Maintains 50 psig (3.5 bar) in the receiver tank when the
compressor is running loaded. Also incorporates a check
valve, which prevents compressed air backflow from the sys-
tem when unloaded or shutdown.
Vents the sump vessel to atmosphere before the com-
pressed air pressure exceeds rated tank pressure. Its oper-
ation indicates fault with the Supervisor operation unload
pressure set too high or failure of solenoid valve #1.
Vents the sump vessel to atmosphere during unloading and
shutdown.
Bypasses fluid flow around the cooler until the fluid reaches
a temperature of 170°F, 77°C (195°F for water cooled KT and
≥
150 psi/ 10.3 bar). Useful for fast warm-up during start.
Maintains a minimum temperature during periods of low load
or low ambient temperatures.
Blocks the flow of fluid to the compressor during shutdown,
thus preventing the discharge of fluid through the compres-
sor inlet pipework.
Indicates level of lubricant in the sump. Located on the sump
side, fluid level should be maintained at a level between the
high and low sight glass.
Indicate fluid flow in the separator return lines. Large flow
should be visible during full load operation; little to no flow
during unloaded operation. Sluggish flow during full load
operation indicates the need to clean the strainers fitted to
the return lines.
De-energizes the starter, via the Supervisor, if the
water pressure falls below 10 psig (0.7 bar). This switch is not
adjustable. Used on water-cooled packages only.
Lubricant sump drain valve.
6.3 INITIAL START-UP PROCEDURE
The following procedure should be used to make
the initial start-up of the compressor.
1. Read the preceding pages of this manual thor-
oughly.
2. Jog motor to check for correct rotation of main
motor and fan motor (refer to Section
3. Be sure that all preparations and checks
described in the Installation Section have been
made.
4. Open the shut-off valve to the service line.
5. Check for possible leaks in piping.
6. Slowly close the shut-off valve to assure proper
nameplate pressure unload setting is correct.
The compressor will unload at nameplate pres-
sure. If adjustments are necessary, see Control
System Adjustments.
7. Observe the operating temperature. If the oper-
ating temperature exceeds 200°F (93°C) [215°F
(102°C) for water-cooled 24KT and > 150 psi],
