General

Anchor the pump properly.
Installation, operation and maintenance has to be done by qualified and well
prepared personnel.
The pump must be provided with lockable circuit breaker to avoid
inadvertant starting.
Before any service or maintenance in the pump or system, shut off the power
and lock the starting device to prevent inadvertent start. Close the valves on
the in- and outlet line and drain the pump and system before it is separated
from the system. Follow the instructions for disassembly/assembly (see
paragraph 3.5 "Disassembly and assembly").

Installation and piping

• Use at least the same diameter on pipes from and to the pump as for the diameter of
the in- and outlet ports.
• Flush all pipes before installing the pump.
• Install the pump closest possible to the tank to be pumped from.
• Bolt the pump in place horizontally.
• Only use plastic pipe connections.
• Use care to prevent scraps or trashes from entering the piping during piping work.
• Only use pipe sealants formulated specifically for plastics, i.e. Teflon tape, Permatex
no. 2, etc.
