5.4 INITIAL START-UP PROCEDURE

The following procedure should be used to make
the initial start-up of the compressor.
Before initial start up check that fluid is at prop-
er level in the sight glass.
Grease motor per manufacturer's recommenda-
tions.
1. Read the preceding pages of this manual thor-
oughly.
2. Jog motor to check for correct rotation of main
motor and fan (refer to
3. Be sure that all preparations and checks
described in the Installation Section have been
made.
4. Start the compressor (manual mode
AUTO mode )
5. Open the shut-off valve to the service line.
6. Check for possible leaks in piping.
7. Slowly close the shut-off valve to assure proper

Bypasses fluid flow around the cooler until the fluid reaches a
temperature of 180ºF (82ºC). Useful for fast warm-up during
start. Maintains a minimum temperature of 180ºF (82ºC) during
periods of low load or low ambient temperatures.
NOTE: Standard thermal valve temperature is 175ºF/79ºC (oper-
ating temperature of 180ºF/ 82ºC). Thermal valve temperature is
190ºF/88ºC (operating temperature of 195ºF/ 91ºC) for HH, XH
and 24KT machines.
Indicates level of lubricant in the sump. Located on the sump
side, it should show half-full (compressor stopped) for proper
fluid level.
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 indi-
cates the need to clean the strainers fitted to the sight glasses.
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.

nameplate pressure unload setting is correct.
The compressor will unload at nameplate pres-
sure. If adjustments are necessary, see Control
System Adjustments.
8. Observe the operating temperature. Refer to
Section 2.4 for proper operating temperature
range. If temperature exceeds this range, the
cooling system and installation environment
should be checked.
9. Open shut-off valve to the service line.
10. Reinspect the compressor for temperature and
leaks the following day.

On subsequent start-ups, check that the proper
level is visible in the fluid sight glass and simply
