Warning
•
Verify the polarity of the power coming into the unit with a test lamp or multimeter. Connect the
multimeter or test lamp probe to the wire being tested and the other probe to ground. The black
line should be “live”. If the white line is “live” the polarity is reversed and must be corrected. If
both lines are live, the voltage is not 120VAC. The black open line from the unit should be
connected to the live line and the white open line should be connected to the neutral line. Some
unit have a safety disconnect rocker switch located just outside of the electrical control box area.
The switch disconnects the live line. Verify that it is working properly with a multimeter or test
lamp. Always ensure the ERV is properly grounded before and after testing.
Caution
•
The ERV is designed to operate with ducting. When first starting the ERV, measure the amp draw to
each motor at each speed to ensure it is operating at or below the max rating.
