Gas Leak Checks
There are two dierent methods to check for

for the critical points to check for leaks.
Soap and Water Method
Using a soft brush or spray bottle, apply a
soapy water solution to all of the pipe con-
nection points of the indoor and outdoor
units, watching to see if any bubbles form.
The presence of bubbles indicates there is a
leak.
Leak Detector Method
If using a leak detector, refer to the device' s
operation/instruction manual for proper
usage instructions.
BEFORE TEST RUN
Check Grounding Work
Measure grounding resistance by visual
detection and with a grounding resistance
tester. Grounding resistance must be less
than 0.1Ω.
DURING TEST RUN
Check for Electrical Leakage
During the Test Run, use an electroprobe and
multimeter to perform a comprehensive
electrical leakage test.
NOTE: This may not be required for some
locations in North America.
