NOTE: When converted to downflow position, the coil may protrude above the cabinet on some models.

Horizontal Conversion

Dedicated Downflow models are not suitable for horizontal application and must not be used for this type of installation. The only field modification required for conversion to “Hori- zontal Right-Hand” is the removal of the plastic knockouts in the horizontal panel drain connections. To prevent the hori- zontal drain pan from sweating in high humidity applications, it is recommended that a DPIH insulation accessory kit be used. NOTE: The DPIH insulation kit is not supplied with this product and should be purchased separately. See Table 8 for the correct DPIH kit.

The following describes converting to “Horizontal Left-Hand”.

Conversion to downflow MUST be performed in an area that allows access to all sides prior to placing the air handler in its

1.Remove the (3) air handler access panels.

2.Remove the “J” shaped bracket that retains the evapo- rator coil.

3.Remove the flowrator from the lower left side access panel and slide out the evaporator coil and horizontal drain pan.

4.Remove the gasket from the horizontal pan drain con- nections.

5.Remove the oval shaped plastic plug from the left side access panel. Remove the oval shaped rubber gasket seal from the lower right side access panel.

6.The drain connections for the horizontal pan are sealed with a thin coating of plastic. Carefully knock out this plastic seal with a screwdriver and hammer. Note: The upper drain will become the secondary drain which is mandatory in many municipalities .

7.Install the plastic plug removed in step 5 to the right side lower access panel and the oval shaped rubber gasket to the lower left access panel.

8.Reinstall the evaporator coil with the horizontal panel on the left side. Note: Push the assembly completely to the rear to ensure the engagement of the upflow pan with the rear channel bracket.

9.Install the “J” bracket (removed in step 2) to support the upflow pan to the tie channel.

10. Attach all panels and the metering device.

Condensate Removal

The coil drain pan has a primary and an optional secondary drain with 3/4" NPT female connections. The connectors re- quired can be 3/4" NPT male either PVC, CPVC or metal pipe and should be hand tightened to a torque of approxi- mately 37 in-lbs. to prevent damage to the drain pan connec- tion. An insertion depth between .355 to .485 inches (3-5 turns) should be expected at this torque. Use the female (3/4 fpt) threaded fitting that protrudes outside of the enclosure for external connections.

1.Ensure drain pan hole is NOT obstructed.

2.To prevent potential sweating and dripping on to finished space, it may be necessary to insulate the condensate
