WARNING

Securely attach the terminal block cover (panel) to the unit.

If the terminal block cover (panel) is not installed properly, dust and/or water may infiltrate and pose a risk of electric shock, smoke, and/or fire.

Only use the type of refrigerant that is indicated on the unit when installing or reinstalling the unit.

Infiltration of any other type of refrigerant or air into the unit may adversely affect the refrigerant cycle and may cause the pipes to burst or explode.

When installing the unit in a small room, exercise caution and take measures against leaked refrigerant reaching the limiting concentration.

Consult your dealer with any questions regarding limiting concentrations and for precautionary measures before installing the unit. Leaked refrigerant gas exceeding the limiting concentration causes oxygen deficiency.

Consult your dealer or a specialist when moving or reinstalling the unit.

Improper installation may result in water leakage, electric shock, and/or fire.

After completing the service work, check for a gas leak.

If leaked refrigerant is exposed to a heat source, such as a fan heater, stove, or electric grill, poisonous gases may be produced.

Do not try to defeat the safety features of the unit.

Forced operation of the pressure switch or the temperature switch by defeating the safety features of these devices, or the use of accessories other than the ones that are recommended by MITSUBISHI may result in smoke, fire, and/or explosion.

Precautions for handling units for use with R410A

CAUTION

Do not use the existing refrigerant piping.

A large amount of chlorine that is contained in the residual

refrigerant and refrigerator oil in the existing piping may cause the refrigerator oil in the new unit to deteriorate.

R410A is a high-pressure refrigerant and can cause the

existing pipes to burst.

Use refrigerant pipes made of phosphorus deoxidized copper. Keep the inner and outer surfaces of the pipes clean and free of such contaminants as sulfur, oxides, dust, dirt, shaving particles, oil, and water.

These types of contaminants inside the refrigerant pipes may cause the refrigerant oil to deteriorate.

Store the pipes to be installed indoors, and keep both ends of the pipes sealed until immediately before brazing. (Keep elbows and other joints wrapped in plastic.)

Infiltration of dust, dirt, or water into the refrigerant system may cause the refrigerating machine oil to deteriorate or cause the unit to malfunction.

Use a small amount of ester oil, ether oil, or alkylbenzene to coat flares and flanges.

Infiltration of a large amount of mineral oil may cause the refrigerating machine oil to deteriorate.

Charge liquid refrigerant (as opposed to gaseous refrigerant) into the system.

If gaseous refrigerant is charged into the system, the composition of the refrigerant in the cylinder will change and may result in performance loss.

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

If a vacuum pump that is not equipped with a reverse-flow check valve is used, the vacuum pump oil may flow into the refrigerant cycle and cause the refrigerating machine oil to deteriorate.

Prepare tools for exclusive use with R410A. Do not use the following tools if they have been used with the conventional refrigerant (gauge manifold, charging hose, gas leak detector, reverse-flow check valve, refrigerant charge base, vacuum gauge, and refrigerant recovery equipment.).

If the refrigerant or the refrigerating machine oil left on

these tools are mixed in with R410A, it may cause the refrigerating machine oil to deteriorate.

Infiltration of water may cause the refrigerating machine

oil to deteriorate.

Gas leak detectors for conventional refrigerants will not

detect an R410A leak because R410A is free of chlorine.

Do not use a charging cylinder.

If a charging cylinder is used, the composition of the refrigerant will change, and the unit may experience power loss.

Exercise special care when handling the tools for use with R410A.

Infiltration of dust, dirt, or water into the refrigerant system may cause the refrigerating machine oil to deteriorate.

Only use refrigerant R410A.

The use of other types of refrigerant that contain chlorine (i.e. R22) may cause the refrigerating machine oil to deteriorate.

HWE0713A GB

iiiiii

Before installing the unit

WARNING

Do not install the unit where a gas leak may occur.

If gaseous refrigerant leaks and piles up around the unit, it may be ignited.

Do not use the unit to keep food items, animals, plants, artifacts, or for other special purposes.

The unit is not designed to preserve food products.

Do not use the unit in an unusual environment.

Do not install the unit where a large amount of oil or steam

is present or where acidic or alkaline solutions or chemical sprays are used frequently. Doing so may lead to a remarkable drop in performance, electric shock, malfunctions, smoke, and/or fire.

The presence of organic solvents or corrosive gas (i.e.

ammonia, sulfur compounds, and acid) may cause gas leakage or water leakage.

When installing the unit in a hospital, take appropriate measures to reduce noise interference.

High-frequency medical equipment may interfere with the normal operation of the air conditioner or vice versa.

iv

Before installing the unit (moving and reinstalling the unit) and performing electrical work

CAUTION

Properly ground the unit.

Do not connect the grounding wire to a gas pipe, water pipe, lightning rod, or grounding wire from a telephone pole. Improper grounding may result in electric shock, smoke, fire, and/or malfunction due to noise interference.

Do not put tension on the power supply wires.

If tension is put on the wires, they may break and result in excessive heat, smoke, and/or fire.

Install an earth leakage breaker to avoid the risk of electric shock.

Failure to install an earth leakage breaker may result in electric shock, smoke, and/or fire.

Use the kind of power supply wires that are specified in the installation manual.

The use of wrong kind of power supply wires may result in current leak, electric shock, and/or fire.

Use breakers and fuses (current breaker, remote switch <switch + Type-B fuse>, moulded case circuit breaker) with the proper current capacity.

The use of wrong capacity fuses, steel wires, or copper wires may result in malfunctions, smoke, and/or fire.

Periodically check the installation base for damage.

If the unit is left on a damaged platform, it may fall and cause injury.

Properly install the drain pipes according to the instructions in the installation manual. Keep them insulated to avoid dew condensation.

Improper plumbing work may result in water leakage and damage to the furnishings.

Exercise caution when transporting products.

Products weighing more than 20 kg should not be carried

alone.

Do not carry the product by the PP bands that are used on

some products.

Do not touch the heat exchanger fins. They are sharp and

dangerous.

When lifting the unit with a crane, secure all four corners

to prevent the unit from falling.

Properly dispose of the packing materials.

Nails and wood pieces in the package may pose a risk of

injury.

Plastic bags may pose a risk of choking hazard to chil-

dren. Tear plastic bags into pieces before disposing of them.

Do not spray water on the air conditioner or immerse the air conditioner in water.

Otherwise, electric shock and/or fire may result.

When handling units, always wear protective gloves to protect your hands from metal parts and high-temperature parts.

HWE0713A GB

vv

Before the test run

CAUTION

To avoid the risk of electric shock or malfunction of the unit, do not operate switches with wet hands.

Do not touch the refrigerant pipes with bare hands during and immediately after operation.

During or immediately after operation, certain parts of the unit such as pipes and compressor may be either very cold or hot, depending on the state of the refrigerant in the unit at the time. To reduce the risk of frost bites and burns, do not touch these parts with bare hands.

Do not operate the unit without panels and safety guards.

Rotating, high-temperature, or high-voltage parts on the unit pose a risk of burns and/or electric shock.

Do not turn off the power immediately after stopping the operation.

Keep the unit on for at least five minutes before turning off the power to prevent water leakage or malfunction.

Do not operate the unit without the air filter.

Dust particles may build up in the system and cause malfunctions.

[3] Piping Materials

Do not use the existing piping!

1. Copper pipe materials

O-material (Annealed) Soft copper pipes (annealed copper pipes). They can easily be bent with hands.

1/2H-material (Drawn) Hard copper pipes (straight pipes). They are stronger than the O-material (Annealed)

at the same radial thickness.

The distinction between O-materials (Annealed) and 1/2H-materials (Drawn) is made based on the strength of the pipes them-

selves.

2. Types of copper pipes

Maximum working pressure Refrigerant type

3.45 MPa [500psi] R22, R407C etc.

4.30 MPa [624psi] R410A etc.

3. Piping materials/Radial thickness

Use refrigerant pipes made of phosphorus deoxidized copper. The operation pressure of the units that use R410A is higher than that of the units that use R22. Use pipes that have at least the radial thickness specified in the chart below. (Pipes with a radial thickness of 0.7 mm or less may not be used.)

Pipe size (mm[in]) Radial thickness (mm) Type

ø6.35 [1/4"] 0.8t

ø9.52 [3/8"] 0.8t

ø12.7 [1/2"] 0.8t

ø15.88 [5/8"] 1.0t

ø19.05 [3/4"] 1.0t

ø22.2 [7/8"] 1.0t

ø31.75 [1-1/4"] 1.1t

ø34.93 [1-3/8"] 1.1t

ø41.28 [1-5/8"] 1.2t

The pipes in the system that uses the refrigerant currently on the market are made with O-material (Annealed), even if the

pipe diameter is less than ø19.05 (3/4"). For a system that uses R410A, use pipes that are made with 1/2H-material (Drawn) unless the pipe diameter is at least ø19.05 (3/4") and the radial thickness is at least 1.2t.

The figures in the radial thickness column are based on the Japanese standards and provided only as a reference. Use pipes

that meet the local standards.

4. Thickness and refrigerant type indicated on the piping materials

Ask the pipe manufacturer for the symbols indicated on the piping material for new refrigerant.

5. Flare processing (O-material (Annealed) and OL-material only)

The flare processing dimensions for the pipes that are used in the R410A system are larger than those in the R22 system.

Flare processing dimensions (mm[in])

A dimension (mm)

Pipe size (mm[in])

R410A R22, R407C

ø6.35 [1/4"] 9.1 9.0

Dimension A

ø15.88 [5/8"] 19.7 19.4

ø19.05 [3/4"] 24.0 23.3

(ø19.05 pipes should have a radial thickness of 1.2 t and be made of annealed materials.) If a clutch-type flare tool is used to flare the pipes in the system using R410A, the length of the pipes must be between 1.0 and 1.5 mm. For margin adjustment, a copper pipe gauge is necessary.

6. Flare nut

The flare nut type has been changed to increase the strength. The size of some of the flare nuts have also been changed.

[4] Storage of Piping

1. Storage location

Store the pipes to be used indoors. (Warehouse at site or owner's warehouse) If they are left outdoors, dust, dirt, or moisture may infiltrate and contaminate the pipe.

2. Sealing the pipe ends

Both ends of the pipes should be sealed until just before brazing. Keep elbow pipes and T-joints in plastic bags.

The new refrigerator oil is 10 times as hygroscopic as the conventional refrigerating machine oil (such as Suniso) and, if not handled with care, could easily introduce moisture into the system. Keep moisture out of the pipes, for it will cause the oil to deteriorate and cause a compressor failure.

[5] Pipe Processing

Use a small amount of ester oil, ether oil, or alkylbenzene to coat flares and flanges.

Use a minimum amount of oil. Use only ester oil, ether oil, and alkylbenzene.

HWE0713A GB

- 7 -

[ I Read Before Servicing ]

[6] Brazing

No changes have been made in the brazing procedures. Perform brazing with special care to keep foreign objects (such as oxide scale, water, and dust) out of the refrigerant system.

Example: Inside the brazed connection

Use of oxidized solder for brazing Use of non-oxidized solder for brazing

1. Items to be strictly observed

Do not conduct refrigerant piping work outdoors if raining. Use non-oxidized solder. Use a brazing material (BCuP-3) that requires no flux when brazing between copper pipes or between a copper pipe and

copper coupling.

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

2. Reasons

The new refrigerating machine oil is 10 times as hygroscopic as the conventional oil and is more likely to cause unit failure if

water infiltrates into the system.

Flux generally contains chloride. Residual flux in the refrigerant circuit will cause sludge to form.

3. Notes

Do not use commercially available antioxidants because they may cause the pipes to corrode or refrigerating machine oil to deteriorate.

HWE0713A GB

[ I Read Before Servicing ]

[7] Air Tightness Test

No changes have been made in the detection method. Note that a refrigerant leak detector for R22 will not detect an R410A leak.

Halide torch R22 leakage detector

1. Items to be strictly observed

Pressurize the equipment with nitrogen up to the design pressure (4.15MPa[601psi]), and then judge the equipment's air tight-

ness, taking temperature variations into account.

Refrigerant R410A must be charged in its liquid state (vs. gaseous state).

2. Reasons

Oxygen, if used for an air tightness test, poses a risk of explosion. (Only use nitrogen to check air tightness.) Refrigerant R410A must be charged in its liquid state. If gaseous refrigerant in the cylinder is drawn out first, the composition

of the remaining refrigerant in the cylinder will change and become unsuitable for use.

3. Notes

Procure a leak detector that is specifically designed to detect an HFC leak. A leak detector for R22 will not detect an HFC(R410A) leak.

[8] Vacuum Drying (Evacuation)

(Photo1) 15010H (Photo2) 14010

Recommended vacuum gauge: ROBINAIR 14010 Thermistor Vacuum Gauge

1. Vacuum pump with a reverse-flow check valve (Photo1)

To prevent the vacuum pump oil from flowing into the refrigerant circuit during power OFF or power failure, use a vacuum pump with a reverse-flow check valve. A reverse-flow check valve may also be added to the vacuum pump currently in use.

2. Standard of vacuum degree (Photo 2)

Use a vacuum pump that attains 0.5Torr(65Pa) or lower degree of vacuum after 5 minutes of operation, and connect it directly to the vacuum gauge. Use a pump well-maintained with an appropriate lubricant. A poorly maintained vacuum pump may not be able to attain the desired degree of vacuum.

3. Required precision of vacuum gauge

Use a vacuum gauge that registers a vacuum degree of 5Torr(650Pa) and measures at intervals of 1Torr(130Pa). (A recommended vacuum gauge is shown in Photo2.) Do not use a commonly used gauge manifold because it cannot register a vacuum degree of 5Torr(650Pa).

4. Evacuation time

After the degree of vacuum has reached 5Torr(650Pa), evacuate for an additional 1 hour. (A thorough vacuum drying re-

moves moisture in the pipes.)

Verify that the vacuum degree has not risen by more than 1Torr(130Pa) 1hour after evacuation. A rise by less than

1Torr(130Pa) is acceptable.

If the vacuum is lost by more than 1Torr(130Pa), conduct evacuation, following the instructions in section 6. Special vacuum

drying.

5. Procedures for stopping vacuum pump

To prevent the reverse flow of vacuum pump oil, open the relief valve on the vacuum pump side, or draw in air by loosening the charge hose, and then stop the operation. The same procedures should be followed when stopping a vacuum pump with a reverse-flow check valve.

6. Special vacuum drying

When 5Torr(650Pa) or lower degree of vacuum cannot be attained after 3 hours of evacuation, it is likely that water has pen-

etrated the system or that there is a leak.

If water infiltrates the system, break the vacuum with nitrogen. Pressurize the system with nitrogen gas to

0.5kgf/cm

7. Notes

To evacuate air from the entire system Applying a vacuum through the check joints at the refrigerant service valve on the high and low pressure sides (BV1 and 2) is not enough to attain the desired vacuum pressure. Be sure to apply a vacuum through the check joints at the refrigerant service valve on the high and low pressure sides (BV1 and 2) and also through the check joints on the high and low pressure sides (CJ1 and 2).

To evacuate air only from the outdoor units Apply a vacuum through the check joints on the high and low pressure sides (CJ1, and 2).

To evacuate air from the indoor units and extension pipes Apply a vacuum through the check joints at the refrigerant service valve on the high and low pressure sides (BV1 and 2).

liquid

1. Reasons

R410A is a pseudo-azeotropic HFC blend (boiling point R32=-52°C[-62°F], R125=-49°C[-52°F]) and can almost be handled the same way as a single refrigerant, such as R22. To be safe, however, draw out the refrigerant from the cylinder in the liquid phase. If the refrigerant in the gaseous phase is drawn out, the composition of the remaining refrigerant will change and become unsuitable for use.

2. Notes

When using a cylinder with a siphon, refrigerant is charged in the liquid state without the need for turning it upside down. Check the type of the cylinder on the label before use.

[10] Remedies to be taken in case of a Refrigerant Leak

If the refrigerant leaks out, it may be replenished. The entire refrigerant does not need to be replaced. (Charge refrigerant in the liquid state.) Refer to "IX [5] Refrigerant Leak".(page 293)

[11] Characteristics of the Conventional and the New Refrigerants

1. Chemical property

As with R22, the new refrigerant (R410A) is low in toxicity and chemically stable nonflammable refrigerant. However, because the specific gravity of vapor refrigerant is greater than that of air, leaked refrigerant in a closed room will accumulate at the bottom of the room and may cause hypoxia. If exposed to an open flame, refrigerant will generate poisonous gases. Do not perform installation or service work in a confined area.

2. Refrigerant composition

R410A is a pseudo-azeotropic HFC blend and can almost be handled the same way as a single refrigerant, such as R22. To be safe, however, draw out the refrigerant from the cylinder in the liquid phase. If the refrigerant in the gaseous phase is drawn out, the composition of the remaining refrigerant will change and become unsuitable for use. If the refrigerant leaks out, it may be replenished. The entire refrigerant does not need to be replaced.

3. Pressure characteristics

The pressure in the system using R410A is 1.6 times as great as that in the system using R22.

[2] Types and Maximum allowable Length of Cables

1. Wiring work

(1) Notes

1) Have all electrical work performed by an authorized electrician according to the local regulations and instructions in this manual.

2) Install external transmission cables at least 5cm [1-31/32"] away from the power supply cable to avoid noise interference. (Do not put the control cable and power supply cable in the same conduit tube.)

3) Provide grounding for the outdoor unit as required.

4) Run the cable from the electric box of the indoor or outdoor unit in such way that the box is accessible for servicing.

5) Do not connect power supply wiring to the terminal block for transmission line. Doing so will damage the electronic components on the terminal block.

6) Use 2-core shielded cables as transmission cables. Use a separate 2-core control cable for each refrigerant system. Do not use a single multiple-core cable to connect indoor

units that belong to different refrigerant systems. The use of a multiple-core cable may result in signal transmission errors and malfunctions.

(8) Demand control

1) General outline of control

Demand control is performed by using the external signal input to the 1-2 and 1-3 pins of CN3D on the outdoor units (OC and OS). Between 2 and 8 steps of demand control is possible by setting Dip SW4-4 on the outdoor units (OC and OS).

P200-P400YHM-A and EP200-EP300YHM-A models (single-outdoor-unit system) : 2 and 4 steps shown in the rows 1 and 2 in the table above only. P450-P800YSHM-A and EP400-EP600YHM-A(1) models (two-outdoor-unit system OC+OS) : 2-8 steps shown in the rows 1, 2, 3, and 4 in the table above only.

*2 External signal is input to CN3D on the outdoor unit whose SW4-4 is set to ON. When SW4-4 is set to OFF on all outdoor units,

the signal is input to the CN3D on the OC. Outdoor units whose SW4-4 is set to ON are selectable in a single refrigerant system.

*3 If wrong sequence of steps are taken, the units may go into the Thermo-OFF (compressor stop) mode.

Ex) When switching from 100% to 50% (Incorrect) 100%ĺ0%ĺ50% The units may go into the Thermo-OFF mode. (Correct) 100%ĺ75%ĺ50%

*4 The percentage of the demand listed in the table above is an approximate value based on the compressor volume and does

not necessarily correspond with the actual capacity.

*5 Notes on using demand control in combination with the low-noise mode

To enable the low-noise mode, it is necessary to short-circuit 1-2 pin of CN3D on the outdoor unit whose SW4-4 is set to OFF. When SW4-4 is set to ON on all outdoor units, the following operations cannot be performed.

Performing 4-step demand in combination with the low-noise operation in a single-outdoor-unit system. Performing 8-step demand in combination with the low-noise operation in a two-outdoor-unit system.

[ II Restrictions ]

1) A system that requires more than 16 BC controller ports requires two or three BC controllers (main and sub), and three pipes will be used between the main and the sub BC controllers.

2) When connecting two sub BC controllers, observe the maximum allowable length in the table above.

3) When connecting two sub BC controllers, install them in parallel.

4) To connect the P100 through P140 models of indoor units, use an optional junction pipe kit (Model: CMY-R160-J) and merge the two ports before connecting them. (In that case, set DIP SW4-6 on the BC controller to ON.) It is also possible to connect the P100 through P140 models of units to a port, although the cooling performance will somewhat decrease. (In that case, set DIP SW4-6 on the BC controller to OFF.) (The factory setting for DIP SW4-6 is OFF.)

5) Do not connect the P200 or P250 models of indoor units and other models of indoor units at the same port.

6) All the units that are connected to the same ports can only be operated in the same operation mode (cooling/heating).

7) The maximum capacity of the indoor units that is connectable to the CMB-P-V-GB types of sub BC controllers is P350 or below (when two GB type controllers are connected P350 or below for both combined) . The maximum total capacity of indoor units that is connectable to the sub BC controller CMB-P1016V-HB is P350 or below. If at least one CMB-P1016V-HB unit is connected, the maximum total capacity of connectable indoor units to a system with two sub controllers is P450 or below.

[2] Control Box of the Outdoor Unit

Control box houses high-voltage parts. When opening or closing the front panel of the control box, do not let it come into contact with any of the internal components. Before inspecting the inside of the control box, turn off the power, keep the unit off for at least 10 minutes, and confirm that the voltage between FT-P and FT-N on INV Board has dropped to DC20V or less. (It takes about 10 minutes to discharge electricity after the power supply is turned off.)

2. Remote controller function selection via the ME remote controller

In the remote controller function selection mode, the settings for four types of functions can be made or changed as necessary.

1) Skip-Auto-Mode setting The automatic operation mode that is supported by some simultaneous cooling/heating type units can be made unselectable via the ME remote controller.

2) Operation mode display selection mode (Display or non-display of COOL/HEAT during automatic operation mode) When the automatic operation mode is selected, the indoor unit will automatically perform a cooling or heating operation based on the room temperature. In this case, or will appear on the remote controller display. This setting can be changed so that only will appear on the display.

3) Room temperature display selection mode (Display or non-display of room temperature) Although the suction temperature is normally displayed on the remote controller, the setting can be changed so that it will not appear on the remote controller.

4) Narrowed preset temperature range mode The default temperature ranges are 19 C to 30 C in the cooling/dry mode and 17 C to 28 C in the heating mode and 19 C to 28 C in the auto mode.

By changing these ranges (raising the lower limit for the cooling/dry mode and lowering the upper limit for the heating mode), energy can be saved.

NOTE

When making the temperature range setting on the simultaneous cooling/heating type units that supports the automatic operation mode to save on energy consumption, enable the Skip-Auto-Mode setting to make the automatic operation mode unselectable. If the automatic operation mode is selected, the energy-saving function may not work properly.

When connected to the air conditioning units that do not support the automatic operation mode, the setting for the Skip-Auto-Mode, restricted preset temperature range mode (AUTO), and operation mode display selection mode are invalid. If an attempt is made to change the preset temperature range, “LIMIT TEMP.” appears on the display.

Some models of remote controllers are not equipped with a built-in temperature sensor. Use the built-in temperature sensor

on the indoor unit instead.

When using the built-in sensor on the remote controller, install the remote controller where room temperature can be detected.
