2.3.2 Wall-Mount Installation

The

RIU

may

be

mounted

from

any

flat

vertical

surface.

It

is

recommended

that

a

backer

board

such

as

3/4-inch

plywood

be

applied

over

the

mounting

surface

to

provide

a

secure

base

for

attaching

the

RIU.

Two

mounting

holes

are

provided

in

the

cable

management

tray

for

securing

the

RIU

to

the

mounting

surface.

In

addition,

the

mounting

brackets

may

be

removed

and

then

reinstalled

in

such

a

way

that

they

can

be

used

for

securing

the

RIU

to

the

mounting

surface.

Either

method

for

mounting

may

be

used

at

the

discretion

of

the

installer.

The

fasteners

must

be

provided

by

the

installer.

Use

the

following

procedure

to

wall-mount

the

equipment.

To

prevent

electrical

shock,

never

install

or

use

electrical

equipment

the

mounting

brackets

will

both

mounting

brackets

from
