IMPORTANT
PLEASE READ BEFORE OPERATING YOUR
PROWLER LD 5000 LEAK DETECTOR
THE PROWLER EMPLOYS AN ULTRA SENSITIVE SENSOR AND AD-
VANCED SOFTWARE THAT IS CAPABLE OF FINDING TINY LEAKS IN
AC SYSTEMS.
THE PROWLER SOFTWARE AUTOMATICALLY DETECTS CHANGES
IN CONCENTRATION OF GAS. ONCE THE DETECTOR ALARMS, IT
WILL ALARM AGAIN ONLY WHEN THE CONCENTRATION OF RE-
FRIGERANT INCREASES.
TO VERIFY THE SOURCE OF THE LEAK, ALWAYS MOVE THE PROBE
AWAY FROM THE AREA OF THE LEAK TO ALLOW THE SENSOR TO
RESET TO A LOWER CONCENTRATION. THEN BRING IT BACK AGAIN
UNTIL THE EXACT LOCATION OF THE LEAK SOURCE HAS BEEN
VERIFIED.
If the source of the leak is very large, it may be necessary to pull away
from the leak for approximately 5 to 10 seconds to allow the sensor to re-
set again. The probe tip can then be brought back again to the area where
the alarm occurred to verify the source of the leak.
NOTE
: When searching for large leaks and large leaks in contaminated
areas always turn the PROWLER on and allow the detector to complete
the warm-up mode before entering the suspected work area. Wait an ad-
ditional 10 to 15 seconds to allow the sensor to reach maximum sensitivity
and select the sensitivity of the unit initially to HI sensitivity mode before
entering the work area. Change the sensitivity level to LO or MED if nec-
essary to locate the source of the leak. Before entering the work area, al-
ways validate and the sensitivity of the instrument with the Leak Test Vile.
WARNING: In a contaminated work area, the PROWLER will automat-
ically reset (stop alarming) even though refrigerant contamination is
present. If the PROWLER alarms when entering the work area, check
the LCD display. If you see 10 full bars, the background contamina-
tion is dangerously high (excess of 1,000 ppm) and it is not a safe
condition. The work area needs to be ventilated before continuing.
