Do not operate together with open-
burning appliance (e.g. gas or oil
furnaces).
→
Otherwise, it may cause
carbon monoxide poisoning.
Please use a dedicated
ventilator.
Otherwise, it may
fall off causing
personal injury.
The building structure and fixings
which are used to install the product
must have sufficient strength to
support more than 5 times the
weight of the product. They must be
reinforced if their strength is
insufficient.
Although the power is shut off, part
rotation may occur, resulting in injury.
Please pay attention to the rotation
of
impeller caused by backdraft air in
air duct.
Dropping may cause injury.
Otherwise, it may cause a safety
risk.
Be sure to have the product
transported and installed by two or
more engineers. Please pay attention
to the center of gravity and the
weight when moving the product.
Do not twist the product or
apply
excessive load to the product during
construction.
Dropping may cause injury.
Do not insert fingers or sticks into the
product air inlet, or air outlet.
Otherwise, the operation of rotation
part will cause the personal injury.
ERV Otherwise, dew may be
generated inside the
product, causing electric
shock or water dripping
and thus leading to
property damage.
Do not install the product or the
room air inlet in places where
high-temperature or high-humidity air
may enter the product.
When drilling or cutting the wall or
ceiling, do not damage the wires or
ducts in the wall.
Room air inlet
Usage in high temperature
conditions may cause
distortion of filter, heat
exchange core, or motor
burn-out.
Do not install the product or the
room air inlet in high-temperature
places (where the ambient
temperature exceeds 40 ℃) or places
in direct contact with heat sources.
Please install anti-bird netting or
similar prevention in pipe hood.
Please remove the abnormities such as
bird nests, otherwise it may cause a
lack of oxygen in room.
Otherwise, it may cause indoor air
pollution and thus may harm health.
Install the outside air inlet at a
position where the exhaust air from
the product does not directly flow
back. Otherwise, the filter may be clogged
with dust or dirt, and thus the outside
air inlet may be blocked or shorten the
service life of the filter.
Do not install the product in dusty or
dirty locations.

INSTALLATION INSTRUCTIONS
CAUTION
5
Do not place pets and plants
directly exposed to supply air outlet
or exhaust air outlet.
Otherwise, it may cause discomfort to
pets and dry out plants.
Heat-insulate the outdoor duct
(including the indoor side, if
necessary) to prevent
condensation.
When the ceiling is subject to high
temperature and high humidity,
install a ventilator on the ceiling.
Do not install the product in an
environment where the indoor
temperature is significantly lower
than the outdoor temperature.
If heat insulation is not adequate,
condensate may enter the property
causing damage.
Otherwise, it may cause fire and electric
leakage.
Otherwise, it may cause condensation,
electric shock and malfunction.
INSTALLATION AND OPERATING REQUIREMENTS
■
■
■■
■
It must operate with filter.
If filter is not used, heat exchange core will
be clogged with dirt and dust. The
performance of the product will be
affected, and the product may no longer
operate.
Turn on/off the switch correctly.
If repeatedly turning on or off the
switch, it will affect the product
operations and damage the relay
in the product.
To avoid accidents, the product
shall be installed at least 2.3 m
above the ground level.
(1) Excessive bending (2) Multiple bends. (3) Reduction in diameter of connecting
duct
■Please avoid the following duct installation.
It may cause the unexpected operation.
Ceiling board
ERV

＞2.3 m
Do not use the「Normal ventilation」
during winter.
Condensation will be produced inside the
supply air outlet if operation mode
「Normal ventilation」is used in a heated
room during winter.

INSTALLATION AND OPERATING REQUIREMENTS

Outdoor air condition
Temperature range -10 ℃
～ 40 ℃
relative humidity 85% or less.
Indoor air condition
Temperature range -10 ℃
～ 40 ℃
relative humidity 85% or less.
For example: Indoor air conditions
During cooling period: temperature 27 ℃
relative humidity 50%
During heating period: temperature 20 ℃
relative humidity 40%
Installation requirements:
same as the indoor air conditions.
Using condition
The indoor air here refers to the air in a
living room equipped with an air conditioner.
Do not use this product in refrigerated
warehouses or any other places where the
temperature changes sharply even if the
temperature falls within the above
temperature range.
Using conditions & Precautions
As shown in the following figure, it is supposed
that a high temperature absorbing air condition A
and a low temperature absorbing air condition B
are plotted on the line figure, then a high
temperature air A is exchanged by the unit
and Point C represent the trend of saturation
curve. In this case, it will cause dew or frost
inside the unit. To avoid this, you are required to
heat low temperature air from B to B’ to get C'
below saturation curve before entering the unit.
Be careful of frost and dew
1. Energy saving ventilation
Thanks to efficient recovery of thermal energy lost during Ventilation (load incurred by outside air),
you can save an air-conditioning 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 core 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.
6. RS485 central control
The energy recovery ventilator is connected to a remote control(optional) with RS485 function for
central control management by BMS or similar.
7. Outdoor filters
Outdoor filters conform to F7 class of EN 799 standard.
