Routine maintenance must be performed every 2 or 3 months , clogged filters
may cause condensation on the unit due to air flow reduction.
Please wear gloves to avoid pinching fingers during maintenance.
Please pay attention to dust ,condensation water or parts that may drop down
when the cover is opened.
MAINTENANCE PROCEDURE
- Open the frame cover by unlocking the latches. If not convenient for maintenance you also can turn the lock plate 90° and remove the frame cover. (Fig.3)
- Remove OA filter and RA filter to clean with vacuum cleaner. (Fig.4)
- Clean energy recovery core with vacuum cleaner. (Fig.5)
- Replace the OA and RA filters. Make sure the RA filter adapts to the convex and the direction of the arrow on the OA filter is in the same direction as the air flow displayed on the nearby label. (Fig.6)
- Reinstall and close frame cover by locking the latches then reset the lock plate. (Fig.7)
- Connect power, press filter reset button with sound of “beep” then filter indicator and buzzer sound will be off. (Fig.8)

Running indicator (Green)| Filter indicator (Red)
1.The ERV doesn’t work.| Off| Off| Check the power cord is connected. Check
the frame cover is closed.
Check the main switch in product body is on.
Check if the spring on the inside of frame cover is damaged or deformed.
On| Off| ERV running interval according to the ASHRAE time setting.
When outdoor temperature is low ( -22 °F (-30 °C), ERV stops operating
automatically. Damper may be frozen shut, please wait for maximum 24 hours for
defrosting.
2.The HVAC/AHU doesn’t work when ERV works.| On| Off| Please disconnect the
power and contact the dealer to check the HVAC/AHU wiring connect.
3.Buzzer sound (10 sec in a hour) and ERV works.| On| On| The RA filter and OA
filter need to be maintained.
If you do not want the buzzer notification, please long press the filter reset
button for 3 sec to cancel it.
4.Buzzer sound (30 sec in a hour) and ERV doesn’t work.| Blink (0.5 s)| Off|
SA motor error, please disconnect the power and contact the dealer for repair.
Blink (2 s)| Off| EA motor error, please disconnect the power and contact the
dealer for repair.
Off| Blink (0.5 s)| OA damper error, please disconnect the power and contact
the dealer for repair.
Off| Blink (2 s)| EA damper error, please disconnect the power and contact
the dealer for repair.
Off| Blink (4 s)| Center damper error, please disconnect the power and
contact the dealer for repair.
Blink (0.5 s)| On| Temperature sensor error, please disconnect the power and
contact the dealer for repair.
On| Blink* (0.5 s)| PCB board error, please disconnect the power and contact

5.ERV doesn’t work base on the setting air volume.| On| Off| When product runs
in circulation mode for defrosting, the air volume will be more than setting
and sound will be slightly louder than normal operation.
