Preparing for installation

General information on electrical connection

Electrical connection of system components
■
(pumps, mixers, valves, message facilities, contac-
tors, function extensions, sensors etc.):
Connections are made inside the heat pump wiring
chamber. Observe information from page 31.
Power supply:
■
The number of power cables from the meter box to
the heat pump wiring chamber depends on the sys-
tem version and tariffs used. Observe information
from page 45.

Transport and siting requirements

The Vitocal 300-G Pro is delivered as a standard
■
unit. Side panels are packed separately for fitting on
site. See pages 23 to 25.
■ The programming unit of the Vitotronic 200 is deliv-
ered loose inside the wiring chamber and must be fit-
ted and connected on site. See page 49.

Unloading and handling

Note
Before unloading, have the recipient check the con-
signment for possible damage. Note down any dam-
age on the delivery note and notify the haulage con-
tractor.
Lifting gear, such as slings and cross beams, must
■
be provided on site.
■ The lifting capacity of each sling and that of the cross
beam must be at least equal to the shipping weight.
See "Specification".
■ Only use suitable equipment for unloading the lorry;
see the following chapter.
!
Please note
To prevent appliance damage, observe the fol-
lowing when unloading and handling the heat
pump.
■ Never put weight on top of the appliance.
To protect the paintwork, wrap the lifting gear
■
(such as ropes, cross beams) and place pad-
ding between the heat pump and lifting gear.
■ Observe correct weight distribution when lift-
ing. Due to the heat exchangers, the heat
pump's centre of gravity is at the back, by the
hydraulic connections.
Avoid impact and shocks to prevent damage
■
to the internal pipework of the heat pump.
■ To protect the refrigerant circuit, avoid strongly
tilting the compressor: tilting angle of the heat
pump max. 30°.

Accessories are delivered separately.
■
No charging with oil or refrigerant required. The heat
■
pump has been charged with oil and refrigerant at
the factory.
Viessmann (Switzerland) AG accepts no liability for
any damage resulting from incorrect handling.
