PRE START-UP LE10XIN ERV 8.0 PRE START-UP 8.1 VERIFY VOLTAGES Using a voltmeter, test the input voltages as supplied to the disconnect switch. Refer to Digit 13 of the unit Configuration Code to find the rated voltage. The supplied voltage must be within +/- 10% of the rated voltage. -
Page 31: Start-Up
START-UP LE10XIN ERV 9.0 START-UP 9.1 VERIFY CORRECT FAN ROTATION DIRECTION The first time power is applied to the fan motors, it should be just a brief pulse so that the fans will begin spinning. Verify that the fans are turning the correct direction. If a fan is turning the wrong direction, it will be because a three-phase power source has been improperly connected. -
