Fixing the hot water module
to floor
• Be sure to install the hot
water module in a place able
to bear its weight.
If strength is insufficient, the unit
may fall down resulting in
human injury.
• Perform specified installation
work to protect earthquakes.
If the hot water module is
imperfectly installed, an
accident by falling or dropping
may be caused.
• Drain water is discharged from
the hot water module.
(Especially while operating)
Install the hot water module in a
place with good drainage.
• For installation, be careful of the
strength and level of the
foundation so that abnormal
sounds (vibration or noise) are
not generated.
• Be sure to install the hot water module in a place
strong enough to withstand its weight. If the base is
unstable, reinforce with a concrete base.
• The hot water module must be anchored on a level
surface. Use a level to check after installation.
• If the hot water module is installed near a room
where noise is a problem, using an anti-vibration
stand on the base of the unit is recommended.
1. Fix the hot water module with M8 anchor bolts at 4
positions. 20 mm projection is appropriate for an
anchor bolt.
(Unit: mm)
• Anchor bolt positions are as shown below:
