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.
The water inlet is the 1/8” FPT connection located on the rear top center of the
environmental chamber. For pressurized systems, water inlet pressure must not exceed
40 PSI. A manual shut-off valve should be installed between the main water supply and
the environmental chamber. A water strainer is provided that can be connected to the
back of the cabinet if desired.
Alternate Water Supply for Humidity System
If an in-house water supply of the required purity range (50K to 1M Ohm*cm) is not
available, an alternate water supply method can be used. A large vented carboy (5 gal.
minimum) of water in the required purity range can be placed on top of the unit. The
provided ¼” hose barb fitting should be used to connect to the 1/8” FPT water inlet fitting,
located on the rear top center of the environmental chamber.
NOTE
Thermo Fisher Scientific offers free water sample testing. For further
information contact our Customer Service Department.
Distilled or de-ionized water used in humidity reservoir must be within a water
quality resistance range of 50K to 1M Ohm*cm to protect and prolong the life of
the stainless steel. Use of water outside the specified range will decrease the
operating life of the unit and may void warranty.
To prevent mineral buildup on humidity generator walls, it may be necessary to
clean the humidity generator with a non-metallic abrasive pad and flush
thoroughly every two to three months. Refer to
