Additional Items Needed:
Additional hardware and miscellaneous supplies (not furnished by ICE®) are needed for installation.
The list below contains approximate quantities of items typically needed for mounting a unit on a
wood frame wall structure. Concrete or fiberglass structures have different requirements. ICE cannot
recommend a specific method of attaching the air conditioner to the building due to the wide variety
of building types, code requirements, wall construction and specific installation conditions. The instal-
lation of the air conditioner to the building must take in to account all of these factors and follow best
industry practices to provide a safe and secure attachment to the building.

plus one inch (25 mm).
