Do not operate the compressor without enough system
charge to maintain at least 55 psig (3.8 bar) suction
pressure. Do not operate with a restricted suction or
liquid line. Do not operate with the low pressure cut-out
disabled.
Allowing suction pressure to drop below 55 psig (3.8
bar) for more than a few seconds may overheat the
scrolls and cause early drive bearing damage. Never
install a system in the field and leave it unattended with
no charge, a holding charge, or with the service valves
closed without securely locking out the system. This
will prevent unauthorized personnel from accidentally
ruining the compressor by operating with no refrigerant
flow.
