1. Operating instructions for the user and the qualied installer
Description
The EVS 15-150 unvented (pressur-
ized) wall-mounted water heater can
heat potable water up to about:
EVS 15-150 = 75°C to suit demand
and supply a number of draw-off
points. The water content is automatically
heated to the preset temperature.
The device is adjusted at the works to
75°C.
In brief
• Contains 15 - 150 l domestic hot
water with up to 75 °C
• Pressurized enamelled steel
container
• Non fluorine polyurethane
insulation layer
Important notes:
High temperatures present
the risk of scalding.
– Arrange to have the wall-mounted
water heater and the safety valve
or safety group checked regularly
by a qualified installer.
– Check the fittings regularly; clean
limescale off outlets using
conventional commercial descaling
products.
Disconnection from the
supply mains having a contact
separation in all poles that provide
full disconnection at least 3 mm.
The device is under water
pressure. During heating,
water will drip from the safety valve
for reasons of safety; if dripping
continues after heating-up has
concluded, contact your installer.
Risk of freezing
The device is protected against freez-
ing at every temperature setting,
but not the safety valve or the safety
group and the water pipe.
Temperature adjustment
EVS 15 - 150
The temperature adjustment may be
altered by the user directly at the
temperature knob.
Care
A damp cloth is all that is needed for
care and cleaning the outer housing.
Do not use any foaming or caustic
cleaning agents.
Instructions for use and installation
Keep these instructions in a
safe place, and give them to
the new owner if you move house; if
maintanace or repair work is required,
let the qualified installer have them
for reference.
Use only original Stiebel
Eltron spare parts

– Install the device Fig. E
When installing the device, select
securing materials to suit the stability
of the wall. The wall must be able to
carry at least two times of the weight
of the unit filled with water. Please
make sure that the dowels are
tightened in the wall by turning the
dowels clockwise and are in an upward
position before hanging the unit.
2. Installation instructions for the qualied installer
Water connection Fig. F,G
Unvented (pressurized) for the supply
of several draw-off points.
For indoor installation only
A safety valve must be fitted
at the cold water inlet of the
unit, by a skilled installer.
Note with regard to copper
pipes: No connections made
of copper may be installed directly on
the device. We recommend that red
brass or plastic transition fittings be
used as connection isolators for the
pipe connections.

2. Installation instructions for the qualied installer
Electrical connection A
Electrical connection may
only be carried out by a
qualified installer, in accordance with
these instructions.
The device is intended for fixed
connection to AC mains supplies
using permanently-laid connection
leads.
Specific national regulations are to be
respected.
First fill the device completely
with water, then connect the
current supply. The device may not be
taken into operation without water
filling (see also First start-up).
A discharge pipe connected
to the pressure-relief device
is to be installed in a continuously
downward direction and in a frost-
free environment.
First start-up
Only to be carried out by a qualified
installer, in accordance with these
instructions.
– Before switching on, fill
the device by opening the
hot water valve and flush it through
thoroughly.
– Monitor first heating; check
to ensure that the thermo-
stat switches off.
– Check the safety valve or
safety group for functional
reliability.
– The draining pipe must be
kept sloping downwards
and connected to the pressure
release hole at the safety valve.
The water may drip from the
discharge pipe of the pressure-
relief device and that this pipe must
be left open to the atmosphere.
The pressure-relief device is
to be operated regularly to
remove lime deposists and to verify
that it is not blocked.
If the supply cord is damaged,
it must be replaced by the
manufacturer, its service agent or
similarly qualified presons in order to
avoid a hazard.
How the appliance is to be
fixed to its support. The
method of fixing stated is not to
depend on the use of adhesives since
they are not considered to be a reli-
able fixing means.

next inspection is necessary.
– Carry out descaling of the device
only after removing the heating
element. Do not treat the surface of
the tank with descaling agents.
– In the event of the thermal cut-out
having operated (no through-flow),
replace the regulator/limiters
combination.
– Check the safety valve or safety
group regularly.
Draining the cylinder
Draining can be carried out via the
safety valve.
Before draining the device,
disconnect the device from
the electricity supply!
– Close the isolating valve in the cold
water pipe.
– Open all hot water valves fully at all
draw-off points.
– Open safety valve.
Hot water may emerge
during draining.
