WARNING

Failure to correctly install the cap onto the purge vent port will result in exces-

sive 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 the 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 of the refrigerant transfer and pro-

vides 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" SAE female 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 of the refrigerant transfer and provides containment

up to 300 psig. The outer tube provides protection of the inner tube from abrasion, nick-

ing, 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 proce-

dures. 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.
