Maintenance

The 6KW, 12KW and 24KW portable dimmers are designed to be low maintenance; however, several precautionary steps will

prolongthelifeoftheelectroniccomponents.Wheneverpossible,limittheunit’sexposuretohighambienttemperatures.Take

carenottodropthedeviceandalwaysprotectthecontrolsandconnectorsfromdamage.Donotallowliquidofanykindtoenter
