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.

Otherwise, the purification efficiency
may decrease.
CAUTION
About the service life of the filter
Cleaning Replacement
About once a month
About once a month
About once every four to six months
Protect your eyes when cleaning or replacing the
filter. Otherwise, dust attached on the filter may
enter your eyes. If necessary wear eye protection.
To prevent the dust adsorbed on the filter from diffusing in the room during cleaning, please clean
the filter outdoors or use a vacuum cleaner that can remove PM2.5 particles.
The service life of filter is set based on the operation of 10 hours every day.
The air volume and purification efficiency may decrease depending on the operating environment
and time. When cleaning the outdoor filters, if you observe that the side to which the arrows of the
outdoor filters point become black, please replace the outdoor filters in time.
If the product is used in an excellent environment and the concentration of particles with diameter
below 2.5 µm is lower than 50 µg/m3, the deviation of test data may be large due to the accuracy
of the test instrument, leading to the decrease of the purification efficiency calculated based on the
above test data.
If the energy recovery ventilator is used for a long time, the outdoor filters of the energy recovery
ventilator will be blocked by dirt and dust, which will cause the decrease of the air exchange volume
and air exchange effect, leading to louder noise. Please clean the outdoor filters regularly according
to the amount of dirt and dust attached to the filters.
If the product is used in a harsh environment (dusty area), the air volume and purification
efficiency of the product may decrease drastically. To maintain the performance of the product,
please increase the frequency of cleaning or replacing the outdoor filter appropriately.
The replacement standard is evaluated according to the independent benchmark of the company.
The actual operating environment may be different.
The test instrument used by the company is TSI 8530.
