Final assembly
Upper buffer chamber
1
Rinse both buffer chambers with water and distilled
water thoroughly before each use.
Clean away any gel adhering to the exterior of the
gel sandwiches.
2
If running only one gel:
Block the second upper buffer chamber slot by
installing the acrylic buffer dam included with the
unit. Fit clamps onto the dam, taking care to align the
clamp ends and dam edges. Install the “dummy” gel,
screws facing out, in the second cradle in the dual gel
caster.
3
Attach the gel sandwich to the upper buffer chamber.
Turn the upper buffer chamber upside down and place
a slotted gasket into both sandwich holder recesses.
Both the slot in the gasket and the slot in the recess
must align. Both slotted gaskets must be used even
if running only one gel sandwich. Grooves along each
slot help keep the gasket in place. Additionally, a
small amount of Gel Seal can be applied at each end
of the gasket before install to help hold the gasket
against the upper buffer chamber.
Release the sandwiches from the caster by removing
all bottom cams (if present). Lower the upper buffer
chamber onto the gel sandwiches in the casting
stand. Install the cams, ridge pointing down, into
the buffer chamber cam holes. Cam the sandwich in
place by simultaneously turning one cam clockwise
and the other counterclockwise a full 180°.
Note: Do not force the cams.
If encountering unusual resis-
tance, disassemble and inspect
clamp and glass alignment
along the top of the sandwich.
Align and reinstall.
Fig 6. Attaching gel sandwiches to
the upper buffer chamber.
If the assembly leaks, take it to a
sink and partially release the cams
to allow buffer to drain out of the
upper chamber. Disassemble, check
alignment of all sandwich compo-
nents, and adjust if necessary.
A. Remove cams from the lower
cam holes. Place the upper
chamber onto the sandwiches
and then insert the cams into
the upper cam holes, ridge
(short end) pointing down.
B. The final cam position (not
shown) must be vertical so that
the assembly fits into the lower
buffer chamber.
