2.2 Provisions and specifica-
tion

The unit should not be operated

– in rooms at risk of explosion or fire from

chemicals, dust, gas or vapour,

– in the immediate vicinity of pipes or con-

tainers which transport or contain flam-
mable or explosive substances,

– if the minimum distances from adjacent

object surfaces are not observed.

In workshops or other rooms in which ex-
haust gases, oil or petrol vapours etc. occur
or where solvents and chemicals are used,
persistent odour problems and where appli-
cable contamination can occur.

• The unit may only be fitted to a vertical wall,

temperature­resistant up to at least 80 °C.

• Minimum distances from adjacent object

surfaces must be observed.

• All electrical connection and installation

work must be performed to VDE regula­
tions (0100), the regulations of a competent
utility company and the corresponding na­
tional and regional regulations.

For regular maintenance we recommend
checking the control and adjustment elements.

At the latest 10 years after first use, the safety,
control and adjustment elements should be
checked by an expert.

• The unit must not be mounted directly be­

low a wall socket.

• If the unit is permanently connected to an

AC network (junction box) an isolation
distance of at least 3mm is required on all
poles for isolation from the network. For
this circuit breakers, LS switches, fuses etc.
can be used.

Installation with permanent connection ca­

bles is not permitted.

• The rating plate must be observed. The rat­

ed voltage must correspond to the nominal
voltage.

• On installation of the heater in rooms with

a bath and/or shower, the protection area
to VDE 0100 part 701 as specified on the
unit rating plate must be observed.

a person in the bath or shower.

replaced with original Stiebel Eltron spare

2.3 Installation

2.3.1 Installation of wall bracket

B

The wall bracket should be used as a template
for fixing the appliance to the wall. It also helps
to keep the necessary ground clearance. To at­
tach the unit proceed as follows:

I

Place the wall bracket (5) holding the

centre point horizontally on the ground and
mark the holes a and d on the assembly wall;

II

Raise the wall bracket so that the ho­

les b in the wall bracket coincide with the
marks just made on the assembly wall;

Mark holes c and d on the wall bracket on

the assembly wall;

At all four markings drill holes and attach

the wall bracket to the wall using suitable
fixing materials (wall plugs and screws) de­
pendig on the type of wall. The vertical slots
allow adjustment for an offset in the fixing
holes.

2.3.2 Unit installation

C

The convector is mounted by attaching the
slots on the rear simultaneously to the four
tabs of the wall bracket pressing down to lock.
The closing bolt (6) of the wall bracket is then
turned clockwise to the stop, locking the fixing.
To remove the convector, unscrew the locking
bolt and lift the unit slightly, pulling it forwards
and out of the bracket.

2.4 Electrical connection

The required electrical connection is AC 30V
~ 50 Hz.
For fixed connection, an earth socket or junc­
tion box should be installed at a distance of at
least 10 cm to the side of the heater.

2.5 Handover

Explain to the user how the unit functions.
Draw his attention in particular to the safety
instructions.
Give the user these operating and usage in­
structions.

Chechk that . . .
. . . the ON/OFF switch is turned on.
. . . in your fuse box, the corresponding fuse is intact or whether the breaker has tripped.
Eliminate cause!
If the heater still does not warm up, call an engineer!

Check whether it is covered, so it could have overheated (e.g. covered air outlet or inlet opening).
Eliminate cause!

If it does not warm up again after a few minutes‘ cooling down period, call an engineer!

Read the type (Typ) and number (Nr.) from the rating plate (8)
on the unit and tell customer service!
