3-8. Ducting. In many installations it will be necessary to duct the discharge air from the

Model 6715D to the exterior of the building. In some installations it will also be necessary

to supply inlet air from outside of the climate-controlled portion of the building.

The discharge air flow is approximately 325 SCFM at a maximum temperature of 250°F.

Due to the high temperatures involved, non-metallic duct materials should not be used for

the discharge duct, but may be suitable for inlet duct. Attaching a discharge duct to the

unit is easily accomplished:

Remove the 10 torx head screws attaching the discharge grill.

Then, replace the discharge grill with a discharge air duct adapter.

Suitable ducting can then be attached to the adapter. This duct should be as short as possible to

minimize back pressure. Design of the ducting and wall or ceiling penetrations should be

referred to a competent heating and air conditioning firm.

"Make-up air" is a ventilation term used to indicate the supply of outdoor replacement air

to a building in a controlled manner. It may be provided for the Model 6715D by ducting

into the room or by extending a supply duct to either intake grill of the blower enclosure

and installing a blanking plate on the other grill.

Make-up air will enter the building to equal the volume actually exhausted, whether or not

provision is made for this replacement. However, the actual exhausted volume may not

equal the design volume unless an adequate supply is provided.

3-9. Adjustments. No field adjustments are necessary or possible.

Preparation for Reshipment. No special measures are required to prepare the Model

-10.

6715D for reshipment. Care must be taken to protect the RF connector and to immobilize

the swivel flange. Packaging should provide protection against abrasion and impact.
