GUARANTEE AND CLAIMING

Reliable operation and service life of the dispenser depends on correct attendance and maintenance.
Therefore it is necessary that every employee maintaining or attending the dispenser is acquainted with
all principles of correct attendance and maintenance and related regulations for combustibles handling.

Smoking, handling open fire, tanking vehicles with engine running, etc. are particularly forbidden!

Defects and shortcomings owing to incorrect or careless attendance and maintenance of the dispenser and
its individual functional parts are not included in the guarantee. Therefore any complaint within this
matter would be acknowledged.
The disposal of sludge, water or other impurities from tanks (fuel storage tanks) shall be ensured entirely.
It is carried out by means of decantation equipment which shall be a part of the filling station equipment.
If the manufacturer carrying out guarantee repairs identifies excessive quantity of impurities in the
hydraulic system, the complaint will not be accepted and expenses will be charged to the user.

Claims will not be acknowledged due to the following reasons:

–

Use of unsuitable fluid (non-standard liquid fuels, substances containing water, diluting agents, etc.).

–

Shortcomings owing to incorrect design or imperfect assembly of "the lower process equipment",
i.e. tank location, length and diameter of piping, type and characteristics of fittings, overrun of
suction head values etc. – fuel dispenser installation on the filling station must answer the given
criteria from point no 15. hereof instructions.

–

The recommended highest operation suction head is -45 kPa and max. length of suction piping for
individual fluids:
for petrol

35 m

for Diesel oil

40 m

–

Leakage in the hydraulic system of the storage results in permanent air intake into the pumping
monoblock - air separator is in permanent function - dispensing discontinuance occurs.

–

Consequence: increased wear of pumps

–

Faulty check valves in the suction line can cause its systematic discharging ("level drop")

Consequence:

irregular and unreliable run, considerable stressing of pumps, increased wear of

the pump vanes in "idle running", reduction of pump service life.

–

Defects owing to impurities in fluid can result in the seizing of the rotor, destruction of vanes or their
excessive wear as well as excessive wear of rotor, stator and bearings of the gland, etc. With meters
the impurities can result in function locking, excessive wear of slide valve gear, cylinders and packing.

–

Defects owing to faulty high-power wiring at the filling station, e.g.:

incorrect installation of the switchboard

incorrect earthing system

incorrect cable distribution systems - power cables together with communication cables

–

Defects from faulty low power wiring at the filling station, faulty wiring of communication cables
especially as far as interference is concerned

missing UPS (ON LINE) - mains supply

standardised voltage values: U nominal ±15 % with frequency 50 Hz

The guarantee does not cover consumable supplies: filter bushings, V-belts, etc.
The guarantee and claiming are specified in the contract.

The guarantee claims can only be asserted at the purchaser of the fuel dispenser.
Claiming faulty function of the dispenser specify the following data:

–

Serial number of the dispenser, its name, as specified on the rating plate of the dispenser.

–

Precise description of the defect or failure.

–

Description of circumstances when the defect occurred.

–

If a complaint is claimed within the guarantee period, the seals may not be broken without previous
consent.

If  the  seals  have  been  broken  or  some  not  permitted  unqualified  handling  the  dispenser  found  out,  the
complaint will not be admitted.
For dispensers with control system or with control system and local preselection the complaint concerning
the  control  system,  electronics  and  software  of  dispensers  cannot  be  acknowledged  because  of  non-
observance of wiring conditions and operation of the permanent feeding source UPS (UPS - Uninterruptible
Power Supply).
