Carefully move the Humilab to its intended site. Leave enough
room behind the unit to make the necessary gas, drain, and
optional chiller connections on the back panel. The two data cables
(an RS-232 cable and an analog output cable) can also be installed
at this point.
A dry gas source can be utilized to improve the longevity of the
desiccant material and provide the user with less frequent desic-
cant replacement.
The HumiLab does not require an external dry gas source to
operate. The unit is equipped with a desiccant cartridge that
provides the Humilab with a –40°C dew point dry gas. The unit is
designed to operate for approximately 24 hours of continuous
usage (at an ambient humidity less than 50%) before having to
replace the desiccant.
