The electrical installation may only be conducted by a specialist. Local
regulations have to be followed.
Electrical connection work must only be carried out by a qualified electrician
in accordance with the applicable safety rules, see IEC 60204-1.
The motor must be protected by magnetic thermo breaker type GV2 ME14
adjustable from 6 to 10 A from Schneider Electric or similar.
For an operation at 50 Hz the breaker must be set at 8.5 A. For an operation
at 60 Hz the breaker must be set at 10 A.
Therefore, even if the pump is not operating, live voltage is present in the
motor connection box !
Voltage and frequency mentioned on the pump nameplate must agree with
the supply voltage.

Connection to exhaust side
■
No valve or restricting devices should be installed in the exhaust line of the
pump. If an exhaust line is installed, it must at least have the same diameter as
the exhaust flange. It should be installed in a manner so that no condensate can
enter the pump (siphon, slope).
The maximum exhaust pressure must neither exceed 1.15 bar absolute (0.15
bar relative), nor fall under atmosphere pressure minus 15 mbar.
