This procedureis finished.<1 MΩ Insulation resistance is not OK. Go to thenext step.2 Turn ON the power and leave it on for 6 hours.Result: The compressor will heat up and evaporate anyrefrigerant in the compressor.3 Measure the insulation resistance again.4 CommissioningNOTICENEVER operate the unit without thermistors and/orpressure sensors/switches.
