Refrigerant Hoses — Four, l/2-in. refrigerant hoses
and 8 ball valves with couplers are factory supplied with
the RMS unit. See Table 1. The refrigerant hoses are used
to transfer liquid and vapor through the Refrigerant Man­
agement System. They are designed to withstand high vac­
uum pressure without collapsing.
When used with the refrigerant hoses, the ball valve and
coupler assembly prevent refrigerant loss. Connect the ball
valve and coupler assembly to each end of the 4 refrigerant
hoses. Hand tighten the ball valve and coupler assembly to
the refrigerant hose. The ball valve and coupler assembly
connect to the RMS unit or chiller, depending upon the type
of operation. The coupler should be hand tightened to the
RMS unit or chiller. Excessive tightening will damage the
rubber gaskets.
Liquid Indicator — The 1/2 in. liquid indicator (in line
sight glass) is factory supplied. Use the liquid indicator dur­
ing either the liquid refrigerant transfer or the vapor con­
densing process to determine the end point of the process.
When liquid is no longer visible in the glass, the process is
almost complete.
Filter Drier — The filter drier should be used to recycle
refrigerant. Use the factory supplied filter drier when re­
moving moisture and small particles from the refrigerant.
The filter drier is most effective when used with liquid re­
frigerant. The filter drier holds approximately .39 oz
(11 g) of water. See Table 4.
When cleaning large quantities of saturated refrigerant,
use a field supplied, replaceable core filter drier assembly.
The assembly should have four, 100 in.^ cores. It will re­
move approximately 4.2 oz (118 g) of water.
