ELECTRICAL AND GAS LEAK CHECKS
TEST RUN
ELECTRICAL SAFETY CHECKS
After installation, confirm that all electrical wiring
is installed in accordance with local and national
regulations, and according to the Installation Manual.
BEFORE TEST RUN:
CHECK GROUNDING WORK
Measure grounding resistance by visual detection
and with grounding resistance tester. Grounding
resistance must be less than 4.
BEFORE TEST RUN
Only perform test run after you have completed the
following steps:
• Electrical Safety Checks – Confirm that the unit’s electrical
system is safe and operating properly.
• Gas Leak Checks – Check all flare nut connections and
confirm that the system is not leaking.
• Confirm that gas and liquid (high and low pressure) valves
are fully open.
TEST RUN INSTRUCTIONS
You should perform the Test Run for at least 30 minutes.
• Connect power to the unit.
• Press the ON/OFF button on the remote control to turn
it on.
• Press the MODE button to scroll through the
following functions, one at a time:
a) COOL – Select lowest possible temperature.
b) HEAT – Select highest possible temperature.
• Let each function run for 5 minutes, and perform the
following checks in the chart to the right:
WARNING – RISK OF ELECTRIC SHOCK!
ALL WIRING MUST COMPLY WITH LOCAL
AND NATIONAL ELECTRICAL CODES, AND
MUST BE INSTALLED BY A LICENSED
ELECTRICIAN.
GAS LEAK CHECKS
There are two different methods to check for gas leaks.
SOAP AND WATER METHOD
Using a soft brush, apply soapy water or liquid
detergent to all pipe connection points on the indoor
unit and outdoor unit. The presence of bubbles
indicates a leak.
LEAK DETECTOR METHOD
If using leak detector, refer to the device’s operation
manual for proper usage instructions.
AFTER PERFORMING GAS LEAK CHECKS
After confirming that the all pipe connection points do
not leak, replace the valve cover on the outside unit.
DURING TEST RUN:
CHECK FOR ELECTRICAL LEAKAGE
During the Test Run, use an electroprobe and multimeter
to perform a comprehensive electrical leakage test.
If electrical leakage is detected, turn off the unit
immediately and call a licensed electrician to find
and resolve the cause of the leakage.
NOTE:
This may not be required for some locations in the US.
