Kit Components
The mounting brackets overlap and are
fastened to the unit at existing holes.
Thread item 7 onto the discharge pipe at the
back of the unit. Do not over tighten.
Place the two mounting brackets together
and fasten them to the unit just below
the condensate discharge hose using
the 2 screws as shown.
Assemble items 1 thru 6 to make
the condensate trap sub-assembly.
There will be a remaining hose clamp.
Place it over the inlet hose and leave it loose.
With the 3rd hose clamp on the inlet hose, press the inlet side of the condensate trap assembly onto the PVC
adapter. The condensate trap will t into the bracket as shown below. Tighten the third hose clamp su ciently. Re-
check all hose clamps.
Use the velcro strap to fasten the condensate trap into the bracket assembly as shown below.
Run the Molex connector of the condensate trap sensor into the closest wiring grommet as shown. Reach into the
access panel and nd the Molex connector on the inside (blue and blue/white wire) and connect them.
Attach the condensate disposal system of your choice to the 'end adapter'. Check for condensate leakage when
the unit is running.
