1-2. Prevent impurities including water, dust and oxide from entering the tubing. Impurities can cause R410A

refrigerant deterioration and compressor defects. Due to the features of the refrigerant and refrigerating
machine oil, the prevention of water and other impurities becomes more important than ever.

2. Be sure to recharge the refrigerant only in liquid form.

2-1. Since R410A is a non-azeotrope, recharging the refrigerant in gas form can lower performance and cause

defects of the unit.

2-2. Since refrigerant composition changes and performance decreases when gas leaks, collect the remaining

refrigerant and recharge the required total amount of new refrigerant after fixing the leak.

3. Different tools required

3-1. Tool specifications have been changed due to the characteristics of R410A.

Some tools for R22- and R407C-type refrigerant systems cannot be used.

Item

compatible Remarks
with R410A?

Manifold gauge Yes

No

Types of refrigerant, refrigerating machine oil, and
pressure gauge are different.

Charge hose Yes No

To resist higher pressure, material must be changed.

Vacuum pump Yes Yes

Use a conventional vacuum pump if it is equipped
with a check valve. If it has no check valve,
purchase and attach a vacuum pump adapter.

Leak detector Yes No

Leak detectors for CFC and HCFC that
react to chlorine do not function because
R410A contains no chlorine. Leak detector
for HFC134a can be used for R410A.

Flaring oil Yes No

For systems that use R22, apply mineral oil (Suniso oil)
to the flare nuts on the tubing to prevent refrigerant
leakage. For machines that use R407C or R410A, apply
synthetic oil (ether oil) to the flare nuts.

Precautions for Installation Using New Refrigerant

1. Care regarding tubing

1-1. Process tubing

Material: Use C1220 phosphorous deoxidized copper specified in JIS H3300 “Copper and Copper Alloy Seam-
less Pipes and Tubes.”

Tubing size: Be sure to use the sizes indicated in the table below.

Use a tube cutter when cutting the tubing, and be sure to remove any flash. This also applies to distribution
joints (optional).

When bending tubing, use a bending radius that is 4 times the outer diameter of the tubing or larger.

* Using tools for R22 and R407C and new tools for R410A together can cause defects.

Manifold gauge

Vacuum pump

Outlet
Inlet

CAUTION

Use sufficient care in handling the tubing. Seal the tubing ends with
caps or tape to prevent dirt, moisture, or other foreign substances
from entering. These substances can result in system malfunction.
