NOTE:

The instaHation instructions

are

similar

for

both

the

R71

unit

and

the

R72THKD

double

bay

unit.

A.

LOCATION

REQUIREMENTS

1.

To

ensure

optimum

performance

the

top

of

all units

MUST

HAVE

A MINIMUM

12"

CLEARANCE

ABOVE

THE

UNIT.

The

12"

overhead

clearance

is

also necessary

to

access

the

unitshould servicing

be

required.

(This

is

required for

the

panel

to

swing up).

THE

MINIMUM

FINISHED

FLOOR

TO

CEILING

HEIGHT

REQUIRED

FOR

PROPER

OPERATION

OF

THE

RETHERMALIZATION

REFRIGERATORS

IS

96".

2.

The

normal

temperature

of

the

room

where

the

rethermalization refrigerators

are

placed

must

not

exceed

90°F

(32.2°C) for

the

units

to

operate

properly.

B.

MOVING

THE

UNIT

THROUGH

DOORWAYS

The

doors hinges and top fascia should be·removed if location doorways are 34' (86.4cm) or narrower.

C.

REMOVAL

OF

DOORS,

HARDWARE

&

TOP

FASCIA

CAUTION

1.

Each

door

weighs approximately

72

lbs, (32.7 kg). Utmost

care

should

be

taken

whenever

the

door

is

lifted

off

its

hinges.

ATTENTION:

lfmore

than

one

unit

is

being

moved,

care

should

be

taken

when

doors

are

re-installed.

DOORS

MUST

BE

RETURNED

TO

THE

SAME

THEY

WERE

REMOVED

FROM.

2.

The

Removal

of

the

hinges

from

the

cabinet body

is

not

recommended. If it

becomes

necessary

to

remove

the

hinges,

mark

hinge

location

prior

to

removal

from

the

cabinet

to

ensure

proper

door

re-alignment.

4.

Removal

of

If it

is

necessary

to

remove

the

top

fascia,

disconnect

polarized

wire

connectors

from

the

back

of

the

MAGIC

TOUCH

CONTROLLER

before

removing

the

front lift

panel.

Remove

the

stainless steel fascia from

the

NOTE:

When

reconnecting

the

Magic

Touch Controller, be

sure

that

the

is

in

the

"A"

side,

not

the

"D"

side.

To

check

that

the

connections

are

correct,

press

the

view

button

3 times. If80 volts

is

displayed,

check

connections

again.

D.

SETTING

THE

UNIT

IN

PLACE

1.

ATTENTION:

The unitshould remain

on

its

skid during

movement

to

the

point

of

installation

to

prevent

damage

to

bottom

of

unit.

2.

CAUTION:

The single unitweighs 693 lbs. (3l4.34kg.)and

the

double

unit

weighs l019 lbs.

(462.kg.)

Extreme

Care

must

be

taken wheneverthe unit

is

moved

ortilted

to

remove the

skid.

3.

The

unit

rests

on

the

skid

and

is

not

secured by

bolts.

The

removal

from

the

skid requires

several

people

to

slowly slide

the

unit

off

the

skid. Avoid

tilting

the

unit

when

removing

if

from

the

skid.

CAUTION:

If

if

was

necessary

to

tilt

the

unit

during

installation,

if

must

not be

plugged

in

for

a period of

24

hours

after being

set

in

place.

E.

LEVELING

1.

Units must

be

level within l/8" (3.18mm)

to

ensure

proper

door

closure. Level installation

is

critical

for

the

double

door

units. If

problems

are

encountered

when

closing

the

doors,

bottom

door

seal

is

binding,

or

door

locks

are

not

engaging

properly,

the

unit

is

most likely

not

level.

2.

If

the

unit

is

more

than

l/8" (3.18mm)

out

of

level,

the

unitshould

be

shimmed.

The

recommended

shim material

is

12"

x

12"

(30.5cm) vinyl floortile.

3.

EXAMPLE:

If

the

right

hand

end

of

the

double

door

unit

is

about

l/4"(6.35mm) low,

due

to

flooring inconsistencies, use a

pry

bar

to

lift

the

low

end,

then

slide a full tile

under

that

end

as

far

as possible. If necessary,

take

a

second

tile

to

push

the

piece

as

far

under

the

unit as

possible.

Cut

off

any

tile

extending

outside

the

cabinet

body.

Add

a

second

layer

and

a

third, if necessary, until

the

unit

is

level. Be sure

to

trim

off

any

tile

projecting

out

from

the

sides

of

the

unit.

The

obiective

is

to

supportthe entire

bottom

of

the

refrigerator

so

that

the

unitfloorwill

not

sag with

use.

F.

RAMP

INSTALLATION

A stainless steel

ramp

is

shipped with

the

units.

The

front

edge

of

the

refrigerator interiorfloor

has stainless steel shoulder bolts

to

receive

and

secure the entry ramp. Simply position

the

slots

on

the

ramp

over

the

shoulder bolts

and

lower

the

ramp into position.

This

ramp

can

be

easily

removed

for cleaning

by

reversing

the

installation steps.
