WARNING
CLEANING
If the pump has been running in very dirty water, let it
run for a while in clean water, or flush it through the
discharge connection. If clay, cement or other similar
dirt is left in the pump it may clog the impeller and seal,
preventing the pump from working.
During a long period of storage, the pump must be test
run every other month to prevent the mechanical seals
from sticking together.
Watch out for the starting jerk, which can
be powerful.
Always lift the pump by its carrying handle
or lifting eyes, never by the motor cable or
the hose.
Care and Maintenance
INSPECTION
Regular inspection and preventive maintenance ensure
more reliable operation.
The pump should be inspected at least twice a year, more
frequently under severe operating conditions.
TIGHTENING SCREWS
During assembly or service of the pump we recommend
that the screws be tightened to approximately
4.5 - 6 ft lbs (6-8Nm).
This tightening torque ensures that the parts are correctly
fastened and that the pump will operate as intended.
NOTICE: Make sure that the oil-plug screw is not
overtightened.
Be sure to disconnect the power supply
before attempting inpection, as the pump
may start automatically.
LUBRICATING SCREWS
To maintain screw tightness use a little mineral oil on all
non-stainless screws (non-synthetic lubricants!).
NOTICE: When using stainless steel screws on stainless
steel parts we recommend that ARAL DEGOL
GS 460 or National Chemseal THREAD-EZE
lubricants be used to prevent screws from
seizing or getting stuck.
If the motor cable on this pump is damaged
the cable may only be changed by a repair
shop authorized by the manufacturer. This is necessary as
special tools are required to change the cable.
