Installation and electrical connection
The baseplate can be poured out after fixing. The process of pouring out reduces vibra-
tions to a minimum.
ƒ
Wet the base surface before pouring out the concrete.
ƒ
Use a suitable, non-shrink mortar for pouring out.
ƒ
Pour the mortar through the openings in the baseplate. Be sure to avoid hollow
spaces.
ƒ
Plank the base and baseplate.
ƒ
After curing, check the anchor bolts for a tight fit.
ƒ
Coat the unprotected surfaces of the base to protect from moisture.
The pipe connections of the pump are fitted with dust caps so that no foreign objects
can penetrate during transport and installation.
ƒ
These caps must be removed before connecting the pipes.
CAUTION
Incorrectly carried out pipework/installation can lead to material dam-
age! Welding beads, cinder and other contaminants can damage the
pump!
• The pipes must be sufficiently dimensioned, taking the pump inlet pressure into
account.
• Connect the pump and pipes using suitable gaskets. Take the pressure, temper-
ature and fluid into account. Check the gaskets for proper fitting.
• The pipes must not transfer any forces to the pump. Brace the pipes directly before
the pump and connect them without tension.
• Observe the permissible forces and torques on the pump connecting pieces!
• The expansion of the pipes in the event of a temperature rise is to be compensated
by suitable means.
• Avoid air pockets in piping by means of appropriate installations.
NOTICE
Make subsequent work on the unit lighter!
• To ensure the entire unit does not have to be emptied, install a non-return valve
and shut-off valves before and after the pump.
