6.3 Vestibule (Doghouse) Assembly
Some ClimateCraft air handling units accept a bolt-on
vestibule (doghouse) for field attachment.
1. Using double-sided tape, affix two layers of
PGSK-001-001 to the base frame of vestibule
as shown in Figure 6-9.
2. Affix a single layer of PGSK-001-001 to the roof
panel flange of vestibule (Figure 6-10).
3. Affix, using double-sided tape, gasket PGSK-
005-003 to the wall panel flanges of the
vestibule (Figure 6-11).
4. Align vestibule so the holes in the vestibule wall
and roof panels align with the holes in the air
handling unit and draw together (Figure 6-12
and 6-13).
