1 ACCESSORY KIT INSTALLATION INSTRUCTIONS ELECTRIC HEAT ACCESSORY MODELS 2TP THROUGH 2358 FOR USE IN 3-5 TON PACKAGE PRODUCT (60Hz) UAI-A-0310 INSTALLATION Improper installation, adjustment, service or maintenance can cause injury or property damage. Therefore, only a qualified installer or qualified service personnel should perform this conversion. Table 1: Minimum CFM Limitations FOR SINGLE PACKAGE AIR CONDITIONERS MODELS: ZH, J**ZH, ZU, ZJ, J**ZJ AND ZW 3 THROUGH 5 TONS GENERAL This instruction contains all the necessary information for field installing the electric heaters listed in Table 1 in the single package air conditioners listed above. Terminal blocks, electrical connectors, wiring, and all hardware are supplied with these accessories. The data in Table 1 shows the heater kw/minimum CFM limitations. Tables 2 through 10 lists the heater combinations applicable to the appropriate size unit. Tables 3 through 12 also contain important electrical characteristics and limitations. Units and ductwork are approved for zero clearance to combustible materials when equipped with these electric heaters. NOTE: These heater accessories may be installed before or after the unit has been set on a curb or slab.

Open the following doors to the unit: a. Electric Heat Section b. Section c. Compressor Section d. Wiring Section 3. Remove the patch plate in the electric heat section and discard. NOTE: Retain the screws for use in installing the electric heater. Johnson Controls Unitary Products

2 4. Insert heater into space vacated by the patch plate. Slide into place tilting the rear of the heater up to allow the heater coils to clear the top flange of the heater compartment (see Figure 1). 6. Remove the knockout at the lower left corner of the blower section (see Figure 3). Heater assembly must be tilted back during installation to prevent damage to heater coils. KNOCKOUT LOCATION Figure 3: Knockout Locations 7. Install strain relief bushings in the knockout located in the lower left corner of the blower section, as shown in Figure 4. Figure 1: Heater Tilted Up In Rear 5. Once the heater is slid into place, it must be secured with screws removed from patch plate (see Figure 2).

3 8. Run wiring up through the strain relief bushings between the heater and blower compartments and slide protective tubing over wires where they pass through strain relief (see Figure 5). Figure 7: Heater Wire Raceway Filter Section Figure 5: Protective Tubing In Place NOTE: The tubing is meant to protect the wiring from damage due to clamping in the strain relief bushing. 10. Pull enough length of wire to reach under the control panel to the Terminal Block 1 from the compressor compartment. 11. Connect wires to the electric heater as shown in Figure Run electric heater wires through wire raceway to reach the control panel (see Figures 6 and 7). Figure 8: Wiring To Heater Assembly Figure 6: Heater Wire Raceway Section 12. Connect the control wiring harness from the electric heater to the control wiring plug found in the electric heat compartment. The plug and wiring will be found in the top left corner of the electric heat compartment, next to the knockouts. Johnson Controls Unitary Products 3

4 13. Tighten the strain relief bushing, clamping the protective tubing around the electrical wires (see Figure 5). 14. Secure the wires in the compressor section to the suction line. This is to keep the wires from interfering with the passage of the filters. 16. Pull electric heat wires under the control panel to the Terminal Block 1 and connect to the vacant lugs as shown in Figure 11. NOTE: WIRES ATTACHED TO TOP OF TERMINAL BLOCK 1. BLACK BLUE RED Figure 9: Heater Wires Secured to Suction Line 15. Apply silicon sealant in and around the strain relief connectors to thoroughly seal the holes between the blower compartment and the electric heat compartment (see Figure 10). Figure 11: Heater Wires Installed In Terminal Block Close all unit doors and secure. 18. Reconnect the power to the unit.
