Mounting

CAUTION

This equipment is designed for operation in a

horizontal position only, with mounting brackets down.

Do not operate in any other manner.

The attenuator may stand free, may be secured to a bench,

or any convenient flat surface. The front and rear face

plates are made of heavier gauge material bent outward 90°

at the bottom to form mounting flanges. At each corner of

these flanges is a 3/8 inch hole for use with suitable fasten-

ers up to 3/8 inch. The holes are arranged in a 20-23/32 inch

x 4-1/2 inch rectangle (526.3 x 114.3mm). The front and rear

face plates of the attenuator are also bent over on the top to

form convenient carrying handles. The following instruc-

tions are for mounting the unit to a suitable surface.

1. Place the unit on a flat surface.

2. Insert the fasteners, up to 3/8 inch,

through the bench and the holes.

3. Secure the bolts with nuts and lock

washers.

Vent Plug

WARNING

The vent plug must be used at all times when the unit

is in operation or cooling. Failure to do this could

result in damage to the equipment and endanger the

operator’s safety. Be sure to check the plug.

Before placing the attenuator into service, the solid shipping

plug must be removed and replaced by the spring loaded

vent plug. The vent hole for these plugs is located at the top

left hand side near the front. The two plugs are linked to-

gether by a short length of bead chain. The shipping plug

should be placed back in the vent hole whenever the

attenuator is to be shipped. Be careful not to lose the O-

Ring seal. Refer to figures 2 and 3 for plug identification.
