A1: Required selection data includes target evaporating and condensing temperatures, total required cooling capacity, site electrical supply specifications, and the specified refrigerant type.
A2: Install oil equalization lines between multiple compressors, fit vibration isolators near suction and discharge connections, and ensure suction line sizing maintains proper oil return velocity.
A3: The motor protection module continuously monitors winding temperatures and power parameters, triggering an automatic safety shutdown if overheating or phase imbalance is detected.
A4: Periodically inspect oil level and clarity through the sight glass, verify electrical connection tightness, check suction strainer condition, and log operating currents during scheduled servicing.
