Electric Wiring - Toshiba Carrier MMY-MAP0726HT6P-UL Installation Manual

■ Pipe insulation
• Apply pipe insulation separately to liquid, gas, and balance lines.
• All insulation should have a minimum temperature rating of 248°F (120°C).
■ Finishing pipe work
1. After all piping and insulation is complete. Fill the remaining gap at the piping panel with silicon sealer.
2. If the piping was routed down or to the side, the remaining gap should be filled with silicon sealer.

WARNING
The equipment shall be installed in compliance with NEC and local codes.
CAUTION
• Do not connect high voltage power wires to the control terminal blocks (U1, U2, U3, U4, U5, U6);
• All fi eld wiring insulation rating must comply with NEC and local codes.
• All wiring must be strained relieved as specifi ed by NEC and local codes.
• Refrigerant piping and control wiring should use the same routing.
• Do not energize the indoor units until leak check and vacuuming are completed.
• For indoor unit power and control wiring see indoor unit installation instructions.
NOTE
• Use copper supply wires.
• Use UL wires rated 600V for the system interconnection wires.
• Use UL wires rated 300V for remote control wires.
