4.Install the plug covers back when the check is complete.
START-UP PROCEDURE
2.Connect the power cord to power then turn on the main switch on ERV for start-up.
If the ERV does not run, please check the wiring connections.
1.Fill in beginning time on the OA filter before starting up the unit.
The method of remove and install OA filter please refer to P.17~P.18 (Fig.20~22)
and P.18 (Fig.24~25).
3.Remove plug covers in plugs on frame cover and check static pressure.
Using a magnehelic gauge, measure the differential pressure of fresh air and exhaust air
respectively, then adjust the dampers for balancing airflows to make the test value reach
the differential pressure of setting volume as shown below.
<Control panel>
EA knob:
Set the exhaust air volume with this knob.
The factory default is 100 CFM.
ASHRAE time knob:
The operation state will be changed with this knob. It is in units of
1 hour, for example: set to “10”, 10 minutes (ON) 50 minutes (OFF) 10 minutes (ON)...
cycle operation. The factory default is 60 min/h.
Main switch:
Power on or off for ERV. Push the main switch
completely to the on/off position when turning on/off.

SA knob:
Set the supply air volume with this knob.
The factory default is 100 CFM.
The unit will consume some electricity unless you turn off the main switch.
OPERATION
Note
The SA air volume is limited less than “EA air 20 CFM” when the outdoor
temperature is -22 °F (-30 °C)~14 °F (-10 °C). For example, when the EA air volume
setting is 50 CFM and the SA air volume setting is 100 CFM, actually the EA air volume
will be 50 CFM and the SA air volume will be 70 CFM.
