that

indicated

on the

Infiltration ofany other type ofrefrigerant orair into the unit

may adversely affect the refrigerant cycle and may cause

the pipes to burst or explode.

When

installing

the

unit

in asmall

room,

exercise cau-

tion

and take measures against leaked

refrigerant

reaching

the

limiting

concentration.

Consult your dealer with any questions regarding limiting

concentrations and for precautionary measures before in-

stalling the unit. Leaked refrigerant gas exceeding the lim-

iting concentration causes oxygen deficiency.

Consult

your

dealer

ponents. Before inspecting the inside

the control box,

tum offthe power, keep the unit

off

for at least 10 minutes,

and confirm that the voltage between FT-P and FT-N on

INV Board has dropped to DC20V

less. (It takes about

10minutes to discharge electricityafterthe powersupply is

turned off.)

Precautions for handling units for use with R410A

Lt:,.

CAUTION

not

use

the

existing

refrigerant

piping.

-A large amount

chlorine thatis contained

the residual

refrigerant and refrigerator oil

the existing piping may

cause the refrigerator oil

the new unit to deteriorate.

tR410A is ahigh-pressure refrigerant and

can

cause the

existing pipes to burst.

Use

refrigerant

pipes made

phosphorus

deoxidized

copper.

Keep

the

inner

and

outer

surfaces

the

pipes

clean

and

free

such

contaminants

sulfur,

oxides,

dust,

dirt,

shaving

particles, oil,

and

water.

These types

contaminants inside the refrigerant pipes

may cause the refrigerant oil to deteriorate.

Store

the

pipes

installed

indoors,

and keep

both

ends

the

pipes

sealed

until

immediately

before

braz-

ing. (Keep

elbows

and

other

joints

wrapped

plastic.)

Infiltration of dust, dirt, orwater into the refrigerant system

may cause the refrigerating machine oil to deteriorate or

cause the unit to malfunction.

Use a

small

amount

ester

oil,

ether

all,

alkylben-

zene

coat

flares

and flanges.

Infiltration

alarge amount

mineral oil may cause the re-

frigerating machine oil

deteriorate.

Charge

liquid

refrigerant

(as

opposed

gaseous

re-

frigerant)

into

the

system.

Ifgaseous refrigerant

charged into the system, the com-

position of the refrigerant

the cylinder will change and

may result

performance loss.

HWE0803A iii

Use avacuum

pump

with a

reverse-flow

check valve.

Ifavacuum pump that is not equipped with areverse-flow

check valve

used, the vacuum pump oil mayflow into the

refrigerant cycle and cause the refrigerating machine oil to

deteriorate.

Prepare

tools

for

exclusive

use

with

R410A. Do

not

use

the

following

tools

they

have

been

used

with

the

con-

ventional

refrigerant (gauge

manifold,

charging

hose,

gas

leakdetector,reverse-flow

check

valve,refrigerant

charge base,

vacuum

gauge, and

refrigerant

recovery

equipment.).

-If

the refrigerant or the refrigerating machine oil left

these tools are mixed

with R410A, it may cause the re-

frigerating machine oil

deteriorate.

-Infiltration ofwater may cause the refrigerating machine

oil to deteriorate.

-Gas leak detectors for conventional refrigerants will not

detect an R410A leak because R410A is free ofchlorine.

not

use acharging cylinder.

If acharging cylinder

used, the composition of the refrig-

erant will change, and the unit may experience power loss.

Exercise

special care when

handling

the

tools

for

use

with

R410A.

Infiltration of dust, dirt, or water into the refrigerant system

may cause the refrigerating machine oil to deteriorate.

Only

use

refrigerant R410A.

The use

other types ofrefrigerant that contain chlorine

(Le. R22) may cause the refrigerating machine oil to deteri-

orate.
