A Lennox International Inc. Company 421 Monroe Street Bellevue, OH 44811 Sharp metal edges can cause injury. When installing the unit, use care to avoid sharp *48283B006* edges. Save these instructions for future reference # 48283B006 Page 1 Page 2 # 48283B006 INSTALLATION Location of Unit Outdoor units operate under a wide range of weather conditions; therefore, multiple factors must be considered when positioning the unit. The unit must be positioned to give adequate clearances for sufficient airflow and servicing. Refer to Figure 1 for installation clearances. General Read this entire instruction manual, as well as the instructions supplied in separate equipment, before starting the installation. Observe and follow all warnings, cautions, instructional labels, and tags. Failure to comply with these instructions could result in an unsafe condition and/or premature component failure. These instructions are intended as a general guide only for use by qualified personnel and do not supersede any national or local codes in any way. The installation must comply with all provincial, state, and local codes as well as the National Electrical Code (U.S.) or Canadian Electrical Code (Canada). Compliance should be determined prior to installation. When servicing or repairing HVAC components, ensure the fasteners are appropriately tightened. Table 1 shows torque values for fasteners. Inspection of Shipment Upon receipt of equipment, carefully inspect it for possible shipping damage. If damage is found, it should be noted on the carrier’s freight bill. Take special care to examine the unit inside the carton if the carton is damaged. Any concealed damage discovered should be reported to the last carrier immediately, preferably in writing, and should include a request for inspection by the carrier’s agent. If any damages are discovered and reported to the carrier DO NOT INSTALL THE UNIT, as claim may be denied. Check the unit rating plate to confirm specifications are as ordered. Figure 1 Installation Clearances * A service clearance of 30" must be maintained on one of the sides adjacent to the control box. Clearance to one of the other three sides must be 36". Clearance to one of the remaining two sides may be 12" and the final side may be 6". A clearance of 24" must be maintained between units. 48" clearance required on top of unit. Maximum soffit overhang is 36". 36* 36 36* 36 Slab Mounting When installing unit at grade level, install on slab high enough above grade to allow adequate drainage of water (see Figure 2). Top of slab should be located so runoff water from higher ground will not collect around unit. Refer to roof mounting section for barrier construction if unit must face prevailing winter winds. Roof Mounting Install unit at a minimum of 4" above surface of the roof. Care must be taken to ensure weight of unit is properly distributed over roof joists and rafters. Either redwood or steel supports are recommended. If unit coil cannot be mounted away from prevailing winter winds, a wind barrier should be constructed (see Figure 3). Size barrier at least the same height and width as the outdoor unit. Mount barrier 24" from the sides of the unit in the direction of the prevailing winds.
