OWNERā S GUIDE -Figure 6Secure foam topped, three-sided, telescoping divider plate (which is predetermined according to the mea-sured thickness of the ceiling cavity, refer to p. 10) to the divider plate by tightening two screws, referenceFigure 2 of page 11. The numbers located next to the mounting holes on the telescoping divider plate refer tothe ceiling cavity depth. Install the thin seal divider pad at this time. See Figure 7. Pad is provided with adhesiveon one side with release paper.Familiarize yourself with the high voltage wiring box, strain relief and wiring. The 115V supply wiring must berouted through the strain relief in the high voltage wiring box and secured to wiring inside. Extend the threehigh voltage wiring box leads and prepare them for attachment to the supply wiring.A low voltage terminal strip on the front of the box connects to the 12 VDC wires.After having prepared the roof top unit, place it over the roof opening.Position ceiling assembly frame into the ceiling opening. For proper orientation of the ceiling assembly frame,reference Figure 7.When inserting the ceiling assembly frame into the roof opening, be careful not to pull the foam insulation awayfrom the sides of the ceiling assembly. The insulation is required to create a positive air seal within the ceilingcavity.NOTE13A. Preparation12B. Mounting12CEILING ASSEMBLY FRAME PREPARATION AND MOUNTING
