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

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.

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.
