Hardware Descriptions
The Identifier provides the user with a complete tool to identify refrigerant mixtures, and
rid the mixtures of air contamination, all housed in a portable, rugged carrying case.
Housing
The instrument is housed in a rugged, hand-held, injection-molded nylon case. The case
houses the sensing devices, the plumbing system, and the electronics of the instrument.
Power Cord
A nine-foot (2.75 meter), molded, three-prong, grounded, NEMA, power supply cord
is attached directly to the instrument. Different power cords may be supplied if the
instrument is to be used in areas outside North America.
Sample Filter
The sample filter provides retention of particulate and oil mist suspended within the
sample vapor. The filter is supplied with a red, maintenance-indicating dye. As soon as
red spots or discoloration begin to appear anywhere on the white outside diameter of the
filter element, THE FILTER MUST BE REPLACED. Failure to replace the filter when
indicated may lead to severe instrument damage not covered under warranty repairs.
Air Intake Port
The air intake port is located at the top of the instrument and provides the entry point for
ambient air into the instrument during calibration procedures. Never obstruct the port
during use of the instrument.
Sample Exhaust Port
The sample exhaust port, located on the bottom edge of the instrument, will emit spent
sample gasses. Keep this port clear and unobstructed during use.
Sample Inlet Port
The sample inlet port admits refrigerant vapor into the instrument through the connection
of the mating end of the sample hose.
System Pressure Gauge
The system pressure gauge indicates to the user the presence of a refrigerant sample flow
into the instrument.
