15 - VENT AND DRAINING OPTION - DOWNFLOW
Instructions for Downfl ow with Left Side Venting
1.
Remove 2.5” knockout and connect 2” nipple approximately
2.5” long (fi eld supplied) to the coupler on the exhauster.
Ensure exhauster coupler drain outlet is facing downward 15°.
2.
Connect 2” elbow and 2” vent pipe (fi eld supplied)
3.
Install gasket on panel then vent bracket, use three (3) self tapping
screws (all parts from parts bag). If using 1.5” or 3” vent, make
transition as close as possible to the unit and on a vertical section.
4.
Remove 2.5” knockout and connect 2” air intake coupler with gasket
on the outside of unit, use the 2” nut to fasten this (all parts from
parts bag).
5.
Connect 2” street elbow (from parts bag) and intake pipe (fi eld sup-
plied). If using 1.5” or 3” intake, make transition as close as
possible to the unit and on a vertical section.
6.
Remove two (2) 7/8” knockouts and install the condensate trap with
gasket, hold in place with two (2) screws (all parts supplied in parts
bag). **Condensate trap can be placed on either side of unit**
7.
**IMPORTANT** Connect a 1/2” tee fi tting (fi eld supplied) to the
outlet of the condensate trap.
8.
Connect 1/2” drain tube (fi eld supplied) and route to fl oor drain or
condensate pump.
9.
Connect one end of the 5/8” tubing (in parts bag) to the drain on
the front manifold cover, route to the larger outlet on the condensate
trap, cut excess tube and hold in place with supplied hose clamps.
Tubing should slope towards drain trap with no sags.
10.
Connect one end of the 1/2” tubing (in parts bag) to the lower drain
outlet on the exhauster coupler, route to the smaller inlet on the
condensate trap, cut excess tube and hold in place with supplied hose
clamps. Tubing should slope towards drain trap with no sags.
Instructions for Downfl ow with Right Side Venting
1.
Remove 2.5” knockout and connect 2” nipple approximately 7” long
(fi eld supplied) to the coupler on the exhauster. Ensure exhauster
coupler drain outlet is facing downward 15°.
