Precautions for Handling Units for Use with R410A

△Caution
Do not use the existing refrigerant piping ·The old refrigerant and refrigerator oil in the existing piping contain a large amount of chlorine, which will cause the refrigerator oil in the new unit to deteriorate. ·R410A is a high-pressure refrigerant, and the use of the existing piping may result in bursting.	Use a vacuum pump with a reverse-flow check valve. ·If other types of valves are used, the vacuum pump oil will flow back into the refrigerant cycle and cause the refrigerator oil to deteriorate. Do not use the following tools that have been used with the conventional refrigerants. Prepare tools that are for exclusive use with R410A. (Gauge manifold, charging hose, gas leak detector, reverse-flow check valve, refrigerant charge base, vacuum gauge, and refrigerant recovery equipment.) ·If refrigerant and/or refrigerant oil left on these tools are mixed in with R410, or if water is mixed with R410A, it will cause the refrigerant to deteriorate. ·Since R410A does not contain chlorine, gas-leak detectors for conventional refrigerators will not work.
Keep the inner and outer surfaces of the pipes clean and free of contaminants such as sulfur, oxides, dust/dirt shaving particles,oils,and moisture. ·Contaminants inside the refrigerant piping will cause the refrigerant oil to deteriorate.

△Caution

Store the piping to be used during installation indoors, and keep both ends of the piping sealed until immediately before brazing.(keep elbows and other joints wrapped in plastic.) •If dust, dirt, or water enters the refrigerant cycle, it may cause the oil in the unit to deteriorate or may cause the compressor to malfunction. Use a small amount of ester oil, ether oil, or alkylbenzene to coat flares and flange connections. •A large amount of mineral oil will cause the refrigerating machine oil to deteriorate. Use liquid refrigerant to charge the system. •Charge the unit with gas refrigerant will cause the refrigerant in the cylinder to change its composition and will lead to a drop in performance

Do not use a charging cylinder. •The use of charging cylinder will change the composition of the refrigerant and lead to power loss. Exercise special care when handling the tools. •An introduction of foreign objects such as dust, dirt or water into the refrigerant cycle will cause the refrigerating machine oil to deteriorate. Only use R410A refrigerant. •The use of refrigerants containing chlorine(i.e. R22) will cause the refrigerant to deteriorate.

Before Installing the Unit

△Caution

Do not install the unit in a place where there is a possibility of flammable gas leak. ·Leaked gas accumulated around the unit may start a fire. Do not use the unit to preserve food, animals, plants, artifacts, or for other special purposes. ·The unit is not designed to provide adequate conditions to preserve the quality of these items. Do not use the unit in an unusual environment ·The use of the unit in the presence of a large amount of oil, steam, acid, alkaline solvents or special types of sprays may lead to a remarkable drop in performance and/or malfunction and presents a risk of electric shock, smoke, or fire. ·The presence of organic solvents, corroded gas (such as ammonia,sulfur compounds,and acid may cause gas or water leak.)

When installing the unit in a hospital, take necessary measures against noise. ·High-frequency medical equipment may interfere with the normal operation of the air conditioning unit or the air conditioning unit may interfere with the normal operation of the medical equipment Do not place the unit on or over things that may not get wet. ·When humidity level exceeds 80% or when the drainage system is clogged, indoor units may drip water. ·Installation of a centralized drainage system for the outdoor unit may also need to be considered to prevent water drips from the outdoor units.

Before Installing (Relocating) the Unit or Performing Electric Work

△Caution

Ground the unit. ·Do not connect the grounding on the unit to gas pipes, water pipes, lightning rods, or the grounding terminals of telephones. Improper grounding presents a risk of electric shock, smoke, fire, or the noise caused by improper grounding may cause the unit to malfunction. Make sure the wires are not subject to tension. ·If the wires are too taut, they may break or generate heat and/or smoke and cause fire. Install a breaker for current leakage at the power source to avoid the risk of electric shock. ·Without a breaker for current leakage, there is a risk of electric shock, smoke or fire. Use breakers and fuses (electrical current breaker, remote switch<switch+Type-B fuse>, molded case circuit breaker) with a proper current capacity. ·The use of large-capacity fuses, steel wire, or copper wire may damage the unit or cause smoke or fire.

Do not spray water on the air conditioners or immerse the air conditioners in water. ·Water on the unit presents a risk of electric shock. Periodically check the platform on which is placed for damage to prevent the unit from falling. ·If the unit is left on a damaged plarform, it may topple over, causing injury. When installing draining pipes, follow the instructions in the manual, and make sure that they properly drain water so as to avoid dew condensation. ·If not installed properly, they may cause water leaks and damage the furnishings. Properly dispose of the packing materials. ·Things such as nails may be included in the package. Disposition of them properly to prevent injury. ·Plastic bags present a choking hazard to children. Tear up the plastic bags before disposing of them to prevent accidents.

Before the Test Run

△Caution
Do not operate switches with wet hands to avoid electric.	Do not turn off the power immediately after stopping the unit. •Allow for at least five minutes before turning off the unit, otherwise the unit may leak water or experience other problems.
Do not touch the refrigerant pipes with bare hands during and immediately after operation. •Depending on the state of the refrigerant in the system, certain parts of the unit such as the pipes and compressor may become very cold or hot and may subject the person to frost bites or burning.
Do not operated the unit without panels and safety guards in their proper places. •They are there to keep the users from injury from accidentally touching rotating, high-tempreture or high-voltage parts.	Do not operate the unit without air filters. •Dust particles in the air may clog the system and cause malfunction.

Items to Be Checked

(1). Verify the type of refrigerant used by the unit to be serviced. Refrigerant Type: R410A
(2). Check the symptom exhibited by the unit to be serviced. Look in this service handbook for symptoms relating to the refrigerant cycle.
(3). Be sure to carefully read the safety precautions at the beginning of this document.
(4). If there is a gas leak or if the remaining refrigerant is exposed to an open flame, a noxious gas hydrofluoric acid may form. Keep workplace well ventilated.

CAUTION

• Install new pipes immediately after removing old ones to keep moisture out of the refrigerant circuit.
• Chloride in some types of refrigerants such as R22 will cause the refrigerating machine oil to deteriorate.

Piping Materials

Types of Copper Pipes (Reference)

Maximum Operation Pressure	Applicable Refrigerants
3.4MPa	R22, R407C
4.15MPa	R410A

• Use pipes that meet the local standards.

Piping Materials/Radial Thickness

Use pipes made of phosphorus deoxidized copper.

Since the operation pressure of the units that use R410A is higher than that of the units for use with R22, use pipes with at least the radial thickness specified in the chart below. (Pipes with a radial thickness of 0.7mm or less may not be used.)

Size(mm)	Size(inch)	Radial Thickness(mm)	Type
Φ 6.35	1/4"	0.8t	Type-O pipes
Φ 9.52	3/8"	0.8t
Φ 12.7	1/2"	0.8t
Φ 15.88	5/8"	1.0t
Φ 19.05	3/4"	1.0t	Type-1/2H or Hpipes

• Although it was possible to use type-O for pipes with a size of up to 19.05(3/4^) with conventional refrigerants, use type-1/2H pipes for units that use R410A.(Type-O pipes may be used if the pipe size is 19.05 and the radial thickness is 1.2t. )
• The table shows the standards in Japan. Using this table as a reference, choose pipes that meet the local standards.

Flare Machining (type-O and OL only)

The flare machining dimensions for units that use R410A is larger than those for units that use R22 in order to increase air tightness.

Flare Machining Dimension(mm)

External dimension of pipes	Size	Dimension A
		R410A	R22
Φ6.35	1/4"	9.1	9.0
Φ9.52	3/8"	13.2	13.0
Φ12.7	1/2"	16.6	16.2
Φ15.88	5/8"	19.7	19.4
Φ19.05	3/4"	24.0	23.3

If a clutch type flare tool is used to machine flares on units that use R410A, make the protruding part of the pipe between 1.0 and 1.5mm . Copper pipe gauge for adjusting the length of pipe protrusion is useful.

Flare Nut

Type-2 flare nuts instead of type-1 nuts are used to increase the strength. The size of some of the flare nuts have also been changed.

Flare nut dimension(mm)

External dimension of pipes	Size	Dimension B
		R410A(Type2)	R22(Type1)
Φ6.35	1/4"	17.0	17.0
Φ9.52	3/8"	22.0	22.0
Φ12.7	1/2"	26.0	24.0
Φ15.88	5/8"	29.0	27.0
Φ19.05	3/4"	36.0	36.0

Dimension B

• The table shows the standards in Japan. Using this table as a reference, choose pipes that meet the local standards.

Air Tightness Test

No changes from the conventional method. Note that a refrigerant leakage detector for R22 or R407C cannot detect R410A leakage.

Halide torch

R22 or R407C leakage detector

Items to be strictly observed :

1. Pressurize the equipment with nitrogen up to the design pressure and then judge the equipment's air tightness, taking temperature variations into account.
2. When investigating leakage locations using a refrigerant, be sure to use R410A.
3. Ensure that R410A is in a liquid state when charging.

Reasons:

1. Use of oxygen as the pressurized gas may cause an explosion.
2. Charging with R410A gas will lead the composition of the remaining refrigerant in the cylinder to change and then this refrigerant can not be used.

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 65Pa 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 650Pa . Do not use a general gauge manifold since it cannot measure a vacuum of 650Pa .

4.Evacuating time

Evacuate the equipment for 1 hour after 650Pa has been reached.

After evacuating, 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 draw in air before stopping operation. The same operating procedure should be used when using a vacuum pump with a check valve.

Charging Refrigerant

R410A must be in a liquid state when charging.

Reasons:

R410A is a pseudo-azeotropic refrigerant (boiling point R32 = -52^ , R125 = -49^ ) and can roughly be handled in the same way as R22; however, be sure to fill the refrigerant from the liquid side, for doing so from the gas side will somewhat change the composition of the refrigerant in the cylinder.

Note

• In the case of a cylinder with a syphon, liquid R410A is charged without turning the cylinder up side down. Check the type of cylinder before charging.

Remedies to be taken in case of a refrigerant leak

When refrigerant leaks, additional refrigerant may be charged. (Add the refrigerant from the liquid side)

Characteristics of the Conventional and the New Refrigerants

• Because R410A is a simulated azeotropic refrigerant, it can be handled in almost the same manner as a single refrigerant such as R22. However, if the refrigerant is removed in the vapor phase, the composition of the refrigerant in the cylinder will somewhat change.
• Remove the refrigerant in the liquid phase. Additional refrigerant may be added in case of a refrigerant leak.

1. Accessories

"Edging" for protection of electrical wires from an opening edge.

2. Selection of the place of installation

Select the place of installation satisfying the following conditions and, at the same time, obtain a consent from the client or user.

• Place where air circulates.
• Place free from heat radiation from other heat sources.
• Place where drain water may be discharged.
• Place where noise and hot air may not disturb the neighborhood.
• Place where there is not heavy snowfall in the winter time.
• Place where obstacles do not exist near the air inlet and air outlet.
• Place where the air outlet may not be exposed to a strong wind.

After finishing connection of refrigerant pipe, it shall perform air tightness test.

• The air tightness test adopts nitrogen tank to give pressure according to the pipe connection mode as the following figure shown.
• The gas and liquid valve are all in close state. In order to prevent the nitrogen entering the circulation system of outdoor unit, tighten the valve rod before giving pressure (both gas and liquid valve rods).

1) Pressurize for over 3 minutes at 0.3MPa (3.0kg / cm^2g)
2) Pressurize for over 3 minutes at 1.5 MPa ( 15 ~kg / cm^2 ~g ). A large leakage will be found.
3) Pressurize for about 24 hours at 3.0MPa ( 30kg/cm^2g ). A small leakage will be found.

• Check if the pressure drops

If the pressure does not drop, then pass.

If the pressure drops, then please check the leaking point.

When pressurizing for 24 hours, a variation of 1^ in the ambient temperature will cause a variation of 0.01MPa(0.1kg/cm^2g) in pressure. It shall be corrected during test.

• Checking the leaking point

In 1) to 3) steps, if the pressure drops, check the leakage in each joint by listening, touching and using soap water etc. to identify the leaking point. After confirming the leaking point, welding it again or tighten the nut tightly again.

Piping vacuum method: to use vacuum pump (e.g.1U18FS1ERA)

1. Detach the service port's cap of 3-way valve, the valve rod's cap for 2-way valve and 3-way valves, and connect the service port into the projection of charge hose (low) for gaugemanifold. Then connect the projection of charge hose (center) for gaugemanifold into vacuum pump.
2. Open the handle at low in gaugemanifold, and operate vacuum pump. If the scale-moves of gauge (low) reach vacuum condition in a moment, check the step 1 again.
3. Vacuumize for over 15min. And check the level gauge which should read - 0.1MPa (-76 cm Hg) at low pressure side. After the completion of vacuumizing, close the handle 'Lo' in the vacuum pump. Check the condition of the scale and hold it for 1-2min. If the scale-moves back in spite of tightening, make flaring work again, then return to the beginning of the step 3.
4. Open the valve rod for the 2-way valve to an angle of anticlockwise 90 degree. After 6 seconds, close the 2-way valve and make the inspection of gas leakage.

2 way valve

3 way valve

1. No gas leakage? In case of gas leakage, tighten parts of pipe connection. If leakage stops, then proceed the step 6. If it does not stop gas leakage, discharge whole refrigerants from the service port. After flaring work again and vacuumize, fill up prescribed refrigerant from the gas cylinder.
2. Detach the charge hose from the service port, open 2-way valve and 3-way. Turn the valve rod anticlockwise until hitting lightly.
3. To prevent the gas leakage, turn the service ports cap, the valve rodis cap for 2-way valve and 3-way's a little more than the point where the torque increases suddenly.

CAUTION:

If the refrigerant of the air conditioner leaks, it is necessary to make all the refrigerant out. Vacuumize first, then charge the liquid refrigerant into air conditioner according to the amount marked on the nameplate.

WARNING!

DANGER OF BODILY INJURY OR DEATH

• TURN OFF ELECTRIC POWER AT CIRCUIT BREAKER OR POWER SOURCE BEFORE MAKING ANY ELECTRIC CONNECTIONS.

• GROUND CONNECTIONS MUST BE COMPLETED BEFORE MAKING LINE VOLTAGE CONNECTIONS.

Precautions for Electrical wiring

• Electrical wiring work should be conducted only by authorized personnel.
• Do not connect more than three wires to the terminal block. Always use round type crimped terminal lugs with insulated grip on the ends of the wires.
• Use copper conductor only.

Selection of size of power supply and interconnecting wires

Select wire sizes and circuit protection from table below. (This table shows 20 m length wires with less than 2% voltage drop.)

• If the supply cord is damaged, it must be replaced by the manufacturer or its service agent or a similar qualified person.
• If the fuse of control box is broken, please change it with the type of T 25A/250V.
• The wiring method should be in line with the local wiring standard.
• The power cable and connecting cable should be self-provided.
• All the cables shall have got the European authentication certificate. During installation, when the connecting cables break off, it must be assured that the grounding wire is the last one to be broken off.
• The breaker of the air conditioner should be all-pole switch; and the distance between its two contacts should not be no less than 3mm . Such means for disconnection must be incorporation in the fixed wiring.
• The distance between its two terminal blocks of indoor unit and outdoor unit should not be over 5m . If exceeded, the diameter of the wire should be enlarged according to the local wiring standard.
• A leakage breaker must be installed.

Wiring procedure

1) Remove set screws on the side before taking off the front panel toward the direction.
2) Connect wires to the terminal block correctly and fix the wires with a wire clamp equipped nearby the terminal block.
3) Route the wires in a proper way and penetrate the wires through the opening for electrical wiring on the side panel.
