REASSEMBLY OF AH4260

To reassemble the air handler, reverse steps above starting with number 7.


SETTING UP THE A-COIL FOR AIR CONDITIONING

The AH2436 & AH4260 come with the A-coil pre-installed for vertical and left to right horizontal
airflow. The A-coil can also be re-positioned for counterflow operation.

IMPORTANT: When air handler is installed in attic above a finished ceiling, it is recommended that a
safety overflow pan with its own separate drain be installed under the entire unit.


For a right to left horizontal air flow the following steps 1-7 must be followed.
Otherwise skip to step 8.

Reversing the horizontal orientation

1. Remove the front a-coil access panel of the air handler.
2. Remove the front a-coil drain pan retainer.
3. Remove the horizontal drain pan support shipping screw(s) from the right side casing.
4. Remove the A-coil assembly and slip the horizontal drain pan assembly off of the right side of the

A-coil.

5. Slip the horizontal drain pan assembly onto the left side of the A-coil.
6. Re-install the A-coil assembly into the air handler. The A-coil drain pan should slide under the rear

retention clip. The horizontal drain pan assembly should rest against the left side casing insulation
and the side support angle.

7. Re-install the front a-coil drain pan retainer in front of the a-coil drain pan.


For all orientations

8. Cut open the appropriate drain pan drain access hole in the front A-coil access panel.
9. Slip the Suction line grommet panel over the suction line up to the access panel surface.
