MALFUNCTION
2. The motor is running, but the
pump is not discharging any
liquid.
3. The pump stops after a short
time of operation because the
thermal motor protection
feature has triggered.
4. The pump cuts in and out too
frequently.
5. The pump does not reach the
desired pressure.
6. The pump does not cut out.
12. Warranty
The present device was manufactured and inspected according to the latest methods. The seller warrants for
faultless material and workmanship in accordance with the legal regulations of the country in which the device
was purchased. The warranty period begins with the day of the purchase and is subject to the provisions below:
Within the period of warranty, all defects which are to be attributable to defective materials or manufacturing will
be eliminated free of charge. Any complaints are to be reported immediately upon their detection.
The warranty claim becomes void in the case of interventions undertaken by the purchaser or by third parties.
Damage resulting from improper handling or operation, incorrect setting-up or storage, inappropriate connection
or installation or Acts of God or other external influences are excluded from warranty.
Parts being subject to wear and tear, such as the pump wheel (impeller), mechanical shaft seals, membranes and
pressure switch are excluded from warranty.
POSSIBLE CAUSE
1. The pump housing is not filled with liquid.
2. Air penetrates into the intake line.
3. Suction height and/or discharge height too
great.
1. The electrical supply does not correspond
to the information given on the type plate.
2. Pump or intake line is blocked by solids.
3. Liquid is too viscous.
4. Temperature of liquid or environment is
too high.
5. Pump is running dry.
1. The membrane of the pressure tank is
damaged.
2. Insufficient pressure in the pressure tank.
3. Air penetrates into the intake line.
4. Check valve (non-return valve) is jammed
or not tight.
1. Cut-out pressure set too low.
2. Air penetrates into the intake line.
1. Cut out pressure set too high.
2. Air penetrates into the intake line.

ELIMINATION
1. Fill the pump housing with liquid (please
refer to "Putting into operation" section).
2. Check to make sure that:
a.) The connection points of the intake
line are tight;
b.) The inlet opening of the intake line
including the check valve (non-return
valve) are immersed into the liquids
being discharged;
c.) the check valve (non-return valve) with
the filter is tight and not jammed;
d.) No siphons (i.e. permanently liquid-
filled loops), kinks, counter-slopes or
narrow spots are present along the
intake lines.
3. Change the arrangement of the installation
so that the suction height and/or discharge
height will not exceed the max. value.
1. Please use a device complying with GS
(German technical supervisory authority)
to check the voltage of the lines of the
connection cord (safety information to be
observed!).
2. Remove possible congestion.
3. Pump may not be suitable for this liquid. If
feasible, the liquid should be thinned.
4. Make sure that the temperature of the
liquid being pumped and the environment
do not exceed the max. admissible values.
5. Eliminate causes of dry-running.
1. Have the membrane or the entire pressure
tank replaced by qualified staff.
2. Use the tank valve to increase the
pressure until it reaches a value of 1.5 bar.
Before that, please open a consumer in
the pressure line (e.g. a faucet) to
depressurise the system.
3. Refer to section 2.2.
4. Eliminate the cause of blocking the check
valve (non-return valve) or replace it if
damaged.
1. Please contact the customer service
department.
