3.0 APPLICATIONS
3.1 VERTICAL UPFLOW
▪ Vertical upow conguration is the factory set on all models (see g. 1).
▪ If return air is to be ducted, install duct ush with oor. Use reproof gaskets of 3.2 to 6.4 mm
(⅛ to ¼ inches) thick between the ducts, unit and oor. Set unit on the oor over the opening.
IMPORTANT : Torque applied to drain connections should not exceed 15 ft-lb (see g.1 and 2).
3.2 VERTICAL DOWNFLOW
Conversion from Vertical Upow to Vertical Downow : A vertical upow unit may be
converted to vertical downow. Remove the door and indoor coil and reinstall 180° from original
position (see g. 3).
IMPORTANT : To comply with certication agencies and the National Electric Code for
horizontal right application, the circuit breaker(s) on eld-installed electric heater kits must be
re-installed following the procedure below so that the breaker switch “ON” position and marking
is up, and “OFF” position and marking is down.
▪ To rotate breaker(s): Rotate one breaker set (circuit) at a time starting with the one on the
right. Loosen both lugs on the load side of the breaker. (Make sure that wires are identied
and are reinstalled into proper breaker). Wires are bundled with wire ties, one bundle going to
the right lug and one bundle going to the left lug.
