Instructions / Assembly

The wall sleeve must be installed before the air conditioner or heat pump chassis can be set in

place. Read the instructions thoroughly before proceeding.

When 230/208 volt PTAC units are to be installed,

permanent wiring. Permanent wiring may be done

through the hardwire junction box, or the accessory

subbase.

wiring may be done through the accessory hardwire

junction box, or the accessory subbase. An exposed

may be installed.

The installer must determine and supply the mounting bolts and/or screws to attach the wall sleeve to the

wall opening.

The installer must provide adequate sealing and insulation around the sleeve after installation.

use extension cords.

If the wall is deeper than 13 7/8”, see your Sales Representative for correct installation.

There should be nothing within 20” of the back that would interfere with heat radiation and exhaust air

flow.
