WARNING
!
ELECTRICAL OPERATION HAZARD
Failure to follow this warning could result in personal
injury or death.
For vertical supply and return units, tools or parts could
drop into ductwork, therefore, install a 90 degree turn in the
return ductwork between the unit and the conditioned space.
If a 90 degree elbow cannot be installed, then a grille of
sufficient strength and density should be installed to prevent
objects from falling into the conditioned space. Units with
electric heaters require 90 degree elbow in supply duct.
IMPORTANT: Use flexible connectors between ductwork and
unit to prevent transmission of vibration. Use suitable gaskets to
ensure weather tight and airtight seal. When electric heat is
installed, use fireproof canvas (or similar heat resistant material)
connector between ductwork and unit discharge connection. If
flexible duct is used, insert a sheet metal sleeve inside duct. Heat
resistant duct connector (or sheet metal sleeve) must extend 24- -in.
(610 mm) from electric heater element.
3. Size ductwork for max possible air flow (See Table 1).
4. Seal, insulate, and weatherproof all external ductwork. Seal,
insulate and cover with a vapor barrier all ductwork passing
through conditioned spaces. Follow latest Sheet Metal and
Air
Conditioning
Contractors
(SMACNA) and Air Conditioning Contractors Association
(ACCA) minimum installation standards for residential
heating and air conditioning systems.
