nitrogen mixture for leak testing. 
 
              Attach a refrigerant test gas cylinder to 
your service manifold and connect the mani-
fold to the charging port on the liquid line 
valve.  Charge an R-22/Nitrogen mixture into 
the system, raising the pressure to the remote 
unit’s nameplate for the low side and high side 
pressures.  Using an electronic detector, care-
fully check the entire system for leaks.  Take 
special care to inspect all brazed and flare con-
nections. 
 
EVACUATION –  
 
              After the system is  proven leak tight, 
thoroughly evacuate the system according to 
the follow procedure: 
 
1. Discharge the refrigerant-nitrogen mixture, 

allowing it to blow from the system as rap-
idly as possible, into an empty cylinder.  Be 
sure that all service valves and solenoid 
valves are open to allow all of the mixture 
to be discharged. 

 
2. Connect a deep-drain vacuum pump to 

both the high and low side of the system. 
Pull a vacuum on the system to at least 
1500 microns. 

 
3. Break the vacuum by adding refrigerant 

into the system until the pressure is above 0 
PSIG.  Always charge the refrigerant line 
into the system through a new drier in the 
charging manifold line.  A 16 cubic inch 
drier is sufficient for this purpose. 

4. Repeat steps 2 and 3 two more times, the 

third time evacuating the system to 500 mi-
crons. 

 
OPERATIONAL DATA –  
 
             The following is  typical data for GIM-6 
based on lab tests, and may vary under field 
operating conditions. 
 

 
                                      R502              R404A                             
AMBIENT TEMP        75ºf                  75ºf 
HEAD PRESSURE       225 PSI           235 PSI 
SUCTION PRESS            3.5 PSI              7-8 PSI 
DISCHARGE AIR         -25ºF                -25ºF 
RETURN AIR               -10ºF                 -10ºF 

 
 
COMPRESSOR –  
 
             The compressor is mounted on springs 
and banded for shipping purposes and this 
band needs to be cut upon installation.  Do not 
loosen the compress or mounting bolts as these 
are factory pre-set for proper riding on the 
springs. 
 
CONDENSER FAN MOTORS –  
 
             There are two condenser fan motors on 
the GIM-6, one cycles  with the compressor 
during its off cycle while the other runs con-
tinuously.  This is to allow the compressor and 
condenser to cool even further during the off 
cycle, thus reducing the head pressure while 
the cabinet is running and reducing the am-
perage  draw of the compressor.
