FIGURE 19: NSF Compliance Sealing (Silicone)
THIS PROCEDURE MUST BE FOLLOWED FOR NSF COMPLIANCE.
SURFACES TO BE SEALED MUST BE CLEAN, DRY, FREE OF BUTYL CAULK, AND FREE OF FROST (ABOVE 40ºF).
Note: Cases must be properly caulked and joined before NSF sealing. Wipe away any Butyl caulk that squeezes out of the case joint.
Butyl caulk and silicone sealant will not mix, which affects the adhesion of both.
1. Apply silicone-based sealant in small, continuous beads where indicated by the dotted lines in the drawing. Do not thin or feather, as that
will affect adhesion.
2. Sealant must be added between cases at case joints, between a case and an end panel, and between all access holes and cut-outs in the
case end frame.
