Condensate Drain
The condensate drain connection is located on the rear of the chamber. This provides a way to
remove condensate that may accumulate on the evaporator (cooling coil) during temperature
cycling or when the refrigeration system runs to maintain moderate temperatures.
Any time the ambient air is subjected to temperatures below the dew point, moisture will
condense out of the air. The effect is ice or frost during low temperature operation. When the
chamber is heated above 0°C or the cooling system turns off, the ice or frost will turn into water.
The drain fitting accommodates a 1/4-inch male pipe thread. Right angle and straight barbed
adapters are provided so you can easily connect 3/8-inch I.D. flexible tubing to it. The chamber
drain water is not under pressure and is fed by gravity. Therefore, it must empty into a container
or open floor drain. Alternatively, the chamber drain can empty into a condensate pump. You can
purchase a condensate pump from suppliers such as Grainger (www.grainger.com).
Under most circumstances, you will not see any water coming out of the drain.
Reversible Chamber Door (Model 107 only)
The chamber door can be mounted to open from the left or right side. The chamber cabinet has
mounting holes on both sides for the hinges and door latch. If you reverse the door, see “How to
inspect the door seal” in the Maintenance chapter of this manual to make sure the hinges and
door latch are adjusted correctly.
