PRELIMINARY TASKS
6.4
Checking the safety valves
6.4.1
Check that safety valves are working properly by starting the compressor with the end taps closed:
this will raise circuit pressure fast and trip the valves when their pressure setting is reached.
The valves are pre-adjusted to 225 bar (3200 PSI), 300 (4300 PSI) and 330 bar (4700 PSI).
Check that the bottles to be refilled are in good condition: they must have been tested by the relevant
authorities (stamped and/or certified). Run a visual check on the exterior.
Check that the refill hose and relevant fitting are in good condition.
After being refilled do not empty the bottles completely, not even during winter storage or long periods of
inactivity: this will stop humidity getting in.
IMPORTANT
Tampering with the safety valve to increase the pressure setting is strictly forbidden.
Tampering with the safety valve can seriously damage the compressor, cause serious
injury to personnel and renders the warranty null and void.
IMPORTANT
Should the safety valve fail to work properly contact the AEROTECNICA COLTRI
assistance service.
DANGER
Should bottles show evident signs of internal/extern al corrosion, do not refill them
even if they have been tested.
WARNING
Use only tested bottles (as proven by a test stamp and/or certificate).
The working and bottle refill pressures are shown on the bottles themselves.
It is forbidden to refill them at a pressure greater than that indicated.
