Overview
Horizontal units can be field converted between side (straight)
and back (end) discharge using the instructions below.
Note: It is not possible to field convert return air between
left or right return models due to the necessity of
refrigeration copper piping changes.
Preparation
It is best to field convert the unit on the ground before hanging.
If the unit is already hung it should be taken down for the field
conversion.
Side to Back Discharge Conversion
1. Place unit in well lit area. Remove the screws as shown in
Figure 4 to free top panel and discharge panel.
2. Lift out the access panel and set aside. Lift and rotate
the discharge panel to the other position as shown, being
careful with the blower wiring.
3. Check blower wire routing and connections for tension or
contact with sheet metal edges. Reroute if necessary.
4. Check refrigerant tubing for contact with
other components.
5. Reinstall top panel and screws noting that the location for
some screws will have changed.
6. Manually spin the fan wheel to insure that the wheel is not
rubbing or obstructed.
7. Replace access panels.
Back to Side Discharge Conversion
If the discharge is changed from back to side, use above
instruction noting that illustrations will be reversed.
Left vs. Right Return
It is not possible to field convert return air between left or right
return models due to the necessity of refrigeration copper
piping changes. However, the conversion process of side to
back or back to side discharge for either right or left return
configuration is the same. In some cases, it may be possible
to rotate the entire unit 180 degrees if the return air connection
needs to be on the opposite side. Note that rotating the unit will
move the piping to the other end of the unit.
