a. Using best industry standards and practices, measure the fresh air that is being brought into the classroom.
For units with one speed controller (std.), adjust the speed of the intake and exhaust blowers by inserting
a slotted screw driver into the opening on the controller. The speed controller is located on the lower
right side of the GreenWheel ERV assembly. Access to the speed controller is through the return air
grille. Measure the intake air again and adjust the speed of the blowers. Repeat as necessary to meet
the fresh air requirements.
b. For units with the optional variable fan speed controller for the GreenWheel
®
ERV exhaust blower, first
measure the air being introduced into the classroom using best industry standards and practices. Adjust
the speed of the intake air GreenWheel ERV blower until the required outside air is being brought into
the classroom.
c. Now measure the exhaust air from the classroom. Adjust the speed of the exhaust air GreenWheel
ERV blower until the required air is being exhausted from the classroom. The exhaust air controller is
located on the lower left side of the GreenWheel ERV assembly. Access to the exhaust air controller
is through the return air grille. It is usual practice to pressurize the classroom by exhausting slightly
less air than is being brought into the classroom.
Evaporator Variable Fan Speed Controller (Optional)
Indoor evaporator fan controller is accessed through the return air opening. The controller is located on the
GreenWheel ERV assembly on the air separation box in a 2” x 4” “J” box.
Note: Sufficient airflow is required for proper operation of the unit.
