5. Apply liberal beads of case joint sealant (butyl) to
the areas (solid dark lines) shown in the diagram
below (Fig.2, #1) of the first case.
do not USe PlUmber'S PUttY!
do not USe PlUmber'S PUttY!
Plumber's putty will not allow the cases to be fully drawn
together which will cause gaps between the cases resulting
in poor bodywork fit, finish and case sealing. Only use
Plumber's putty where necessary after the cases have
been bolted and drawn tightly together.
It is the contractor's responsibility to install
case(s) according to local construction and
health codes.
6. Slide the second case up to the first case snugly.
Then align the second case to the first case so that
the glass, front bumper, bodywork, and top are
flush.

7. To compress the sealant at the joints, use two
Jurgenson or similar hand screw type wood
®
clamps. Make sure the case is level from front to
back and side to side per the instructions in step 1. If
using clamps on the plastic sprayed interior liner use
scrap wood (as wide as possible) under the clamps
so that the liner is not damaged. Be careful to
observe the area where the clamp is being tightened
so that the case is not damaged as pressure is
applied.
8. Attach cases together via  bolts located in the end
leg tubes at the base of the cases and 1 bolt in the
rear raceway end brackets. On fixed glass Meat and
Fish cases, there are  additional bolts in the top of
the case that are accessible by removing the top
insert. The top insert is removed by pushing up on
the bottom side of the insert from inside of the case.
9. Remove the masking tape from the bulkheads only
and trial fit the stainless steel bulkhead caps. Once
proper fit is confirmed, apply a bead of silicone to
the tops of the bulkheads and install the stainless
steel bulkhead cap. Also, sparingly apply silicone to
seal case interior and exterior bodywork as needed
to ensure a water-tight seal, and a cleanable and
professional appearance. Use a finger in a clean
rag, as you go, to smooth the silicone as thin as
possible on the inside and outside of the case, while
it is still fluid. (Apply additional silicone if necessary).
Immediately remove the masking tape applied in
step 3.
GLASS BREAKAGE MAY OCCUR!
Retighten glass along glass clamp after
leveling and first time case is brought
to full operating temperature!
