Installation Location
The chamber will produce a moderate amount of heat during normal operation. Locate the
chamber in an area with adequate ventilation to prevent excessive heat build-up. The chamber
must be on a solid and level surface that is rated to hold at least 350 pounds.
! CAUTION: The minimum clearance you should allow for proper ventilation around the
chamber must be at least 6" from both the left and right side, and 12" from the
rear.
! CAUTION: This chamber is designed for operation in a conditioned laboratory
environment. Operation above 30°C (85°F) or below 16°C (60°F) ambient
room temperature is NOT recommended.
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. 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
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.
