Safety instructions explained

!Please note

This symbol warns against the

risk of material losses and envi-

ronmental pollution.

Note

Details identified by the word "Note" con-

tain additional information.

Target group

These instructions are exclusively inten-

ded for qualified contractors.

■ Work on electrical equipment must

only be carried out by a qualified elec-

trician.

■ The system must be commissioned by

the system installer or a qualified per-

son authorised by the installer.

Regulations

Observe the following when working on

this system:

■ National installation requirements

■ Legal instructions regarding the pre-

vention of accidents

■ Legal instructions regarding environ-

mental protection

■ The Code of Practice of relevant trade

associations

■ All current safety regulations as

defined by DIN, EN, DVGW, VDE and

all locally applicable standards

aÖNORM, EN and ÖVE

cSEV, SUVA, SVTI and SWKI

Working on the system

■ Isolate the system from the power sup-

ply (e.g. by removing the separate fuse

or by means of a mains isolator) and

check that it is no longer 'live'.

■ Safeguard the system against unau-

thorised reconnection.

!Please note

Electronic assemblies can be

damaged by electrostatic dis-

charge.

Before beginning work, touch

earthed objects, such as heating

or water pipes, to discharge static

loads.

Repair work

!Please note

Repairing components that fulfil a

safety function can compromise

the safe operation of your sys-

tem.

Replace faulty components only

with original Viessmann spare

parts.

The appliance is only intended to be

installed and operated in sealed unven-

ted heating systems that comply with

EN 12828, with due attention paid to the

associated installation, service and

operating instructions. It is only designed

for the heating of water that is of potable

water quality.

Intended use presupposes that a fixed

installation in conjunction with permissi-

ble, system-specific components has

been carried out.

Commercial or industrial usage for a pur-

pose other than heating the building or

DHW shall be deemed inappropriate.

Any usage beyond this must be

approved by the manufacturer for the

individual case.

Incorrect usage or operation of the appli-

ance (e.g. the appliance being opened

by the system user) is prohibited and

results in an exclusion of liability. Incor-

rect usage also occurs if the components

in the heating system are modified from

their intended use (e.g. if the flue gas and

ventilation air paths are sealed).

Steps - commissioning, inspection and maintenance

5614 313 UAE

Commissioning the system

Operating instructions, service

instructions – control unit and

burner

1. Check that the installation room vent

is open.

2. Check the pre-charge pressure of the

expansion vessel.

If the pre-charge pressure of the

expansion vessel is lower than the

static system pressure, top up with

sufficient nitrogen to raise the pre-

charge pressure higher (0.1 to

0.2 bar/10 to 20 kPa) than the static

system pressure.

The static pressure corresponds to

the static head.

3. Open the check valves.

4. Fill the heating system with water and

vent it until the charge pressure is

higher (0.1 to 0.2 bar/10 to 20 kPa)

than the pre-charge pressure of the

expansion vessel (see page 18).

Permiss. operating pressure: 3 bar

(0.3 MPa)

Mark the charge pressure at pressure

gauge A.

6. Return the check valves to their oper-

ating position.

7. Open the oil shut-off valves.

Filling the heating system

Fill water

!Please note

Unsuitable fill water increases

the level of deposits and corro-

sion and may lead to boiler dam-

age.

■ Flush the heating system thor-

oughly before filling.

■ Only use fill water of potable

quality.

■ An antifreeze additive suitable

for heating systems can be

added to the fill water. The anti-

freeze manufacturer must ver-

ify its suitability.

■ Fill and top-up water with a

water hardness in excess of

the following values must be

softened, e.g. with a small soft-

ening system for heating water.
