EQUIPMENT START-UP CHECK SHEET

UNIT CHECKS (NO POWER)

The following basic checks should be made with the
customer power to the unit switched off.
Proper electrical lock out and tag pro-
cedures must be followed.
Check the system 24 hours prior to initial start:
1. Inspect the unit for shipping or installation
damage.
2. Ensure that all piping has been completed.
3. Assure the unit is properly charged and there are no
piping leaks.
4. Open each system suction service valve, discharge
service valve, economizer service valve, liquid line
stop valve, and oil line ball valve.
5. The oil separator oil level(s) should be maintained
so that an oil level is visible in either of the oil
separator sight glasses when a compressor is running
at high speeds for 10 to 15 minutes. An oil level
may not be visible in the sight glasses when the
compressor is off and it may be necessary to run the
compressor to obtain a level. In shutdown situations
and at some load points, much of the oil may be in
the condenser and the level in the separators may
fall below the bottom sight glass.
On systems with dual oil separators per compressor,
one separator may show a lower level or no level,
while the other separator shows a level between the
2 sight glasses. This is normal and a level is only
required in one separator. Do not add oil to raise
the level in the other oil separator.
Oil levels in single separator systems should not go
above the top of the upper sight glass. Dual separa-
tor systems should also not show oil levels above the
top of one of the sight glasses. In the rare situation
where oil levels are high, drain enough oil to lower
the level to the bottom of the top sight glass.
