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 sepa-

rator 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 situa-

tions 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 

separator 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.
