<Color: yellow>

Warning:

Carefully read the labels affixed to the main unit.

Warning:

• Ask the dealer or an authorized technician to install the air conditioner.

- Improper installation by the user may result in water leakage, electric shock, or fire.

• Install the unit at a place that can withstand its weight.

- Inadequate strength may cause the unit to fall down, resulting in injuries.

• Use the specified cables for wiring. Make the connections securely so that the outside force of the cable is not applied to the terminals.

- Inadequate connection and fastening may generate heat and cause a fire.

• Prepare for strong winds and earthquakes and install the unit at the specified place.

- Improper installation may cause the unit to topple and result in injury.

• Always use an filter and other accessories specified by Mitsubishi Electric.

- Ask an authorized technician to install the accessories. Improper installation

by the user may result in water leakage, electric shock, or fire.

• Never repair the unit. If the air conditioner must be repaired, consult the dealer.

- If the unit is repaired improperly, water leakage, electric shock, or fire may

result.

• Do not touch the heat exchanger fins.

- Improper handling may result in injury.

• If refrigerant gas leaks during installation work, ventilate the room.

- If the refrigerant gas comes into contact with a flame, poisonous gases will

be released.

• Install the air conditioner according to this Installation Manual.

- If the unit is installed improperly, water leakage, electric shock, or fire may

result.

• Have all electric work done by a licensed electrician according to “Electric Facility Engineering Standard” and “Interior Wire Regulations”and the instructions given in this manual and always use a special circuit.

- If the power source capacity is inadequate or electric work is performed im-

properly, electric shock and fire may result.

• Securely install the outdoor unit terminal cover (panel).

- If the terminal cover (panel) is not installed properly, dust or water may enter the outdoor unit and fire or electric shock may result.

• When installing and moving the air conditioner to another site, do not charge it with a refrigerant different from the refrigerant specified on the unit.

- If a different refrigerant or air is mixed with the original refrigerant, the refrig-

erant cycle may malfunction and the unit may be damaged.

• If the air conditioner is installed in a small room, measures must be taken to prevent the refrigerant concentration from exceeding the safety limit if the refrigerant should leak.

- Consult the dealer regarding the appropriate measures to prevent the safety

limit from being exceeded. Should the refrigerant leak and cause the safety limit to be exceeded, hazards due to lack of oxygen in the room could result.

• When moving and reinstalling the air conditioner, consult the dealer or an authorized technician.

- If the air conditioner is installed improperly, water leakage, electric shock, or

fire may result.

• After completing installation work, make sure that refrigerant gas is not leaking.

- If the refrigerant gas leaks and is exposed to a fan heater, stove, oven, or

other heat source, it may generate noxious gases.

• Do not reconstruct or change the settings of the protection devices.

- If the pressure switch, thermal switch, or other protection device is shorted

and operated forcibly, or parts other than those specified by Mitsubishi Electric are used, fire or explosion may result.

• To dispose of this product, consult your dealer.

• The installer and system specialist shall secure safety against leakage according to local regulation or standards.

- Following standards may be applicable if local regulation are not available.

• Pay special attention to the place of installation, such as a basement, etc. where refrigeration gas can accumulate, since refrigeration is heavier than the air.

1.2. Precautions for devices that use R407C

refrigerant

• Use refrigerant piping made of phosphorus deoxidized copper and copper alloy seamless pipes and tubes. In addition, be sure that the inner and outer surfaces of the pipes are clean and free of hazardous sulphur, oxides, dust/dirt, shaving particles, oils, moisture, or any other contaminant.

- Contaminants on the inside of the refrigerant piping may cause the refriger-

ant residual oil to deteriorate.

• Store the piping to be used during installation indoors and keep both ends of the piping sealed until just before brazing. (Store elbows and other joints in a plastic bag.)

- If dust, dirt, or water enters the refrigerant cycle, deterioration of the oil and

compressor trouble may result.

• 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 fill the system.

- If gas refrigerant is used to seal the system, the composition of the refriger-

ant in the cylinder will change and performance may drop.

• Do not use a refrigerant other than R407C.

- If another refrigerant (R22, etc.) is mixed with R407C, 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 are used with conventional refrigerants. (Gauge manifold, charge hose, gas leak detector, reverse flow check valve, refrigerant charge base, 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 conven-

tional 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 into the refrigerant cycle, the refrigerant may dete-

riorate.

1.3. Caution concerning equipment used for

replacement

• Do not operate the valve before conducting mineral oil recovery operation.

- Operating valves before conducting mineral oil recovery operation may cause

a deterioration in the performance of mineral oil recovery.

• For mineral oil recovery operation, the system controller and MA remote controller may be required to be remove sometimes.

- Improper handling can lead to an inability to perform oil recovery operation.

- For removal, follow the instruction displayed on the PC for mineral recovery.

- Mount the controllers again after finishing the oil recovery operation.

• Observe a safe distance from the indoor unit fan, which runs during the mineral oil recovery operation.

- Working in the surrounding of the indoor unit fan can cause personal injury.

• Record the quantity of refrigerant replenished. (Enter into the column for replenished refrigerant quantity on the label of the indoor unit.)

- Missing the description may deteriorate the performance of mineral oil re-

covery.

- Malfunction or poor cooling/heating may also be caused.

• During the mineral oil recovery operation, an error display may be shown on the remote controller or system controller.

- When an error display was shown during mineral oil recovery operation, re-

set the error display after finishing the operation.

• To conduct the refrigerant recovery/evacuation of the inside of exiting piping, choose tools only used with R407C e.g. charging hose.

- Using a charging hose for R407C causes it to mix the conventional refriger-

ating machine oil leading to the deterioration of refrigerating machine oil.

Items to be observed

• Please note that our Corporation is not liable to the reliability of existing piping, wiring and power system for reuse (in relation with the gas leak of piping, partially defective/disconnection of wiring, deteriorated insulation, characteristic faults due to worn out system).

• For limitation on the refrigerant piping and applicable piping diameter, check the existing piping for reuse in accordance with the specified check sheet by referring products catalogs and manuals for judgement to reuse.

• If vapor condensation was found in the past, check the thermal insulation.

• For a portion suffered by condensation dripping, check the deterioration of the insulation, and repair the insulation materials if required.

• When the copper piping is seriously deteriorated, do not use parts with verdigris or black spots.

• For reusing the existing control wiring between the outdoor unit, and remote controller, check the wire type, size or the like based on the check sheet to judge the possibility.

• Even when the above does not meet the item on the check sheet, existing wiring may be reused depending on the number of connecting indoor units and piping length. Ask us for detail.

• For the power source system employ the voltage and number of phase meeting the outdoor unit, indoor unit and heat storage unit, and adopt the breaker capacity and wiring size based on the power source wiring connection diagram.

• When the existing power source system (including the power source wiring) is used, check the system for deterioration and damages.

• Check the refrigerating machine oil used in the existing system. (As is found at the oil inspection, if the refrigerating machine oil used in the existing system is mineral oil, use the ester oil sampling kit for inspection.

• When the length of piping for reuse is unknown, additional refrigerant charge is to be calculated based on the quantity of recovered refrigerant. For this reason, you are kindly requested to recover all refrigerant inside the existing outdoor/indoor units and extended piping to check and record the quantity, (The standard of additional refrigerant is (Quantity of R22 recovered - Charged quantity of existing outdoor unit + 3kg). Adjust the refrigerant quantity after mineral oil recovery operation.)

■ Outdoor unit

• Confirm the space around the outdoor unit.

(Verifying the installation space of the oil trap kit)

■ Turn the power sources on, and confirm the normality of the system

• Check the remote controller or outdoor unit for error display.

• Run the indoor unit for fan operation after turning the remote controller on, and check the air

feeding and direction.

Do not run the compressor until finishing the mineral oil recovery operation.

the air conditioner or damage its parts.

• When installing the unit in a hospital, communication station, or similar place, provide sufficient protection against noise.

- Inverter equipment, private power generator, high-frequency medical equip-

ment, or radio communication equipment may cause the air conditioner to operate erroneously, or fail to operate. On the other hand, the air conditioner may affect such equipment by creating noise that disturbs medical treatment or image broadcasting.

• Do not install the unit on a structure that may cause leakage.

- When the room humidity exceeds 80 % or when the drain pipe is clogged,

condensation may drip from the indoor unit. Perform collective drainage work together with the outdoor unit, as required.

1.5. Before installation - electrical work

Caution:

• Ground the unit.

- Do not connect the ground wire to gas or water pipes, lightning rods, or

telephone ground lines. Improper grounding may result in electric shock.

• The reverse phase of L lines (L

1, L2, L3) can detected (Error cord: 4103),

but the reverse phase of L lines and N line can not be detected.

- Some electric parts may be damaged when power is supplied during miss

wiring.

• Install the power cable so that tension is not applied to the cable.

- Tension may cause the cable to break and generate heat and cause a fire.

• Install a leak circuit breaker, as required.

- If a leak circuit breaker is not installed, electric shock may result.

• Use power line cables of sufficient current carrying capacity and rating.

- Cables that are too small may leak, generate heat, and cause a fire.

• Use only a circuit breaker and fuse of the specified capacity.

- A fuse or circuit breaker of a larger capacity, a steel or copper wire may result

in a general unit failure or fire.

• Do not wash the air conditioner units.

- Washing them may cause an electric shock.

• Be careful about that the installation base is not damaged by long use.

- If the damage is left uncorrected, the unit may fall and cause personal injury

or property damage.

• Install the drain piping according to this Installation Manual to ensure proper drainage. Wrap thermal insulation around the pipes to prevent condensation.

- Improper drain piping may cause water leakage causing damage to furniture

and other possessions.

• Be very careful about transporting the product.

- One person should not carry the product as it weighs more than 20 kg.

- Some products use PP bands for packaging. Do not use any PP bands as a

means of transportation. It is dangerous.

- Do not touch the heat exchanger fins. Doing so may cut your fingers.

- When transporting the outdoor unit, support it at the specified positions on

the unit base. Also support the outdoor unit at four points so that it cannot slip sideways.

• Safely dispose of the packing materials.

- Packing materials, such as nails and other metal or wooden parts, may cause

stabs or other injuries.

- Tear apart and throw away plastic packaging bags so that children will not

play with them. If children play with a plastic bag which was not torn apart, they face the risk of suffocation.

1.6. Before starting the test run

Caution:

• Turn on the power at least 12 hours before starting operation.

- Starting operation immediately after turning on the main power switch can

result in irreversible damage to internal parts. Keep the power switch turned on during the operational season.

PGRRUTR

7. Refrigerant piping installation

(1) Before mineral oil recovery

In order to perform vacuum drawing and ensure the gas-tightness of the refrigerant pipes connected to the indoor unit, it is necessary to fit a valve (supplied with outdoor unit). Make the liquid side a flare connection and the gas side a brazed connection. (If the pipe diameter of the current onsite pipe is ø25.4 mm, connect using the connecting pipe 2 (supplied with the outdoor unit)).

CAUTION:

• The refrigerant pipes connected to the indoor unit and the outdoor unit will be connected to the oil trap kit when recovering the mineral oil and so do not connect the pipes.

• Allow for the connection to the outdoor unit and oil trap kit when installing the valve. (The total length of the piping should be 5m or less.)

(2) After mineral oil recovery

Connecting the piping is a terminal-branch type in which refrigerant piping from the outdoor unit is branched at the terminal and connected to each of the indoor units. The method of connection consists of flare connections at the indoor units, flange connections for the piping of the outdoor unit and flare connections for the liquid piping. Note that the branched sections are brazed.

Warning:

Always use extreme care to prevent the refrigerant gas from leaking while using fire or flame. If the refrigerant gas comes in contact with the flame from any source, such as a gas stove, it breaks down and generates a poisonous gas which can cause gas poisoning. Never weld in an unventilated room. Always conduct an inspection for gas leakage after installation of the refrigerant piping has been completed.

7.1. Caution

1 Use the following materials for refrigeration piping.

• Material: Use refrigerant piping made of phosphorus deoxidized copper.

In addition, be sure that the inner and outer surfaces of the pipes are clean and free of hazardous sulphur, oxides, dust/dirt, shaving particles, oils, moisture, or any other contaminant.

2 Commercially available piping often contains dust and other materials. Always

blow it clean with a dry inert gas.

3 Use care to prevent dust, water or other contaminants from entering the piping

during installation.

4 Reduce the number of bending portions as much as possible, and make bend-

ing radius as big as possible.

5 Always observe the restrictions on the refrigerant piping (such as rated length,

the difference between high/low pressures, and piping diameter). Failure to do so can result in equipment failure or a decline in heating/cooling performance.

6 Replace multi will stop due to an abnormality due to excessive or insufficient

coolant. At such a time, always properly charge the unit. When servicing, always check the notes concerning pipe length and amount of additional refrigerant at both locations, the refrigerant volume calculation table on the back of the service panel and the additional refrigerant section on the labels for the combined number of indoor units. If the refrigerant could not be charged to the prescribed amount, show the insufficient portion on the labeling.

7 Use liquid refrigerant to fill the system. 8 Never use refrigerant to perform an air purge. Always evacuate using a vacuum

pump.

9 Always insulate the piping properly. Insufficient insulation will result in a de-

cline in heating/cooling performance, water drops from condensation and other such problems.

0 When connecting the refrigerant piping, make sure the ball valve of the out-

door unit is completely closed (the factory setting) and do not operate it until the refrigerant piping for the outdoor and indoor units has been connected and the mineral oil recovery operation has been completed.

A Always use a non-oxidizing brazing material for brazing the parts. If a non-

oxidizing brazing material is not used, it could cause clogging or damage to the compressor unit.

B Never perform outdoor unit piping connection work when it is raining.

Warning:

When installing and moving the unit, do not charge it with refrigerant other than the refrigerant specified on the unit.

- Mixing of a different refrigerant, air, etc. may cause the refrigerant cycle to malfunction and result in severe damage.

Caution:

• Use a vacuum pump with a reverse flow check valve.

- If the vacuum pump does not have a reverse flow check valve, the vacuum pump oil may flow back into the refrigerant cycle and cause deterioration of the refrigerator oil and other trouble.

• Do not use the tools shown below used with conventional refrigerant. (Gauge manifold, charge hose, gas leak detector, check valve, refrigerant charge base, vacuum gauge, refrigerant recovery equipment)

- Mixing of conventional refrigerant and refrigerator oil may cause the refrig-

erator oil to deteriorate.

- Mixing of water will cause the refrigerator oil to deteriorate.

- R407C refrigerant does not contain any chlorine. Therefore, gas leak detec-

tors for conventional refrigerants will not react to it.

• Manage the tools more carefully than normal.

- If dust, dirt, or water gets in the refrigerant cycle, the refrigerator oil will dete-

riorate.

• Refer to the Installation manual concerning whether you can use an existing refrigerant piping.

- Depending on the type, old refrigeration oil in the existing piping could re-

duce the effectiveness of mineral oil recovery and cause the new refrigeration oil to deteriorate.

- If you use the existing piping in a way that is outside the scope of the piping

specifications (for example, pipe diameter, pipe length and vertical interval), it will reduce the effectiveness of mineral oil recovery and will cause the new refrigeration oil to deteriorate.

• Store the piping to be used during installation indoors and keep both ends of the piping sealed until just before brazing.

- If dust, dirt, or water gets into the refrigerant cycle, the oil will deteriorate and

the compressor may fail.

• Do not use a charging cylinder.

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

• Do not use special detergents for washing piping.

A M10 anchor bolt procured at the site. B Corner is not seated.

• Fix unit tightly with bolts so that unit will not fall down due to earthquake or gust of wind.

• Use concrete or angle bracket for foundation of unit.

• Vibration may be transmitted to the installation section and noise and vibration may be generated from the floor and walls, depending on the installation conditions. Therefore, provide ample vibrationproofing (cushion pads, cushion frame, etc.).

• Be sure that the corners are firmly seated. If the corners are not firmly seated, the installation feet may be bent.

Warning:

• Be sure to install unit in a place strong enough to withstand its weight. Any lack of strength may cause unit to fall down, resulting in a personal injury.

• Have installation work in order to protect against a strong wind and earthquake. Any installation deficiency may cause unit to fall down, resulting in a personal injury.

When building the foundation, give full attention to the floor strength, drain water disposal <during operation, drain water flows out of the unit>, and piping and wiring routes.

Down piping and down wiring precautions

When down piping and down wiring are performed, be sure that foundation and base work does not block the base through holes. When down piping is performed, make the foundation at least 100 mm high so that the piping can pass under the bottom of the unit.

8. Additional Refrigerant Charge

Connecting to the oil trap kit side

1 Braze the ball valve on the gas side. 2 Inser t the packing, consisting of rubber bushing with membrane, and fit the

connecting pipe with flange to isolate the refrigerant circuit.

• When the valve is open, it obstructs the mineral oil recovery operation so this valve must be in the closed position.

• Determine the amount of additional refrigerant charge by using the formula, and charge refrigerant additionally through the service port after completing piping connection work.

• Refer to “(2) After mineral oil recovery” for the required tightening torque.

(2) After mineral oil recovery

• Conduct piping connection and valve operation accurately.

• The gas side connecting pipe is assembled in factory before shipment. 1 For brazing to the connecting pipe with flange, remove the connecting pipe

with flange from the ball valve, and braze it outside of the unit.

2 During the time when removing the connecting pipe with flange, remove

the seal attached on the rear side of this sheet and paste it onto the flange surface of the ball valve to prevent the entry of dust into the valve.

3 The refrigerant circuit is closed with a round, close-packed packing upon

shipment to prevent gas leak between flanges. As no operation can be done under this state, be sure to replace the packing with the hollow packing attached at the piping connection.

4 At the mounting of the hollow packing, wipe off dust attached on the flange

sheet surface and the packing. Coat refrigerating machine oil (Ester oil, ether oil or alkylbenzene [small amount]) onto both surfaces of the packing.

[Fig. 8.2.2] (P.3)

• After evacuation and refrigerant charge, ensure that the handle is fully open. If operating with the valve closed, abnormal pressure will be imparted to the high- or low-pressure side of the refrigerant circuit, giving damage to the compressor, four-way valve, etc.

• Determine the amount of additional refrigerant charge by using the formula, and charge refrigerant additionally through the service port after completing piping connection work.

• After completing work, tighten the service port and cap securely not to generate gas leak.

L Close-packed packing M Hollow packing

At the time of shipping, the outdoor unit is charged with the refrigerant. As this charge does not include the amount needed for extended piping, additional charging for each refrigerant line will be required on site. Note that the method used for calculating the additional refrigerant charge for a Replace Multi is different to that used for the Y Series. In order that future servicing may be properly provided, always keep a record of the size and length of each refrigerant line and the amount of additional charge by writing it in the space provided on the outdoor unit.

8.1. Calculation of Additional Refrigerant Charge

• Calculate the amount of additional charge based on the length of the piping

extension and the size of the refrigerant line.

• Use the table to the right as a guide to calculating the amount of additional

charging and charge the system accordingly.

• If the calculation results in a fraction of less than 0.1 kg, round up to the next

0.1 kg. For example, if the result of the calculation was 12.62 kg, round the result up to 12.7 kg.

At the conditions below:

<Example> Indoor 1: 40 A: ø12.7 40 m a: ø6.35 10 m

2: 100 B: ø12.7 10 m b: ø9.52 5 m 3: 40 C: ø12.7 15 m c: ø6.35 10 m 4: 32 D: ø12.7 10 m d: ø6.35 10 m

5: 63 e: ø9.52 10 m The total length of each liquid line is as follows: ø12.7: A + B + C + D = 40 + 10 + 15 + 10 = 75 m ø9.52: b + e = 5 + 10 = 15 m ø6.35: a + c + d = 10 + 10 + 10 = 30 m Therefore, <Calculation example> Additional refrigerant charge

= 75 × 0.12 + 15 × 0.06 + 30 × 0.024 – 2 = 8.7 kg

Value of α

2.0 kg

• If it is calculated that the additional refrigerant amount is 0.5kg or less, the

additional refrigerant amount is to be 0.5 kg.

Note: If a torque wrench is not available, use the following method as a standard: When you tighten the flare nut with a wrench, you will reach a point where the tightening torque will abruptly increase. Turn the flare nut beyond this point by the angle shown in the table above.

Caution:

• Always remove the connecting pipe from the ball valve and braze it outside the unit.

- Brazing the connecting pipe while it is installed will heat the ball valve and

cause trouble or gas leakage. The piping, etc. inside the unit may also be burned.

• Use ester oil, ether oil or alkylbenzene (small amount) as the refrigerating machine oil to coat flares and flange connections.

- The refrigerating machine oil will degrade if it is mixed with a large amount of

mineral oil.

• Do not use a leak detection additive.

8.3. Airtight test, evacuation, and refrigerant

charging

1 Airtight test

Perform with the ball valve of the refrigerant piping that is connected to the indoor unit closed, and pressurize the connection piping and the indoor unit from the service port provided on the ball valve of the refrigerant piping that is connected to the indoor unit. (Always pressurize from both the high press pipe and the low press pipe service ports.)

[Fig. 8.3.1] (P.3)

A Nitrogen gas B To indoor unit C System analyzer D Lo Knob E Hi Knob F Ball valve G Liquid pipe H Gas pipe I To oil trap kit J Service port

The method of conducting the airtight test is basically the same as for R22 models. However, since the restrictions have a large affect on deterioration of the refrigerating machine oil, always observe them. Also, with nonazeotropic refrigerant (R407C, etc.), gas leakage causes the composition to change and affects performance. Therefore, perform the airtightness test cautiously.

Restriction

• If a flammable gas or air (oxygen) is used as the pressurization gas, it may catch fire or explode.

• Do not use a refrigerant other than that indicated on the unit.

• Sealing with gas from a cylinder will cause the composition of the refrigerant in the cylinder to change.

• Use a pressure gauge, charge box, and other parts especially for R407C.

• An electric leak detector for R22 cannot detect leaks of R407C.

• Do not use a haloid torch. (Leaks cannot be detected.)

Airtight test procedure

1. Nitrogen gas pressurization (1) After pressurizing to the design pressure (2.94 MPa) using nitrogen gas, allow it to stand for

about one day. If the pressure does not drop, airtightness is good. However, if the pressure drops, since the leaking point is unknown, the following bubble test may also be performed.

(2) After the pressurization described above, spray the flare connection parts, brazed parts, flanges,

and other parts that may leak with a bubbling agent (Kyuboflex, etc.) and visually check for bubbles.

(3) After the airtight test, wipe off the bubbling agent.

2. Pressurization using refrigerant gas and nitrogen gas (1) Pressurizing to a gas pressure of approximately 0.2 MPa, pressurize to the design pressure

(2.94 MPa) using nitrogen gas. However, do not pressurize at one time. Stop during pressurization and check that the pressure does not drop.

(2) Check for gas leaks by checking the flare connection parts, brazed parts, flanges, and other

parts which may leak using an R407C compatible electric leak detector.

(3) This test may be used together the with bubble type gas leak test.

2 Evacuation

Evacuate with the ball valve of the refrigerant piping that is connected to the indoor unit closed, and evacuate both the connection piping and the indoor unit from the service port provided on the ball valve of the refrigerant piping that is connected to the indoor unit using a vacuum pump. (Always evacuate from the service port of both the high press pipe and the low press pipe.) After the vacuum reaches 650 Pa [abs], continue evacuation for at least one hour or more. * Never perform air purging using refrigerant.

[Fig. 8.3.2] (P.3)

A System analyzer B Lo Knob C Hi Knob D Ball valve E Liquid pipe F Gas pipe G Service port H Three-way joint I Valve J Valve K Cylinder L Scale M Vacuum pump

Note:

• Always add an appropriate amount of refrigerant. Also always seal the system with liquid refrigerant. Too much or too little refrigerant will cause trouble.

• Use a gauge manifold, charging hose, and other parts for the refrigerant indicated on the unit.

• Use a graviometer. (One that can measure down to 0.1 kg.)

• Use a vacuum pump with a reverse flow check valve. (Recommended vacuum gauge: ROBINAIR 14830A Thermistor Vacuum Gauge) Also use a vacuum gauge that reaches 0.5 Torr or greater after operating for five minutes.

3 Refrigerant Charging

Since the refrigerant used with the unit is nonazerotropic, it must be charged in the liquid state. Consequently, when charging the unit with refrigerant from a cylinder, if the cylinder does not have a syphon pipe, charge the liquid refrigerant by turning the cylinder upside-down as shown below. If the cylinder has a syphon pipe like that shown in the figure at the right, the liquid refrigerant can be charged with the cylinder standing upright. Therefore, give careful attention

to the cylinder specifications. If the unit should be charged with gas refrigerant, replace all the refrigerant with new refrigerant. Do not use the refrigerant remaining in the cylinder.

[Fig. 8.3.3] (P.3)

<In case of the cylinder having no syphon pipe.> A Syphon pipe

8.4. Thermal insulation of refrigerant piping

Be sure to give insulation work to refrigerant piping by covering liquid pipe and gas pipe separately with enough thickness heat-resistant polyethylene, so that no gap is observed in the joint between indoor unit and insulating material, and insulating materials themselves. When insulation work is insufficient, there is a possibility of condensation drip, etc. Pay special attention to insulation work to ceiling plenum.

9.1. Caution

1 Follow ordinance of your governmental organization for technical standard re-

lated to electrical equipment, wiring regulations and guidance of each electric power company.

2 Wiring for control (hereinafter referred to as transmission line) shall be (5 cm

or more) apart from power source wiring so that it is not influenced by electric noise from power source wiring. (Do not insert transmission line and power source wire in the same conduit.)

3 Be sure to provide designated grounding work to outdoor unit. 4 Give some allowance to wiring for electrical part box of indoor and outdoor

units, because the box is sometimes removed at the time of service work.

5 Never connect the main power source to terminal block of transmission line. If

connected, electrical parts will be burnt out.

6 Use 2-core shield cable for transmission line. If transmission lines of different

systems are wired with the same multiplecore cable, the resultant poor transmitting and receiving will cause erroneous operations.

7 Only the transmission line specified should be connected to the terminal block

for outdoor unit transmission. (Transmission line to be connected with indoor unit : Terminal block TB3 for transmission line, Other : Terminal block TB7 for centralized control) Erroneous connection does not allow the system to operate.

8 In the case of connecting with an upper class controller or to conduct group

operation in different refrigerant systems, the control line for transmission is required between the outdoor units. Connect this control line between the terminal blocks for centralized control. (2-wire line with no polarity) When conducting group operation in different refrigerant systems without connecting to the upper class controller, replace the insertion of the short circuit connector from CN41 of one outdoor unit to CN40.

9 Group is set by operating the remote controller.

9.2. Control box and connecting position of wiring

1. Connect the indoor unit transmission line to transmission terminal block (TB3),

or connect the wiring between outdoor units or the wiring with the central control system to the central control terminal block (TB7). When using shielded wiring, connect shield ground of the indoor unit transmission line to the earth screw (

Because of the control operation of auto vane, it may change over to horizontal blow automatically from the downward blow in cooling in case the downward blow operation has been continued for 1 hour. At defrosting in heating, hot adjusting and thermostat OFF, it automatically changes over to horizontal blow. Ultra-low speed operation is commenced at thermostat OFF. Light air automatically changes over to set value by time or piping temperature at thermostat ON. The fan is to stop during defrosting. Fan is to run for 1 minute after stopping to exhaust residual heat (only in heating).

Ultra low-speed operation for 5 minutes after SW ON or until piping temperature becomes 35°C, low speed operation for 2 minutes thereafter, and then set notch is commenced. (Hot adjust control) When the outdoor unit is being cooled and the refrigerant is resting, warming up operation is performed for at least 35 minutes to warm the compressor. During this time, only the fan operates. System is being driven. Operate remote controller again after “HO” disappear.

After a stop of cooling operation, unit continues to operate drain pump for three minutes and then stops it. Unit continues to operate drain pump if drainage is generated, even during a stop.

Phenomenon Indoor unit does not the perform cooling (heating) operation. The auto vane runs freely.

Fan setting changes during heating.

Fan stops during heating operation. Fan does not stop while operation has been stopped. No setting of fan while start SW has been turned on.

Outdoor unit does not operate by turning switch on.

Indoor unit remote controller shows “HO” indicator for about two minutes when turning ON universal power supply. Drain pump does not stop while unit has been stopped. Drain pump continues to operate while unit has been stopped.

• Keinen Füllzylinder verwenden.

- Bei Verwendung eines Füllzylinders kann das Kältemittel verderben.

• Beim Einsatz der Handhabungsvorrichtungen besondere Sorgfalt walten lassen.

- Wenn Staub, Schmutz oder Wasser in den Kältemittelkreislauf gelangt, kann

dies zur Qualitätsminderung des Kältemittels führen.

1.3. Vorsicht in Bezug auf die zum Ersatz be-

stimmte Ausrüstung

• Die Armatur nicht vor Ausführung der Mineralölwiederaufbereitung betätigen.

- Betätigen der Armatur vor Durchführung der Mineralölwiederaufbereitung

kann eine Qualitätsverschlechterung bei der Mineralölwiederaufbereitung zur Folge haben.

• Zur Mineralölwiederaufbereitung kann es manchmal erforderlich sein, die Steuerung der Anlage und die MA-Fernbedienung abzunehmen.

- Unsachgemäße Handhabung kann dazu führen, daß die

Ölwiederaufbereitung nicht mehr möglich ist.

- Zum Abnehmen, die auf dem PC für die Mineralölwiederaufbereitung ange-

zeigten Anweisungen befolgen.

- Nach Beendigung der Ölwiederaufbereitung die Steuerungen wieder anbrin-

gen.

• Einen sicheren Abstand vom Ventilator des Innengerätes, der während der Mineralölwiederaufbereitung läuft, einhalten.

- Arbeiten in der Umgebung des Ventilators des Innengerätes können Verlet-

zungen zur Folge haben.

• Die Menge des nachgefüllten Kältemittels aufzeichnen. (In die Spalte für die Menge des wiederaufgefüllten Kältemittels auf dem Aufkleber des Innengerätes eintragen.)

- Eine Unterlassung der Beschreibung kann eine Verschlechterung der Quali-

tät der Mineralölwiederaufbereitung zur Folge haben.

- Es kann ebenfalls eine Fehlfunktion oder schlechte Kühl-/Heizleistung zur

Folge haben.

• Während der Mineralölwiederaufbereitung kann auf der Fernbedienung oder der Steuerung der Anlage eine Fehlermeldung angezeigt werden.

- Wenn während der Mineralölwiederaufbereitung eine Fehlermeldung ange-

zeigt wurde, die Fehlermeldung nach Abschluß der Aufbereitung wieder zurücksetzen.

• Zur Ausführung der Kältemittelwiederaufbereitung/Evakuierung der Innenseite einer vorhandenen Rohrleitung nur solche Werkzeuge, z.B. Füllschläuche, auswählen, die für R407C verwendet wurden.

- Die Verwendung eines Füllschlauchs für R407C führt dazu, daß es sich mit

konventionellem Kältemittelmaschinenöl vermischt, was eine Verschlechterung des Kältemittelmaschinenöls zur Folge hat.

1.2. Vorsichtsmaßnahmen für Vorrichtungen, die das Kältemittel R407C verwenden

Vorsicht:

• Für die Kältemittelrohrleitung nahtlose Rohre und Röhren aus Phosphor-

desoxidiertem Kupfer und entsprechenden Kupferlegierungen verwenden. Außerdem vergewissern, daß die Innen- und Außenflächen der Rohrleitungen sauber und frei von gefährlichem Kupfer, Oxyden, Staub/ Schmutz, Metallbearbeitungsrückständen, Ölen, Feuchtigkeit oder anderen Verunreinigungen sind.

- Verunreinigungen auf der Innenseite der Kältemittelrohrleitungen können dazu führen, daß das Kältemittelrestöl verdirbt.

• Die bei der Installation verwendete Rohrleitung in einem geschlossenen Raum aufbewahren und beide Enden bis unmittelbar vor dem Hartlöten geschlossen halten. (Krümmer und andere Rohrverbinder in einem Kunststoffbeutel aufbewahren).

- Wenn Staub, Schmutz oder Wasser in den Kältemittelkreislauf gelangt, kann

dies zu einer Qualitätsminderung des Öls und zu Kompressorstörungen führen.

• Zum Beschichten der Konus- und Flanschanschlüsse Esteröl/Ätheröl oder Alkylbenzol (kleine Menge) als Kältemaschinenöl verwenden.

- Das Kältemaschinenöl zersetzt sich, wenn es mit größeren Mengen Mine-

ralöl vermischt wird.

• Zur Füllung des Systems flüssiges Kältemittel verwenden.

- Wenn Kältemittelgas zur Füllung des Systems verwendet wird, ändert sich

die Zusammensetzung des Kältemittels im Zylinder, so daß die Leistung abfallen kann.

• Kein anderes Kältemittel als R407C verwenden.

- Wenn ein anderes Kältemittel (R22 usw.) mit R407C gemischt wird, kann

das im Kältemittel enthaltene Chlor Verschlechterung des Kältemaschinenöls verursachen.

• Eine Vakuumpumpe mit einem Reverse Flow (Gegenstrom)- Rückschlagventil verwenden.

- Das Öl der Vakuumpumpe fließt in den Kältemittelkreislauf zurück und führt

zur Qualitätsminderung des Kältemaschinenöls.

• Folgende Vorrichtungen, die bei herkömmlichen Kältemitteln verwendet werden, nicht einsetzen. (Meßrohrleitung, Füllschlauch, Gasaustrittsdetektor, Reverse Flow (Gegenstrom)- Rückschlagventil, Kältemittelfüllständer, Kältemittelaufbereitungseinrichtungen)

- Wenn ein herkömmliches Kältemittel und Kältemaschinenöl mit R407C vermischt

werden, kann dies zur Qualitätsminderung des Kältemaschinenöls führen.

- Wenn R407C mit Wasser vermischt wird, kann dies zur Qualitätsminderung

des Kältemaschinenöls führen.

- Da R407C kein Chlor enthält, reagieren Gasaustrittssuchgeräte für herkömm-

liche Kältemittel nicht darauf.
