For long and trouble-free operation of the pump, following
points should be checked regularly:
- Nominal current (A): Check with amp-meter.
- Pump parts and impeller: Check for possible wear.
Replace defective parts.
- Ball bearings: Check the shaft for noisy or heavy operation
(turn the shaft by hand). Replace defective ball bearings. A
general overhaul of the pump is usally required in case of
defective ball bearings or poor motor function. This work
must be carried out by an authorized
service workshop.
- Cable entry: Make sure that the cable entry is watertight
and that the cables are not bent sharply and/or pinched.
Servicing Contract
For a regular expert execution of all necessary maintenance
and inspection we recommend the conclusion of a servicing
contract by our HOMA Service. Please contact our HOMA
customer service.
Return of pumps
If a pump has been used for a liquid which is injurious to
health or toxic, the pump will be classified as contaminated.
If HOMA is requested to service the pump, HOMA must be
contacted with details about the pumped liquid, etc. before
the pump is returned for service. Otherwise HOMA can re-
fuse to accept the pump for service (see attachment).
Possible costs of returning the pump are paid by the cus-
tomer. However, any application for service (no matter to
whom it may be made) must include details about the
pumped liquid if the pump has been used for liquids which
are injurious to health or toxic.

paired by a quali-
fied electrician
Pump operates at
below-standard
performance.
• Voltage drop
• Leakage in the dis-
charge pipe
• Suction sieve blocked
by impurities
• Pump does not reach
the required head
• Check the voltage
• Check the
discharge
pipe and seal up
• Clean the suction
sieve
• Compare the
pump
performance with
the required head
Pump operates, but
motor starter trips
out after a short
while
• Voltage drop
• Check the voltage
• Impeller is blocked by
impurities
• Clean the impeller
• Temperature of the
pumped medium is
too
high
• Please check the
temperature of
the medium. The
temperature of
the pumped
medium
must be

WEEE Notice
The Directive on Waste Electrical and Electronic Equipment
(WEEE), which entered into force as European law on 13th
February 2003, resulted in a major change in the treatment
of electrical equipment at end-of-life.
The purpose of this Directive is, as a first priority, the preven-
tion of WEEE, and in addition, to promote the reuse, recy-
cling and other forms of recovery of such wastes so as to
reduce disposal.
The WEEE logo on the product or on its box indicates that
this product must not be disposed of or dumped with your
other household waste. You are liable to dispose of all your
electronic or electrical waste equipment by relocating over to
the specified collection point for recycling of such hazardous
waste. Isolated collection and proper recovery of your elec-
tronic and electrical waste equipment at the time of disposal
will allow us to help conserving natural resources. Moreover,
proper recycling of the electronic and electrical waste
equipment will ensure safety of human health and environ-
ment. For more information about electronic and electrical
waste equipment disposal, recovery, and collection points,
please contact your local city centre, household waste dis-
posal service, shop from where you purchased the equip-
ment, or manufacturer of the equipment.
