Connecting Wires and the Ground Wire
• Use double insulated copper wire with 600V insulation.
• Use copper conductors only.
• Follow all local electrical codes.
Power Supply Cable and Ground Wire
• Use copper conductors only.
• Follow all local electrical codes.
NOTICE
The the indoor unit is powered from the outdoor unit, depending on
local code, a disconnect switch needs to be installed to a power sup-
ply circuit.

• To prevent condensation, insulate the two refrigerant pipes.
• Refrigerant pipe bending radius must be 4 in. (100 mm) or more.
Be sure to use the insulation of specified thickness (refer to Table 5).
Excessive insulation may cause incorrect installation of the indoor
unit, and too little insulation may cause condensate to form.
• The unit has flared connections on both indoor and outdoor sides
• Remove the valve cover from the outdoor unit then connect the
pipe
• Refrigerant pipes are used to connect the indoor and outdoor units
• Be careful not to crush or over bend the pipe in pipe bending
• Refrigerant adjustment
• If pipe length exceeds 25 ft. (7.5 m), additional refrigerant (R410A)
charge is required (The outdoor unit is charged with refrigerant for
pipe length up to 25 ft. [7.5 m]).
