Ÿ Mark the positions of holes of 2 corners of the inverter’s
bracket by marker pen.
Ÿ Drill holes with driller and make sure the holes are deep
enough(at least 40mm) to support the inverter.
Step1: Drill holes on the wall
Step2: Mounting the inverter
Ÿ Make sure the inveter is well fixed.
Ÿ Insert the expansion tubes into the holes and lighten
them. Then install the inverter by screwing the screws.
