WARNING Improper installation, adjustment, alteration, service or maintenance can cause property damage, personal injury or loss of life. Installation and service must be performed by a qualified installer or service agency. The CB29M and CB30M units are factory−configured for upflow or horizontal right−hand discharge installation. For downflow or horizontal left−hand discharge, some field modification is required. Page 5 CB29M/CB30M SERIES 2. No further adjustment is necessary. Set unit so that it is sloped 1/4 inch toward the drain pan end of the unit. IMPORTANT Kit number 83M57 (LB−109844A) must be installed for downflow application. NOTE − For horizontal applications, an auxiliary drain pan is recommended. Refer to local codes. Disassembling CB30M Blower Coil Unit These units are shipped from the factory fully assembled. The CB30M blower coil unit’s sections may be separated to facilitate movement at some installation sites. If required, disassemble the unit as follows: 1. Remove access panels from both blower and coil assemblies. This will lighten the cabinet for lifting. 2. Remove one screw from the left and right posts inside the unit. Remove one screw from each side on the back of the unit. Unit sections will now separate. 3. To reassemble, align cabinet sections and reinstall screws. Replace access panels. NOTE − For horizontal applications in high humidity areas, seal around the exiting drain pipe, liquid line, and suction line to prevent infiltration of humid air. Right−Hand Discharge Configuration Upflow/ Downflow Drain Pan Horizontal Drip Shield Horizontal Drain Pan No Adjustment is Necessary Figure 2 Upflow Application 1. Remove access panels. Remove corrugated padding from the space between the blower and coil assemblies. 2. To ensure proper operation, remove the horizontal drain pan from units in upflow configurations (see figure 1). 3. Place unit in desired location. Make sure that unit is level. Connect return and supply air plenums as required using sheet metal screws. 4. Install units that have no return air plenum on a mounting stand at least 14" from the floor for proper air return. Lennox offers an optional upflow unit stand. (45K31 for CB29M−21, −26, and −31; 45K32 for CB29M−41 through −65.) 3. If the unit is to be suspended, it must be supported along the entire length of the cabinet (see figure 3). If using a chain or strap, attach a piece of angle iron or sheet metal to the unit (either above or below the unit), so that the full length of the cabinet is supported. Use securing screws which are no longer than 1/2 inch to avoid damaging the coil or filter. Use sheet metal screws to connect the return and supply air plenums.

After installation, pull a vacuum on the line set and coil before releasing the unit charge into the system. Downflow Combustible Base Dimensions 1-5/8 (41) Liquid Line No. Condensate Drain Filters Connect main condensate drain and route downward to an open drain or sump. Do not connect drain to a closed waste system. Refer to figure 8 for typical condensate trap configuration. IMPORTANT Filter access panel must be in place during unit operation. Excessive warm air entering the unit may result in water blow−off problems. Typical Condensate Drain Connection Minimum 1 inch (25 mm) pitch per 10 feet (3048mm) of line Trap must be deep enough to offset maximum static difference (generally, 2" [51mm] minimum). Pipe diameter difference Each unit includes a factory−installed filter. Note that filter access door fits over access panel. Air leakage will occur if access panel is placed over filter door. Coil drain pan Figure 8 It is recommended that the auxiliary drain be connected to a drain line for all units. If auxiliary drain is not connected, it must be plugged with provided cap. For downflow units, the auxiliary drain MUST be connected and routed to a drain. See figure 9 for auxiliary and main drain locations. Left−Hand Discharge Upflow or Downflow Right−Hand Discharge Filters should be inspected monthly and must be cleaned or replaced when dirty to assure proper furnace operation. Reusable filters supplied with some units can be washed with water and mild detergent. Some units are equipped with standard throw−away type filters which should be replaced when dirty. To remove filter, loosen the thumbscrews holding the filter panel in place. Slide filter out of the guides on either side of cabinet, insert new filter and replace panel. See Table 2 for replacement filter sizes. Table 2 Filter Dimensions Main drain on right Auxiliary drain on left Figure 9 The following practices are recommended to ensure condensate removal (see figures 8 and 9): 1. Drain piping should not be smaller than the drain connections at drain pan. 2. A trap must be installed in the main drain line. 3. The trap must be deep enough to offset the difference in static pressure between drain pan and atmosphere. Generally, two inches is satisfactory for medium static applications. 4. Horizontal runs must be sloped 1 inch per 10 feet of drain line to offset friction. 5. An open vent in drain line will sometimes be required due to line length, friction and static pressure. 6. Drain construction and routing should facilitate future cleaning and must not interfere with filter access. 7. Auxiliary drain should run to an area where homeowner will notice any drainage. Refer to local codes.

Warm air introduces moisture, which results in water blow−off problems. This is especially important when the unit is installed in an unconditioned area. Make sure the liquid line and suction line entry points are sealed with either the provided 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.
