7. Test run
7.1. Before test run
After completing installation and the wiring and piping of the indoor and
outdoor units, check for refrigerant leakage, looseness in the power
supply or control wiring, wrong polarity, and no disconnection of one
phase in the supply.
Use a 500-volt megohmmeter to check that the resistance between the
power supply terminals and ground is at least 1.0 MΩ.
7.2. Test run
Refer to the installation manual that comes with each remote controller for details.
7.3. Self-check
Refer to the installation manual that comes with each remote controller for details.
RF thermostat is not established.
