3 SAFETY PRECAUTION

3-2. CAUTIONS RELATED TO NEW REFRIGERANT

Cautions for units utilizing refrigerant R410A

Use new refrigerant pipes.

Make sure that the inside and outside of refrige-

rant piping is clean and it has no contamination

such as sulfur hazardous for use, oxides, dirt,

shaving particles, etc.

In addition, use pipes with specified thickness.

Store the piping to be used indoors during

installation and both ends of the piping sealed

until just before brazing. (Leave elbow joints, etc.

in their packaging.)

In case of using the existing pipes for R22, be careful with

the followings.

· Be sure to clean the pipes and make sure that the insides

of the pipes are clean.

· Change flare nut to the one provided with this product.

Use a newly flared pipe.

· Avoid using thin pipes.

Charge refrigerant from liquid phase of gas

cylinder.

If the refrigerant is charged from gas phase, composition

change may occur in refrigerant and the efficiency will be

lowered.

Do not use refrigerant other than R410A.

If other refrigerant (R22 etc.) is used, chlorine in refrige-

rant can cause deterioration of refrigerant oil etc.

Use a vacuum pump with a reverse flow check

valve.

Vacuum pump oil may flow back into refrigerant cycle and

that can cause deterioration of refrigerant oil etc.

Use the following tools specifically designed for

use with R410A refrigerant.

The following tools are necessary to use R410A refrigerant.

Handle tools with care.

If dirt, dust or moisture enter into refrigerant cycle, that can

cause deterioration of refrigerant oil or malfunction of com-

pressor.

Do not use a charging cylinder.

If a charging cylinder is used, the composition of refrigera-

nt will change and the efficiency will be lowered.

Tools for R410A

Contamination inside refrigerant piping can cause deterio-

ration of refrigerant oil etc.

If dirt, dust or moisture enter into refrigerant cycle, that can

cause deterioration of refrigerant oil or malfunction of com-

pressor.

If large amount of mineral oil enter, that can cause deterio-

ration of refrigerant oil etc.

The refrigerant oil applied to flare and flange

connections must be ester oil, ether oil or

alkylbenzene oil in a small amount.

Ventilate the room if refrigerant leaks during

operation. If refrigerant comes into contact with

a flame, poisonous gases will be released.

Use the specified refrigerant only.

Never use any refrigerant other than that specified.

Doing so may cause a burst, an explosion, or fire when the

unit is being used, serviced, or disposed of.

Correct refrigerant is specified in the manuals and on the

spec labels provided with our products.

We will not be held responsible for mechanical failure,

system malfunction, unit breakdown or accidents caused

by failure to follow the instructions.

3-1. ALWAYS OBSERVE FOR SAFETY

Before obtaining access to terminal, all supply

circuits must disconnected.

Unit

[3] Service tools

Use the below service tools as exclusive tools for R410A refrigerant.

Cautions for refrigerant piping work

New refrigerant R410A is adopted for replacement inverter series. Although the refrigerant piping work for R410A is same

as for R22, exclusive tools are necessary so as not to mix with different kind of refrigerant. Furthermore as the working

pressure of R410A is 1.6 times higher than that of R22, their sizes of flared sections and flare nuts are different.

1Thickness of pipes

Because the working pressure of R410A is higher compared to R22, be sure to use refrigerant piping with thickness

shown below. (Never use pipes of 0.7mm or below.)

8Refrigerant recovery equipment —

[1] Cautions for service

(1) Perform service after collecting the refrigerant left in unit completely.

(2) Do not release refrigerant in the air.

(3) After completing service, charge the cycle with specified amount of refrigerant.

(4) When performing service, install a filter drier simultaneously.

Be sure to use a filter drier for new refrigerant.

[2] Additional refrigerant charge

When charging directly from cylinder

· Check that cylinder for R410A on the market is syphon type.

· Charging should be performed with the cylinder of syphon stood vertically. (Refrigerant is charged from liquid phase.)

2Dimensions of flare cutting and flare nut

The component molecules in HFC refrigerant are smaller compared to conventional refrigerants. In addition to that,

R410A is a refrigerant, which has higher risk of leakage because of its working pressure higher than that of other refriger-

ants. Therefore, to enhance airtightness and intensity, flare cutting dimension of copper pipe for R410A has been speci-

fied separately from the dimensions for other refrigerants as shown below. The dimension B of flare nut for R410A also

has partly been changed to increase intensity as shown below. Set copper pipe correctly referring to copper pipe flaring

dimensions for R410A below. For 1/2” and 5/8”, the dimension B changes.

Use torque wrench corresponding to each dimension.

CHARGELESS SYSTEM

PRE-CHARGED REFRIGERANT IS SUPPLIED FOR PIPING LENGTH AT SHIPMENT. (Max.30m)

The refrigerant circuit with LEV (Linear Expansion Valve) and accumulator always control the optimal refrigerant level

regardless of the length (30m max. and 5m min.) of piping. The additional refrigerant charging work during installation often

causes problems. Heretofore it is completely eliminated. This unique system improves the quality and reliability of the work

done. It also helps to speed up the installation time.
