Disconnect all remote power supplies before installing or servicing any portion of the system. Failure to disconnect power supplies can result in property damage, personal injury, or death. WARNING Installation and servicing of air conditioning equipment can be hazardous due to internal refrigerant pressure and live electrical components. Only trained and qualified service personnel should install or service this equipment. Installation and service performed by unqualified persons can result in property damage, personal injury, or death. WARNING Sharp metal edges can cause injury. When installing the unit, use care to avoid sharp edges. 506468-01 Page 1Issue 1004 Manufactured By Allied Air Enterprises, Inc. A Lennox International Inc.

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. 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. 4HP16LT condensing units use R410A which is an ozone-friendly HFC refrigerant. This unit must be installed with a matching indoor coil and line set. A filter drier approved for use with 410A is installed in the unit. IMPORTANT: This product has been designed and manufactured to meet ENERGY STAR criteria for energy efficiency when matched with appropriate coil components. However, proper refrigerant charge and proper air flow are critical to achieve rated capacity and efficiency. Installation of this product should follow the manufacturer’s refrigerant charging and air flow instructions. Failure to confirm proper charge and airflow may reduce energy efficiency and shorten equipment life. 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 Torque Table Table 1 Fastener Torque Stem Caps 8 ft. lbs. Service Port Caps 8 ft. lbs.

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 * • Place a sound-absorbing material, such as Isomode, under the unit if it will be installed in a location or position that will transmit sound or vibration to the living area or adjacent buildings. • Install the unit high enough above the ground or roof to allow adequate drainage of defrost water and prevent ice buildup. • In heavy snow areas, do not locate the unit where drifting snow will occur. The unit base should be elevated above the depth of average snows. 506468-01 Issue 1004 Page 3 NOTE: Elevation of the unit may be accomplished by constructing a frame using suitable materials. If a support frame is constructed, it must not block drain holes in unit base. • When installed in are...
