7. Overview / Silicone and Buty Application

Sealant Overview:

 Warranty is void if improper sealant is used.

 Sealing tub prevents air from escaping through seams

between cases (causing condensation problems and

reducing refrigeration efficiency).

 Sealing also prevents water from seeping between

cases to the floor.

Silicone and Butyl Application:

 Form (1) INNER sanitation bead AND (1) refrigeration

bead BEFORE case is adjoined (as shown).

 Then, AFTER case is adjoined (and bolted), form (1)

OUTER sanitation bead (as shown) into any cavities

or gaps that may remain along outer adjoinment areas

where butyl has ALREADY been applied.

 Also place a thick bead of caulk around drain.

8. Bolting Adjoined Units

 Bolt holes are at various locations (depending upon

model). Model illustrated MAY NOT exactly reflect

your particular unit but will likely be similar in layout.

 Use appropriately sized nuts and bolts for each hole.

 #1 hole is accessible at honeycomb (slight

adjustment or removal of honeycomb air diffuser

may be necessary for attachment of bolt).

 #2 hole is accessible near rear plenum.
