3. Fill the bottle with silicone fluid and screw the Fill Cap Assembly
onto the bottle. Ensure that the breather tube is positioned with the
tube opening at the bottom of the bottle.
4. Insert the end of the fill tube from the Fill Cap Assembly into the slot
in the top of the bath flange.
5. Lift and invert the bottle to begin introducing 900 mL of the appro-
priate grade of ambient-temperature silicone bath fluid into the bath.
Add a small amount first and check for leaks. Then continue filling to
the cold fill level, marked by a decal cold fill line. The cold fill line is
approximately 3 centimeters (1.25”) below the bottom of the top bath
flange.
CAUTION
Do NOT overfill the miniAV-X bath, as the liquid level will rise with
temperature.
6. When done, lower and invert the bottle to stop the fluid flow, remove
the fill tube from the bath, and detach the Fill Cap Assembly. Store
the bottle and Fill Cap Assembly in a safe place for future use.
7. Replace the bath top cover. Check the bath for leaks to complete the
fill procedure. Tighten fittings if necessary.
NOTE
Periodically check the miniAV-X when the bath fluid is at ambient tem-
perature to ensure that liquid is being maintained at the specified cold fill
level.
Draining the bath
CAUTION
Remove MAINS power from the instrument before beginning the drain
procedure. Ensure that the bath has cooled to ambient temperature before
draining bath fluid. Hot silicone bath fluid can pose a hazard to laboratory
personnel.
1. Open the “ear” panels of the miniAV-X to access screws securing the
front bath cover.
2. Using a Phillips screwdriver, loosen and remove the four screws
securing the front panel to the Bath unit (see photo). Make certain to
hold the cover in place when removing the final screws. When the
screws have been removed, carefully remove the front cover and set
it aside.
3. Attach the drain hose of the appropriate ID to the stainless steel drain
tube adjacent to the viscometer tube tip (see photo). The other end of
the drain hose should be inserted in an appropriate bath fluid con-
tainer (or the supplied 900 mL bottle).
