After knocking out the holes, we recommend you paint the edges and areas around the edges
using the repair paint to prevent rusting.

Use a power wire pipe for the power wiring.
Outside the unit, make sure the low-voltage electric wiring
(i.e. for the remote control, between units, etc.) and the highvoltage electric wiring do not pass
near each other, keeping them at least 5in. apart. Proximity may cause electrical interference,
malfunctions, and breakage.
Be sure to connect the power wiring to the power wiring terminal block and secure it as
described in 7-4 Field line connection.
Inter-unit wiring should be secured as described in 7-4 Field line connection.
• Secure the wiring with the accessory clamps so that it does not touch the piping.
• Make sure the wiring and the electric parts box lid do not stick up above the structure, and
close the cover firmly.
