Before any intervention on a pump, it is imperative to carry out a
general procedure of decompression and purge.
In order to avoid the risk of personal injury, product injections, injuries
caused by moving parts or arcing, it is essential to follow the following
procedure before any intervention during system shutdown, assembly,
cleaning or changing the nozzle.
Lock the guns (valve, tap, etc.) to OFF.
Shut off the air supply via the pressure relief valve to
remove residual air from the engine.
Unlock the gun (valve, tap ...).
Bring the gun (valve, tap ...) to a metal bucket to
collect the product. Hold it against the wall of this
bucket to avoid interrupting the continuity of the
earthing (use the wire with stirrup to put the metal
bucket to earth).
Open the gun (valve, tap) to bleed the circuit.
Lock the gun (valve, tap) to OFF.
Open the pump bleed valve and collect the product
in a well-grounded metal bucket.
Leave this purge valve open during the whole period of
the operation.
Check the conformity of the wiring before intervention.
When the compressed air is exhausted, the sudden drop in pressure
causes the air temperature to drop below 0°c / 32°F. Any liquid or water
vapour then turns to ice.
Higher air pressures pack high amounts of air and water vapor in each
cycle and create more expansion and ice. Higher cycle rates also build
up the ice and lower the motor temperature faster.
Warm humid climates can produce high levels of icing because of the
higher humidity levels. Low ambient temperatures near 0°c / 32°F make
it easier for the motor parts to drop below freezing.
