• Secure the separate wires in the control box panel using zip ties.
• Secure wiring with accessory clamps so that it does not touch the piping.
• Use a conduit for the communications cable / power wiring from the outdoor unit to the indoor / branch distribution units.
• Make sure the communications cable / power wiring from the outdoor units to the indoor / branch distribution units, and the power wiring to
the outdoor unit are separate, otherwise, the outdoor unit operation may be affected by electrical noise and will malfunction or fail.
