WARNING
Failure to correctly install the cap onto the purge vent port will result
in excessive loss of refrigerant during the refrigerant identification
procedure, which is a health hazard. The instrument ALWAYS performs
a refrigerant identification before permitting an air purge procedure.
Printer Port
The printer port is a 25-pin connector used to download results of sample analysis to a user-
supplied printer through a user-supplied cable. The port supports most parallel port printers.
R-12 Sample Hose
The 6-foot (1.8 meter) R-12 sample hose is constructed of a nylon inner tube and a
polyurethane outer tube. The inner tube handles all refrigerant transfer and provides
containment up to 300 psig. The outer tube provides protection of the inner tube from
abrasion, nicking, cutting, etc. The hose is provided with an instrument inlet port mating
connector on one end and a 1/4 in. SAE internal flare coupling.
R-134a Sample Hose
The 6-foot R-134a sample hose is constructed of a nylon inner tube and a polyurethane
outer tube. The inner tube handles all refrigerant transfer and provides containment up
to 300 psig. The outer tube provides protection of the inner tube from abrasion, nicking,
cutting, etc. The hose is provided with an instrument inlet port mating connector on one
end and an R-134a low-side coupler on the service end.
Hardware Descriptions
Purge Vent Port
The purge vent port emits a mixture of refrigerant vapor and air during
purging procedures. The port is supplied with a protective cap that must be
replaced with the purge vent hose during purging operations. The cap must
remain installed on the port during refrigerant identification procedures to
avoid excessive losses of refrigerant.
