VEVOR DB22 Bedienungsanleitung Seite 6

OPERATION
STEP 1：Determine what material of venting you have. If white vinyl is
currently installed, it is recommended to switch to a rigid or semi-rigid all
metal venting. White vinyl and foil vinyl can be damaged if extra care is not
taken when cleaning.
STEP 2：If there is a screen or louvers on the exterior vent hood, they will
need to be removed during cleaning. If there is a damper, it will need to be
either taped or clipped in the open position until the cleaning is completed.
STEP 3：Be sure your dryer is turned off and unplugged. Pull the dryer out
to allow you access to the venting. Be especially careful if you have a gas
dryer.
