The 39M air handler (see Fig. 1) has a design that allows hundreds of different configuration possibilities. Each unit is assembled to meet specific job requirements and can be shipped in sections or as a single assembly. These instructions describe how to install, start up, and service 39M air handlers. Fig. 1 Typical 39M Air Handler Manufacturer reserves the right to discontinue, or change at any time, specifications or designs without notice and without incurring obligations.

2 SAFETY CONSIDERATIONS 39M air-handling equipment (see Fig. 1) is designed to provide safe and reliable service when operated within design specifications. To avoid injury to personnel and damage to equipment or property when operating this equipment, use good judgment and follow safe practices as outlined below. NEVER enter an enclosed fan cabinet or reach into a unit while the fan is running. LOCK OPEN AND TAG the fan motor power disconnect switch before working on a fan. Take fuses with you and note removal on tag. LOCK OPEN AND TAG the electric heat coil power disconnect switch before working on or near heaters. CHECK the assembly and component weights to be sure that the rigging equipment can handle them safely. Note also the centers of gravity and any specific rigging instructions. CHECK for adequate ventilation so that fumes will not migrate through ductwork to occupied spaces when welding or cutting inside air-handling unit cabinet or plenum. WHEN STEAM CLEANING COILS be sure that the area is clear of personnel. DO NOT remove access panel fasteners until fan is completely stopped. Pressure developed by a moving fan can cause excessive force against the panel and toward personnel. DO NOT work on dampers until their operators are disconnected. BE SURE that fans are properly grounded before working on them. SECURE fan drive sheave with a rope or strap before working on a fan to ensure that rotor cannot freewheel. DO NOT restore power to unit until all temporary walkways inside components have been removed. NEVER pressurize equipment in excess of specified test pressures. PROTECT adjacent flammable material when welding or flame cutting. Have a fire extinguisher at hand and ready for immediate use. PREVENT unauthorized entry into the unit; leave safety latches in place on access doors except during installation or service procedures. After accessing a section, replace and tighten the safety latch. FIELD SUPPLIED MOTORS should be Underwriters Laboratories (UL) or Canadian Standards Association (CSA) approved. FIELD WIRING must comply with National Electrical Code (NEC) and all local requirements. DO NOT ground equipment to fan assembly when welding. Damage to fan bearings could result. UNIT AND COMPONENT IDENTIFICATION The 39M comes in two basic configurations; horizontal and vertical. Using appropriate sections, it is possible to design many unit variations, including blow-thru units and plenum fan units with multiple discharges. Fig. 2A-2F show an example of the model number used for 39M unit sections and components. Each unit s model number is listed on a label affixed to the fan section. Section level part numbers are listed and affixed to each individual component section. For further information on unit and component identification refer to Table 1, Fig. 3A-3B and contact your Carrier representative for the AHU (Air-Handling Unit) Builder program. Refer to the 39M Product Data catalog for more information on individual component sections. 39M N Product Type 39M thru Standard Unit Code Model N Indoor Unit Unit Size Revision Level 39M (ULP) Fig. 2A 39M Unit Nomenclature 2

8 PRE-INSTALLATION Inspection Inspect the unit; file a claim with the shipping company if the unit is damaged. Check the packing list to ensure that the correct items have been received and notify your Carrier representative of any discrepancy. Rigging and Handling To transfer the unit from the shipping platform to the storage or installation site, refer to the rigging label on the unit and these instructions. (See Tables 2A- 15 for motor, component, and coil weights.) You can use a forklift truck to move units or components only if they have full skids. Lift from the heavy end of the skid. Minimum recommended fork length is 48 inches. Base units are shipped fully assembled, except when sections are separately ordered or when the unit height exceeds 108 in. or length exceeds 30 feet. All 39M units can be rigged using the lifting brackets, as shown in Fig. 4. Connection flanges are provided at specified sections to separate component sections: 1. Remove all fasteners on vertical and horizontal (side and top) seams. 2. Remove the large through-bolts in adjacent lifting brackets and smaller bolts that hold lifting brackets together. See Fig Lift the unit with slings and header bars, using clevises and pins in the large oval holes in the unit s lifting brackets. When the unit is in its final location, do not remove the caps from the coil connections until the coil is ready for piping. Do not remove grease from the fan shaft until the drive sheave is ready for installation. Do not stack unit components or accessories during storage. Stacking can cause deformation or damage.

34 Long-Term Storage If storing the unit before installation, observe the following precautions: 1. The storage site should be level, rigid, and free of debris. If the site is in a heavy rain area, set the unit off of the ground. 2. Do not store the unit in a heavy traffic area or on a vibrating surface.vibration can damage stationary bearings. 3. Ensure that all coil connections have shipping caps in place. Cover the entire unit with a waterproof tarpaulin or plastic coverall; if the unit is stored on the ground, extend the cover underneath the unit. Secure the cover with tiedowns. Do not remove cover or coil end caps until unit is ready for final installation. 4. Monthly- Move the coverall, enter the fan section through the access door or fan inlet, and slowly rotate the fan and motor by hand. This operation prevents bearing corrosion by redistributing the bearing grease. Service Clearance When planning the placement of the unit, ensure adequate space for service access. Typical service operations can require removing the coils and filters and accessing the motor and damper linkage. Refer to AHUBuilder program for recommended clearances. Drain Positioning To prevent build-up of condensate in the drain pan and ensure proper operation of the drain system, position the unit so that condensate is properly trapped. Refer to the Condensate Drain section on page 56 in the Installation section. Unit Suspension Unit suspension methods are shown in Fig. 5. A field-supplied platform mount is recommended, especially for larger unit sizes. An inline twin-beam mount is also recommended. Units can also be supported by attaching suspension rods to all of the lifting brackets on all of the unit sections that have more than 15 in. of airway length, or by suspending the unit from cross-beams at the joint between each unit component. Ensure that suspension rods are secured to adequately support the unit and that the rods extend entirely through their associated fasteners. Internal Vibration Isolation All units have internal vibration isolation and must be prepared as described in this section before they are installed. REMOVING HOLDDOWN BRACKETS, AIRFOIL AND FORWARD-CURVED FANS Remove the holddown brackets (Fig. 6) as follows: 1. Open the fan access door. 2. Remove the sheet metal screws that fasten the upper holddown bracket to the door frame and side panels. 3. Remove the sheet metal screws that fasten the base frame assembly to the upper holddown bracket, and discard the bracket. 4. On the same base frame member, remove the sheet metal screws in the base frame assembly. Remove and discard the lower bracket and wood shipping skid. 5. Repeat Steps 1-4 on the opposite side of the fan section. Fan sled assembly should float on isolator springs when done.

35 REMOVING BOLT, AIRFOIL, BACKWARD INCLINED AND FORWARD-CURVED FANS Remove the bolt (Fig. 7) as follows: 1. Open fan access door. 2. Locate the bolt. Loosen and remove the bolt. 3. Remove the bolt from the unit completely by rotating and sliding the bolt through the hole in the bottom of the fan section. 4. Repeat Steps 1-3 on the opposite corner, and twice on the opposite side of the fan section. Fan sled assembly should float on isolator springs when done. A total of 4 bolts must be removed. ADJUSTING ISOLATOR SPRINGS, AIRFOIL, BACK- WARD INCLINED AND FORWARD-CURVED FANS Units with factory-supplied motors and drives are preset to 13/ + 1 / 8 -in. clearance between the base frame assembly and the bottom panels; field adjustment of the isolator springs is not normally required. Units that receive field-supplied motors require isolator spring adjustment to 13 / -in. nominal clearance after the fan motor, sheaves, and belts have been installed.

Serious injury can result. Be sure to disconnect power and tag controls before making adjustments. When field-supplied motors and drives have been installed, adjust the isolator springs as shown in Fig. 6 and 7 and described as follows: 1. Loosen the locknut. 2. Turn the adjusting stem until the specified clearance of 13 / + 1 / 8 -in. is obtained. (Turn clockwise to decrease clearance or counterclockwise to increase clearance.) 3. Tighten the locknut. 4. Repeat for each of the isolator springs and ensure that the fan sled is floating on the springs. REMOVING HOLDDOWN BOLTS AND ADJUSTING ISOLATOR SPRINGS, PLENUM FANS Remove holddown bolts securing fan sled to bottom of unit. Plenum fans with factory-supplied motors should not require vibration isolator adjustment. For plenum fan with field-supplied motor, install motor and adjust internal isolators so that fan sled is level and does not touch bottom panels. External Vibration Isolation Install external vibration isolators per certified drawings, job specifications, and the instructions of the isolator manufacturer. The coil piping must also be isolated or have flexible connectors to avoid coil header damage due to motion or vibration. Flexible connections should also be installed at the fan inlet (if ducted) and at the discharge. INSTALLATION This section describes how to install 39M units, components, and component parts. Units specified on a single order are shipped with most components assembled in the specified airflow direction. The assembled unit is attached to a single shipping skid (30-ft. maximum length). When an upper component exceeds the 108-in. maximum height limit, it is shipped out of its operating position on the unit skid or on a separate skid. Some component parts also require assembly or adjustment; see the section on each component type for specific instructions. Unit/Section Connection Units are connected together using 2 different methods screws (factory connection) and T latch cam latches (field connection). Refer to Fig. 8 for T-latch assembly details. Connect units as follows: 1. Place the supplied 1 / 8 -in. thick x 1-in. wide gray foam gasket around perimeter of unit frame. NOTE: The gasket must not cover the attaching holes for the T latch opening (see Fig. 9 and 10). 2. Rig and align units so that sides and tops are flush and holes are aligned. 3. Fasten base rails together at the lifting brackets using supplied hardware. 4. Units secured with T latches: Turn T latch (indicated by red hex socket access) clockwise using an 8 mm hex wrench until latch fully engages. The latch rotates 270 degrees. The first 90 degrees of rotation positions the T-latch into a sealing position on the frame. The second 180 degree rotation pulls the T-latch tight, compressing the gasket which creates the frame seal. 35
