To prevent the evaporator coil pan from “sweating” the DPI accessory insulation kit is to be used when performing this conversion. Note: The DPI kit is not supplied with this product and is to be purchased separately. See Table 8 for the correct DPI kit. ARUFor ARPT model AEPT model Insulation Kit 018-032 n/a DPI18-30/20 036-042 30 DPI36-42/20 048-061 036, 060 DPI48-61/20 Table 8 Refer to Figures 5 through 7 for the location of the components referenced in the following steps. Figure 5 illustrates the new installation location for the removed components. 1. Before inverting the air handler, remove all access panels, the coil rear channel bracket, and the filter close-off panel. 2. Remove the evaporator coil and the horizontal drain pan. Discard horizontal drain pan. 3. Install the provided plastic plug into the vacated access panel. 4. Remove the two (2) zee coil support brackets and insulation retaining brackets. 5. Remove the tie bracket. 6. Install the DPI Insulation Kit onto the bottom of the drain pan. Return Air Side of Unit Rear Channel Bracket Zee Coil Support Bracket Access Panel Coil Retaining Bracket NOTE: The filter provision is not applicable in THIS downflow application. Tie Bracket Figure 5 7. Install the zee coil supports and the wrapper stiffeners. 8. Install the tie bracket. 9. Install the rear channel bracket. 10. To prevent possible condensate “blow off” the insulation retainers are to be laid into the evaporator coil pan as shown in Figure 6. 3" Flat Insulation Retainer (Both Sides) Figure 6 To complete the conversion, slide the evaporator coil into the chassis and attach the three (3) access panels. (Figure 7). CONVERSION TO HORIZONTAL The “B” series product is not suitable for horizontal application and must not be used for this type of installation. The following describes converting to “Horizontal Left- Hand”. The only field modification required for conversion to “Horizontal Right-Hand” is the removal of the plastic knockouts in the horizontal panel drain connections. MOTOR BLOWER TOP OF WRAPPER INSULATION JACKET ZEE COIL SUPPORT WRAPPER STIFFENER DRAIN PAN INSULATION DPI KIT (HATCHED AREA) NEOPRENE GASKET Figure 7 As shown in Figure 8, it is recommended that the conversion to horizontal be performed before placing the air handler in its final location and in an area that allows for access to all sides. 1. Remove the (3) air handler access panels. 2. Remove the “J” shaped bracket that retains the evaporator coil. 3. Remove the flowrater (or TXV) 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 connections. 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 refrigerant management device. Secondary Drain Primary Drain Figure 8 CONDENSATE REMOVAL The drain pan has a primary and secondary drain connection (Figure 8). Condensate removal is performed by attaching a .” PVC pipe to the evaporator coil pan and terminated in accordance with local or state Plumbing/ HVAC codes. The installation must include a “P” style trap that is located as close as is practical to the evaporator coil. Exercise caution not to over-tighten the drain connection(s) in order to prevent possible damage to the evaporator drain pan. See Figure 9 for details of a typical condensate line “P” trap. Installations that are above a finished ceiling may require a field supplied auxiliary drain pan. Consult local codes on this requirement. DRAIN CONNECTION 3" MINIMUM UNIT FLEXIBLE TUBING (HOSE OR PIPE) POSITIVE LIQUID SEAL (REQ'D) Figure 9 Use of a condensate removal pump is permitted when necessary. This condensate pump should have provisions for shutting off the control voltage should a blocked drain occur. A trap must be installed between the unit and the condensate pump. IO-230F 08/04 9 IMPORTANT NOTE: THE EVAPORATOR COIL IS COATED WITH OILS THAT MAY DISSOLVE STYROFOAM AND CERTAIN TYPES OF PLASTICS. THEREFORE, A REMOVAL PUMP OR FLOAT SWITCH MUST NOT CONTAIN ANY OF THESE MATERIALS. Tip: Priming the “P” trap may avoid improper draining at the initial installation and at the beginning of the cooling season. ...
