Adjoinment - Urethane/Silicone Application
>> Warranty is void if improper urethane/sealant is used.
>> Lay generous beads of urethane/sealant as specified.
A. Prior To Adjoinment - Apply Industrial Grade
Urethane at Center of Uprights
• Apply a generous bead (approximately ø3/8”) of
industrial grade urethane at center of uprights
(not-visible to the naked eye).
• Proper urethane application prevents refrigerated air
from escaping between cases (causing condensation
and reducing refrigeration efficiency) as well as
preventing insects from entering case.
• See illustration below.
B. Adjoining Cases - Using Nuts, Bolts and Washers
• Use appropriately sized nuts, bolts and washers for
each hole.
#1 - Holes are accessible by removing honeycomb air
diffuser.
#2 - Holes are accessible at tabs just below honeycomb
air diffuser.
#3 - Holes are accessible at underside of decking. Deck-
ing must be removed to attach bolts/nuts.
#4 - Holes are accessible at tabs just below air intake
grilles.
#5 - Holes are accessible by reaching into opening just
below air intake grilles.
#6 - Holes are accessible at tabs just above air
intake grilles.
• Tighten nuts securely (be careful to NOT
over-tighten)!
• See illustration below.
C. After Adjoinment - Apply Food Grade
Silicone Sealant To Inner Seams
• After all nuts, bolts and washers are
securely attached to case, apply a
generous bead of food grade silicone
sealant to inner seams.
• Decking must be removed to apply sealant
to certain inner seam areas.
• 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.
