Power Connection
See the serial tag on the side of the unit or the “Specifications” section for electrical
specifications.
For Models 3906 and 3943, plug the provided 10 ft. power cord with the CEE 16 A, 6h
plug into the grounded dedicated electrical circuit.
Installing the Shelves
The shelves may be installed at any level in the environmental chamber. Install a shelf
channel on each side. With the tabs pointing up, attach the channel by locating the rivet
into a slotted hole, far end first. Pull the channel toward the front and slide the front rivet
on the channel into the slotted hole and press down. Make sure that the channels are
opposite each other so that the installed shelf will be level.

Leveling the Unit
Place a bubble-type level on a shelf inside the environmental chamber. Adjust the feet as
needed; counterclockwise to lengthen or clockwise to shorten. Level the unit
front-to-back and left-to-right.
Connect Water Inlet for Humidity System
The humidity reservoir will require approximately three cups (0.710 liter) of water on the
initial filling. For best operation of the environmental chamber, sterilized distilled,
demineralized or de-ionized water should be used in the humidity reservoir. Water purity
should be in the resistance range of 50K to 1MOhm*cm, or a conductivity range of 20.0 to
1.0
S/cm. Refer to ASTM Standard D5391-93 or D4195-88 for measuring water purity.
Distillation systems, as well as some types of reverse osmosis water purity systems, can
produce water in the quality range specified. Tap water is not recommended as it may
contain chlorine, which can deteriorate the stainless steel. Tap water may also have a
high mineral content, which would produce a build-up of scale in the reservoir. High purity
or ultrapure water is not recommended as it is an extremely aggressive solvent and will
deteriorate the stainless steel. High purity water has a resistance of above 1M to 18M
Ohm*cm. Even high purity water can contain bacteria and organic contaminants. Water
should always be sterilized or treated with a decontaminant, safe for use with stainless
steel as well as safe for the product, prior to being introduced into the humidity reservoir.
