Setup & Adjustments
1. The ERV unit must have its own disconnect.
2. Check for appropriate wiring diagrams.
3. Before providing power to the ERV unit be sure all
access doors are shut tight. Door interlock switches
will interrupt power if doors are open.
4. Power unit and inspect both blowers and ERV wheel
to ensure operation.
5. Important:
For highest effectiveness the inlet and exhaust
fl ow should be equal across both sides of the
ERV wheel. Setting the appropriate blower
speed requires that the installer determine the
application's actual ventilation rate and external
static pressure. Adjust blowers to obtain the
required CFM.
6. ClimateMaster has installed an air monitoring station
in order to determine the supply and exhaust airfl ow.
In order to use this station, the installer needs to
connect a slope gage or magnehelic gage to the
airfl ow station. Both the low and high pressure fi ttings
must be used due to the fact that the airfl ow quantity is
calibrated against the pressure drop across the wheel.
