FAQ

What is the significance of the L35 L35 and L35 L50 cooling output ratings?

Answer: These ratings indicate the cooling performance under specific ambient (external) and enclosure (internal) temperature conditions. L35 L35 means an external temperature of 35 deg C and an internal temperature of 35 deg C. L35 L50 refers to an external temperature of 35 deg C and an internal temperature of 50 deg C. The unit provides different cooling power at these setpoints.

Can this unit be used with a 230V single-phase power supply?

Answer: No, this specific model SK 3304540 is designed exclusively for 3-phase power systems, specifically 400V at 50Hz or 460V at 60Hz. Attempting to connect it to a different voltage or phase configuration will damage the unit.

What maintenance is required for the R134a refrigerant in this unit?

Answer: The SK 3304540 is a hermetically sealed unit, meaning the refrigerant circuit is factory-sealed and should not require routine topping up. Maintenance should focus on keeping the condenser and evaporator coils clean and ensuring unobstructed airflow. Any work on the refrigerant circuit must be performed by a certified technician.
