TESTING SYSTEM FOR LEAKS N24FFA8
A leak is likely to occur where two components are connected
together. See illustration for possible locations.
The Leak Detector Torch is a butane gas-burning torch used to
locate a leak in any part of the refrigeration system. Refrigerant
gas drawn into the sampling or “sniffer” hose will cause the flame
to change color in proportion to the size of the leak. A very small
leak will produce a flame varying from yellowish-green to bright
green. A large leak will produce a brilliant blue flame.
Caution
Do not use the lighted detector in any place where explosive
gases, dust or vapors are present. Do not breathe the
fumes
that are produced by the burning of refrigerant gas. Large
concentrations of refrigerant in the presence of a live flame
become dangerously toxic.
If the flame remains bright yellow when the tester is removed
from a possible leak point, insufficient air is being drawn in through
the sampling tube, or the copper reaction wire is dirty.
(1) Assemble leak detector as shown be sure detector is seated
tightly over torch gasket.
(2) Holding torch upright screw-in butane charger (clockwise) until
punctured. (Do not use force).
(3) Screw-out butane charge (counterclockwise) about l/4 turn.
(4) Point torch away from body-then light escaping gas with
match. Always keep torch in upright position.
(5) Adjust flame by turning cartridge in or out as required.
(6) Allow 30 seconds to heat copper reaction wire.
Caution
Never remove butane charger while torch is lighted or in the
presence of any open flame.
(7) Examine all tube connectors and other possible lead points by
moving the end of the sampling hose from point to point.
Always keep torch in upright position. Since R-12 is heavier
than air, it is good practice to place the open end of sampling
hose directly below point being tested. Be careful not to pinch
sampling tube since this will shut off air supply to flame and
cause a color change.
(8) Watch for a change in the color of the flame. Small leaks will
produce a green color and large leaks a bright blue color. If
leaks are observed at tube fittings, tighten the connection,
using the proper flare wrenches, and retest.
