Operating instructions

RenewAire EV Premium Airflow is a device designed to help you achieve optimal airflow in your home or office. It features two fans, one for outdoor air and one for return air, that can be adjusted independently to create the perfect balance of fresh and stale air. The EV Premium Airflow also has a built-in manometer that allows you to measure the differential static pressure across the core, so you can be sure that your airflow is set at the correct level.

Here are some of the benefits of using the RenewAire EV Premium Airflow:

  • Improved indoor air quality: By bringing in fresh outdoor air and exhausting stale indoor air, the EV Premium Airflow can help to improve the overall air quality in your home or office. This can lead to a number of health benefits, including reduced allergies and asthma symptoms, improved sleep, and increased energy levels.

BALANCING
Balancing an airflow is done by setting the Outdoor Air fan speed and then adjusting the Return Air fan speed to
eject the same or somewhat less air to the outdoors.
Equipment required for testing airflows:
u A magnehelic gauge (or manometer) or other device capable of measuring 0–1.0 in. w.g. of differential pressure.
u 2 pieces of natural rubber latex tubing, 1/8" I.D., 1/16" wall thickness works best.
Manometers are relatively inexpensive devices that are readily available from online retailers. Accuracy within
the range of 0–1.0 in. w.g. is the critical measure. Water manometers generally have graduations of 0.1" that are
difficult to accurately determine. For all manometers, there are two plastic tubes that connect at the manometer
and then the other ends go to pressure ports on the EV Premium.
Individual differential static pressures (DP) are measured ACROSS the core, using the installed pressure ports
located on the removable door.

u Verify the unit has clean filters in place.
u Open the pressure port caps for the OA airstream and then insert the tubing into the openings about 1".
u Take a differential pressure reading for the OA airstream and compare the pressure drop to the chart on the unit
or in the IOM to obtain the CFM. Adjust the potentiometer marked OA-L to obtain the desired CFM. Record the
CFM setting for future reference.
u Take a differential pressure reading on the RA airstream and compare the pressure drop to the chart on the
unit to find the CFM of the RA airstream. Adjust the potentiometer marked RA-L to obtain the desired balance.
Record the CFM setting for future reference.
u Install a jumper between the 24V and High Speed terminals to force the unit into Boost (high speed) mode.
u Repeat the process for both airstreams to set both the CFM and balance using the OA-H and RA-H
potentiometers. Record the CFM setting for future reference.
u After adjusting the potentiometers, take additional readings as needed to verify that fan speed settings are
correct.
