ADJOINING CASES – MODEL FSIB8R SHOWN FOR ILLUSTRATIVE PURPOSES ONLY
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.
