Chapter 1 — Installation and Initial Setup
Inst
allation
Place the
Humilab at its
operating site
Carefull
y 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.
Connect
a dry
gas source
(optional)
A dry gas source can be utilized to impro
ve 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.
Gas r
equirements.
If a dry gas source is used, the frost point should
be –40°C or lower for operation over the full specified range.
