A1: Selection requires the target evaporating and condensing temperatures, required cooling capacity, electrical power supply specifications, and target refrigerant type.
A2: Ensure system pipework is pressure-tested, clean, and fully evacuated, and confirm that the crankcase heater has warmed the lubrication oil adequately prior to startup.
A3: The integrated INT69VS electronic protection module continuously monitors winding temperatures, initiating a safety trip if overheating or electrical irregularities occur.
A4: Periodically inspect oil level and clarity through the sight glass, verify electrical terminal tightness, check suction strainer cleanliness, and log running current values.
