The side access door is for the installation of a small dehumidifier (customer supplied). This is an optional addition to the cabinet. The standard air circulation fans will dry screens but at a slower rate. If the dehumidifier is equipped with a drain hose, use the optional drain nut to route the hose outside of the cabinet. The dehumidifier must be 110 VAC.
WHEN SHOULD YOU USE A DEHUMIDIFIER?
Ideally, the humidity in a darkroom should not climb higher than 40%. Not all shops need a dehumidifier in their drying cabinet. Ask yourself how dry the climate in your area is. Shops in dry climates like Arizona may not need a dehumidifier, since humidity is generally below 30%. Shops in humid climates such as Florida, where humidity is regularly above 60%, should invest in a dehumidifier.
NOTE: Max dehumidifier size for this drying cabinet is 14” wide x 7” deep x 14” High.
