a screw locking liquid or a centre punch mark. Afterwards when the pipe support clamp has been
removed, the pump can be lowered to plate 380 and after inserting the O-ring supplied (to seal
against smell) screwed to the foundation frame.
To seal against smell place the sealing discs supplied underneath the plate screw fitting (screw
head or hexagon nut).
4.3 Connecting the Pipes to the Pump
• When laying the pipes make sure that the pump is accessible for maintenance and assembly.
• Connect pressure line with the nominal width 100 above the plate in such a way that the pump
will not be subject to stress during operation due to pipe torque.
• If pipes are to be connected with an elastic tension clamp the pipes must have an external
diameter of 108 mm.
• Before connecting to the pump: Remove protective coverings from the pump supports.
• Before starting operations remove coarse impurities from the pump shaft.
• When emptying the pipes and pump shaft make sure that the pump is suitably conserved
(otherwise it can rust which will cause problems when operations are started).
4.4 Electrical connection
The electrical connection work may only be carried out by an authorised
professional. The rules and regulations valid for electrical technology, especially
those concerned with safety measures, must be observed. The regulations of the
national power supply companies operating in that area must also be observed.
Details about electrical connections you can see in the operating instruction of the motor.
4.5 Starting up
The plant may only be started up by people who are familiar with the local safety
regulations and with these Operating Instructions (especially with the safety
regulations and safety instructions given here).
Lubricating the Slide Bearings
• Pure water or grease for lubricating slide bearings must be supplied to the slide bearings before
the pump is taken into operation for the first time, see Point 2.3 „Storage and Lubrication“.
• If the lubricant supply is switched on and off automatically with the pump, lubricant must be
applied to the slide bearings a few seconds before the pump is started.
• Only switch off the pure water or grease supply after the pump has been turned off.
• If there is danger of frost insulate the lubricant pipes or protect with an additional frost
protection heating system.
