Cautions on Safety
Cautions for Operation
Cautions for Installation
CAUTION
■
The system should never be used for any other purposes
than intended such as for preservation of foods, flora and
fauna, precision devices or work of art.
●
It could cause deterioration of foods or other problems.
■
Don't incline Heat Exchange Ventilators when taking them
out.
Otherwise, water remaining inside is likely to
drop and wet the furniture or other property.
●
Ask the sales office or the engineering shop to perform
the work.
CAUTION
■
Install at a stable place of sufficient
strength.
Please note that there
might be some places not
strong enough to install
due the structure of
building.
■
Do not install in locations where
harmful or corrosive gasses may be
present (i.e. acidic, alkali, organic
solvent, paint gasses etc. from
machinery or factories)
Installation in such a
location could cause a
gas-poisoning and a
fire.
■
Provide an exclusive circuit breaker
that can completely break contacts on
all the poles by more than 3mm through
direct connection to the power
terminals.
Depending upon the environment for
installation, it becomes necessary to
install an earth leakage breaker.
Unless the earth leakage
breaker is installed, it could
cause an electric shock.
●
Ask the sales office or the
engineering shop to perform the
work.
■
Do not install in locations where oily
smoke or soot may be present.
There is a possibility that
oil will adhere to the filter,
heat exchange element
etc. and make operation
impossible.
■
Never fail to install the unit inside the
heat insulting walls or, in other words,
in the space insulated from the open
air.
If you install it outside or in the space
equivalent to the open-air conditions,
dew is condensed inside the body in
the winter season.
■
Do not install in locations with high
humidity, such as close to bathroom
etc.
Installation in such a
location could cause a
breakdown.
