DANGER: Before starting work, make sure that the pump
has been disconnected from the power supply.
Installation site (Fig. 3)
Provide a weatherproof, frost-free, dust-free and well-venti-

Choose an installation site that is easily accessible.
CAUTION: Dirt can cause the pump to fail. Flush the pipe
system before installation.
NOTE: In the case of the COSMO CPZ A version, the stop

In the case of the COSMO CPZ version, these valves have
to be installed additionally.

installed without being exposed to mechanical stresses.
