IMPORTANT:This product has been designed and manufac- tured to meet ENERGY STAR criteria for energy efficiency. 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 effi- ciency and shorten equipment life.
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. File a claim with the transportation company.

Location
The unit is designed to be located outdoors with sufficient clearance for free entrance to the air inlet and discharge air openings. The location must also allow for adequate service access.
The unit must be installed on a solid foundation that will not settle or shift. Adequate structural support must be pro- vided. Maintain minimum clearances as shown in Figure 1 and Table 1 and install the unit in level position. Isolate the base from the building structure to avoid possible transmis- sion of sound or vibration into the conditioned space.
Using Accessory Lift Kit
Lifting Bracket
SpreadersAccessory (Field Supplied)
Sheet Metal
Screw
To avoid possible damage to unit panels from lifting clevis, place packing material between clevis and panels before lifting unit.
Figure 1
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.
Do not permit overhanging structures or shrubs to obstruct condenser air discharge inlet or outlet.
For improved
Exercise care when moving the unit. Do not remove any packaging until the unit is near the place of installation. An accessory lift kit can be purchased to aid in rigging (see
Figure 1). Spreaders whose length exceed the largest dimension across the unit must be used across the top
of the unit. Recommended spreader length: 3 ton and smaller package units – 44", 3.5 ton and larger units – 54".
