.

2.3 Regulations and

provisions

•

The installation (water and electrical

installation) and first start-up, as well as the

maintenance of this unit may only be

carried out by an approved specialist

installer in accordance with these

Instructions.

•

Perfect function and operational safety are

only guaranteed with original accessories

and spare parts intended for the unit.

y

The installation should be carried out in

accordance with the relevant water

(WRAS) and electrical (IEE) guidelines and

regulations.

y

Installation should be carried out in

accordance with the relevant water and

electricity supply companys regulations.

The following are also to be respected:

Plastic pipe systems 

with the instantanous

water heater the operating temperature

can be adjusted upto max. 82 °C. The

maximum temperature can be limited to

65 °C. In case of failures temperatures can

rise up to 95 °C (max. 0.6 MPa).

The assigned plastic pipe system must be

appropriate for these conditions.

•

Electrical installation

– Electrical connection only with fixed-laid

leads in association with removable

cable bushings.

– The unit must be capable of all-pole

disconnection from the mains, for

example by fuses, with an isolating

distance of at least 3 mm.

2.5 Installation location

•

In an area not subject to the risk of

freezing.

•

Install close to the water tap.

2.6 Unit installation

E

•

Fit the suspension bracket.

Select the securing material to suit the

strength of the wall. With SH 120 S and

SH 150 S, two suspension brackets are

required.

Any unevenness in the wall is to be

compensated for by the spacer elements

provided (

a

. approx. 5 mm thick).

•

Install in a vertical position; see 

D

.

•

Push the cover caps onto the suspension

bracket 

E

  (

).

2.7 Water connection

•

Unvented (pressurized) for the

supply of several draw-off points.

– Install the type-tested safety groups 

F

 (order separately), also

possible in conjunction with 

KV 40

.

– Establish dimensions for the outflow pipe

for a fully-opened safety valve. The drain

aperture of the safety valve must remain

open to the atmosphere.

– The drain for the safety group is to be

installed with a constant downwards

inclination.

– The information provided in the

Installation Instructions for the safety

group are to be respected.

– Set a maximum flow rate of 18 l/min at

the choke of the safety group.

•

Vented (pressureless) for the supply

of one single draw-off point

The units are suitable for vented

(pressureless) operation mode.

Do not block off the drain and

fittings pivot arm.

– With this installation the Stiebel Eltron

fittings for vented wall-mounted water

heaters 

G

are to be used.

– Before connecting the fitting the water

pipe must be thoroughly flushed through.

– For use, installation, first start-up, and

maintenance, the same instructions apply

as for the operation of unvented

(pressurized) water heaters.

Instructions for „Signal anode in

unpressurized operating mode“

The display on the operating panel of the

signal anode for the pressurized water

heater provided as a standard fitting has no

function in the unpressurized operating

mode.

We recommend a conversion set with a

signal cartridge as display element in the

heating element space, Order No. 15 22 68.

The qualified installer can check the display

element of the signal anode after opening

the heating element space

Delivery status:

•

At temperatures of below - 15 ºC (e.g.

transportation/storage) the safety thermal

cut-out may trip. Press the reset button

( 

D 

 12

).

Handing over the unit:

Explain the function of the unit to the users

and familiarise them with its use.

Important notes:

•

Advise the users about possible hazards

(such as scalding).

•

Hand over these Operating and Installation

Instructions for safekeeping. All the

information provided in these Instructions

must be followed carefully. These

Instructions provide details about safety,

operation, installation, and the

maintenance of the unit.

2.12 Maintenance

•

When carrying out any work, disconnect

all poles from the mains supply.

•

Check the safety group regularly.

•

Descale the element only after

dismantling. Do not treat the reservoir

surface and parasitic current anode with

descaling agents.

•

•

Draining the storage water heater

cylinder: Before draining the cylinder,

disconnect the unit from the mains supply.

– Close the isolating valve in the cold

water feed line.

– Open the hot water fittings fully at all

draw-off points.

– Unscrew the cap from the drainage

nozzle (

D 

 10

).

Hot water may come out during

draining.

•

The corrosion protection resistor 

 J 

on

the insulating plate must not be damaged

or removed during servicing work. When

replacing the corrosion protection resistor

the assembly is to be re-established in the

correct manner.

•

Check the 

signal anode

 and replace it as

soon as the „SERVICE ANODE“ signal

lamp on the operating panel lights up.

When replacing the anode, it is essential

for the pressure switch to be screwed in

tight.

In unpressurized operating mode, the

signal cartridge is to be checked (see also

2.7, Water Connection, „Signal anode

instructions“). If the cartridge  

L 

 is

showing a red colour, the anode should

be checked and replaced if necessary.

Tightening torque: 1
