C − Outdoor Fan Motor
All units use single−phase PSC fan motors which require a run
capacitor. In all units, the condenser fan is controlled by
the compressor contactor.
ELECTRICAL DATA tables in this manual show specifi-
cations for condenser fans used in XP13’s.
Access to the condenser fan motor on all units is gained
by removing the four screws securing the fan assembly.
See figure 9. The grill fan assembly can be removed from
the cabinet as one piece. See figure 10. The condenser
fan motor is removed from the fan guard by removing the
four nuts found on top of the grill. See figure 10 if con-
denser fan motor replacement is necessary.
Make sure all power is disconnected before
beginning electrical service procedures.

D − Reversing Valve L1 and Solenoid
A refrigerant reversing valve with electromechanical so-
lenoid is used to reverse refrigerant flow during unit op-
eration. The reversing valve requires no maintenance. It
is not repairable. If the reversing valve has failed, it must
be replaced.
