Things To Check After Completing The Installation - Samsung DVM S AM MXVAFC Series Installation Manual

Things to check after completing the installation

1. Before supplying the power, use DC 600 V (AM✴✴✴✴XVAF✴) insulation resistance tester to measure the power (3
phase: R, S, T) terminal and the outdoor unit grounding.
- Measurement should be over 30MΩ.
2. Before supplying the power, use a voltmeter and phase tester to check the voltage and the phase.
- R, S, T terminal: Check the 230V (AM✴✴✴✴XVAF✴) between wires (R-S, S-T, T-R)
Never measure the communication terminal since communication circuit may get damaged.
Check for short-circuit of the communication terminal with a general circuit tester.
CAUTION
3. Check if the R-410A indoor units are connected.
