While dispensing, do not inhale the pumped product

Should you spill any fluid while dispensing, bank it with earth or sand to absorb
it and limit its spreading

MAINTENANCE
Safety instruc-
The dispensing system was designed and built to require a minimal amount of maintenance.
Before carrying out any maintenance work, disconnect the dispensing system from any electri-
tions
cal and hydraulic power source. During maintenance, the use of personal protective equipment
(PPE) is compulsory.
In any case always bear in mind the following basic recommendations for a good functioning
of the pump
Authorised
All maintenance must be performed by qualified personnel. Tampering can lead to performance
degradation, danger to persons and/or property and may result in the warranty being voided.

Measures to
Whenever there is risk of frost, empty the circuit and the pump, taking care to place the pump in
an environment where the temperature is no lower than 0°C/32°F.
be taken
Check that the labels and plates found on the dispensing system do not deteriorate or become
detached over time.

Depending on the system characteristics, the priming phase can last from several sec-
onds to a few minutes. If this phase is prolonged, stop the pump and verify:
- that the pump is not running completely dry (fill with fluid from the delivery line);
- that the suction pipe guarantees against air infiltration;
- that the suction filter is not clogged;
- that the suction height is not higher than 2 mt.
- that all air has been released from the delivery pipe.
When priming has occurred, verify that the pump is operating within the anticipated
range, in particular:
- that under conditions of maximum back pressure, the power absorption of the motor
stays within the values shown on the identification plate;
- that the suction pressure is not greater than 0.5 bar;
- that the delivery back pressure does not exceed the maximum back pressure for the
pump.
The by-pass valve allows functioning with delivery closed only for short
periods (max. 3 minutes)
To avoid damaging the pump, after use, make sure the pump is off.
In case of a power break, switch the pump off straight away.
Should any sealants be used on the suction and delivery circuit of the
pump, make sure that these products are not released inside the pump.
Foreign bodies in the suction and delivery circuit of the pump could cause
malfunctioning and breakage of the pump components.
In case of prolonged dry-running of the pump, the suction circuit may be empty and
suction may become difficult. If so, fill the suction circuit with demineralised water
