9.4 Safety And Leakage Check
Electrical safety check
Perform the electrical safety check after
completing installation. Cover the following
areas:
1. Insulated resistance
The insulated resistance must
be more than 2MΩ.
2. Grounding work
After finishing grounding work,
measure the grounding resistance
by visual detection and using the
grounding resistance tester. Make
sure the grounding resistance is less
than 4Ω.
3. Electrical leakage check (performing
during test while unit is on)
During a test operation after
completed installation, the use the
electroprobe and multimeter to
perform an electrical leakage check.
Turn off the unit immediately if
leakage happens. Try and evaluate
different solutions until the unit
operates properly.
Gas leak check
1. Soap water method:
Apply a soap-water solution or
a liquid neutral detergent on the
indoor unit connection or outdoor
unit connections with a soft brush to

10. TEST RUN

10.1 Before Test Run
A test run must be performed after the
entire system has been completely
installed. Confirm the following points
before performing the test:
a) The indoor and outdoor units are
properly installed.
b) Piping and wiring are properly
connected.
c) No obstacles near the inlet and outlet
of the unit that might cause poor
performance or product malfunction.
d) The refrigeration system does not leak.
e) Drainage system is unimpeded and
draining to a safe location.
check for leakage of the connecting
points of the piping. If bubbles
emerge, the pipes are experiencing
leakage.
2. Leak detector
Use the leak detector to check for
leakage.
Note: The illustration is for example
purposes only. The actual order of
A, B, C, D, and E on the machine may
be slightly different from the unit you
purchased but the general shape will
remain the same.

A, B,C,D are points for one-four type.
A, B,C,D, and E are points for the
one-five type.
f) The heating insulation is properly
installed.
g) The grounding wires are properly
connected.
h) Length of the piping and additional
refrigerant stow capacity have been
recorded.
i) The power voltage is the correct
voltage for the air conditioner.
CAUTION
Failure to perform the test run may
result in unit damage, property
damage or personal injury.
