atwood Air Conditioners (13500, 15000) - Manual (Page 8)

ATTACH DUCT TO UNIT
- Raise the brace assembly and slip the
extension duct over the outside diameter of
the adapter underneath the rooftop unit. (Fig
11 & 12).
When attaching the duct to the unit take
care to ensure it forms a tight,
unbroken seal that doesn’t allow
discharge air to escape.
- Engage and tighten the four M8 bolts with
the threaded inserts in the rooftop unit.
- Recommended tightening torque of the bolts
is 7 N.m (5.2 lb-ft). As a rough guide the bolts
should be tightened so that the unit
compresses the roof seal gasket to
approximately half its height.
- As the bolts are tightened ensure that
the hold down bars slot into their recesses in
the brace (Fig 12).
ATTACH PLENUM COVER
- Connect the main cover of the plenum to the
duct by attaching the blue suspension cord to
the lug on the inside of the cover (Fig 13).
Reach into the unit, grab the control cable
plug and pull down to -This will allow you to
use two hands to connect the control cable
(see Fig 14).
- Connect the key pad control cables together
(see below). Be sure that the plug joins the
corresponding wire colors together (yellow to
yellow, red to red etc.)
Failure to properly plug the control
cables together correctly will result in
loss of power to display.
