Read through this “Cautions on Safety” with care before installing the unit.

Described below are the way we are stimulating your attention to what you are supposed to observe to prevent dangers to the
users or other people as well as loss to the property.

Cautions on Safety

Never fail to observe the caution items described hereinafter because all of them refer to the critical matters on safety.
The meanings of the marks or indications are described below.

The degrees of danger or damage that is likely to occur due to the
wrong use ignoring the indications are categorized for explanation as
marked below.

Kinds of the items to be observed are categorized for
clarification with the following pictorial symbols.

WARNING

Never fail to ask the sales office from which you bought the unit
or the installing service shop to install the unit. If you install it by
yourself, any inappropriate installing works would cause an
electric shock or a fire.

The external air intake opening should be positioned away from
the exhaust openings of combustion gases etc. The intake of
such gases could cause a lack of oxygen in the room.

Carry out the installing works accurately in line with this
installing work manual. Improper practice of installation could
cause an electric shocks or a fire.

Netting or something similar should be provided at the external
air intake opening to prevent birds etc. interfering with the unit.
Nests or other foreign objects should be removed. That could
cause a lack of oxygen in the room.

Choose the installing place where is endurable in quality as well
as in weight, then install the unit accurately with adequate
strength and completeness of installation in accordance with the
installing work manual. Otherwise, it is likely to cause an electric
shock, a fire, a drop of the unit, thus causing the injury on the
human body.

Carry out the GND work. Never connect the GND wire to a gas
pipe, a water supply pipe, a lightning conductor, a GND line of a
telephone, etc. An incomplete GND wire is likely to cause an
electric shock.

Carry out electrical work in accordance with the laws and
regulations prevailing in the country concerned, technical
standard and explanation for work, and make absolutely sure
that an exclusive circuit is used. Any insufficient capacity of
power circuit and improper work can result in electric shock and
fire hazard.

When the system is checked and the power cable undergoes
maintenance, stop the operation, and keep the exclusive circuit
breaker "OFF".
It could cause an electric shock.

CAUTION

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.

Install the power line and the connecting line with accuracy so the
power source cover may not float. If the installation of the power
source cover is inappropriate, the pin connection area is likely to
cause a heat generation, a fire and an electric shock due to dust
or powder.

When you want to pierce the metal duct through the metal lath
or the wire lath or the metal plate of the wooden facility, do not
forget to insulate electrically between the duct and the wall.
Otherwise, it would cause an electric shock or an electric
leakage.

Never install the unit near the place where there is a fear of
leakage of an inflammable gas. If gas happens to leak and stays
around the unit, it is likely to cause a fire.

Don't use other parts than specified (including the auxiliary
parts) for installing works. If you do not use the specified parts, it
is likely to cause a drop of the unit, a fire, an electric shock, etc.

Don't use the unit at the other voltages than the rated one. It
could cause a fire or an electric shock.

Install the outdoor duct in a falling gradient toward the outside
so as to prevent water from coming in. If it is not installed so, the
building is likely to be flooded, wetting the household effects.

Do not install the unit in locations with large amounts of oily
smoke, such as food preparation areas. It could cause a fire.

Heat-insulate the outdoor duct (including the indoor side, if
necessary) to prevent dewing. If heat insulation is not adequate,
water likely goes indoor and wets the household properties.

Don't install the unit at the place of a high temperature or a flame.
It could cause a heat generation or a fire.

When it is high humid and high temperature inside the ceiling, a
ventilation system must be installed inside the ceiling. It could
cause a fire or an electric leakage.

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.

Connect the power line and the connecting line with accuracy
using the specified cables and fix them firmly so as not to put
the outer stress of the cables on the pin connecting area.
Incomplete connection or fixing is likely to cause a heat
generation or a fire.

Do not install in locations with high humidity, such as close to
bathroom etc. It could cause an electric shock or an electric
leakage etc.

Never Fail to Observe
