Electrical and Gas Leak checks.
Gas Leak checks
Prior to the test run check for gas leaks using the following methods:
Soap and water method
Using a soft brush, apply soapy water or liquid detergent to all pipe connection points on the
indoor and outdoor unit. The presence of bubbles indicates a leak. Repairs must be made
prior to test running the unit.
Leak Detector method
If using a leak detector, refer to the device’s operation manual for proper usage instructions.
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 the test run:
Check earthing
Measure earthing resistance. The earthing resistance must be less than required to trip any
protection devices.
Perform an insulation resistance test.
During the test run:
Check for electrical leakage, using a low current tong meter.
