A1: To determine exact suitability, please provide your required cooling capacity, operating evaporation and condensation temperatures, power supply standards, and target application details.
A2: System lines must be thoroughly pressure-tested, evacuated, and checked for cleanliness, while ensuring the crankcase heater has warmed the lubrication oil sufficiently before starting the motor.
A3: The built-in INT69VS protection module monitors winding temperature and power conditions, automatically triggering a safety shutdown if overheating or phase irregularities occur.
A4: Technicians should periodically verify oil level and clarity through the sight glass, inspect suction filter cleanliness, and log operating currents to detect system abnormalities early.
