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. See information on page 29 onwards.
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. See information on
page 37 onwards.
Transport and siting requirements
■
The Vitocal 300-G Pro SPS is delivered as a stand-
ard unit. Side panels are packed separately for fitting
on site.
■
The programming unit of the Vitotronic SPS is deliv-
ered loose inside the wiring chamber and must be fit-
ted and connected on site. See page 40.
Unloading and handling
Note
Before unloading, have the recipient check the con-
signment for damage. Note down any damage on the
delivery note and notify the haulage contractor.
■
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, do not tilt the
■
compressor too far: max. tilting angle of the
heat pump 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.
