Fig. 63 – Priming Condensate Trap
2. Connect field-supplied 5/8-in. (16 mm) ID tube with attached
funnel to upper collector box drain connection.
3. Pour one quart (liter) of water into funnel/tube. Water should run
through collector box, overfill condensate trap, and flow into open
field drain.
4. Remove funnel; replace collector box drain plug.
5. Connect field-supplied 5/8-in. (16 mm) ID tube to middle collector
box drain port.

1. If any of the original equipment wire is replaced use wire rated f or 105ºC.
2. Use only copp er wire be tween the disconnect switch and the f urnace junction box (JB).
3. This wire must be connected to f urnace sheet metal f or con trol to prove flam e.
4. Symbols are elec trical representation onl y.
5. Solid lines inside PCB are printed c ircuit bo ard conduct ors and are not included in
legen d.
6. Replace only with a 3 amp fus e.
7. Inductor may be used with 3/4 hp and 1 hp ECM Blower motors. Review motor instructions
if replacing motor to see if Inductor is required.
8. Factory connected when L GPS is not use d.
9. Blower-off delay: gas heating selections are 90, 120, 150 or 180 seconds, cooli ng
or heat pump 90, 30 seconds o r 5 seconds .
10. Ignitio n-lockout will occ ur after four consecutive unsuccessful trials-for-ignitio n.
Control will aut o-reset aft er three ho urs.
11. Induc er (IDM) mot or contains int ernal aut o-reset th ermal ov erload switches (OL).
12. PL 13 and PL14 not available on all motors. Blower motor (BLWM) leads may be
hardwired at motor. Depending on motor type, 24V Common wire may be in either
CTRL (PL5) or Power (PL6) Connector
13. N connections are int erchangeable within the N connect or bloc k.
14. BLWM is locked - rotor overload protected by redundant elec tronic con trol c ircuit s.

WARNING
!
CARBON MONOXIDE POISONING HAZARD
Failure to follow these warnings could result in personal injury or
death.
Failure to use a properly configured trap or NOT water-priming trap
before operating furnace may allow positive pressure vent gases to
enter the structure through drain tube. Vent gases contain carbon
monoxide which is tasteless and odorless.
CAUTION
!
UNIT OPERATION HAZARD
Failure to follow this caution may result in intermittent unit operation
or performance satisfaction.
Condensate trap must be PRIMED or proper draining may not occur.
The condensate trap has two internal chambers which can ONLY be
primed by pouring water into the inducer drain side of condensate trap.
