SGC/SGX ROTARY SCREW COMPRESSOR
INSTALLATION
HOLDING CHARGE AND STORAGE
SGC/SGX compressors are pressure and leak tested at the
Johnson Controls–FRICK factory and thoroughly evacuated
and charged with dry nitrogen to ensure integrity during ship-
ping and short term storage prior to installation.
Keep all compressors in a clean, dry location to prevent cor-
rosion damage. For compressors stored for more than two
months, check the nitrogen charge periodically (see General
Information for complete instructions).
Warning
Holding-charge shipping gauges (if mounted) are rated
for 30 psig and are for checking the shipping charge
only. They must be removed before pressure testing and
operating the system. Failure to remove these gauges
may result in catastrophic failure of the gauge resulting
in serious injury or death.
Caution
This equipment has been pressurized with
nitrogen gas. Temporary valves & gauges have been
installed.
1. Relieve pressure prior to opening lines or making
eld connections.
2. Remove charging valves or gauges prior to pressur-
izing system.
3. See installation, operation, and maintenance manual
for additional information.
Escaping gas may cause injury
RIGGING AND HANDLING
The compressor can be moved with rigging, using a crane
or forklift, by hooking into the two lifting rings at each end
of the main housings. Only use the compressor lifting rings
to lift the compressor itself. See Figures 10 to 12.

FOUNDATION
Each SGC Rotary Screw Compressor is shipped mounted
on a wooden skid. Remove before installing the unit.
Caution
Allow proper spacing for servicing (see Dimensional
Outline Drawings, Figures 3 to 11).

Screw compressors are capable of converting large quanti-
ties of shaft power into gas compression in a relatively small
space. The compression process creates relatively high
frequencyvibrationsthatrequiresufcientmassinthebase
to effectively dampen them.
The best insurance for a trouble free installation is to
rmlyanchorthecompressortoasuitablefoundation
using proper bolting and by preventing piping stress from
being imposed on the compressor.
