Overview
Horizontal units can be fi eld converted between side (straight)
and back (end) discharge using the instructions below.
Note: It is not possible to fi eld convert return air between
left or right return models due to the necessity of
refrigeration copper piping changes.
Preparation
It is best to fi eld convert the unit on the ground before hanging.
If the unit is already hung it should be taken down for the fi eld
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 fi eld 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 confi guration 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.
