Cleaning heat sinks
Removing side panels
Compressed air cleaning
Cleaning the bath window
NOTE
Draining the bath liquid
and the rear, and alternately apply blasts of air directly into the heat
sinks. This can be accomplished without removal of any panels surround-
ing this upper Bath Vessel Housing.
If the bath is operating in a high humidity environment, the dirt may
become very hard and encrusted on the fins of the heat sinks. When this
condition is noticed while attempting to blow out the dust, remove the
left and right side panels to gain access to the heat sinks.
Each side panel is attached with four screws and should be removed by
moving the detached side panel outward for a small distance and 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.
Assemble the side panels back onto the Bath Vessel Housing by reversing
the removal procedure.
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 in conjunction with a
long nozzle to facilitate directing most of the air into a confined area.
The viewing window on the TE-3000 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.
Do not spray cleaner directly
on front face of glass.
Remove all power from the TE-
3000 and remove all instru-
ments from the bath prior to the
draining operation.
The bath liquid in the TE-3000
must be removed by siphoning
action (see Figure 9). A general
purpose siphon is available
wherever kerosene heaters are
