Improper practice of installation could cause
an electric shocks or a fire.
Carry out the installation accurately in line
with this instruction.
Fault or electric leakage cause the electric shock.
Ground connection.
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. The external air
intake opening should not be positioned
where discharged air may directly enter
it. A situation like this lead to the room
beiy contaminated and this may pose a
healthy risk.
Please conduct the ground connection in the following
methods.
If employing other methods, it may cause the
insufficient ground connection. Don’t connect the
ground connection with gas pipeline, water pipeline,
lightening rod and phone landline. Wrong ground
connection may cause electric shock.
When you want to pierce the metal duct
through the metal lathe 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 electrical
shock or electric leakage.
It may cause the fire and electric shock.

It may cause the injury.
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
breaker is used. Any insufficient capacity
of power circuit and improper work can
result in shock and fire hazard.
Choose the installation 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 operation
instruction. Otherwise, it is likely to cause
an electric shock, a fire, a drop of unit,
thus causing the injury on the human body.
Dropping may
cause the injury.
Please don’t insert the fingers and sticks
into the rotation part during the operation.
Please install the main unit in location
where dust and dirt can’t come in.
Large amount of dirt and dust clogged in
filter will cause the lack of oxygen in room.
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.
Owing to the different installation position
for special purpose circuit breaker,
sometimes it’s required to install the
anti-creeping circuit breaker.
It may cause the electric leakage if not
installing the anti-creeping circuit breaker.

protective tools to avoid the injury.
It must use the specified part during the
installation (include the accessories).
It may cause the unit dropping, fire and
electric shock if not using the specified parts.
Please install the anti-bird net or similar
thing in air duct.
Please remove the abnormities such as bird
net, otherwise it may cause the lack of
oxygen in room.
Install the outdoor duct in a falling gradient
towards the outside so as to prevent water
from coming in.
Otherwise, the building is likely to be
flooded, wetting the household effects.

(1) excessive bending (2) multi-times bending (3) reduction the diameter of connecting duct
Please avoid the following duct installation.
It may cause the unexpected accident.
Please don’t install the unit in location
where indoor temperature is below the
outdoor temperature.
It may cause the electric shock or
abnormal operation.
Provide an exclusive circuit breaker that
can completely contacts on all the poles
by more than 3mm through direct
connections to the power terminals.
Depending upon the environment for
installation, it becomes necessary to install
an earth leakage breaker.
Don’t install in location where may be
exposed to the combustible gas leakage.
In case of gas get together around the unit,
it may cause the fire.
Connect the power cord and the lead wire
with accuracy using the specified wires
and fix them firmly so as not to put the
outer stress of wires on the pin connecting
area. Incomplete connection or fixing is
likely to cause a heat generation or fire.
Please don’t face it to the air outlet
(especially when operating).
The dirt may fly into your eyes.
Don’t twist the unit or
conduct the overload
force to unit in construction.
Dropping may cause the injury.
Install the power cord and the lead wire
with accuracy so the power source cover
may not float. If the installation curves
inappropriately, the pin connection area is
likely to cause a heat generation, a fire and
an electric shock due to dust or powder.
Please take care of it during moving the
unit.
Improper hanging and moving may cause
the dropping, result in injury.
Although the power is shut off, it may get
involved to the rotation part, result in injury.
Please pay attention to the rotation of
impeller caused by backward air in air duct.
Please firmly install the product and
components.
Otherwise, it may cause the injury brought
by falling-off.

Locations with large amounts of cooking fumes.
The unit doesn’t work if the filter or heat exchange core
become clogged with oil which may cause fire.
Locations exposed to high temperature or direct
flame.
Locations with high humidity.
Avoid installing the ERV in locations which reach
temperature of 40 or above. Usage under high
temperature conditions may cause distortion of filter
or heat exchange core or motor burn-out.
Don’t install it in the following locations.
Make sure that inspection opening is provided so that filter and heat exchange element maintenance and
periodic spot checks of unit can be easily carried out.
Don’t 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.
(Gas poison, corrosion and degradation accrued in
unit may cause the fire.)
Do not install in high humidity locations such as bathrooms.
Dew occurred in unit may cause electric shock, short circuit,
other electric accident and produce the dewing water drops.

temperature absorbing air condition B are plotted on the line figure, then a high temperature air A is
heat-exchange by the unit and Point C represent the trend of saturation curve. In this case, it will cause the
dew or frost inside the unit. To avoid this, you are required to heat a low temperature
air B up to B’ so as to get C’ below the saturation curve before using the unit.
Avoid the entering of insects

FEATURES
1. Energy-saving You can save the electric bill for air conditioner as a result of recovering the loss of
energy caused by ventilation.
2. Facility saving As part of energy can be recovered through greatly reduction of fresh air load, the
similar air conditioning equipment can be properly miniaturization.
3. Humidity function When it's heat in room,reduce the humidity of outdoor fresh air to make it close to that
of indoor.
When it's cool in room, increase the humidity of outdoor fresh air to make it close to that
of indoor.
4. Comfortable ventilation The indoor temperature varies little during ventilation, it also can be used for ventilation
in high enclosed room due to the simultaneously operation of air supplying and
discharging.
5. Isolation effect There's isolation effect in air path and heat exchange core,which will prevent the
outdoor noise from spreading to indoor or prevent the indoor sound from spreading to
outdoor to keep a good environment for office or shop.
