Cautions on Safety
Cautions for Installation
Make sure the system is
■
grounded.
Grounding cable should never be
connected to a gas pipe, city water
pipe, lightning conductor rod or
grounding cable of telephone. If the
grounding cable is not set properly, it
could cause electric shocks.
Cautions for Maintenance
Remove a product if it is not
■
being used. Do not leave
the disused product as it is.
The disused product
might drop, causing
personal injury.
CAUTION
Do not install the product in
■
an environment where the
room temperature may be
significantly lower than the
outside temperature.
Doing so may result
in electric shock or
fire.
CAUTION
When cleaning filters or heat
■
exchange elements, be sure to
turn off the switch and turn the
dedicated breaker to the "Off"
position in advance.
As the fan rotates inside
at high speed, failure
to do so may result in
personal injury. When
working in an elevated
position, firmly secure the
step ladder.
Never Fail to Observe
Be sure to ask a
■
specialized installation
service shop to carry out
installation work.
The filter should be cleaned
■
regularly.
Dust or dirt building-
up on it can lead to
a lack of oxygen in
the room.
Use gloves when cleaning
■
the filter or heat exchange
element.
Doing so will reduce
the possibility of injury.
Otherwise,
personal injury
could result.
