CHAPTER 2: OPERATION
2.1
Preparation for Operation
Prior to operating the unit for the first time, read this Instruction Manual carefully.
1. Make sure that all persons operating the compressor unit and associated equipment are familiar with
the function of all controls and indicators.
2. Thoroughly comply with the paragraphs titled Safety contained in the Appendix to this manual.
3. If the unit has been out of service for two years or more and uses synthetic compressor oil change
the compressor oil. If the unit uses petroleum based compressor oil change it after being out of ser-
vice one year.
4. During the initial operation or prior to operation subsequent to repairs operate the unit for at least
five minutes with open outlet valve (unpressurized) to ensure proper lubrication of all parts before
pressure is built up.
5. Prior to each operation check the oil level according to Section 2 Lubrication and determine
whether maintenance is necessary in accordance with Section 13.
6. Every time the unit is started, check all systems for proper operation. If any malfunction is observed
stop the unit immediately and find the cause of the fault or call the service department.
2.2
Starting the Unit.
1. Close condensate drain valves and run the unit to the final pressure. Check final pressure safety
valve and pressure gauge.
2. As soon as the final pressure safety valve blows off, open the condensate valve and drain conden-
sate. The unit is now ready for filling operations.
2.3
Filling Procedure
^ WARNING ^
Ensure the intake air is free from noxious gas, exhaust fumes and solvent vapors.
^ WARNING ^
Never open fill valves or shut off valves when under pressure and the hose is not connected as discharging
high pressure compressed air can cause serious accidents.
^ WARNING ^
Fill hoses must be in satisfactory condition and the threads must be undamaged. Pay particular attention to
the interface from hose fitting to hose. If the rubber is scored, the hose must be discarded, otherwise water
can corrode the wire gauze causing a hose failure.
