7. Make sure the inlet filter is properly installed. 8. Confirm that the drain valve is closed. 9. Visually check the rotation of the compressor pump. If the rotation is incorrect, have a qualified electrician correct the motor wiring. START-UP AND OPERATION 1. Follow all the procedures under “Before start-up” before attempting operation of the compressor. 2. Switch the electric source breaker on. 3. Both dryers should be plugged in and set at the on position. 4. Dewpoint & CO Monitors should be on and the sampling valves open. Calibrate Dewpoint and CO per enclosed manufacturer’s instructions. 5. Ensure water lines are properly installed to water-cooled aftercoolers. Turn on water. IMPORTANT: This is not a standard option. Check to see if water- cooled aftercoolers were provided. 6. Compressor unit isolation valves are preset at the factory in the open position except for tank by-pass which must remain closed during normal operation. 7. Dryer and filter isolation valves: Valves should be open to one dryer and one filter bank. 8. Close valve leading to the Medical Air System from receiver on the compressor unit. a. Turn both fusible/breaker disconnects to the on position. Low pressure alarm will sound. Silence the alarm by pushing alarm acknowledge button. b. Jog each compressor in the manual position on the selector switch to check for rotation.

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 Inspect Replace + + 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...
