1 PRECAUTIONS FOR DEVICES THAT USE R407C REFRIGERANT

Caution

Use ester oil, ether oil or alkylbenzene (small

amount) as the refrigerator oil to coat flares and

flange connections.

•The refrigerator oil will degrade if it is mixed with a large amount of mineral oil.

Use liquid refrigerant to seal the system.

•If gas refrigerant is used to seal the system, the composition of the refrigerant in the cylinder will change and performance may drop.

Do not use a refrigerant other than R407C.

•If another refrigerant (R22, etc.) is used, the chlorine in the refrigerant may cause the refrigerator oil to deteriorate.

Use a vacuum pump with a reverse flow check valve.

•The vacuum pump oil may flow back into the refrigerant cycle and cause the refrigerator oil to deteriorate.

Do not use the following tools that have been used with conventional refrigerants.

(Gauge manifold, charge hose, gas leak detector, reverse flow check valve, refrigerant charge base, vacuum gauge, refrigerant recovery equipment)

•If the conventional refrigerant and refrigerator oil are mixed in the R407C, the refrigerant may deteriorated.

•If water is mixed in the R407C, the refrigerator oil may deteriorate.

•Since R407C does not contain any chlorine, gas leak detectors for conventional refrigerants will not react to it.

Do not use a charging cylinder.

•Using a charging cylinder may cause the refrigerant to deteriorate.

Be especially careful when managing the tools.

•If dust, dirt, or water gets in the refrigerant cycle, the refrigerant may deteriorate.

If the refrigerant leaks, recover the refrigerant in the refrigerant cycle, then recharge the cycle with the specified amount of the liquid refrigerant indicated on the air conditioner.

•Since R407C is a nonazeotropic refrigerant, if additionally charged when the refrigerant leaked, the composition of the refrigerant in the refrigerant cycle will change and result in a drop in performance or abnormal stopping.

[1] Necessary Apparatus and Materials and Notes on Their Handling

The following tools should be marked as dedicated tools for R407C.

<<Comparison of apparatus and materials used for R407C and for R22>>

Apparatus Used	Use		R22	R407C
Gauge manifold	Evacuating, refrigerant filling		Current product
Charging hose	Operation check		Current product
Charging cylinder	Refrigerant charging		Current product	Do not use
Gas leakage detector	Gas leakage check		Current product	Shared with R134a
Refrigerant collector	Refrigerant collection		R22	For R407C use only
Refrigerant cylinder	Refrigerant filling		R22	Identification of dedi-
				cated use for R407C:
				Record refrigerant name
				and put brown belt on
				upper part of cylinder.
Vacuum pump	Vacuum drying		Current product	Can be used by attach-
				ing an adapter with a
				check valve.
Vacuum pump with a check valve			Current product
Flare tool	Flaring of pipes		Current product
Bender	Bending of pipes		Current product
Application oil	Applied to flared parts		Current product	Ester oil or Ether oil or
				Alkybenzene (Small
				amount)
Torque wrench	Tightening of flare nuts		Current product
Pipe cutter	Cutting of pipes		Current product
Welder and nitrogen cylinder	Welding of pipes		Current product
Refrigerant charging meter	Refrigerant charging		Current product
Vacuum gauge	Checking the vacuum degree		Current product
Symbols: To be used for R407C only.		Can also be used for conventional refrigerants.

Tools for R407C must be handled with more care than those for conventional refrigerants. They must not come into contact with any water or dirt.

[2] Brazing

No changes from the conventional method, but special care is required so that foreign matter (ie. oxide scale, water, dirt, etc.) does not enter the refrigerant circuit.

Example: Inner state of brazed section

When non-oxide brazing was not used

When non-oxide brazing was used

Items to be strictly observed:

1.Do not conduct refrigerant piping work outdoors on a rainy day.

2.Apply non-oxide brazing.

3.Use a brazing material (BCuP-3) which requires no flux when brazing between copper pipes or between a copper pipe and copper coupling.

4.If installed refrigerant pipes are not immediately connected to the equipment, then braze and seal both ends of them.

Reasons:

1.The new refrigerant oil is 10 times more hygroscopic than the conventional oil. The probability of a machine failure if water infiltrates is higher than with conventional refrigerant oil.

2.A flux generally contains chlorine. A residual flux in the refrigerant circuit may generate sludge.

Note:

•Commercially available antioxidants may have adverse effects on the equipment due to its residue, etc. When applying non-oxide brazing, use nitrogen.

- 3 -

[3] Airtightness Test

No changes from the conventional method. Note that a refrigerant leakage detector for R22 cannot detect R407C leakage.

NO NO

Halide torch

R22 leakage detector

Items to be strictly observed:

1.Pressurize the equipment with nitrogen up to the design pressure and then judge the equipment’s airtightness, taking temperature variations into account.

2.When investigating leakage locations using a refrigerant, be sure to use R407C.

3.Ensure that R407C is in a liquid state when charging.

Reasons:

1.Use of oxygen as the pressurized gas may cause an explosion.

2.Charging with R407C gas will lead the composition of the remaining refrigerant in the cylinder to change and this

refrigerant can then not be used.

Note:

•A leakage detector for R407C is sold commercially and it should be purchased.

[4]Vacuuming

1.Vacuum pump with check valve

A vacuum pump with a check valve is required to prevent the vacuum pump oil from flowing back into the refrigerant circuit when the vacuum pump power is turned off (power failure).

It is also possible to attach a check valve to the actual vacuum pump afterwards.

2.Standard degree of vacuum for the vacuum pump

Use a pump which reaches 0.5 Torr (500 MICRON) or below after 5 minutes of operation.

In addition, be sure to use a vacuum pump that has been properly maintained and oiled using the specified oil. If the vacuum pump is not properly maintained, the degree of vacuum may be too low.

3.Required accuracy of the vacuum gauge

Use a vacuum gauge that can measure up to 5 Torr. Do not use a general gauge manifold since it cannot measure a vacuum of 5 Torr.

4.Evacuating time

•Evacuate the equipment for 1 hour after –755 mmHg (5 Torr) has been reached.

•After envacuating, leave the equipment for 1 hour and make sure the that vacuum is not lost.

5.Operating procedure when the vacuum pump is stopped

In order to prevent a backflow of the vacuum pump oil, open the relief valve on the vacuum pump side or loosen the charge hose to drawn in air before stopping operation.

The same operating procedure should be used when using a vacuum pump with a check valve.

[5] Charging of Refrigerant

R407C must be in a liquid state when charging, because it is a non-azeotropic refrigerant.

	Cylin-
Cylin-	der
der

Cylinder color identification R407C-Gray		Charged with liquid refrigerant
Valve	R410A-Pink	Valve

Liquid

Liquid

Reasons:

1.R407C is a mixture of 3 refrigerants, each with a different evaporation temperature. Therefore, if the equipment is charged with R407C gas, then the refrigerant whose evaporation temperature is closest to the outside temperature is charged first while the rest of refrigerants remain in the cylinder.

Note:

•In the case of a cylinder with a syphon, liquid R407C is charged without turning the cylinder up side down. Check the type of cylinder before charging.
