Outdoor Unit
Each outdoor unit is shipped with a refrigerant charge adequate to operate the outdoor section with an indoor matching coil or air handler.These units include the proper amount of refrigerant for an additional 15 ft. of refrigerant lines the same size as the valve fi ttings.
NOTE: DO NOT USE ANY PORTION OF THE CHARGE FOR PURGING OR LEAK TESTING.
Matching coils and air handlers may be shipped with a small holding charge to pressurize them to keep out contaminants.To release the pressure, read the indoor section installation instructions carefully.
Liquid and Suction Lines
Refrigerant grade copper tubing should be used when installing the system. Refrigerant suction line tubing should be fully insulated.
Field Connections for Electrical Power Supply All wiring must comply with current provisions of the “National Electrical Code” (ANSI/NFPA
70)and with applicable local codes having jurisdiction. The minimum size of electrical conductors and circuit protection must be in compliance with information listed on the outdoor unit data label.
SITE PREPARATION
Unpacking the Equipment
Remove the shipping carton and User’s Manual from the equipment.Take care not to damage the tubing connections when removing the carton.
Inspect for Damage
Inspect the equipment for damage prior to installing the equipment at the job site. Verify coil fi ns are straight. If necessary, comb fi ns to remove fl attened or bent fi ns.
Preferred Location of the Outdoor Unit Survey the job site to determine the best location for mounting the outdoor unit.Overhead obstructions, poorly ventilated areas, and areas subject to accumulation of debris should be avoided. The outdoor unit should be installed no closer than 18 inches from the outside walls of the facility and in an area free from overhead obstructions to ensure unrestricted airflow through the outdoor unit.
Facility Prerequisites
Electrical power supplied to the unit must be adequate for proper operation of the equipment. The system must be wired and provided with circuit protection in accordance with local building codes.
Minimum Circuit Ampacity
Electrical wiring to the equipment must be compatible and in compliance with the minimum circuit ampacity listed on the outdoor unit data label.
Maximum Fuse / Circuit Breaker Size Circuit protection for the outdoor unit must be compatible with the maximum fuse/circuit breaker size listed on the outdoor unit data label.
INSTALLING THE INDOOR UNIT
The indoor unit (air handler, furnace, etc.) should be installed prior to the routing of refrigerant piping. Consult the Installation Instructions of the indoor unit for installation details.
INSTALLING THE OUTDOOR UNIT
Slab Mount
The site selected for a slab mount installation requires a stable foundation and not subject to erosion. The slab should be level and anchored (if necessary) prior to installation on the slab.
Cantilever Mount
The cantilever mount should be designed with adequate safety factor to support the weight of the equipment, and for loads subjected to the mount during operation. Installed equipment should be adequately secured to the cantilever mount and levelled prior to operation of the equipment.
