area where environmental conditions are controlled and
maintained so that the ambient temperature does not
exceed 75 °F (24 °C) and 55% maximum humidity.
 Type II display refrigerators are intended for use in an
area where environmental conditions are controlled and
maintained so that the ambient temperature does not
exceed 80 °F (27 °C) and 55% maximum humidity.
 If unsure if your unit is Type I or II, see tag next to
serial label. See SERIAL LABEL LOCATION &
INFORMATION LISTED / TECH INFO & SERVICE
section in this manual for sample serial labels.

 #2 hole is accessible near rear plenum.
 #3, 4 & 9 holes are accessible after removing decking.
 #5-6 holes are accessible after removing front panel.
 #7-8 holes are accessible after removing rear panel.
>> Be sure to reattach components to case after the
adjoinment process is complete.
5. Overview / Silicone and Butyl 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.
6. 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).
