Positioning The Unit In Horizontal Applications: Xah Coils; Repositioning The Transition Angle For Downflow Or Horizontal Right Application With A Furnace: Xaf And Xah Coils; Horizontal Right And Left Applications: Xah Coils - Johnson Controls XAF Series Installation Manual

Positioning the unit in horizontal
applications: XAH coils
• Set the unit so it is sloped 1/4 in. toward the drain
plug.
Repositioning the transition angle for
downflow or horizontal right application
with a furnace: XAF and XAH coils
About this task:
The coil cabinet has a factory installed transition angle
on the bottom front side of the cabinet. For downflow
or horizontal right applications with a furnace, you must
reposition this angle to the top front side of the cabinet.
Note: For installation with a modular air handling
unit, remove the transition angle and discard it.
1. Remove the two screws that fasten the transition
angle to the bottom front side of the cabinet.
2. Remove the two screws from the top front side of
the cabinet.
3. Remove the transition angle, rotate the transition
angle 180° end for end, and secure the transition
angle to the top front side of the cabinet.
Horizontal right and left applications:
XAH coils
See the following figures for an illustration of horizontal
right and left applications of XAH coils with furnaces and
modular air handlers.
