A. If there is a ceiling
1) Open the hole in the installation location to the ceiling
opening 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.
B. If ceiling is to be installed later
1) Follow steps A2 to A4 in the previous section "A. If
there is a ceiling" to install the unit and mount the
pattern paper.
2) When the ceiling is installed, the outer perimeter of
the pattern 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.
(d) Drain piping
1) Drain piping should always be in a downhill grade (1/50-1/100) and avoid riding across an elevation or making traps.
