1.) Open the door using the key provided.
Next lift off the front door by sliding it
up and off the pins of the hinges.
Put it aside.
2.) Mount base with hinge pins along left side
by using mounting holes (4 are available).

anywhere around the bottom or right side. Do
not place an access hole on the hinge side of the

a chassis punch to match the required fitting size.
