OPERATION

First use

To make optimum use of the pneumatic pump, we strongly recommend
that you follow the procedure set out below. This reduces risks for the
operator. After installation of the product, the starting state must involve
closure of all the ball valves in the air line, and closure of the dispensing
device and the pressure regulator with pressure gauge.
Opening the
Keeping the pressure regulator in the closed position, open the air line

ball valves in sequence. Then keep the dispensing valve open over a
suitable metal container to receive the fluid from it once the system is
primed. Take extreme care and keep the dispensing nozzle in contact
with the wall of the container. We also recommend that you wear
personal protective equipment.
Opening the
Slowly open the pressure regulator with pressure gauge, as gradually as
pressure and
possible. Monitor the pressure by means of the pressure gauge indicator
priming
and wait until you hear the pneumatic pump come into operation to allow
priming. As soon as all the air in the fluid line has been expelled and the
dispensing valve has started dispensing, close the dispensing valve.

Normal use

We recommend that you adjust the pressure to the minimum quantity of
air necessary to obtain the desired dispensing results. Take the utmost care
when adjusting the pressure.

NOTE
After initial priming, if the air line is open, opening the dispensing valve will
immediately start the pneumatic pump. Closing the dispensing valve will stop
the pneumatic pump.
WARNING
The system supplies fluids at high pressure, such a pressure as to be a
source of danger for the operator. Supply with caution the first time, and in
conditions of maximum safety, in order to acquire a correct perception of
the operation of the system.
Interrupt supply immediately if there are sparks or electrical discharge.
