INSTALLING

REFRIGERANT

LINES

The

following

steps

are

to

be

considered

when

installing

the

refrigerant lines:

1. Determine

the

most

practical

way

to

run

the

lines.

2. Consider types

of

bends

to

be

made

and

space limita-

tions.

NOTE:

Large

diameter

tubing

sizes

will

be

difficult

to

bend

once

it

has

been

shaped.

3. Determine

the

best

starting

point for

routing

the

refrig-

erant

tubing

--INSIDE OR OUTSIDE

THE

STRUC-

TURE.

4.

Provide a

pull

through

hole of sufficient size

to

allow

both

liquid

and

gas lines

to

clear.

The

location of

this

hole

(if

practical) should

be

just

above

the

wall

plate

which

is

resting

on

the

foundation.

5. Be

sure

the

roll

of

tubing

is

of sufficient length.

6.

Uncoil

the

tubing-

do

not

kink

or dent.

7. Route

the

tubing

making

all required bends

and

prop-

erly secure

the

tubing

before malting final connections.

NOTE:

These

lines

must

be

isolated.

from

the

struc-

ture

and

the

holes

must

be

sealed

weather

tight

after

installation.

F.

FIELD

FABRICATED

INTERCONNECTING

LINES

The

BRAZING

TO

EVAPORATOR

SECTION

IMPORTANT:

Do

not

unseal refrigerant

tubing

until

ready

to

cut

and

fit

refrigerant

lines.

There

is

only a holding charge

of

dry

Nitrogen

in

the

indoor

coil, therefore no loss

of

operating refrigerant charge occurs

when

the

sealing plugs

are

removed.

NOTE:

bulb

MUST

be

protected

(wrapped

with

wet

rag)

or

removed,

while

brazing

the

tubing.

Over-

heating

of

the

sensing

bulb

will

affect

the

functional

characteristics

and

performance

of

the

coil.

NOTE:

Torque
