Common Installation Problems
Is the unit connected to 220V? The unit has no neutral wire, just L1, L2 and ground. To properly test for the 220V, you
must test the L1 and L2 wires together and you should get 220V. If you test individually, you will get a false reading.
Power box issues? Make sure the wiring that connects the power box to the keypad and steam generator is not
damaged.
