Important: Ensure that there is no secondary power
source connected to the compressor
before disconnecting the I/O cable.
7. Disconnect the I/O cable from the Backplane I/O
connector (J7) and remove the cable from the
compressor.
8. Reinstall the Service Side Cover.
9. Once the transfer of refrigerant is complete, bring the
compressor back to atmospheric pressure according to
industry standards using dry nitrogen.
10. Disconnect the compressor from the refrigerant system
connections (suction, discharge, economizer and motor
cooling line), taking care when removing connections
that there is no residual pressure.
11. Reinstall the Mains Input Cover.
12. Remove the four compressor mounting bolts and
associated hardware.
13. Connect an appropriate lifting device to the eyebolts
provided on each side of the compressor and remove
compressor.
14. Using the blanking plates and bolts provided with the
new compressor, seal the compressor and charge to 25
psi with inert gas for shipment (this will prevent
moisture and foreign material from entering the
compressor).
Compressor Installation
WARNING
Hazardous Voltage!
Failure to disconnect power before servicing could
result in death or serious injury.
Disconnect all electric power, including remote
disconnects before servicing. Follow proper lockout/
tagout procedures to ensure the power can not be
inadvertently energized. Verify that no power is
present with a voltmeter.
ARTC-SVX013A-EN
Note: Blanking plates should not be removed from the new
compressor until you are ready to place the new
compressor in position. New compressors are
pressurized with inert gas to 50 psi. Pressure should
be relieved through the Schrader valve, located next
to the motor cooling connection, prior to removing
the blanking plates.
1. Inspect the compressor to ensure all connections and
fasteners are correctly installed.
2. Relieve the inert gas pressure through the motor
cooling Schrader valve.
3. Remove the suction, discharge and economizer (if
applicable) blanking plates from the new compressor.
4. Remove the motor cooling inlet adapter cap.
5. Mount the compressor in position and install the rubber
mounts and hardware.
6. Attach all refrigerant line connections to the
compressor using the new O-rings supplied with the
compressor.
7. Tighten the economizer flange bolts (if applicable).
8. Tighten the discharge flange bolts.
9. Tighten the motor cooling line connection.
10. Tighten the suction flange bolts.
11. Remove the Service Side Cover.
12. Connect the compressor I/O cable to the Backplane.
13. Remove the Mains Input Cover.
14. Connect the cable gland that secures the Mains Input
cable conduit to the Mains Input bracket.
15. Install the Mains Input ground wire to the ground post.
16. Attach the AC mains cables to the terminals.
17. Re-install the Mains Input Cover.
18. Leak test the compressor to appropriate pressure and
industry accepted standards.
19. Evacuate compressor to appropriate pressure and
industry accepted standards.
20. Charge the compressor with refrigerant.
21. Apply power to the compressor.
