Refer to the
Chair Arrangement Correlation Dimension
(on pages 30 to 34) that illustrates the markings (installa-
tion position), the support legs and the base panel and
mark the position to place the floor unit.
(The A-dimension and the D-dimension depend on the chair
to use and the reclined posture.)
As for markings, rule lines as many as possible so that you
can see the layout of the water supply Pipe, the hot water
supply Pipe and the drainpipe and the floor unit position.
Arrange the support legs and the floor base panel at this
timing.
Lay pipes to meet the floor unit position marked in Step 2 accord-
ing to the
Plumbing Drawing
on page 2.
For plumbing, check the position of the support legs to hold the
floor in advance and avoid the position to lay the pipes.
※
When the floor mount high rocks pump (SP-CH) is fastened
onto the floor, pay attention to the following dimensions:
*
1
=
350 mm or more
*
2
=
85 mm or less
*
3
=
68 mm or less
Make sure that the drainpipe does not have double trapping.
Drain failure or abnormal noises may occur.
Before laying the subflooring material, cut off the
opening in the floor base panel for the unit attach-
ment position.
Check the flexural level of the floor base panel with
the opening and place additional support legs.
