Safety Precautions
Caution : To prevent equipment damage,
•
Air Detection Warm-Up: For best accuracy in air detection only, allow the instrument an
additional 5-minute warm-up period after completion of the warm-up and calibration modes.
Allow the instrument to sit undisturbed for 5 minutes following the completion of the initial
calibration mode.
•
Refrigerant Blend: As of December, 1996, there are nine (9) EPA SNAP “acceptable for use”
refrigerants that are available and legal for use as R-12 substitutes. The Identifier does not
identify any of the substitutes as pure R-12 or pure R-134a. Each of the nine blends has been
tested in the factory laboratory and none are able to “fool” the Identifier. Should one of the
blends be encountered, the Identifier fails the refrigerant and provides an analysis in terms
of percentage by weight concentrations of only R-12, R-134a, R-22, and hydrocarbons. Due
to cross-sensitivity issues of the blends on the sensing device, the resultant reading will not
be correct in the analyzed concentrations. However, the Identifier never identifies any of the
blends as pure R-12 or R-134a.
•
Sample Filter: Replace the sample filter on the instrument AS SOON AS RED SPOTS OR
DISCOLORATION APPEAR ON THE OUTSIDE DIAMETER OF THE WHITE ELEMENT. Failure
to correctly maintain and replace the sample filter will result in severe damage to the unit.
•
Sample Input: The instrument requires connection of the supplied sample hose to the
LOW-SIDE or VAPOR port of refrigerant storage cylinders or vehicle air conditioning
systems. Do NOT attempt to introduce liquid or samples that are heavily laden with oil into
the instrument. Do NOT connect the sample hose to the HIGH-SIDE or LIQUID PORT. Liquid
or oil laden samples cause severe damage to the instrument. ALWAYS verify the refrigerant
to be tested does not contain or will not emit heavy loads of oil or liquid.
•
Air Purge: Do NOT attempt to purge the detected air from refrigerant sources that are vapor
only. In order to purge air from refrigerant sources, there MUST be some quantity of liquid
refrigerant present to replace the volume of the air. Attempts to purge the air from vapor-only
sources will result in the loss of the entire refrigerant charge.
•
Inspect the sample hose before each use. Replace the hose if it appears cracked, frayed,
obstructed, or fouled with oil. Do NOT use hoses other than those supplied with the
instrument. The use of other hose types will introduce errors into the refrigerant analysis
and instrument calibration.
•
Do NOT open the instrument housing. There are no serviceable components internal to the
instrument, and opening the housing will void the warranty.
•
Place the Identifier on a flat and/or sturdy surface or utilize the housing hanging hook.
•
NEVER admit any sample into the instrument at pressures in excess of 300 psig.
•
Do not use the coupler supplied on the service end of the R-134a sample hose for any
application other than with the instrument. The coupler is modified, does not contain a check
valve, and is not suitable for any other refrigerant application.
•
Never obstruct the air intake, sample exhaust, or vent ports of the instrument during use.
