General Installation Information cont.
Bottomflow Application
To convert the SAH Series air handler for bottomflow ap-
plications follow the steps below:
1. With the air handler in the verticle top flow position
remove all access panels and the refrigerant line panel.
2. Carefully slide the air coil assembly out of the cabinet.
3. Rotate the cabinet 180˚ so the blower outlet is facing
down.
4. Install the SAHBCK bottom flow conversaion kit per
instructions in the kit. Failure to install this kit will
result in condensate blow-off from the 'A' coil into the
cabinet and ductwork.
5. Place the air coil assembly back on the air coil support
brackets.
6. Reattach the refrigerant line panel and the other access
panels.
7. Bottom air discharge units should be sealed well to the
floor to prevent air leakage.
NOTE: Air Handlers with control option 'C', which are
installed in the bottomflow or horizontal left position, will
have to re-route the condensate sensor and FP2 sensor
wires. The wires can be routed as shown below. A section of
electrical spiral wrap is included in the Installers Kit. Wrap
the section of wire that is placed in the corner with the
wrap to protect the wires.

Horizontal Left Air Discharge Application
To convert the SAH Series air handler for horizontal left air
discharge applications follow the steps below:
1. With the air handler in the vertical top flow position
remove all access panels and the refrigerant line panel
2. Carefully slide the air coil assembly out of the cabinet.
3. Remove and reposition the condensate deflector from
the vertical pan to the horizontal pan.
4. Rotate the cabinet 180˚ so the blower outlet is facing
down.
5. Place the air coil assembly back on the air coil support
brackets.
6. Reattach the refrigerant line panel and the other access
panels.
7. Position the air handler in the left hand horizontal ap-
plication.
8. Remove the drain pan plugs from the horizontal pan
and screw them in the vertical drain pan.
9. Reattach the refrigerant line panel and the other access
panels.
10. If the unit is suspended, the entire length of the cabinet
should be supported.
Important: When removing the coil, there is possible dan-
ger of equipment damage and personal injury. Be careful
when removing the coil assembly from the unit.
