Installation and Maintenance
The Breezaire WKSL 4000 is designed for easy installation by a qualified refrigeration service technician. The unit requires a mechanical line set (two copper tubes) to connect the two modules, and power is hard-wired to the units using an adequately sized 110 AC volt electrical source. During installation, the system must be charged with refrigerant, and the condensing unit must have a constant supply of fresh air, with an ambient temperature of less than 85°F. Regular maintenance is recommended to ensure optimal performance and longevity of the unit. This includes checking the refrigerant levels, cleaning the air filters, and ensuring that the airflow is not blocked. Proper installation and maintenance will help the Breezaire WKSL 4000 deliver reliable and efficient cooling performance for years to come.
Cooling Performance and Capacity
The Breezaire WKSL 4000 is designed to provide reliable and efficient cooling performance, with a maximum line set length of 50 feet. This unit is suitable for wine cellars up to 1000 cubic feet, ensuring consistent temperature control for your wine collection. One of the unique features of the Breezaire WKSL 4000 is the cold air up option, which allows the evaporator to be positioned lower down, closer to the floor, by re-positioning a cover plate on site. This flexibility in installation helps to optimize the cooling distribution within the wine cellar, ensuring that your wine is stored at the ideal temperature.
