Provide

Clearances

The

required

minimum

service

clearances

are

shown

in

5 and

6.

Adequate

ventilation

and

outdoor

air

must

be

provided.

The

outdoor

fan

draws

air

through

the

outdoor

coil

and

discharges

it

through

the

top

fan

grille.

Be

sure

that

the

fan

discharge

does not

recirculate

to

the

outdoor

coil. Do

not

locate

the

unit

in

either

a

corner

or

under

an

overhead

obstruction.

The

minimum

clearance

under

a

partial

overhang

(such

as

a

normal

house

overhang)

is

48

in.

above

the unit top. The maximum

horizontal

extension

of

a

partial

overhang

must

not

exceed

48

in.

(1219 mm).

IMPORTANT:

Do

not

restrict

outdoor

airflow.

An

air

restriction

at

either

the

outdoor-air

inlet

or

the

fan

discharge

may

be

detrimental

to

compressor

life.

Do

not

place

the

unit

where

water,

ice,

or

snow

from

an

overhang

or

roof

will

damage

or

flood

the

unit.

Do

not

install

the

unit

on

carpeting

or

other

combustible

materials.

Slab-mounted

units

should

be at

least

4

in.

(102

mm)

above

the

highest

expected

water

and

runoff

levels.

Do

not

use

unit

if

it

has been

under

water.

Rig

and

Place

Unit

Rigging

and

handling

of

this

equipment

can

be

hazardous

for

many

reasons

due

to

the

installation

location

(roofs,

elevated

structures,

etc.).

Only

trained,

qualified

crane

operators

and

ground

support

staff

should

handle

and

install

this

equipment.

When

working

with

this

equipment,

observe

precautions

in

the

literature,

on

tags,

stickers,

and

labels

attached

to

the

equipment,

and

any

other

safety

precautions

that

might

apply.

Training

for

operators

of

the

lifting

equipment

should

include,

but

not

be

limited

to,

the

following:

1.

Application

of

the

lifter

to

the

load,

and

adjustment

of

the

lifts

to

adapt

to

various

sizes

or

kinds

of

loads.

2.

Instruction

in

any

special

operation

or

precaution.

3.

Condition

of the

load

as

it

relates

to

operation

of

the

lifting

kit,

such

as

balance,

temperature,

etc.

Follow

all

applicable

safety

codes.

Wear

safety

shoes

and

work

gloves.
