T.I.P. HWW 6000 INOX NIM TLS Mode D'emploi page 18

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.
All parts were manufactured using maximum care and high-quality materials and are designed for a long lifecycle.
It should be understood, however, that the wear and tear depends on the kind of use, the intensity of use and the
internals of maintenance. Complying with the installation and maintenance information contained in the present
operating instructions will therefore considerably contribute to a long lifecycle of these wearing parts.
In case of complaints, we reserve the option of repairing or replacing the defective parts or replace the entire
device. Replaced parts will pass into our property.
Claims for liquidated damages are excluded unless they are caused by wilful acts or negligence on the side of the
manufacturer.
The warranty does not provide for any claims beyond those referred to above. The warranty claim has to be
evidenced by the purchaser in the form of the submission of the sales receipt. The present warranty commitment
is valid in the country in which the device was purchased.
Please note:

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 are 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.
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.
2. Refer to section 2.2.
1. Please contact the customer service
department.
2. Refer to section 2.2.
