SECTION VI: SPECIFICATIONS
POWER SUPPLY AND INDOOR/OUTDOOR WIRE
CONNECTION
• The system should be powered from a dedicated circuit.
• Wiring work should be based on applicable technical standards.
• Wiring connections should be made following the provided
diagrams.
• Make sure all electrical connections are securely tightened.
Solid conductor AWG14 or stranded conductor AWG14 are the MINI-
MUM allowable wire sizes. There are some applications that will require
larger gauge conductors depending on the voltage and amperage rat-
ings on the data plate and the distance that the conductors will be
routed. It is the installing contractor's responsibility to properly size the
electrical conductors for the equipment and for the application.
All of the indoor units and outdoor units should have the electrical con-
ductors sized using the National Electrical Code (NEC) and the local
authority having jurisdiction whichever is more stringent. If the equip-
ment is installed outside of the United States, all local codes within the
country of origin must be followed.

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.

The Ductless indoor units must have a minimum of 14 gauge, 600
volt double insulated copper conductors. The conductors for the indoor
unit can be either solid or stranded copper. When possible the indoor
unit should have stranded wire for the communication to ensure proper
communication between the indoor and outdoor unit(s).
The Ductless outdoor units must have a minimum of 12 gauge, 600
volt double insulated copper conductors with the exception of the fol-
lowing models: DHMF30CMM42Q1,
DHMF42CMM42Q1, which require 10 gauge wire. The conductors for
the outdoor unit should be solid or stranded copper conductors.
The listed wire sizes are only minimum requirements, as previously
stated, the conductors for both indoor and outdoor units must be
sized using the NEC and local authority having jurisdiction.

• 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]).
