Refrigerant

INFORMATION FOR THE AIR CONDITIONER WITH R410A REFRIGERANT

•This room air conditioner adopts an HFC refrigerant (R410A) which never destroys the ozone layer.

•Pay particular attention to the following points, though the basic installation procedure is same as that for R22 conditioners. 1 As R410A has working pressure approximate 1.6 times as high as that of R22, some special tools and piping parts/

materials are required. Refer to the table below.

2 Take sufficient care not to allow water and other contaminations to enter the R410A refrigerant during storage and installation, since it is more susceptible to contaminations than R22.

3 For refrigerant piping, use clean, pressure-proof parts/materials specifically designed for R410A. (Refer to 2. Refrigerant piping.)

4 Composition change may occur in R410A since it is a mixed refrigerant. When charging, charge liquid refrigerant to prevent composition change.

1. Tools dedicated for the air conditioner with R410A refrigerant

The following tools are required for R410A refrigerant. Some R22 tools can be substituted for R410A tools.

The diameter of the service port on the stop valve in outdoor unit has been changed to prevent any other refrigerant being charged into the unit. Cap size has been changed from 7/16 UNF with 20 threads to 1/2 UNF with 20 threads.

	R410A tools	Can R22 tools be used?	Description
			R410A has high pressures beyond the measurement range of existing
	Gauge manifold	No	gauges. Port diameters have been changed to prevent any other refrigerant
			from being charged into the unit.
	Charge hose	No	Hose material and cap size have been changed to improve the pressure
			resistance.
	Gas leak detector	No	Dedicated for HFC refrigerant.
	Torque wrench	Yes	6.35 mm and 9.52 mm
		No	12.7 mm and 15.88 mm
	Flare tool	Yes	Clamp bar hole has been enlarged to reinforce the spring strength in the tool.
	Flare gauge	New	Provided for flaring work (to be used with R22 flare tool).
	Vacuum pump	New	Provided to prevent the back flow of oil. This adapter enables you to use
	adapter		vacuum pumps.
	Electronic scale for	New	It is difficult to measure R410A with a charging cylinder because the
	refrigerant charging		refrigerant bubbles due to high pressure and high-speed vaporization

No : Not Substitutable for R410A Yes : Substitutable for R410A

2. Refrigerant piping

1Specifications

Use the refrigerant pipes that meet the following specifications.

	Pipe	Outside diameter	Wall thickness	Insulation material
		mm	mm
	For liquid	6.35	0.8
				Heat resisting foam plastic
		9.52	0.8
		9.52	0.8	Specific gravity 0.045 Thickness
	For gas			8 mm
		12.7	0.8

15.881.0

•Use a copper pipe or a copper-alloy seamless pipe with a thickness of 0.8 mm. Never use any pipe with a thickness less than 0.8mm, as the pressure resistance is insufficient.

2Flaring work and flare nut

Flaring work for R410A pipe differs from that for R22 pipe.

For details of flaring work, refer to Installation manual “FLARING WORK”.

Pipe diameter (mm)	Dimension of flare nut (mm)
	R410A	R22
6.35	17	17
9.52	22	22
12.7	26	24
15.88	29	27

3. Refrigerant oil

Apply the special refrigeration oil (accessories: packed with indoor unit) to the flare and the union seat surfaces.

4.Air purge

•Do not discharge the refrigerant into the atmosphere.

Take care not to discharge refrigerant into the atmosphere during installation, reinstallation, or repairs to the refrigerant circuit.

•Use the vacuum pump for air purging for the purpose of environmental protection.

5.Additional charge

For additional charging, charge the refrigerant from liquid phase of the gas cylinder.

If the refrigerant is charged from the gas phase, composition change may occur in the refrigerant inside the cylinder and the outdoor unit. In this case, ability of the refrigerating cycle decreases or normal operation can be impossible. However, charging the liquid refrigerant all at once may cause the compressor to be locked. Thus, charge the refrigerant slowly.
