be accomplished without removal of any panels surrounding this upper
Bath Vessel Housing.
Cleaning heat sinks
If the bath is operating in a high humidity environment, dirt may become
very hard and encrusted on the fins of the heat sinks. If this condition is
noticed, it will be necessary to remove the left and right side panels to
gain access to the heat sinks.
Removing side panels/
accessing fluorescent lamps
To remove the side panel(s), first verify that the bath power cord has been
disconnected from the power supply. Remove the four screws which hold
the panel in place. Slide the detached side panel outward for a small
distance, then upward to avoid striking the fluorescent lamp.
Using a soft, long bristled brush (available in automotive departments for
cleaning wire wheels) loosen the encrusted dust and then blow it away
with the compressed air source. Care should be taken to not bend or
crush the fins of the heat sinks.
Reassemble the side panels back onto the Bath Vessel Housing by
reversing the removal procedure.
Compressed air cleaning
If a central or self-contained air compressor line with a blow gun is not
available, compressed air (aerosol) cans may be obtained from most
computer supply dealers. These cans may be used with a long nozzle to
help direct the air into a small area.
CAUTION
Eye protection should always be worn when using compressed air.
Cleaning the bath window
The viewing window on the TE-1500 is constructed with four panes of low
emissivity glass with all panes tempered for safety. The space between these
panes are filled with a gas and sealed to provide a frost-free viewing win-
dow. The outside (front) surface of this window may become smudged and
dirty and should be cleaned with common household window cleaner. Apply
window cleaner to a soft cloth and wipe on the front window of bath.
NOTE
Do not spray cleaner directly on front face of the glass.
Cleaning the inside of the bath vessel
To clean the inside of the bath vessel, empty the bath using the procedure
described on page 11 of this manual.
After all of the bath liquid has been removed and the bath vessel is at
room temperature, cleaning can begin. Use a long-handled brush and a
good quality liquid household cleaner. Spray the liquid cleaning agent
through one of the top holes in the bath vessel and use the brush to scrub
off residue on the baffle, side walls, and bath window. Rinse the vessel
with water and use a siphon or vacuum system to remove the remaining
mixture from the vessel. Ensure that the vessel is clean and dry before
refilling with clean alcohol. Use lint-free towels to wipe the vessel dry if
a vacuum system is not available.
