16009 DiscovR R134a Refrigerant Identifier 3
Safety Precautions cont’d
CAUTION: To prevent equipment damage,
•
Brass Filter: This instrument is equipped with a brass filter located
at the outlet of the R134a coupler. This filter significantly reduces
the possibility of oil contamination in the unit. Replace this filter
when oil is detected in the hose near the coupler, or when the unit
indicates “Excess Air / Fail”. Failure to replace the filter when so
indicated may result in “out-of-warranty” damage to the instrument.
•
Sample Input: This instrument requires connection of the sample
hose to the low-side, or vapor, port of the source vehicle or refriger-
ant cylinder. Connection of the sample hose to the high-side, or
liquid, port of the source vehicle or refrigerant cylinder will result in
“out-of-warranty” damage to the instrument. Additionally, the low-
side, or vapor, port shall not emit sample gas in excess of 300 psig
or sample gas that contains oil or liquids.
•
Sample Hose: Inspect the sample hose before and after each use
of the instrument. Immediately replace the hose if it appears cracked,
obstructed, or fouled with oil.
•
Never use a sample hose other than those approved for use with
the Identifier. The use of other hose types may introduce errors
and excessive refrigerant loss.
•
Verify the refrigerant source to be tested will not emit oil or liquid
refrigerant before connecting the Identifier sample hose.
•
Never connect the Identifier to any refrigerant source that exceeds
300 psi pressure.
•
Do not use the coupling supplied on the Identifier R-134a sample
hose for any purpose other than Identifier sampling. The coupler
supplied on the R-134a hose does not contain check valves and
will continually vent refrigerant.
•
Never obstruct the sample exhaust or air intakes—located on the
front and top of the instrument—during use of this tool.
•
Do not throw, drop, immerse in liquid, or mistreat the instrument.
•
Store the instrument in its storage case when not in use.
•
Maintain the cleanliness of the instrument to prevent contamination
and prolong its life.
