All phases of this installation must comply with NATIONAL, STATE, AND LOCAL CODES. WARNING: HAZARDOUS VOLTAGE Failure to follow this warning could result in property damage, severe personal injury or death. 1. Key to symbols and safety instructions Disconnect all electric power, including remote disconnects before servicing. Follow proper lockout/tagout procedures to ensure the power cannot be inadvertently energized. 1.
WARNING: HIGH CURRENT LEAKAGE Position unit where water, snow or ice from roof or overhang cannot fall directly on unit. Failure to follow this warning could result in property damage, severe personal injury or death. Grounding is essential before connecting electrical supply. Position the outdoor unit a minimum of 12’’ from any wall or surrounding shrubbery to ensure adequate airflow. See Figure 2 and Figure 3. 2. Unit location considerations Cold climate considerations (heat pump only) 2.
The pad must be high enough above grade to allow for drainage. The pad location must comply with National, State and Local codes.

Figure 11 6. Refrigerant line routing 6.1 Precautions Figure 10 Take precautions to prevent noise within the building structure due to vibration transmission from the refrigerant lines. For example: 5.5 Reuse existing refrigerant lines When the refrigerant lines have to be fastened to floor joists or other framing in a structure, use isolation type hangers. Isolation hangers should also be used when refrigerant lines are run in stud spaces or enclosed ceilings.
Feet Maximum Wall Isolator 8 Feet Maximum Side View Line Set Secure Suc tion Line using isolators every 8 feet . Secure Liqu id Line directly to Suc tion Line using tape, wire, or other approp riate method every 8 feet.
4. Wrap a wet rag around the valve body to avoid heat damage and continue the dry nitrogen purge (Figure 19). 7. Refrigerant line brazing 7.1 Braze the refrigerant lines Braze the refrigerant lines to the service valves. 1. Remove caps or plugs. Use a deburing tool to debur the pipe ends. Clean both internal and external surfaces of the tubing using an emery cloth.
1. Evacuate until the micron gauge reads no higher than 350 microns, then close off the valve to the vacuum pump. 8. Refrigerant line leak check 8.1 Check for leaks 1. Pressurize the refrigerant lines and evaporator coil to 150 PSIG using dry nitrogen. 0350 Microns 150 PSIG ON OFF Figure 23 2. Observe the micron gauge. Evacuation is complete if the micron gauge does not rise above 500 microns in one (1) minute.
