The following values must be met:
During commissioning, the insulation resistance of 20 MΩ
must be met or exceeded. For additional measurements,
the value must be larger than 2 MΩ. Insulation resistance
is too low: Moisture may have penetrated into the cable
and/or the motor.
Do not connect machine; consult the manufacturer!
Visual inspection of the power supply leads
The power inlet leads must be inspected for bubbles,
cracks, scratches, scour marks and/or crushing zones.
If damages are detected, the damaged power inlet lead
must be replaced immediately.
The leads may only be replaced by the manufactur-
er or an authorised/certified service workshop. The
machinery must only be started after appropriate
repair of the damage!
Visual inspection of the cable holders (biners) and the
wiring (traction cable)
If the machine is used in basins/shafts the hoisting wires/
cable holders (biners) and the wiring are subject to con-
stant wear and tear. Regular inspections are required to
prevent a complete wear and tear of the hoisting wires/
cable holders (biners) and/or wiring and a complete dam-
age to the power cable.
The hoisting wires/cable holders (biners) and the wir-
ing must be replaced immediately if there are slight
signs of tear and wear!
Visual inspection of accessories
The accessories, such as for example suspension devic-
es, lifting devices, etc. must be checked for correct fitting.
Loose or defective accessories must be repaired/replaced
immediately.
Visual check for pumps with oil barrier chamber
OIl level and oil condition:
The condition of the axial face seals can be checked by
visually inspecting the oil. To do so, proceed as follows:
•
Position pump vertically and unscrew the Allen
screws (Pos.914.01).
•
Lift the motor off of the pump casing.
•
Unscrew the hexagon nut (Pos.70) and the impeller
(Pos.230) with the washer (Pos.522) and the circlip
(Pos.930.02) from the motor shaft.
•
Position the motor with the shaft end facing up and
loosen the connecting screw (Pos.903).
•
Remove a small amount of oil. If the oil is milky or
cloudy, this indicates a defective shaft seal. In this
case, have the condition of the shaft seals checked
by a HOMA specialist workshop or the factory
Customer Service department.

Oil type: biodegradable HOMA-ATOX. Used oil must be
disposed of in accordance with the valid environmental
regulations.
Overhaul
During an overhaul, in addition to normal maintenance
work, the motor bearings, shaft seals, O-rings and the
power supply lines are also checked and replaced if
necessary. This work may only be performed by the man-
ufacturer or an authorised/certified service workshop.
Changing operating fluid
The drained operating fluid must be checked for con-
tamination and water additions. If the operating fluid is
seriously contaminated and more than 1/3 of the fluid is
water, the fluid exchange must be repeated again after
4 weeks. If water is still present in the operating fluid, a
seal may be defective. Please consult your manufacturer.
When using sealing chamber or leakage monitoring, in the
event of a defective seal, the display will light up again
within the next 4 weeks after the exchange.
Generally, the following applies when changing op-
erating fluid: Turn off machine, allow it to cool, dis-
connect from the power supply (to be carried out by
a specialist!), clean and place on a solid surface in a
vertical position. Warm or hot operating fluid may be
under pressure. The emergent operating fluid may
cause burns. Therefore, allow the machine to cool to
ambient temperature first! Secure against tipping over
and/or sliding!
