3. ELECTRICAL CONNECTIONS
WARNING
The installer is responsible for making electrical connections to
the mains supply in compliance with relevant local regulations.
Ensure that a professional electrician carries out the electrical
connections and that the following guidelines are followed:-
• All installations must be provided with an isolator to cut off mains power
supply and coarse current protection in the form of a fuse or MCB rated
at 2-3 times the full load current as given on the pump plate.
• Ensure that the power supply rating complies with the specification on
the pump rating plate.
• Electrical connections must be made according to details in the pump
junction box cover and effective earthing must be provided according to
local regulations.
• Single-phase motors are protected against overloads by a thermal
overload fitted in the motor windings.
4. PRIMING
FILL
WARNING
All non-self priming pumps must be primed
before operation. To do this completely fill
the pump housing with clean water through
the priming plug before switching it on.
When full replace the priming plug and start
the pump checking there is a steady flow at
the pump outlet. The pump should be
primed whenever it has not been used for a
long period of time or when air has entered
into the system.
Serious damage will occur if a pump is not properly primed and
runs without water.
