CASE ADJOINMENT: URETHANE AND SILICONE APPLICATION / BOLTING ADJOINED UNITS
Case Adjoinment
>> Warranty is void if improper urethane/sealant is used
in this process.
>> Lay generous beads of caulk/sealant as specified.
A. Prior To Adjoinment
-
Apply Industrial Grade
Urethane Adhesive (As Shown In Below Illustration)
•
Lay a generous bead of industrial grade urethane
adhesive in non
-
visible areas (as illustrated below).
•
This urethane adhesive prevents refrigerated air
from escaping between cases (causing
condensation and reducing refrigeration efficiency)
as well as preventing insects from entering the case.
•
See industrial grade urethane adhesive illustration
below

B. Adjoining Cases
-
Using Bolts and Nuts
•
Use appropriately sized nuts and bolts for each hole.
#1
-
Hole is accessible at underside of top surface
support.
#2
-
Holes are accessible through rear plenum and
behind honeycomb air diffuser.
#3
-
Holes are accessible at underside of decking.
Decking must be removed to attach bolts/nuts.
#4
-
Holes are accessible at base frame (through front of
case after front toe
-
kicks have been removed).
•
Tighten nuts securely (but do not over
-
tighten).
•
See accompanying illustration below.
C. After Adjoinment
-
Apply Food Grade Silicone Sealant
To Inner And Outer Seams
•
After all nuts/bolts are securely attached to case, apply a
generous bead of food grade silicone sealant at both
inner and outer adjoinment seams.
•
When properly applied, this food grade silicone sealant
will prevent water from seeping between cases (into the
case or to the floor) as well as crumbs or other residue
from entering between case seams.
•
See silicone sealant illustration below

>> You must reattach toe
-
kick and decking after case
adjoinment process is complete.
