Operating Instructions
1.
POWER ON:
The detector is turned ON and
OFF by pressing the POWER button (see
figure 1 below).
2.
WARM-UP:
The detector automatically starts
heating the sensor to condition it for use.
While in this WARM UP phase – and until
ready – the instrument will signal audibly by
beeping slowly and visually by flashing the
sensitivity LEDs and the zero (0) in the
SmartAlarm™ display window. Warm up time
is usually about 20 SECONDS or less.
3.
SEARCH:
The detector is ready for leak
searching when the sensitivity LEDs stop
flashing and the beep rate increases. At this
time the zero in the display window stops
flashing. When a leak is detected, the beeping
sound and flashing LED in the probe will
increase in frequency, and the SmartAlarm
digital LED display will turn on indicating the
leak size. If no leak is detected go to HI sensi-
tivity and continue searching.
SmartAlarm™ Display
The SmartAlarm LED Display is a digital leak size
indicator that numerically displays the leak size on a
scale of 1 to 9 for all HFC and HCFC refrigerants –
regardless of the sensitivity setting. This value helps
you decide whether or not the leak is large enough
to require repair.
For example, when in the HI sensitivity mode, the
detector may sound a full audio alarm but the Smar-
tAlarm Display may show a low number – indicat-
ing that the leak is very small. In contrast, when in
the LO sensitivity mode, a full audio alarm may not
sound but the SmartAlarm may show a high num-
ber, indicating that the leak is large.
The maximum value displayed, once the source of
the leak is located, indicates the leak size. This value
helps you decide whether or not a leak is large
enough to require repair. The table above shows the
leak rates corresponding to the SmartAlarm numeri-
cal display.
UV LIGHT OPERATION
Before leak checking with the UV light:
(a) Make sure the A/C system is properly charged
with sufficient dye (see manufacturer
’
s specifi-
cations for proper dye charge.)
(b) Run the A/C system long enough to thoroughly
mix and circulate the dye with the refrigerant
and lubricating oil.
1.
Turn on UV light by pressing the UV light
ON/OFF button (see diagram on left).
2.
Holding the leak detector approximately 10” to
14” away, shine the UV light beam slowly
over the components, hoses, and metal lines
that make up the A/C system.
3.
When the UV light shines on the fluorescent
dye that has escaped from the system, the dye
will glow a bright yellow green.
4.
The UV LEDs will automatically turn off after
five minutes.
