Refilling water bottle
The water bottle in the instrument typically needs to be filled about once a
month if the instrument is used on a regular basis in the Low Vacuum mode.
The water reservoir is located on the left side of the microscope console,
behind the cover. To fill the bottle, do the following:
1.
Run the
154 - Water Bottle Venting
alignment procedure
(see Chapter 4).
C a u t i o n !
Be aware of the gas type connected to the gas inlet before the Vent water bottle
button is clicked! If you are not sure, disconnect the gas pipes from the gas inlet
coupling.
2.
Open the Water bottle chamber cover.
3.
Pull out the water bottle and remove the threaded cap.
4.
Refill the bottle with distilled water (not de-ionized) until 1/3 full.

5.
Mount the cap and install the water bottle in the reverse order of that described above.
6.
Pump the chamber. Switch to LoVac mode to force automatic purging to flush any air out of the bottle and
connecting tubes.
Note
The first time the system is pumped to LoVac mode after filling the bottle, Auto-purging may be erratic until the bottle
pressure has steadied. The removal of all the gas from the liquid must be accomplished before good imaging is possible.
This has been done correctly when no bubbles are produced in the water when increasing the pressure in the chamber.
