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. This unit has been factory charged with a quantity of refrigerant (R22) sufficient for a matched indoor coil and 20 feet of refrigerant tubing. If installed with other indoor sections or with tubing sets other than 20 feet in length, adjustments to the total system charge must be made. This outdoor unit has been ARI rated with several Arm- strong matching indoor sections for various types of installations. To obtain optimum performance, a matched indoor section must be installed. ARI ratings are based on properly charged systems running at rated indoor cfm levels. Ductwork should be specified to insure the correct indoor airflow is obtainable. 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. Limitations This unit is designed and approved for outdoor use only. The outdoor unit must not be installed with any ductwork in the airstream. The outdoor fan is not designed to operate against any additional static pressure. The unit has been designed to operate within the range of indoor and outdoor temperatures as outlined in Table 1. Following these recommendations will minimize component failures and maximize system performance. Optimum Temperature Range 65° F* (minimum) to Outdoor 115° F (maximum) 62° F db/57° F wb to Indoor 90° F db/72° F wb * If extended run times are anticipated below outdoor temperatures of 65° F, a low ambient kit must be installed. Table 1 Location of Unit Install the unit on a solid, level mounting pad. To minimize transmission of vibration, the pad should not be in direct contact with any building walls or foundations. This unit has been designed to be located outdoors with sufficient clearance for free entrance to the inlet and discharge air openings. Adequate service clearance must also be provided. Refer to Figure 1 for a detailed description of minimum clearances. Position the unit to avoid direct contact of water, snow or ice from a roof line overhead. Avoid placing the unit near quiet areas such as sleeping quarters or study rooms. Normal operating sound levels may be objectionable if the unit is placed near certain rooms. Electrical Wiring All field wiring must be done in accordance with the National Electrical Code recommendations, Canadian Electrical Code and CSA Standards, or local codes, where applicable. Refer to the unit rating plate for information needed for wire sizing and branch circuit protection. An adequately sized branc...
