Check and Adjust Curtain Drive-Belt Tension
Figure 15. Belt Tension Adjustment
Dymax recommends that the Curtain Drive-Belt's tension be checked at least once every three months. Follow
the instructions below to check the tension.
1.
Turn off and disconnect the Lamp Reflector Housing from the external AC source.
2.
Remove the ZIP Shutter from the Flood Lamp Reflector Housing and place it on the bench, bottom-side
up.
3.
Remove the screws that attach the ZIP Shutter's bottom panel.
4.
Very lightly press in the center of the Curtain Drive Belt with a finger; the Belt should deflect no more
than ¼" to ⅜".
5.
If deflection exceeds this value, tighten the Curtain Drive Belt by adjusting the Tension Screw in the back
of the ZIP Shutter.
NOTE: Make sure that both belts are tightened equally.
6.
Replace the bottom cover and secure it with its screws.
7.
Place the ZIP Shutter back on the Flood Lamp Reflector Housing and re-position it.
8.
Reconnect the cables and plug the AC cord into wall socket.
