1 - 09BB012 Air-Cooled Condenser . Receiving the Unit - Inspect unit for shipping damage. Enter any claims directly with the transportation company. Carrier Air Conditioning Company will not be responsible for damage incurred in transit. Uncrating - Remove unit and hardware from shipping skid. Check to see that unit and component parts conform to the bill of lading. Contents of fastener package are listed in Table 1. Before Installation - Check space requirements, service clearances, floor strength, location of piping, size of power supply, and location of ductwork (Fig. 2 and Fig. 3). Make sure rigging equipment is adequate, Avoid undue force against side and front panels when lifting unit.

These brackets have been designed to provide adjustable heights for the 09BB to the nearest 1/2 in. This is done by providing two sets of mounting holes on the bracket, spaced 1-1/2 in. apart. The upper mounting holes allow 09BB unit height adjustment in 1-in. increments starting 1 ft 10-1/2 in. from the floor. The lower mounting holes allow height adjustment in 1-ir. increments starting 2 ft from the floor. Install brackets as follows: 1. Remove the top four retaining screws on each side of the back panel of 50BB. 2. Select mounting holes and place bracket in position. Install with retaining screws and channel bolts in shipping holes (Fig. 4). 3. Install support bolts as shown in Fig. 3. 4. Install vibration isolators (supplied) in lowest hole each side of 50BB back panel (Fig. 4). Remove Tinnerman nut and install each vibration isolator with 5/16 in. plain washer (supplied in fastener package). Fig. 4 - Installation of Mounting Brackets Positioning 09BB Unit - For typical installation refer to Fig. 3. WARNING: The 50EB unit will not balance the 09BB unit without additional support. Once 09BB unit has been positioned in the mounting brackets, install locking bolts as shown in mounting bracket detail. Before sliding units into final position, check for clearance to access panels, and service area to install piping. Vertical Discharge - 09BB unit can be mounted as shown in Fig. 5. It will be necessary to relocate the electrical junction box either external to unit (as shown) or on an interior panel. Also, provide a rain drain on back of unit. PIPING 09BB hot gas and liquid line piping is factory supplied when field mounting the 09BB to the 50BB. The preformed piping is arranged for various mounting heights. Cut the vertical rise of tubes for height adjustment. No bending is required. 09BB units are factory charged with refrigerant. Liquid and hot gas lines are installed as follows: Compatible Fittings - Liquid and hot gas lines are installed from the 50BB unit to the 09BB unit with Carrier compatible fittings and service valves. These fittings may be used as sweat or mechanical connections. Install either type as follows: MECHANICAL CONNECTIONS 1. Cut tubing to length and remove burrs. Be careful not to expand tubing. 2. Remove plug from fitting and loosen nut one turn. 3. Position tube. Remove cap and insert tube in fitting to depth indicated on tag (1-1/4” depth for 5/8" and 3/4” tube, 3/4” depth for 3/8” and 5/16” tube). 4. Leave nut loose at condenser end of each tube. Purge one line at a time using 50BB base unit holding charge. 5. Tighten nut to a stop on unit fitting collar. 6. Open all service valves. 3 SWEAT CONNECTIONS 1. Cut tubing to length and remove burrs. Be careful not to expand tubing. 2. Clean tubing. Remove plug and nut from fitting. 3. IMPORTANT - Remove O ring from inside fitting. Wrap entire valve with wet rag. 4. Insert tubing in fitting and solder with low-temperature solder (450 F) such as Allstate 430. NOTE: Make solder connection at 50BB unit, then connect to 09BB unit except for soldering. Purge with 5GBB holding charge, then solder. Brackets - After installing piping from 50BB to 09BB units, install the following: HOT GAS LINE BRACKET - Install proper size rubber-coated clamp assembly (furnished in 50BB fastener package) to hot gas line bracket (Fig. 3). CHANNEL AND PLATE ASSEMBLY - Figure 3 illustrates correct assembling and positioning for this assembly. Remote Piping - For 09BB remote installation, select pipe sizes according to length from the following table. Table 2 - Remote Pipe Sizing (in.) UNIT 50BB LENGTH OF PIPE 0-15 (ft) 16-25 (ft) 26-5...
