START UP / SHUT DOWN

Start Up
First of all, read and check all safety, assembly and electrical instructions in manual.
Make sure that the pump and suction pipes are completely filled with water. There is no problem for the pumps which have
positive suction head. If there is a valve on suction line, it must be opened and air taps are loosened to enable the water re-
places air in the pump, until it is completely full with water.
Check if the shut off valve in the suction line is open and the shut off valve in discharge line is closed. Never run it dry.
Switch on the circuit breaker and run the motor.
Wait 3 sec. until the motor reaches the full speed for 7,5 – 10 HP pumps (on star-delta running motors wait until it switches on
delta)
Open the discharge valve slowly for water hammer.
Never run the pump for along period against a closed discharge valve. (At zero flow)
Stand-by pumps should be run for a short time at least once a week to ensure they are in constant readiness for operation.
Adjust the flow regulating valve at the pump discharge side but never throttle the valve at suction side.
Suction valve should always remain fully open while pump is running and must not be used to regulate the flow. It is only for
maintenance and repair of the pump.
The pump should be shut down immediatly and the problem should be corrected if the pump is running at its rated speed and
found any of following faults :
• Pump doesn't delivery any water.
• Pump doesn't deliver enough water.
• Flow is going down.
• Motor overheating.
• Vibration on pump, high noise level.
If faults occur which are not listed here, or which cannot be traced back to the listed causes, we recommend consulting the
factory.
Shut Down
Slowly close the shut-off valve in the discharge line for water hammer.
Switch off the driver. Ensure the pump set runs down smoothly and quietly to a standstill.
If the set is to remain out of services for a long time, close the shut-off valve in the suction pipe. Close off the auxiliary connec-
tions. In the event of frost and/or prolonged standstill, drain the pump or otherwise protect it against freezing.
MAINTENANCE
This pump does not need a special maintenance!
The bearings of the motor are always life-time grease lubricated and maintenance-free.
You must clean the filter periodically. If you will not use the pump for a long time, pull out the gasket, clean up and set it. Gas-
kets can only be cleaned with silicone based greases. (Do not use petroleum based- or vegetable oils)
