button is pushed?
Check!
lDoes warm air blow out from the left of the
wand when the dryer button is pushed?
lDoes the dryer turn off when the STOP button
is pushed?
Check!

the screws.
lWhen installing into sheet rock or tile,
first drill 1 5/16" deep (1/4" D (6mm))
holes into the wall and then use anchor
bolts to attach the hanger to the wall.

Anti-theft mounting blocks are contained in a seperate bag. Install the
blocks using the instructions included in the kit in order to prevent the
remote control from being removed.
4Insert the remote controller into the wall hanger.

Precaution
lBefore attaching the remote controller to the wall, make certain that
the controller works in that spot. Sit on Neorest to activate sensor.
Press "Wand Cleaning" button. If wand extends, the remote position
is good. Note that no water will be sprayed in "Wand Cleaning"
mode.·
lIf the remote controller does not
activate the toilet functions from
the selected mounting position,
try another position on the
opposite wall or refer to
the figure below for
installation guidelines.
