Product contains fiberglass wool.

Disturbing the insulation in this product during

installation, maintenance, or repair will expose you to

fiberglass wool. Breathing this may cause lung cancer.

(Fiberglass wool is known to the State of California to

cause cancer.)

Fiberglass wool may also cause respiratory, skin, and

eye irritation.

To reduce exposure to this substance or for further

GENERAL ton, 96W38 for the 2 and 2.5 ton, 97W95 for the 3 ton, and 97W96 for the 3.5 through 5 ton). All units may be installed with optional ECB25 field-installed electric heat and a matched outdoor unit. These air handlers are designed for indoor installation only. As shipped, the unit is ready for installation in either upflow or horizontal left-hand or right-hand air discharge applications. Downflow applications can be accomplished by purchasing the available downflow kit (96W37 for 1.

Install the conditioned air plenum, ducts and air filters (not provided) in accordance with NFPA 90B Standard for the Installation of Warm Air Heating and Air-Conditioning Systems (latest edition). Requirements WARNING Excessive Weight Hazard - Use two or more people when moving and installing the unit. Failure to do so can result in back or other type of injury. The air handler is shipped from the factory completely assembled. The unit is provided with flanges for the connection of the duct system.

Refrigerant Metering Device Installation Clearances NON-DUCTED RETURN CLOSET INSTALLATION The air handler can be installed in a closet with a false bottom to form a return air plenum. It may also be installed with a return air plenum under the air handler. Louvers or return air grilles are field supplied. Local codes may limit application of systems without a ducted return to single story buildings.

Right-Hand Air Discharge For horizontal right-hand air discharge, the following field modifications are require. Suspending Horizontal Unit 1. Remove and set aside blower and coil access covers. 2. Remove brachet(s) securing pan(s) to unit as illustrated in Figures 4 and 5. Remove Main Drain Pan Mounting Bracket (-018 through -036) Figure 2 NOTE: When the unit is installed in horizontal applications, a secondary drain pan is recommended. Refer to local codes.
PAGE 6
3. Remove coil assembly, bottom drain pan and horizontal drain pan as one assembly from the air handler. Install both Horizontal & Main Drain Pan Brackets 4. Move the horizontal drain pan to the opposite side of the coil. Be sure drain holes toward the back of the unit are plugged. Remove the plugs from the front drain pan ports. 5. Re-install modified coil/drain pan assembly in air handler in the same orientation as before (Figures 6 and 7).
PAGE 7
IMPORTANT On units of this type, where the blower “draws” rather than “blows” air through the coil, traps must be installed in the condensate drain lines (primary and auxiliary, if used). Traps prevent the blower from drawing air through the drain lines into the air supply. Typical Main and Overflow Drain overflow DRAIN LINE ABOVE FINISHED SPACE? ALWAYS RUN AN overflow DRAIN LINE. IF NOT POSSIBLE TO ROUTE overflow DRAIN LINE, INSTALL low voltage overflow SWITCH kit.

4. After removal of drain pan plugs, check the drain port to see if holes have been drilled. If not drilled, use a 19/32" bit to drill out the primary drain hole; use a 3/8" drill bit for the secondary drain hole. Remove all drill shavings. IMPORTANT A field-fabricated secondary drain pan, with a drain pipe to the outside of the building, is required in all installations over a finished living space or in any area that may be damaged by overflow from the main drain pan.

Supply and return duct system must be adequately sized to meet the system’s air requirements and static pressure capabilities. The duct system should be insulated with a minimum of 1" thick insulation with a vapor barrier in conditioned areas or 2" minimum in unconditioned areas. 1. Route the suction and liquid lines from the fittings on the indoor coil to the fittings on the outdoor unit. Run the lines in as direct a path as possible avoiding unnecessary turns and bends. 2.
PAGE 10
Make sure the liquid line and suction line entry points are sealed with either Armaflex material or with Permagum. Permagum may also be used to seal around the main and auxiliary drains and around open areas of electrical inlets. Electrical Connections WARNING USE COPPER CONDUCTORS ONLY! 1. Disconnect all power supplies. 2. Remove the air handler access panel. WARNING Electric shock hazard! - Disconnect all power supplies before servicing. 3.

Airflow - Cooling Blower Speed The cooling blower speed is factory configured to provide correct airflow for an outdoor unit that matches the maximum cooling capacity rating of the air handler. If the outdoor unit is smaller than the maximum cooling capacity rating for the air handler, the cooling blower speed may need to be changed. Refer to blower performance chart, Table 2.

barrier is damaged (wet, ripped, torn or separated from the cabinet walls), the surrounding ambient air will affect the inside surface temperature of the cabinet. The temperature/humidity difference between the inside and outside of the cabinet can cause condensation on the inside or outside of the cabinet which leads to sheet metal corrosion and subsequently, component failure. Maintenance IMPORTANT Do not operate system without a filter.
