Safety instructions explained

Danger

This symbol warns against the

risk of injury.

!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 the refrigerant circuit may

only be carried out by authorised

refrigeration engineers.

■ 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 regulations

■ Statutory regulations regarding the

prevention of accidents

■ Statutory regulations regarding envi-

ronmental protection

■ Codes of practice of the 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, SWKI and

SVGW

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'.

Note

In addition to the control circuit, there

may be several power circuits.

Danger

Contact with 'live' components

can result in severe injuries.

Some components on the

PCBs will remain 'live' even

after the power supply has

been switched off.

Prior to removing equipment

covers, wait at least 4 min. to

allow the voltage to dissipate.

■ Safeguard the system against recon-

nection.

Safety instructions

5782 176 GB

!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.

Defective components must be

replaced with genuine

Viessmann spare parts.

Auxiliary components, spare and

wearing parts

!Please note

Spare and wearing parts that

have not been tested together

with the system can compromise

its function. Installing non-author-

ised components and making

non-approved modifications or

conversions can compromise

safety and may invalidate our

warranty.

For replacements, use only spare

parts supplied or approved by

Viessmann.

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.

Depending on the version, the appliance

can only be used for the following pur-

poses:

■ Central heating

■ Central cooling

■ DHW heating

The range of functions can be extended

with additional components and acces-

sories.

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 central heating/cooling

or DHW heating shall be deemed inap-

propriate.

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 function.

Note

The appliance is intended exclusively for

domestic use, i.e. even users who have

not had any instruction are able to oper-

ate the appliance safely.

Installation

!Please note

Avoid damaging the appliance

during transport.

Never put weight on top of the

appliance.

!Please note

If the compressor in the external

unit is strongly tilted, lubricant will

enter the refrigerant circuit and

damage the appliance.

Note the max. tilting angle of

45°.

Installation requirements

Installation site

■ Select a site with good air circulation,

so that the cooled air can dissipate and

be replaced by warm air.

■ Avoid direct insolation.

■ When siting the unit in a location

exposed to wind, ensure that the wind

does not affect the fan area. This could

result in an "air short circuit" between

the air being discharged and the air

being drawn in. Strong wind can have

a negative influence on the evaporator

ventilation.

!Please note

An "air short circuit" during

heating operation will result in

the cooled discharged air re-

entering the unit. This can

result in reduced heat pump

efficiency and defrosting prob-

lems.

Avoid "air short circuits".

!Please note

An "air short circuit" during

cooling operation will result in

the heated discharged air re-

entering the unit. This can lead

to high pressure faults.

Avoid "air short circuits".

■ Take the lengths of the refrigerant

lines into account (see "Connecting

refrigerant lines").

■ Select the installation site so that the

evaporator cannot be blocked by

leaves, snow etc.

■ Select the installation site with due

consideration of the physical laws of

sound dissipation and reflection.

Technical guide "Heat pump

principles"

■ Never site in corners, recesses or

between walls.

■ Never install next to or below bedroom

windows.

■ Never install closer than 3 m to path-

ways, downpipes or sealed surfaces.

The cooled air in the discharge area

creates a risk of ice forming when out-

side temperatures fall below 10 °C.

■ The installation site should be easily

accessible, for example for mainte-

nance work (see "Minimum clearan-

ces").
