Cautions on Safety
This appliance is not intended for use by persons (including children) with reduced physical, sensory or mental capabilities, or lack of
experience and knowledge, unless they have been given supervision or instruction concerning use of the appliance by a person
responsible for their safety.
Children should be supervised to ensure that they do not play with the appliance.
Described below are the way we are gaining 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.
■ 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. (The marks described below
are samples.)
Cautions for Operation
DANGEROUS
The column with this mark shows “Impending Danger of Death or Serious Injury”.
WARNING
The column with this mark shows “Conceivable Threat of Death or Serious Injury”.
CAUTION
The column with this mark shows “Likelihood of Damage or Loss to Materials only”.
This pictorial indication shows “Prohibited”.
This pictorial indication shows “Forced Execution”.
DANGEROUS
WARNING
■ Do not use as an air circulators for
open-type burners (heaters).
When gas or oil stoves are used in
the home, separate equipment for
circulating the air should be used.
■ Don't push a finger or a stick into the air
inlet or the outlet.
A fan with a high rpm will
injure you.
■ Modification of the system is strictly
prohibited.
Improper practice of
repair could cause a
water leakage, an
electric shock or a fire.
● When the system needs a repair,
consult your dealer.
■ If there is a combustible gas leakage
from other appliances, ventilate the
room by opening windows.
If operation were to be
attempted in such a
situation, sparking at
electrical contact points
could cause an explosion.
■ 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 lead
to a lack of oxygen in the
room.
■ If the supply cord is damaged, it must
be replaced by the manufacturer or its
service agent or a similarly qualified
person in order to avoid a hazard.
■ When any abnormal condition
(scorching smell or others) is found,
stop the operation immediately and
switch the exclusive circuit breaker
“OFF”.
If you continue the operation without
removing the cause, it could cause an
electric shock or a fire.
● When the system needs a repair,
consult your dealer.

Cautions on Safety
Cautions for Installation
Cautions for Operation
CAUTION
■ It is strictly prohibited to place a
container of combustible gas or liquid
near Energy Recovery Ventilators or to
spray it directly with the gas or liquid.
It could cause a fire.
■ Do not use outside the rated voltage.
It could cause a fire or an
electric shock.
■ Combustion apparatus should not be
placed allowing a direct exposure to
wind of Energy Recovery Ventilators.
Incomplete combustion
could occur on the
apparatus.
■ Don't blow directly towards animals or
plants.
Likely to cause bad effect on animals
and plants.
■ Don't put a container of water on
Energy Recovery Ventilators.
When water spills, it is
likely to enter inside the
unit and degrade electric
insulation, possibly
resulting in an electric
shock.
■ Do not wash Energy Recovery
Ventilators with water.
It could cause an electric
shock.
■ Do not handle switches with a wet
hand.
It could cause an electric
shock.
■ If Energy Recovery Ventilators are not
used for a long period of time, switch
the exclusive circuit breaker "OFF" for
safety reasons.
If the power is left on, any build-up of
dust could cause a heat generation or
a fire.
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 Energy Recovery Ventilators when removing the
unit.
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.

Features
Main Features
1. Energy saving ventilation
Thanks to efficient recovery of thermal energy lost during Ventilation (load incurred by outside air), you can save an airconditioning fee.
2. Facility saving
Thanks to a drastic reduction of load incurred by outside air, you can make air-conditioners more compact in parallel with the
recovery of thermal energy.
3. Humidity adjusting effect
In a cooling mode, a highly humid open-air is brought near to a dehumidified room atmosphere and then supplied. In a heating
mode, a room humidity is transferred to the dry outside air and then supplied.
4. Comfortable and consistent ventilation
Ventilation is available with least possible fluctuation of a room temperature. Since exhaust and air intake are performed
simultaneously, a stable ventilation is possible even in a highly airtight room.
5. Sound shield effect
The ducts of the unit and the heat exchange element are characteristic of sound shield effect. Thus, it prevents an outside noise
from coming in the unit and also sound inside the unit from going out, so that the office and store environment can be preserved.

Specific Caution Items
Checking Location of Installation
This Energy Recovery Ventilators have been designed especially for use in offices, conference rooms, etc.
Please check to ensure that neither the main unit nor the inlet-outlet grill are installed in any of the following locations.
When Using
Locations exposed to high temperatures or
direct flame.
Avoid installing the Energy Recovery Ventilators
or the inlet-outlet grill in locations which reach
temperatures of 40°C or above.
Usage under high temperature conditions may
cause distortion of the filter or Heat Exchange
Element or motor burn-out.
Locations with high humidity.
Do not install in high humidity locations such as
bathrooms.
Doing so may cause a breakdown of the unit or
an electric shock.
Locations with large amounts of oily
smoke, such as food preparation areas.
The unit will become inoperable if the filter or
Heat Exchange Element become clogged with
oil.
Make sure that Inspection Opening is provided so that filter and
Heat Exchange Element maintenance and periodic spot checks
of the unit can be easily carried out. (Refer to the Model
Installation for its space)
Do not install the unit in locations such as machinery or chemical
plants where it will be exposed to noxious gases containing
acids, alkali, organic solvents, paint fumes, etc., to gases
containing corrosive ingredients, or where dust or oil mist will be
produced.
If there are any problems concerning the location or installation of the unit, please consult either store from which it was purchased
or the agent who installed it.
Always be sure to use a filter.
Failure to do so may cause dust and dirt to
build up on the heat exchange element,
lowering its efficiency and rendering it
inoperable.
Operate the switch with certainty.
In particular, suddenly turning the switch
on and off will not only cause improper
operation of the unit, but will also affect the
relay inside the switch, and may damage
it.
