Unobstructed Airow
Unobstructed airflow to and from the system is critical for the system’s overall performance and lifespan.
Registers must be unobstructed. The air blown by the fans needs to circulate and either dissipate or absorb heat from
the space. The system will operate more efficiently with a greater amount of air to exchange.
Door and Door Seal
An exterior-grade (1¾”) door must be installed as a cellar door. It is very important that weather stripping is attached
to all four sides of the doorjamb. A bottom “sweep” or threshold is also required. The door must have an excellent
seal to keep the cool cellar air from escaping the cellar. If the door is not sealed properly, the cooling system may run
continuously, shortening its operational lifespan.
In cases where glass doors are used and the room size is close to the recommended system size, the next larger size
WhisperKOOL system should be used. This will compensate for the insulation loss due to the lower insulation rating of
glass.
