On low pressure chillers, moisture typically enters the refrigerant system through
air leaks from areas with gaskets or fittings
The maximum test pressure for leak testing a low pressure centrifugal is: 10 psig
Leak test and repair the chiller to reduce refrigerant loss from a pruge unit on CFC-
11 chiller
...
A hydrostatic tube test kit is used to:
determine if a tube leaks
Commercial and industrial process refrigeration systems must be repaired when the
leak rate exceeds of the charge per year.
35%
Refrigerant recovery typically start,
with liquid recovery it is faster.

psig
According to ASHRAE Guideline 3-1996, if the pressure in a system rises from 1
mm Hg to a level above during a standing vacuum test, the system should be
checked for leaks.

According to the EPA there is approximately refrigerant vapor left in an
average 350 ton R-11 chiller at 0 psig pressure once all the R-11 liquid has been
removed.
100 pounds
Charging refrigerant liquid into a refrigeration system when it is under a 29 inch
Hg vacuum can cause the:
system water to freeze
A system does not have to be evacuated all the way to the required level when:
leaks in the appliance make evacuation to the prescribed level unattainable Which
of the following repairs would ALWAYS be considered "major" under EPA's
replacement of evaporator coil
Under EPA's regulation's is used to pressurize a low pressure chiller for the
purpose of opening the system for a non-major repair?
