Initial setup and water fill
Distilled water is recommended for trouble-free operation. Always
add water with the power turned off (the water level may pulse up
and down during normal operation). After the water chamber has
been filled (or refilled), allow sufficient time (typically one hour) to
equilibrate the water temperature.
1. Set up the unit on a flat surface.
2. Pour in one gallon of clean distilled water.
3. Install the drain line in the rear drain port, and drain out
enough water (about one cup) to ensure that the drain line is
full of water. This procedure is needed for proper water level
indication.
4. Remove the drain line and pour in an additional 1
¼
gallons of
distilled water. Wipe up any spillage.
5. Install the dry line, connecting to a source of dry air, if avail-
able (–40°C DP dry air or nitrogen, 15–16 psig, 4–5 l/m flow).
If running from a desiccant cartridge, make sure the cartridge
is fully seated and the desiccant color is a minimum of 75%
blue throughout the length of the tube. Replace the cartridge
or desiccant if necessary.
6. Install the unit’s cover.
7.
Install the power cord and turn the unit on. Set the controller
to 80–90% RH.
8. Check the water fill level indicator and make sure the level
has not increased above the fill line and that the overflow line
does not leak water (front left-hand corner of unit). If the
water fill level rises sharply or the overflow tube leaks, check
the wet gas tube inlet ports for obstructions.
9. Run the unit for 15–30 minutes and inspect for the absence of
water in the bottom of the wet line ports located at the bot-
tom of the tank I/O block (near 1111H sensor). If water is
present, soak it up with a cotton swab or absorbent cloth, nap-
kin or towel.
10. Perform mirror cleaning and balance procedure as described
