A. If there is a ceiling
1) Open the hole in the installation location to the ceiling open-
ing dimensions.
2) Install the suspension bolts (procured locally) at the designated
locations.
(Use care as the center of the spacing for the suspension bolts
is not at the center of the panel.)
3) Hang the unit, use the four bolts to mount the pattern
paper provided to the panel mounting section and adjust
the height.
4) Use a level or transparent hose with water in it to confirm that
the unit is level. If the unit is not level, problems such as water
leakage or improper operation of the float switch could occur.
5) After confirming the above, secure the unit in position.

tern paper can be referred to for making the opening in the
ceiling.
3) After checking the height and that the unit is level, secure the
unit in position.
