Mounting
It is recommended that the water heater is installed in a
room with existing floor drainage. The water heater can
be mounted hanging vertically on a flat surface (with
the connections downward) or lying horizontally (with
the reverse down).
Use the supplied suspension brackets (12) when hanging
on a wall, these are secured first (Ø8 – 10 mm screws),
see the figure below. The water heater is then mounted
on the bracket. The water heater can now be slid side-
ways to some extent, which facilitates the fitting of the
pipes.
For further fastening, the enclosed securing bracket (13)
is fitted on the wall against the top of the water heater
as a tip guard, see the figure below.
An area of 200 mm is required in front of/under the wa-
ter heater for service work.
* EMINENT-E requires free space behind /above tthe wa-
ter heater for inspection of the sacrificial anode (40).
See the section "Care and maintenance - Sacrificial
anode".

Pipe installation
The water heater is equipped for compression ring cou-
plings for copper or plastic pipes. Internal support bush-
es should be fitted when a plastic or annealed copper
pipe is used.
All necessary valve equipment: shut-off/non-return
valve, safety/drain valve and the mixing valve installed
on delivery.
An overflow pipe should be routed from the safety valve
to an appropriate drain. The dimension of the overflow
pipe must be the same as the safety valve's, (Ø15 mm),
the pipe must be routed to prevent water pockets, and
be frost-proof and well supported.
If uncertain contact pipe installer alternatively see appli-
cable standards.
If the hot water heater is installed without a mixing
valve, the thermostat setting must be such that the tap
water temperature does not exceed 65 °C. Should a
higher temperature be required, follow the applicable
directions.
Filling
The water heater must be filled with water before the
mains supply is switched on. Filling takes place as fol-
lows:
1
Check that the bleed screw°(45) is tightened.
2
Check that the safety/drainage valve (23) is
closed.
3
Open the shut off valve by turning the knob
(22) anti-clockwise .
4
Bleed the water heater by opening a hot water
tap in the system. When only water comes out
of the tap this can be closed.
The water heater is now filled and the power can be
switched on.
Setting the mixing valve
Increase/decrease the tap water temperature by turning
the mixing valve knob (25) anti-clockwise/clockwise.
Setting range approx. 50 – 65°C.
