Operating procedure. The following steps are to be followed in sequence for proper operation under normal
conditions.
a. Starting
(1) Inspect the electric motor to make sure it is properly wired for incoming power source and that the main power
source is ON.
(2) Close the globe valve (9, figure 2-1) by turning handle clockwise.
(3) If not connected, attach air service hose (16, figure 2-1) to globe valve (9) and attach inflator gauge (10) to
hose (16).
(4) Turn the ON-OFF switch (4, figure 2-1) to "ON" position.
CAUTION
Check rotation of motor pulley. Proper rotation is clockwise when viewed
from control box side. If rotation is not correct, reverse any two power
source lead connections in control box.
NOTE
If motor does not start, press the reset button (3, figure 2-1). If motor
still does not start, refer to table 3-1 and troubleshoot.
b. Operating.
(1) The unit is automatic and will run until air pressure in air receiver tank (21, figure 2-1) reaches 200 psi, +0,
-10 psi (14.1, +0, -0.70 kgs/cm2), then, the motor will stop until tank pressure drops to 175 psi, 10 psi (12.3, * 0,70
kgs/cm2). When the low pressure is reached, the motor will start and run until the cut-out pressure is again reached.
(2) When operating pressure is attained, read air receiver tank pressure on air pressure gauge (5, figure 2-1),
open glove valve (9) by turning handle counterclockwise. Attach inflator gauge (10) to tire or system requiring com-
pressed air.
c. Stopping.
(1) When servicing is complete, close globe valve (9, figure 2-1) by turning handle clockwise. Open inflator
gauge (10) to relieve pressure in service hose (16). Coil hose on hanger provided.
(2) Turn ON-OFF switch (4) to OFF position.
(3) Open drain cock (11) in bottom of air receiver tank (21) to relieve pressure from tank and drain off condensate.
(4) Perform your after operation PMCS.
