WIRING INSTRUCTIONS

• Make sure power is switched off at service panel
before starting installation.
• All electrical connections must be made in
accordance with local codes, ordinances, or
national electrical code. If you are unfamiliar with
methods of installing electrical wiring, secure the
services of a qualified electrician.

This unit must be wired on a separate 15 amp
circuit.
• If your house wires do not match these colors,
you must determine what each house wire
represents before connecting and you may need
to consult an electrical contractor to determine
this safely.
1. Follow all local electrical and safety codes.
2. Never place a switch where it can be reached
from a tub shower.
