•

Before

switching

it

on,

test

the

supply

terminal

tier

(L,

N

terminals)

and

grounding

points

with

500V

megaohm

meter

and

check

if

the

resistance

is

above

1M

C2

.

It

can't

be

operated

if

it

is

below

1M

C2

.

•

Connect

it

to

the

power

supply

of

outdoor

units

to

energize

the

heating

belt

of

the

compressor.

To

are

correct.

The

drainpipe

shall

be

placed

at

the

lower

part

while

the

connection

line

placed

at

the

part.

Heat

preservation

measures

should

be

taken

such

as

winding

the

drainpipe

esp.

in

the

indoor

units

with

heating

insulating

materials.

The

drain

pipe

should

be

made

a

type

to

avoid

protruding

at

the

upper

part

and

concaving

at

the

lower

part

on

the

way.

Checkup

of

Installation

o

check

if

the

mains

voltage

is

matching

o

check

if

the

installation

place

meets

the

requirement

o

check

if

there

is

air

leakage

at

the

piping

o

check

if

there

is

too

much

noise

joints

o

check

if

the

connecting

line

is

fastened

0

check

if

the

connections

of

mains

power

o

check

if

the

connectors

for

tubing

are

heat

insulated

and

indoor

&

outdoor

units

are

correct

o

check

if

the

water

is

drained

to

the

outside

o

check

if

the

serial

numbers

of

terminals

are

0

check

if

the

indoor

units

are

positioned

matching

(Ways

of

Test

Rur)

Do

ask

the

installation

personnel

to

make

a

test

run.

Take

he

testing

procedures

according

to

the

manual

and

check

if

the

temperature

regulator

works

properly.

When

the

machine

fails

to

start

due

to

the

room

temperature,

the

following

procedures

can

be

taken

to

do

the

compulsive

running.

The

function

is

not

provided
