ICE CFA1012A I&O Manual 01/2021 New
Additional Items Needed:
Additional hardware and miscellaneous supplies (not furnished by ICE) are needed for installation.
For example, the list below contains approximate quantities of items typically needed for mounting a
unit on a concrete, fiberglass or steel frame structure. Concrete and fiberglass structures have different
requirements.
• Silicone Sealer
to seal around cracks and openings. Seal all top mounting holes not used and pro-
vide a seal at the top of the unit where it meets the building to eliminate water intrusion. Provide a
complete perimeter seal between the unit and cabinet. The insulation that is factory installed around
the supply and return air openings is an air seal only. It is not a water or weather seal.
• Use appropriate electrical supplies
such as
conduit, electrical boxes, fittings, wire connectors
, etc.
• High voltage wire
sized to handle the MCA (minimum circuit ampacity) listed on the data plate
and in the
Electrical Ratings
table in section 1.4.
• Over-Current Protection Device
sized in accordance with the MFS (maximum fuse size) listed
on the unit data plate and in the
Electrical Ratings
table in section 1.4.
WARNING FIRE HAZARD

Ducting
Extension length should be cut flush with the inside wall for applications without duct work.
Applications using duct work should be designed and installed in accordance with all applicable safety
codes and standards. ICE strongly recommends referring to the current editions of the National Fire
Protection Association Standards 90A and 90B before designing and installing duct work. The duct
