6.11 Leak Detection
IF A LEAK IS SUSPECTED, VENTILATE THE
AREA AND ENSURE THERE ARE NO NEARBY
IGNITION SOURCES.
Isobutane (R-600a) is a low pressure refrigerant
(30 PSIG @ 70°F). If checking for a leak, the
system should be at a minimum temperature of
70°F.
Use an isobutane (R-600a) compatible electronic
leak detector, check all joints, tubing and coils
for leaks. If a leak is detected, replace the
refrigeration module (
