For left side or right side mounted condensate trap, the pres-
sure tap on the condensate trap MUST be connected to the un-
used pressure tap located on the upper right hand corner of the
plastic transition box. Remove the plastic caps from the pressure
taps on the condensate trap and the plastic transition and connect
with the 5/16" OD rubber hose. (See Figure 13 and Figure 14)
Connect the 5/8" OD rubber hose with the 90 ° bend to the lower
drain stub on the vent fitting and secure with a 5/8" clamp.
Route the hose to the smaller drain stub on the condensate trap.
Cut off excess hose and discard. Connect the hose to the drain
stub on the trap and secure with a 5/8" clamp.
NOTE: Route hoses to the condensate trap with no kinking or
binding for proper condensate drainage.
