Be careful of frost and dew
The Energy Recovery Ventilator manufactured by our company is conducted the condensation without the
water dropping test in the following conditions based on JIS B 8628:2003,if using condition is rougher than
the following sheet, it may cause the frost or dew.
JIS B 8628:2003Energy Recovery Ventilator AppendixF (specification)condensation test method
Relative humidity is calculated according to JIS B 8628:2003.
Energy Recovery Ventilator is intended to exchange outdoor air and indoor air. When the outdoor air comes in,
maybe bring the insects from outdoor pipe hood to internal unit. As insect occurrence is affected by natural
environment, it’s recommended to use the pipe hood with fly net when using the unit under the environment of
many insects such as near the street light.

As shown in the right figure, it’s supposed that a high temperature absorbing air condition A and a low
temperature absorbing air condition B are plotted on the air line figure, then a high temperature air A is
heat-exchanged 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.
Locations exposed to high
temperature or direct flame.
Avoid installing the ERV in locations
which reach temperature of 40ćor
above. Usage under high temperature
conditions may cause distortion of the
filter or heat exchange core or motor
burn-out.
Locations with high humidity.
Do not install in high humidity
locations such as bathrooms. Dew
occurred in unit may cause electric

FEATURES
Thanks to efficient recovery of the thermal energy lost during ventilation (fresh air
load), you can save an air-conditioning fee.
Thanks to a greatly reduction of fresh air load, part of the thermal energy is recovered
so that the air-conditioning can become mini-type properly.
When cooling, reduce the outdoor air humidity to make the incoming air humidity
close to the indoor humidity;
When heating,raise the outdoor air humidity to make the incoming air humidity close
to the indoor humidity.
Indoor temperature fluctuation is small when ventilating. As the simultaneous
performance of exhaust air and supplyair, it can be ventilated in high density space.
The air duct and heat exchange core has the effect of sound isolation. It prevents the
outdoor noise from coming in, reversely it also works so as to keep a nice office and
store environment.
1. Energy saving ventilation
2. Facility saving
3. Humidity function
4. Comfortable ventilation
5. Sound isolation
USING CAUTIONS
It must operate with filter.
If not using the filter, heat exchange
core is clogged with dirt and dust,
performance will be lowered and
even the unit doesn’t work.
Turn on /off the switch correctly.
If repeatedly turning on or off the
switch not only cause the wrong
operation but affects the relay
inside and damage it.
It’s forbidden to use theĘnormal

Heat exchange:to get the temperature and humidity close to indoor,it heat-exchanges the outdoor and indoor
air and then bring the outdoor air to indoor.
Normal ventilation: when the indoor air is polluted, it will increase the exhaust air amount.
ĆCaution: with the exhaust air amount increasing,the negative pressure will be produced in room,the outdoor
air comes into the room from the gaps of door,window and etc.so if you don’t wish the outdoor air to come into
the room, don’t use the mode.
HANDLING METHODS ON ABNORMAL OPERATION
If treated as fault:
Please check as the following list, if abnormal operation occurs, you should turn off the switch, cut off the breaker,
and get the contact with sale shop or repair shop.
Situation Solution
The unit doesn’t work when
turning on the switch.
Without air blowing
Is the breaker in the modeĘoffę?
Is there a power failure?

ceiling suspension is above)
Fix the screws and washers (separately buy).
Install the unit horizontally.
Please adjust the length of ceiling suspension bolt
to ensure the distance between the downside of unit
and ceiling is over 25mm, the distance between the
upside of unit and the mounting face of ceiling
suspension bolts is over 20mm.
Seal the junction of an adaptor and a duct by
adhesive tape or seal tape (separately buy) to
prevent any air leakage.
Please don’t touch the fan motor by hand during the
air duct construction.
Install the ducts (2) connected with outside shall
incline to outside. (gradient: 1/100~1/50).

Connection with power(Connection before ceiling construction)
Wire connection diagram
Precaution during the wire connection:
ƽThe dashed line as shown in the figure must be conducted on spot by construction personnel.
ƽPlease use the switch, its contact point sepate distance is above 3mm.
ƽPlease use the switch,its rate current is above 10A.
ƽIt’s recommended to use the wire for connecting power supply cord and switch,its rate voltage is 300V/500V
as stipulation of 60227IEC53 (soft wire).
At this time, please use the three-core wire containing green/yellow wire for power supply cord; besides, use the
two-core wire for connecting SW1, SW2 and switch inside the unit;use the two-core wire for Aircon
operation(please omit the connection if it’s not used the Aircon operation);use the four-core wire for connecting
other terminal parts and switch, the nominal cross-section area for above-mentioned wire is 2.5mm2.When it’s used
the remote control for switch,the wire connected with switch,its cross-section area is 1.5mm2.
ƽPlease use the torsion below the 1.2N to firmly connect the lead wire and terminal parts,no loosen of
connection.Please note the power supply cord in connection is not adhesive with solder.
ƽAir volume can be adjusted to two modes of high+low and strong+low.
Factory setting is mode of high +low. Please adjust it as customer required if necessary.
ƽWhen adjusting the air volume from high to strong, please separate the connector of the red line and the blue
line, and link the connector of red wire and white wire (shown as chain dotted line).
ƽSeveral units operate, the total current for all equipment must be less than the half rate current of switch.
ƽGround connection is required.
ƽAfter completing the wire connection, please fix the cover of switch box by the screws.
ƽWhen the power supply cord is damaged, in order to avoid the danger, please entrust the authorized personnel
to conduct the changing work, and get the contact with the sale shop and repair shop where you purchased.
wirig diagrams of lefe tyfe and right

Wire connection
Peel off the skin of power supply
cord by 40mm, and peel off the
skin of each core wire by 10mm.
The power supply cord goes through the wire plug, as
required in figure, fix the wire connecting power supply cord
and switch in the terminal block,and fix the ground wire in the
ground terminal.
Connection proportion of Lead wire is not forced by strength,
fixing the wire connecting the power supply cord and switch.
In maintenance, in order to avoid pulling the switch box into
the unit, please keep enough space for the wire connecting
the power supply cord and ground wire. To prevent it from
touching the ceiling, please fix it by ceiling suspension bolts.

After completion, never fail to check the ground wire connection and wiring and conduct the trial operation.
Check the display of switch and airflow condition with power on after confirmig the wiring connection, power
and voltage.
Ventilation/stop
Confirm the air volume is changed as the power on/off
Heat exchange (see the damper closed by opening side maintenance opening )
Normal ventilation (see the damper open by opening side maintenance opening)
Abnormal operation occurs, cut off the special purpose circuit breaker and confirm the wire connection again.
Fix the cover of switch box after conducting the trial operation.
Please stick the model label to the switch or around.
Model label is placed in the plastic bag, don’t forget to attach it.

Explanation:
The values shown as instruction are measured in the condition of total pressure when ERV operates.
The input power indicated in name plate is the maximum value at the static pressure of 0 Pa.
Noise value is measured at the position 1.5m away from the down side of the unit based on standard JIS B 8628:2003
(measured in the complete anechoic room), the value is affected by the echo during the actual installation, more than the
indicated value.
In the case of other condition is unchanged, noise value is up for 1.5dB(A) measured in the half anechoic room.
