safety precautions could also invalidate any claims
for damages.
In particular, lack of care may lead to problems
such as:
• Failure of important pump or machinery functions,
22
• Personal injury due to electrical, mechanical and
bacteriological causes,
• Damage to property.
2.4 Safety precautions for the operator
Existing regulations for the prevention of acci-
dents must be followed.
Dangers caused by electrical energy are to be
excluded. Directives issued by the VDE [German
Association of Electrical Engineers] and the local
electricity supply companies are to be observed
2.5 Safety information for inspection and assembly
The operator must ensure that all inspection and
installation work is carried out by authorised and
qualified specialists who have carefully studied
these instructions.
Work on the pump/machinery should only be car-
ried out when the machine has been brought to a
standstill.
2.6 Unauthorized modification and manufacture of
spare parts
Alterations to the pump or installation may only
be carried out with the manufacturer's consent.
The use of original spare parts and accessories
authorised by the manufacturer will ensure safety.
The use of any other parts may invalidate claims
invoking the liability of the manufacturer for any
consequences.
2.7 Unauthorised operating methods

ATTENTION!
against moisture and mechanical dam-
age caused jolts/impacts. It should not
be exposed to temperatures outside the
range -10 °C to +50°C.
4 Scope of application
The CC-Switchgear is used to automatically con-
trol of pressure boosting systems (Single- and
multipump units).
It is used in watersupplies of residential high rise
buildings, hotels, hospitals, administrative and
industrial buildings.
In conjunction with suitable sensors the pumps
run on a low noise and energy savinjg level. The
power of the pumps is adapted to the constantly
changing requirements of the pressure boosting
system.
