CAUTION:
The humidity system must be supplied with demineralized water having a
specific resistance of 50,000 to 200,000 ohms/centimeter. The use of
unfiltered tap water or triple-distilled water will damage the humidity system
and chamber interior, and will void the warranty.
Plumbed Demineralized Water Installation
Follow these instructions if your chamber is NOT being used with the optional W100 Water
Recirculation System, and you are connecting to a plumbed source of demineralized water.
1.
Attach a supply of demineralized water to the Water Supply fitting on the rear of the
chamber. Water pressure must not exceed 50 psi.
2.
The chamber drain water is not under pressure, and is fed by gravity. Therefore, it must
empty into an open floor drain, condensate pump, or bucket.
Water Recirculation System Installation, Model W100
The optional Model W100 Water Recirculation System provides a source of demineralized water
for the humidity system, using ordinary tap water. Condensate from the chamber is returned back
to the water tank. The water pump runs continuously when the humidity system is enabled,
keeping the supply line pressurized at all times. Detailed assembly pictures are shown on the
next page.
1.
Attach filter cartridge. Use clamp provided on each end of filter to prevent leaking. Do not
overtighten.
2.
Position the recirculation system on the back left side of the chamber.
3.
Attach the chamber Water Supply hose from the chamber to the top fitting of the filter. Use
clamp provided to secure the hose to the Water Supply fitting.
4.
Attach the chamber Drain hose to the chamber and position it so it goes into the water tank.
The drain hose must not be submerged in the water.
5.
Fill the water tank with clean water.
6.
Place the cover on the water tank.
7.
Plug the pump power supply into the receptacle labeled Pump on the rear of the chamber.
Water Recirculation System Filter Cartridge Replacement
The demineralizer filter cartridge must be replaced when it is used up. The color of the bottom
half of the cartridge changes gradually brown through continued use. Replacement cartridges are
available from TestEquity (part number TE-0014 for a carton of 6 cartridges).
