Enclosure Alterations

Hoffman Enclosures Inc.

2100 Hoffman Way

Anoka, MN 55303−1745

(763) 422−2211

Hoffman cannot assure the safety or effectiveness of any alterations or
additions not made by Hoffman Enclosures Inc. However, the following
information may be helpful. These instructions do not eliminate the need
to consult with equipment manufacturers and to observe all regulatory agency procedures and safe
practices to assure the proper electrical and mechanical function of Hoffman products in each
particular application.

1. REPAINTING

See “Instructions for Repainting Hoffman
Standard Paint Finishes”, part number

23155002.

4. PANEL INSTALLATION

When the interior panel is being installed, it
may be necessary to bend one or more
mounting studs slightly to permit the panel to fit
in place. Simply position the panel on the studs

2. MOUNTING INSTRUCTIONS

a. Wall mounted enclosures have either an

internal mounting means or external
mounting feet. Proper fasteners must be
used in all mounting holes to secure the
enclosure to the wall.

b. Floor mounted enclosures have floor

stands (legs) which include mounting
plates. Proper fasteners must be used in
all mounting holes to securely anchor the
enclosure to the floor.

3. DOOR CLOSING ADJUSTMENTS

a. Single door (wall mounted)

If the surface on which the enclosure is
mounted is not flat, the door may not open
and close properly. Also, if heavy
equipment is mounted on a large door, the
door may sag slightly. If the top of the door
strikes the lip which extends around the
body opening, place metal shims behind
the mounting foot which is located at the
bottom of the enclosure and closest to the
door hinge. Place the shims between the
mounting foot and the wall or mounting
surface. Be sure all mounting screws are
tightened securely.

b. Two door (floor mounted)

The overlapping doors are factory−fitted to
meet evenly at the top and bottom. If the
floor under the enclosure is not level, the
doors will not close evenly. In this case,
place metal shims under the corners of the
enclosure. The enclosure should be
bolted in place with the doors closed to
prevent tipping when installing shims.
Shims under the right front corner will raise
the right door. Shims under the left front

that line up properly and pry the other studs
into position with a suitable screwdriver
inserted through the panel holes.

5. REMOVING HINGE PINS FROM
CONTINUOUS HINGES

This can be a difficult operation requiring one or
more people. This procedure is best
accomplished by using a small diameter punch
to drive the hinge pin toward the bottom of the
enclosure. Lay the wall−mounted and
floor−mounted or free−standing enclosure on
its back side (see note 7 below). When the
hinge pin protrudes about two inches below the
bottom hinge barrel, bend the end of the pin
180° so it is shaped like the letter “J”. Use an
electric or air powered vibrating hammer fitted
with a tool which has a hole in the end to fit
over the hinge pin, and drive the hinge pin out
while opening and closing the door. To install
the hinge pin, straighten the pin and drive it in
with the vibrating hammer while opening and
closing the door. Most hinge pins have one
end chamfered, so be sure to start the
chamfered end first when installing the pin.

6. PRINT POCKET

The print pocket on the door can be inverted or
removed entirely.

7. LIFTING ENCLOSURES BY EYEBOLTS

To lift an enclosure which has eyebolts or
mounting feet, be sure to use all the eyebolts
and top mounting feet provided. Arrange the
chains and cables with spreader bars so you
are lifting straight up on the eyebolts or top
mounting feet.

corner will raise the left door. It is
important that the doors meet evenly to
insure a proper seal against liquids and
dust. Be sure all mounting bolts are
tightened securely.
