Step 8 — Position Power Exhaust/Barometric
Relief Damper Hood —
hoods folded inside the unit in a shipping position. For 50AJ
and AK units the hood must be tilted out once the unit is in-
stalled. On 50AW and AY units, (designed for horizontal sup-
ply and return) the assemblies will have to be relocated to re-
turn ductwork. See Fig. 36 for dimensions and details.
All electrical connections have been made and adjusted at
the factory. The power exhaust blowers and barometric relief
dampers are shipped assembled and tilted back into the unit for
shipping. Brackets and extra screws are shipped in shrink wrap
around the dampers. If ordered, each unit will have 4
(50AJ,AK,AW,AY020-050 units) or 6 (50AJ,AK,AW,AY060
units) power exhaust
(50AJ,AK,AW,AY020-050 units) or 6 (50AJ,AK,AW,AY060
units) barometric relief dampers.
