperature by turning
the mixer valve knob (FQ1) anti-clockwise/clockwise.
Setting range approx. 40 – 65 °C.
