Setting up the AMU (cont.)
AMU identification number
If more than one AMU is used, each AMU must be given a
unique identification number. The AMU identification number
is shown on the upper display on the side of the AMU. You
may choose any possible identification number as long as you
choose a different one for each AMU in the system.
Caution
Disconnect the power to the WCU before
opening the AMU.
To change the AMU identification number proceed as follows:
1.
Ensure power is disconnected.

Open the AMU by removing the four screws underneath
the sun cover and tilt open the lid of the case.
