facing the black fan shroud and counterclockwise if facing the compressor flywheel.)

c.Set both selector switches to the auto position. Compressors will both run until the lead pressure switch closes.

d.Open valve at the air receiver leading to Medical Air System.

e. Check for air leaks at the connections.

9.Check that the compressor operates without excessive vibration, unusual noises or leaks.

10.Check the discharge pressure. Also make sure the air pressure rises to the designated pressure setting by checking the discharge pressure gauge.

11.Check the operation of the pressure switch or the pilot valve for continuous run units by opening the stop valve and confirming the compressor starts or reloads as pressure drops.

1.Inspect and perform maintenance periodically according to maintenance schedule.

2.The maintenance schedule relates to the normal operating conditions. If the circumstances and load condition are adverse, shorten the cycle time and do maintenance accordingly.

3.* The tension of the V-belt should be adjusted during the initial stage and inspected every 1,500 hours afterwards. Proper belt tension for 3/4 to 3 HP units is 12 lbs./.5” deflection; for 5 to 20 HP units, 16 lbs./1.5” deflection
