NOTICE :
FOLLOW ALL HAZARD WARNINGS AND NOTICES
IN THE § ”SAFETY DATA” AND ”MAINTENANCE”
OF THIS MANUAL.
1.
When re-installing compressor, check for the following :
• Correct compressor rotation with respect to the
drive.
• Correct orientation of compressor with respect to
the piping.
• Correct coupling alignment.
• Noise due to rubbing fans or guards, etc.
2.
Install a pressure gauge to the discharge port of the
compressor.
3.
Run compressor by following steps under the § “USE
- Starting-Up” of this manual.
NOTE :
DO NOT CLOSE THE VENT VALVE YET.
4.
After start-up, verify the following :
• Check compressor speed. Compressor speed must
fall within the operating parameters indicated in the
§ ”TECHNICAL DATA”.
• Re-check to verify correct compressor rotation.
5.
Perform a Pressure Test :
• Isolate the piping from the tank by closing off the
trailer isolation valve.
• Slowly close the vent valve and observe the pres-
sure reading on the gauge installed on the compres-
sor. The pressure must not exceed 40 psi (2,75 bar).
• After recording the gauge reading, open the vent
valve.
4. MAINTENANCE (continued)
The compressor must be scrapped in compliance with the
regulations in force.
During this operation, particular care must be paid to the drai-
