Page 32: Trial Operation And The Performance
Trial operation and the performance 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. - Page 33 Trial operation and the performance 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 * .
