11.2 FLOW PLATE CLEANING
The unit is designed for quick and easy cleaning. Remove the Blue Lamp Box and place on the
chamber door to access the flow plate. Wipe the flow plate with a clean damp cloth. The flow plate may
be removed for cleaning if desired. Do not use soap as this may cause an inaccurate reading if not
rinsed completely. One suggestion would be to use windex brand class cleaner with “anti-fog” to clean
the flow plate. For persistent stains use Muriatic acid (18%) or Isopropyl Alcohol. Replace the flow
plate. Verify an even water flow across the flow plate. Place the Blue Lamp Box back on the Tray and
secure it with the retaining latch. Close the door snugly.
11.3 LAMP
REPLACEMENT
Power off the unit. Allow 15 minutes for the lamp to cool. Open the chamber door. Open the Blue lamp
Box lid to view the lamp. See section 3.3 for moere detail information. The lamp is connected to a
socket and the unit is held down with the single knurled screw. Undo the screw and carefully lift the
lamp up. Remove the lamp from the socket (unscrew the connectors mounting block) and insert the
new lamp. (Note: the socket has a polarity to direct you). Secure the new lamp into place with the metal
band and knurled screw. Close the lid. A calibration must be performed after a 24 hour warmup of new
lamp.
