Working on the system

■ When using gas as fuel, also close the

main gas shut-off valve and safeguard

against unauthorised reopening.

■ Isolate the system from the power sup-

ply and check that it is no longer 'live',

e.g. by removing a separate fuse or by

means of a main isolator.

■ Safeguard the system against unau-

thorised reconnection.

!Please note

Electronic modules can be dam-

aged by electrostatic dis-

charges.

Touch earthed objects, such as

Installation

Installation information

!Please note

To prevent material losses, install

the combi cylinder in a draught-

free room free from the risk of

frost.

Otherwise the combi cylinder will

have to be drained if there is a risk

of frost and it is not in use.

!Please note

The thermal insulation must not

be able to come into contact with

naked flames.

Exercise caution when welding

and soldering.

Provide adequate clearance from the

wall so that the thermostat can be oper-

ated (if installed).

sion heater

Maintain minimum clearance in front of

the cylinder.

Note

The unheated length of any threaded

immersion heater installed on site must

be at least 100 mm.

■ For connecting on the DHW side,

observe DIN 1988 and DIN 4753.

■ Connect all pipework with detachable

fittings.

■ Seal connections that are not required

with red brass caps.

Information regarding the safety

valve

The system must be equipped with a

type-tested diaphragm safety valve as

protection against overpressure.

Permiss. operating pressure: 10 bar.

The connection diameter of the safety

valve must be R ¾ (DN 20).

Consequently, the max. permissible

heat input would be 150 kW. If the heat

input of the Vitocell exceeds 150 kW,

select a larger safety valve that is able to

cope with the respective heat input (see

DIN 4753-1, issue 3/88, section 6.3.1).

Install the safety valve in the cold water

pipe. It must not be able to be isolated

from the DHW cylinder.

The pipework between the safety valve

and the DHW cylinder must not be

restricted in any way.

The safety valve discharge pipe must not

be able to be closed. Expelled water

should be safely and visibly drained into

a sewer. Place a sign close to the safety

valve discharge pipe or on the safety

valve itself with the following inscription:

"For safety reasons, water may be dis-

charged from the discharge pipe during

heating. Never seal off!"

Install the safety valve above the top

edge of the DHW cylinder.

Connecting the heating water side

■ Adjust the thermostat and high limit

safety cut-out so that the DHW tem-

perature in the cylinder never exceeds

95 ºC.

■ Connect all pipework with detachable

fittings.

Permissible temperatures

on the solar side: 140 °C

on the heating water side: 110 °C

Permissible operating pressure

on the solar side: 10 bar

on the heating water side: 3 bar

Test pressure

on the solar side: 16 bar

on the heating water side: 4.8 bar

1. Install the flow pipes with an incline

and fit an air vent valve at the highest

point.

2. Install control equipment that

ensures the permissible tempera-

tures on the heating side are main-

tained.

3. Install an additional type-tested high

limit safety cut-out, if none has been

installed so far in the system. For this,

use a twin thermostat (temperature

limiter and high limit safety cut-out).

4. Seal all unused connections with

plugs or caps.
