Chapter 1 — Installation and Initial Setup
A. Dry air in. A dry air supply can be connected to this port. The
dew point of the dry air must be at or below –40°C for proper
full-range operation. The flow rate requirement is
1 to 2 psig at 5
liters per minute (minimum)
. If a dry air supply is not available,
then this port must be left open to the atmosphere. The internal
pump will draw the ambient air through the desiccant cartridge to
supply the HumiLab with the proper supply of dry air.
B. Coolant In. For optimum performance, an optional temperature
bath/circulator should be connected to provide a stable water and
chamber temperature. Connect the chiller’s output port to this
Coolant In port.
C. Coolant Out. Connect the temperature bath/circulator’s input port
to the coolant-out port of the HumiLab.
D. Drain. This port allows the operator to easily drain the saturator
before transporting or storing the unit. Simply place a 1/4” tube
into a bucket and press the other end into the drain fitting until it
stops. Water will immediately begin to drain into the bucket. To
remove the tube from the fitting, depress the black outer ring and
pull out the tubing. A built-in check valve prevents water from
running out of the drain port when the tubing is not in place.
Coolant
connections
The HumiLab is equipped with 1/4” “instant on” coolant fittings
that require no tools for installation. These fittings will accept many
types of hard-wall tubing such as Teflon, stainless steel, or
Impolene. To insert the tubing, simply press the tubing into the
connector as far as it will go. Pull gently on the tubing to ensure
the connections are secure.
To remove the tubing from the “Instant On” fittings, simply depress
the black outer ring and pull the tubing out. The coolant fittings
are equipped with built-in check valves that enable the operator to
easily remove the coolant lines with minimal fluid loss.
If the optional chiller is used to accurately control the chamber
temperature, connect the chiller output to the “Coolant In” fitting
on the HumiLab and connect the chiller inlet to the “Coolant Out”
fitting.
