SPEED CONTROLLER
Each Krueger fan powered air terminal unit is equipped with
a fan SCR speed controller, located on the bottom of the
control box. The SCR can be adjusted in the eld. (The QFC,
size 7 unit has 2 SCR speed controllers, one for each fan. One
SCR is located in the standard position at the bottom of the
control box; the other is at the top of the control box.)
CAUTION: The minimum stop on the speed controller
is factory set at an internal minimum stop to prevent
damage to the motor. Do not attempt to override this
minimum stop or electrical damage to the fan motor
may result.
The fan airow output is dependent on the setting of the
controller and the downstream static resistance.
TO INCREASE THE FAN SPEED (RPM)
Turn the slotted adjustment on the controller clockwise
toward the “HI” marking printed on the controller faceplate.
(Refer to Figure 9.)
TO DECREASE THE FAN SPEED (RPM)
Turn the slotted adjustment on the controller clockwise
toward the “LO” marking. (Refer to Figure 9.)
