Installation and electrical connection
WARNING
Risk of electric shock
Hazards from electric current must be prevented.
Unpack the pump and recycle or dispose of the packaging in an environmentally re-
sponsible manner.
The pump must be installed in a dry, well-ventilated location free of frost on a flat, rigid
surface using the appropriate screws.
CAUTION
Risk of damaging the pump
The presence of foreign matter or impurities in the pump housing may affect the
functioning of the product.
It is recommended to perform any welding and soldering work before installing the
pump.
Rinse the circuit completely before installing and commissioning the pump.
ƒ
The pump must be installed in a place easy to access for the purposes of inspection
or replacement.
ƒ
Install the pump on a smooth floor.
ƒ
The pump must be fixed in place using the 2 holes on the bearing bracket (Ø M8
screw) (Fig. 2).
ƒ
Ensure there is a minimum distance between the motor fan and any surfaces (Fig. 4).
ƒ
For heavy pumps, install a lifting hook (Fig. 3a , pos. 11) in line with the pump axis to
facilitate its disassembly.
ƒ
Remove the condensate plugs (Fig. 1, pos. 12) when the pump is in a condensing en-
vironment. In this case, the motor protection class IP55 will no longer be guaranteed.
WARNING
Risk of accident due to hot surfaces!
The pump must be installed in such a way that no one can touch the hot surfaces of
the product when it is in operation.
WARNING
Risk of tipping
Ensure that the pump is secured to a flat, rigid surface.
CAUTION
Risk of foreign matter in the pump
Ensure that all blanking plugs are removed from the pump housing before installa-
tion.
NOTICE
Each pump may have been factory-tested to verify its hydraulic performance, and
water may be present in the product. For hygiene purposes, the pump should be
rinsed before use.
Install insulating material (cork or reinforced rubber) under the pump to avoid noise
pollution and vibrations being transmitted to the installation.
ƒ
The weight of the piping should not be borne by the pump (Fig. 5).
ƒ
Permitted pump installation positions (Fig. 8).
ƒ
We recommend installing gate valves on the suction and pressure sides of the pump.
ƒ
Use expansion joints to mitigate noise and vibration from the pump if required.
