    10. Trial Operation 5-minute delay function ■ If starting up the unit after being powered off, the compressor will run about 5 minutes later against being damaged. Cooling/heating operation ■ Indoor units can be controlled individually, but cannot run in cool and heat mode at the same time. If the cool mode and the heat mode are existing simultaneously, the unit set latter will be standby, and the unit set earlier will run normally.

  • Page 44: Heating Capacity

    Heating capacity ■ The heating mode adopts the heat pump type that absorbs outdoor heat energy and releases into indoor. So if outdoor temperature goes down, the heating capacity will decrease. Trial operation ■ Before trial operation: Before being energized, measure the resistor between power terminal block (live wire and neutral wire) and the grounded point with a multimeter, and check if it is over 1M * .
