INSTALLATION LIMITATIONS& RECOMMENDATIONS The general location of the air handler is normally selected by the architect, contractor and/or home owner for the most effective application and satisfaction. NOTE: Condensation may occur on the surface of the air handler when installed in an unconditioned location. When units are installed in unconditioned spaces, verify that all electrical and refrigerant line penetrations on the air handler are sealed completely. _i_ ....... Installer's These Guide air handlers are suitable for installation in a 6. It is recommended that the outline drawing be studied and dimensions properly noted and checked against selected installation site. By noting in advance which knockouts are to be used, proper clearance allowances can be made for installation and future service. 7. Allow a minimum of 21 inches clearance in front of the air handler to permit removal of COLLECTION CELL and FIELD CHARGER. 8. Do not install air handler where air cleaner can be exposed to UV light. 9. When the air handler with supplementary heater is to be installed in the downflow position on combustible flooring an accessory sub-base (TAYBASE101 for 2/4TEE3D31, TAYBASE100 for 2/4TEE3D37, TAYBASE102 for 2/4TEE3D40-65) must be used. See Figure 1. 10. If supplementary heat is to be added, power supply must be sut_cient to carry the load. In addition, minimum airflow settings, unit and duct clearances to combustible material must be maintained as closet, alcove or utility room with free, non-ducted, air return, using the area space as a return air plenum. With ducted supply air, if the minimum clearances to combustible materials and service access are observed, the above installations are suitable. This area may also be used for other purposes, including an electric hot water heater- but in no case shall a fossil fuel device be installed and!or operated in the same closet, alcove or utility room. In addition, these air handlers are suitable for installation in an attic, garage or crawl space with ducted supply and return air. This equipment has been evaluated in accordance with the U.S. Department of Housing and Urban Development code. Air handler is Suitable for mobile home/ manufactured housing use. Unit is also approved for modular homes. For proper installation the following items must be considered: 1. If adequate power is available and correct according to nameplate specifications. 2. Prior to unit installation, a heavy gauge steel plate is attached to the bottom of the unit for protection during shipping and handling. Leave this plate in place until the unit is ready to be connected to ductwork. 3. Insulate all ducts, particularly if unit is located outside of the conditioned space. 4. Pursuant to Florida Building Code 13-610.2.A.2.1, this unit meets the criteria for a factory sealed air handler. stated AIR HANDLER nameplate. [o lji o] NOTE: If air handler is used WITHOUT a supplementary electric heater, a sheetmetal plate is required to cover the open hole in the airflow system. See Figure 3. SUB-BASE ........

If the unit is installed without a return air duct, applicable local codes may limit this air handler to installation only in a single story residence & within conditioned space. 12. If the outdoor unit is to be installed later, or by others, then installation of the air handler must be made to allow access for refrigerant lines, or attach refrigerant lines to air handler when installing. 13. Make sure there are provisions for installing condensate drain lines. 14. If side, front or rear return is required, air handler must be elevated or placed on a plenum (TAYPLNM100 or 101). Connecting return duet directly to the side, front or rear of the cabinet is not approved. 18-GE10D1-4 15. Route refrigerant & condensate drain lines away from air handler so they do not interfere with access panels and COLLECTION CELL removal. 16. When external accessories are used, the additional height and width requirements must be considered in the overall space needed. 17. These units are not approved for outdoor installation. 18. These units are approved for draw-through application only. 19. DO NOT use silicon based sealant. This causes a coating on the FIELD CHARGER pins that will decrease the efficiency of the air cleaner. NOTE: No atomizing style humidifier is allowed in the return plenum with the use of this unit. 20. Flow-through Bypass Humidifiers Excessive bypass air may cause water blow-off, which will adversely affect system operation and air cleaner performance. To verify bypass airflow, follow the Bypass Humidifier Pre-Installation Cheekout and Set-Up Procedures available through your local distributor. Ask for publication number 18CH37D1-1. 3 Installer's Guide Steam and Flow-through Fan Power Ductmounted Humidifiers Follow the humidifier installation instructions. These should only be installed on the supply air side of the system. Other Duct Mounted Humidifiers are Not recommended for installation with the air cleaner. 21. Unit installation must include either a return air duet or grill that prevents accidental access to pins. For upflow open air intake applications that do not have a grill or return air duet, installation will require the use of either BAYPLNM120, TASB215, TA_qB235, or TA_qB260 depending on cabinet size.

Insulate the primary drain to prevent sweating where pipe temperature could meet or fall below dewpoint temperatures. Provide means for drainage to prevent winter freeze-up of condensate line. Do not connect the drain line to a closed drain system. Use Teflon _'_tape on the air handler drain line connections! Do Not Use pipe joint compound or PVC/ CPVC cement! It is always recommended that an auxiliary drain pan be installed under a horizontally installed air handler. Connect the auxiliary drain line to a separate drain line (no trap is needed in this line) and terminate according to National and Local codes. NOTE: DO NOT use a torch or flame near the plastic drain pan coupling. EZT-105 Figure 22 Field fabricated trap NOTE: DO NOT tighten the drain pipe excessively.

Field wiring diagrams for electric heaters and unit accessories are shipped with the accessory. Wiring must conform to National and Local codes. If an electric heater is not installed, the Knockout Plate provided in the Accessory Kit MUST be installed on the air handler and the conduit terminated to it. The electrical connections are made using the two power leads and ground wire connections which are located near the discharge of the blower. NOTE: If air handler is used with or without a heater, the electrical entry hole as well as any other cabinet penetrations must be sealed air-tight. I. CONTROL 1. Connect wiring between indoor unit, outdoor unit and Comfort Control. The use of color-coded lowvoltage wires is recommended. A low voltage terminal board is provided for control wiring, and is located on the left side of the cross brace in the center of the unit. 2. 3. WIRING Field wiring diagrams are provided on page 18 and 19 which show the low voltage wiring hookup for a single speed cooling only system (with supplementary heaters) and a heat pump system (with supplementary heaters). Plug in type electrical connectors are provided for use with supplementary heaters.

AIRFLOW ADJUSTMENT Disconnect power to the air handler before changing dip switch positions. Failure to follow this procedure may result in equipment damage. Blower speed changes are made on the ECM Fan Control mounted inside the control box. The ECM Fan Control controls the variable speed motor. There is a bank of 8 dip switches (See Figure 24). The dip switches work in pairs to match the airflow for the outdoor unit size (tons), cooling airflow adjustment, Fan off-delay options, and heating airflow adjustment. The switches appear as shown in Figure 25. If the airflow needs to be increased or decreased, see the Airflow Label on the air handler or the Blower Performance Table in the Service Facts. Information on changing the speed of the blower motor for your specific outdoor model size is in the Blower Performance Table. Be sure to set the airflow for the correct tonnage. Refer to blower housing for correct setting.

Chemicals used during the cleaning of the air handler or ductwork can damage the air cleaner components and degrade the performance of the air cleaner. PROCEDURE NOTE: In normal operation, the air cleaner makes a slight sound as the air passes through and is cleaned. In some applications, you may notice this sound coming from the return air vent(s). If desired, this sound level can be reduced with minimal impact on air cleaning efficiency by reducing the power setting of the FIELD CHARGER. The unit is shipped with the power set at 9.6KV (high). If sound is heard, reduce power level to 8.0KV (low) at the switch on the power supply. See Figure 27. 1.
