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.
