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.

    6 – Holes are accessible at tabs just above air intake grilles.
