Installation
Mounting
It is recommended that the water heater is installed in
a room with existing floor drainage.
The copper-lined water heater must be installed upright
and can be aligned using the adjustable feet (UL1).
When installing, ensure that there is sufficient space for
removing the thermostat or immersion heater in front
of the junction box (approx. 400 mm).
Enclosed kit
Safety valve
Reduction from Ø 28 mm to
Ø 22 mm.
Insulation plug
Cover discs, 3 x
Removing the insulation
NOTE
Only applies to ES24 - 500
ES24 - 500 can be made less bulky upon installation by
removing the insulation (water heater diameter without
insulation is Ø 650).
1.
Remove the electrical
cover and electrical pan-
el.
2.
Loosen the screws along
the joining plate on both
jacket halves.
3.
Remove the drain valve.
4.
Lift off the top cover.
5.
Pull the insulated jacket
halves straight off.
Carry out assembly in reverse order. If the screws are
difficult to fit in the old holes, the joining plate can be
turned upside down, which produces new holes in the
insulated jacket halves.
Finally, fit the enclosed cover discs on each connection,
by pressing them over the connections.
Once the water heater is in the required position, remove
the lifting device from the top and fit the enclosed insu-
lation plug in the hole left by the lifting eye (XR1).

Pipe installation
NOTE
Fit the cover discs before the pipe installation is
made.
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.
ES24 - 300 is supplied with a reduction kit from Ø 28 mm
to Ø 22 mm, which can be used if the hot water heater
is installed where a Ø 22 pipe already exists or is required.
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.
The following equipment must be installed on the cold
water pipe:
QM35 Shut-off valve
RM1 Non-return valve
FL1 Safety valve (supplied)
FL6 Vacuum valve
FQ1 Mixer valve (if the tap water temperature exceeds
65 °C)
If uncertain, contact a plumber alternatively see applic-
able standards.
When the water heater is installed without a mixer 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 relevant directions
for the application.
Filling
The water heater must be filled with water before the
mains supply is switched on. Filling takes place as follows:
Check that the safety valve (FL1) is closed.
Check that the drainage valve (QM3) 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. 50 – 65 °C.
