OMB/C & OLC adapter kits
Kit ACA (pipe thread), ACB (UNF thread) and CO2
(UNEF thread) for Scroll Compressors
1. Assure that there is no pressure in the compressor
crankcase and unscrew the original sight glass to the
compressor. Take note of the original oil level since oil may
be lost when the sight glass is removed. Tip the compressor
to avoid oil loss if possible.
2. Using PTFE tape as a sealant, thread the adapter into the
compressor with the three hole flange ring installed on the
adapter. For Transcritical CO2, use 5 hole flange with CO2T
Adapter. Torque the adapter to 30-40 ft.-lbs. (ACA and ACB)
and torque the adapter to 37-44 ft.-lbs. (CO2). Take care not
to scratch the O-ring seal surface of the adapter.
3. Using the O-ring and bolts provided, install the OMB control
unit to the adapter flange. (Note: The three holes are not
equidistant, so make sure they are the proper orientation
with the OMB mounting holes.) The top of the control unit
must be horizontal with the oil inlet fitting to the left. Torque
the bolts to 120 in.-lbs. Use all 5 bolts with CO2T Adapter
4. Connect the oil supply line to the ¼ inch male flare
fitting and connect electrical leads in proper order.
5. Wire the OMB per instruction sheet PA-00301.
6. Assure there is proper oil level in the crankcase before
restarting the compressor.
Kit ACE, ACF and ACG
(ACE includes hex nut adapter and ACA adapter)
(ACF and ACG have rotolock fitting)
1. Assure that there is no pressure in the compressor
crankcase. Note the oil level and drain the crankcase
until it is below the level of the sight glass. Remove the
compressor sight glass. Install new PTFE washer on
the compressor.
2. ( ACE) install the large hex nut adapter on the
compressor and torque to 30-40 ft.-lbs. (ACF and ACG)
install the adapter rotolock fitting onto the compressor
and torque to 80 ft.-lbs.
3. ( ACE) Using PTFE tape as a sealant, thread the ACA
adapter into the large hex nut with the three hole flange
ring installed on the adapter. Torque the pipe thread to
30-40 ft.-lbs. Take care not to scratch the O-ring seal
surface of the adapter.
4, (ACG) Use the injector tube included in the adapter kit
instead of the injector tube provided with the OMB.
5. ( ACE, ACF and ACG) Using the O-ring and bolts provided,
install the OMB control unit to the adapter flange or end of
rotolock adapter (ACF and ACG). (Note: The three holes
are not equidistant, so make sure they are properly oriented
with the OMB mounting holes.) The top of the control unit
must be horizontal with the oil inlet fitting to the left. Torque
the bolts to 120 in.-lbs.

6. Connect the oil supply line to the ¼ inch male flare fitting
and torque to 120 in.-lbs. then connect the electrical leads
in the proper order.
7. Wire the OMB control per instruction sheet PA-00301.
8. Assure there is proper oil level in the crankcase before
restarting the compressor.
Kit ASA
(Includes bushing and ACA adapter)
1. Assure that there is no pressure in the compressor
crankcase. Note the oil level and drain the crankcase
until it is below the level of the sight glass. Remove the
compressor sight glass and PTFE washer. Take the PTFE
washer that was removed and place within the sight glass
groove in the compressor.
2. Install the bushing into the compressor and torque to
30-40 ft.-lbs.
3. Using PTFE tape as a sealant, thread the ACA adapter into
the bushing with the three hole flange ring installed on the
adapter. Torque the pipe thread to 30-40 ft.-lbs. Take care
not to scratch the O-ring seal surface of the adapter.
4. Using the O-ring and bolts provided, install the OMB control
unit to the adapter flange (Note: The three holes are not
equidistant, so make sure they are properly oriented with
the OMB mounting holes.) The top of the control unit must
be horizontal with the oil inlet fitting to the left. Torque the
bolts to 120 in.-lbs.
5. Connect the oil supply line to the ¼ inch male flare fitting
and torque to 120 in.-lbs. then connect the electrical leads
in the proper order.
6. Wire the OMB control per instruction sheet PA-00301.
7. Assure there is proper oil level in the crankcase before
restarting the compressor.
