Figure 18 22 Duct Connections All VariTrane units should be provided with a minimum of 1 5 duct diameters of straight duct prior to the inlet of the unit It is recommended that at least 48 inches of straight duct be provided from the discharge of the units prior to any take offs or transitions Important This is a requirement for electric heat fan powered units used in applications with 100 downward discharge Note In order to maintain good air distribution over the elements and not create turbulence which could cause a limit cutout there should be four feet of ductwork consistent of the discharge dimensions of the heater downstream of the reheat coil priorto any diffuser takeoffs for VariTrane electric coils 1 After all connections are made check that the entire ductwork system is airtight In some high pressure systems duct sealer may be necessary Note inlet duct on the boxes are sized approximately 1 8 smaller in diameter than the nominal size in order to allow the incoming duct to slide over the inlet of the VAV box 2 Provide insulation around the entire inlet collar all the way to the unit casing 13 TRANE Unit Installation Note Use caution not to damage the flow tubes when making ductwork connections or insulating 3 Cut slits in the insulation for the flow tubes and secure with duct tape 4 Ifthe unit is to be installed in a location with high humidity extern
