4. AIR DISTRIBUTION SYSTEM

SIZING & DESIGN

The Installer of this air conditioner/heat pump system must design the air distribution system for their particular application. Several

requirements for this system MUST be met for the air conditioner/heat pump to operate properly. These requirements are as

follows:

A. The duct material must meet or exceed any agency or RVIA Standard that may be in existence at the time the RV is produced.

B. All discharge air ducts must be properly insulated to prevent condensation from forming on their surfaces or adjacent surfaces

during operation of the air conditioner/heat pump. This insulation must be R-7 minimum.

C. Ducts and their joints must be sealed to prevent condensation from forming on adjacent surfaces during operation of the air

conditioner/heat pump.

D. Return air openings must have 40 square inches minimum free area including the filter.

E. Return air to the air conditioner/heat pump must be filtered to prevent dirt accumulation on air conditioner/heat pump cooling

surface.
