Connecting the Drain
The incubators control humidity by injecting water only as needed. This eliminates
standing water which is a primary source of contamination and corrosion. There are
several ways to take advantage of this feature. The simplest method is to connect the
drain fitting and tubing supplied with the incubator to a local floor drain. During
operation, any water that is not evaporated inside the cabinet will be sent to the cabinet
drain to avoid standing water, minimizing the risk of contamination and corrosion.
If a floor drain is not available, CARON offers a water recirculation system accessory
(CRSY102) that acts as both a water supply and a drain for humidified incubators. This
system continuously recycles any excess water not needed by the incubator, filters and
conditions it, and reuses it to control humidity.
If neither a floor drain, nor a CRSY102 are available, another option is a carboy for a
water source and a plug in the interior incubator drain. While this solution is not
recommended due to the creation of standing water in the bottom of the incubator, it will
allow the incubator to control humidity, with some limitations, while not requiring a drain.
BOTL101 is a carboy accessory that can be purchased through CARON. A drain plug
is provided in the shipping kit for each incubator. When the interior drain is plugged, at
humidity levels above 80%, water can condense on the door, filling up the drain pan
located below the door.
When using a pressurized water source, failure
to connect the unit to a drain could result in
facility flooding.
The drain line relies on gravity to remove water
from the chamber. The drain line must remain
below the chamber to drain properly. Kinks or
elevations in the drain line above the cabinet
drain will not allow the chamber to drain.
