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

properly, electric shock and fire may result.

• Securely install the 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 the it with a refrigerant different from the refrigerant (R22) 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 even 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 a special attention to the place, such as a basement, etc. where refrigeration gas can stay, since refrigeration is heavier than the air.

• The appliance is not intended for use by young children or infirm persons without supervision.

• Young children should be supervised to ensure that they do not play with the appliance.

• Never operate in open phase condition. Control box may be broken.

1.2. Before Installation

Caution:

• Do not install the unit where combustible gas may leak.

- If the gas leaks and accumulates around the unit, an explosion may result.

• Do not use the air conditioner where food, pets, plants, precision instruments, or artwork are kept.

- The quality of the food, etc. may deteriorate.

• Do not use the air conditioner in special environments.

- Oil, steam, sulfur ic smoke, etc. can significantly reduce the performance of

the air conditioner or damage its parts.

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

- The inverter equipment, private power generator, high-frequency medical

equipment, 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. Perf orm collective drainage work together with the outdoor unit, as required.

1.3. Before Installation (moved) - 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 be detected (Error cord: 4103),

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

- Some electric parts should be damaged when power is supplied under the

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 an leak circuit breaker, as required.

- If an 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 or 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 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 and damage to furniture

and other possessions.

• Be very careful about product transportation.

- Only one person should not carry the product if it weighs more than 20 kg.

- Some products use PP bands for packaging. Do not use any PP bands for 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, suspend 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.

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

result in severe damage to internal parts. K eep the po wer switch turned on during the operational season.

• Do not touch the switches with wet fingers.

- Touching a switch with wet fingers can cause electric shock.

• Do not touch the refrigerant pipes during and immediately after operation.

- During and immediately after operation, the refrigerant pipes are may be

hot and may be cold, depending on the condition of the refrigerant flowing through the refrigerant piping, compressor, and other refrigerant cycle parts. Your hands may suffer burns or frostbite if you touch the refrigerant pipes.

• Do not operate the air conditioner with the panels and guards remo ved.

- Rotating, hot, or high-voltage parts can cause injuries.

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

- Always wait at least five minutes before turning off the power. Otherwise,

SELECTION PROCEDURE

1. Model Selection (With actual examples)

First step, to select the approximate model:

Based on the cooling load and the cooling capacity listed in the capacity table, select the applicable model.

Notes:

*1. The correct WB is required since it has a serious effect on the capacity. *2. The cooling capacity decreases as the outdoor temperature increases. Therefore, the estimated highest

temperature during an air conditioning time frame is the "designed outdoor temperature". However, it is recommended that the abnormal outdoor temperature which may occur once or twice a year be excluded from the calculation to avoid selection of an excessively large capacity model.

*3. The wind pressure loss of an air duct should be calculated correctly. If a value having an excessive allowance is

used, an excessively large model will be selected. Moreover, an excessively high air flow will be induced during actual operation causing the generation of high operating sounds and carry-over of condensed water.

(Step-1) Confirmation of operation range

Confirm that the conditions given above for the model to be selected are within the operation range listed on Page 19.

(Step-2) Calculation of actual air flow, external static pressure, and fan motor input

Based on the designed air flow and external static pressure, obtain the actual air flow, actual external static pressure, and fan motor power input from the fan performance table for the model selected. For an explanation of how to use the fan performance table, see the following examples.

Example: PEH-8MYB, 50Hz

Example 1. (To operate with values near to the designed air flow and external static pressure.)

Condition : Designed air flow 70CMM

Designed external static pressure 60Pa

Calculation : The designed point is A. Therefore, duct

resistance line passing A is dotted line. Therefore, actual point is B for Hi speed operation line Actual air flow = 77CMM Actual external static pressure = 70Pa

Note: Duct resustance line is secondary curve.

Second step, to select the model:

To select the model, the following conditions must be known: (1) Total cooling load or sensible cooling load (2) Indoor conditioned temperature (WB*1, DB) (3) Designed outdoor temperature (DB)*2 (4) Designed air flow (5) Designed external static pressure (= Wind pressure loss of air duct)*3

At 26˚CDB, 19˚CWB of Indoor, Q = 21.0, SHC = 16.2, T/I = 9.2

Therefore, when air flow is 77(CMM) Q = 21.0 ✕ (1+(1.025 - 1.0) ✕ 7/10*) 21.4(kW)

SHC = 16.2 ✕ (1+(1.044 - 1.0) ✕ 7/10*) 16.7(kW) T/I = 9.2 ✕ (1+(1.009-1.0))✕ 7/10*) 9.3(kW) Note * : 7/10 = (77-70)/(80-70)

(Step-3) Calculation of net capacity

Based on the indoor conditioned temperature (WB,DB), designed outdoor temperature (DB), and the actual air flow obtained in Step-2, obtain the gross capacity from the gross capacity tables (pages 10, 11, 13, 14, 16, 17). Then, calculate the net capacity from the formula below by using the fan motor input obtained in Step-2. Net capacity (kW) = Gross capacity (kW) - Fan motor input (kW)

Example: PEH-8MYB

Condition: Cooling Indoor conditioned temp. : 26˚CDB, 19˚CWB Designed outdoor temp. : 40˚CDB Actual air flow : 77CMM Fan motor input : 0.89kW (See P.7) Calculation : The sections of the gross capacity table applicable for the above conditions are shown right.

Therfore, the net capacity is, Net total cooling capacity = 21.4 (kw) - 0.89(kW)

= 20.51 (kW)

Net sensible cooling capacity = 16.7 (kW) - 0.89 (kW)

= 15.81 (kW)

1-3.1. Fixing hanging bolts

(Use M10 hanging bolts. The bolts should be supplied in the field.) (Give site of suspension strong structure.)

Hanging structure

• Ceiling: The ceiling structure varies from one building to one another. For detailed information, consult your construction company.

1 Reinforcing the ceiling with additional members (edge beam, etc) must be re-

quired to keep the ceiling at level and to prevent the ceiling from vibrations.

2 Cut and remove the ceiling members. 3 Reinforce the ceiling members, and add other members for fixing the ceiling

boards.

For wooden construction

• Use the tie beam (for one story building) or second-floor beam (for two story building) as strength members.

• To hang the air-conditioner, use a hard square timber of more than 6 cm if the distance between beams is less than 90 cm and a hard square timber of more than 9 cm if the distance between beams is less than 180 cm.

For reinforced concrete construction

• As shown in the figure below, fix the hanging bolts, or use square timbers to fix the hanging bolts.

1-5. Refrigerant pipe and drain pipe specifications

To avoid dew drops, provide sufficient antisweating and insulating work to the refrigerant and drain pipes. When using commercially available refrigerant pipes, be sure to wind commercially available insulating material (with a heat-resisting temperature of more than 100 °C and thickness given below) onto both liquid and gas pipes. Be also sure to wind commercially available insulating material (with a form polyethylene’s specific gravity of 0.03 and thickness given below) onto all pipes which pass through rooms.

1 Select the thickness of insulating material by pipe size.

Pipe size Insulating material’s thickness

6.4 mm to 25.4 mm More than 10 mm

28.6 mm to 38.1 mm More than 15 mm

2 If the unit is used on the highest story of a building and under conditions of

high temperature and humidity, it is necessary to use pipe size and insulating material’s thickness more than those given in the table above.

3 If there are customer’s specifications, simply follow them.

1-6.1. Refrigerant piping work

This piping work must be done in accordance with the installation manuals for outdoor unit.

• For constraints on pipe length and allowable difference of elevation, refer to the outdoor unit manual.

• The method of pipe connection is brazing connection.

Cautions on refrigerant piping

s Be sure to use non-oxidative brazing for brazing to ensure that no for-

eign matter or moisture enter into the pipe.

s Provide a metal brace to support the refrigerant pipe so that no load is

imparted to the indoor unit end pipe. This metal brace should be provided 50 cm away from the indoor unit’s brazing connection.

Warning:

Do not mix anything other than the specified refrigerant (R22) into the refrigerating cycle. Mixing air may cause the refrigerating cycle to have abnormally high temperature, resulting in a burst.

Caution:

• Install the refrigerant piping for the indoor unit in accordance with the following.

1. Remove the rubber cap.

Refrigerant pipe

1-4.2. Confirming the unit’s position and fixing hang-

ing bolts

[Fig.

1-4.2.1]

A Level check

s Use the gage supplied with the panel to confirm that the unit body and

hanging bolts are positioned in place. If they are not positioned in place, it may result in dew drops due to wind leak. Be sure to check the positional relationship.

s Use a level to check that the surface indicated by A is at level. Ensure

that the hanging bolt nuts are tightened to fix the hanging bolts.

s To ensure that drain is discharged, be sure to hang the unit at level using

a level.

Caution:

Be sure to install the unit body at level.

2. Pull out the thermal insulation on the site refrigerant piping, braze the unit piping, and replace the insulation in its original position. Wrap the piping with insulating tape.

[Fig.

1-6.1.2]

A Thermal insulation B Pull out insulation C Wrap with damp cloth D Return to original position E Ensure that there is no gap F Wrap with insulating tape

Note:

• Pay strict attention when wrapping the copper piping since wrapping the piping may cause condensation instead of preventing it.

• Before brazing the refrigerant piping, always wrap the piping on the main body, and the thermal insulation piping, with damp c loths to prevent heat shrinkage and burning the thermal insulation tubing. Take care to ensure

that the flame does not come into contact with the main body itself.

Page 36

- 34 -

Caution:

• Use refrigerant piping made of C1220 (CU-DHP) phosphorus deoxidized copper as specified in the JIS H3300 “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.

• Never use existing refrigerant piping.

- The large amount of chlorine in conventional refrigerant and refrigerator oil

in the existing piping will cause the new refrigerant 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.

Additional refrigerant charge

• Take care not to allow dirt or cutting chips to enter the refrigerant pipes.

• The refrigerant pipes must be kept warm, so take particular care to insulate

between refrigerant pipes and the gas pipe located inside the indoor unit, since the gas pipe causes condensation during cooling operation.

• When connecting the refrigerant pipes, make sure that the stop valve of the outdoor unit is fully closed (as it was when shipped from the factory). After connecting all the refrigerant pipes between the indoor and outdoor units, purge air from the stop valve service port of the outdoor unit and service port of each connecting pipe. Check that there is no air leakage from any pipe connection, then fully open the stop valve of the outdoor unit. This will connect the refrigerant circuit between the indoor and outdoor units.

• The refrigerant pipes must be as short as possible.

• Flare and flange connections must be used for connection of the refrigerant

pipes.

• The indoor and outdoor units must be connected with the refrigerant pipes.

1. Ensure that the drain piping is downward (pitch of more than 20 mm/m) to the outdoor (discharge) side.

2. Ensure that any cross-wise drain piping is less than 20 m (excluding the difference of elevation). If the drain piping is long, provide metal braces to prevent it from waving. Nev er provide an y air v ent pipe. Otherwise drain may be ejected.

3. Use a hard vinyl chloride pipe VP-25 (with an external diameter of 32 mm) for drain piping.

4. Ensure that collected pipes are 10 cm lower than the unit body’s drain port .

5. Put the end of the drain piping in a position where no odor is generated.

6. Do not put the end of the drain piping in any drain where ionic gases are generated.

s Refer to the installation manual for details of the additional amount of

refrigerant for the outdoor unit.

1-7. Duct work

• In connecting duct, insert canvas duct between unit and duct.

• Use incombustible material for duct parts.

• Provide full insulation to inlet duct flange, outlet duct flange and outlet duct to

prevent condensation.

• Be sure to apply the air filter near the air inlet grille.

• Before connecting an inlet duct, remove the air filter (supplied with the unit),

then install that filter in the inlet grille.

Caution:

• Outlet duct is 850 mm or more necessary to construct.

• To connect the air conditioner main body and the duct for potential equali-

zation.

• Inlet temperature sensor when an inlet duct is installed. An inlet temperature sensor is installed on the inlet duct flange. Before connecting an inlet duct, this sensor must be removed and installed in the specified position.

1-9. Electrical wiring

Precautions on electrical wiring

Warning:

Electrical work should be done by qualified electrical engineers in accordance with “Engineering Standards For Electrical Installation” and supplied installation manuals. Special circuits should also be used. If the power circuit lacks capacity or has an installation failure, it may cause a risk of electric shock or fire.

1. Be sure to take power from the special branch circuit.

2. Be sure to install an earth leakage breaker to the power.

3. Install the unit to prevent any of the control circuit cables (remote controller, transmission cables) being in direct contact with the power cable outside the unit.

4. Ensure that there is no slack on all wire connections.

5. Some cables (power, remote controller, transmission cables) abov e the ceiling may be bitten by mouses. Use as many metal pipes as possible to insert the cables into them for protection.

6. Never connect the power cable to leads for the transmission cables. Otherwise the cables will break.

7. Be sure to connect control cables to the indoor unit, remote controller, and the outdoor unit.

8. Put the unit to the ground on the outdoor unit side.

9. Be sure to connect between the control cable terminal block of the outdoor unit and that of the indoor unit. (Cables have polarity, so make sure that they are connected according to the terminal numbers.)

10. Fix power source wiring to control box by using buffer bushing f or tensible f orce (PG connection or the like). Connect control wiring to control terminal bed throngh the knockout hole of control box using ordinary bushing.

Caution:

Be sure to put the unit to the ground on the outdoor unit side. Do not connect the earth cable to any gas pipe, water pipe, lightening r od, or telephone earth cable. Incomplete grounding may cause a risk of electric shock.

2-4.1. Installation

• 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 the units weight. Any lack of strength may the 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 the 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.

2-3. Lifting method and weight of product

Caution:

Be very careful to carry product.

- Do not have only one person to carry product if it weighs more than 20 kg.

- PP bands are used to pack some products. Do not use them as a mean for

transportation because they are dangerous.

- Do not touch heat exchanger fins with your bare hands. Otherwise you may get

a cut in your hands.

- Tear plastic packaging bag and scrap it so that children cannot play with it. Oth-

erwise plastic packaging bag may suffocate children to death.

- When carrying in outdoor unit, be sure to support it at four points. Carrying in and

lifting with 3-point support may make outdoor unit unstable, resulting in it falling.

- The angles at which ropes suspending the unit should be at least 45° and 60°.

2-5. Refrigerant piping installation

Flare connection must be applied to the indoor unit and liquid piping of the outdoor unit, whilst flange connection must be applied to the gas piping of the outdoor unit. For the branching, brazing connection must be applied.

Warning:

Always use extreme care to prevent the refrigerant gas (R22) from leaking while using fire or flame. If the refrigerant gas comes in contact with the flame from any source, such as a gas sto ve, it breaks down and generates a poisonous gas which can cause gas poisoning. Never weld in an un ventilated room. Always conduct an inspection for gas leakage after installation of the refrigerant piping has been completed.

2-5.1. Caution

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

blow it clean with a dry inert gas.

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

during installation.

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

ing radius as big as possible.

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

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

5 Never use refrigerant to perform an air purge. Always ev acuate using a vacuum

pump.

6 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.

7 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, a refrigerant leakage test has been performed and the evacuation process has been completed.

8 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.

9 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.

2-6. Additional Refrigerant Charge

2-6.1. Additional refrigerant charge

The mount of refrigerant charged in this unit is a appropriate for 5-meter long refrigerant pipes. Refer to the table below and add the corresponding amount of refrigerant if the pipes are extended. (The refrigerant is charged in the outdoor unit.)

2-6.2. Caution for piping connection/valve operation

• Conduct piping connection and valve operation accurately.

• The gas side connecting pipe is being assembled for shipment.

1 For brazing to the connecting pipe with flange, remove the connecting pipe

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

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

seal attached on the back 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 at the

shipment to prevent gas leak between flanges. As no operation can be done under this state, be sure 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.

• 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.

• Deter mine 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 gener-

ate gas leak.

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 abrupt increase. T urn the flare nut bey ond 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.

2-6.3. Airtight test, evacuation, and refrigerant charg-

ing

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.

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

Airtight test procedure

1. Nitrogen gas pressurization (1) After pressurizing to the design pressure (3.3 MPa) using nitrogen gas, let 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, spra y 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 R22 electric leak detector.

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

2 Evacuation

Evacuate with the ball valve of the outdoor unit closed and evacuate both the connection piping and the indoor unit from the service port provided on the ball valve of the outdoor unit using a vacuum pump. (Always evacuate from the service port of both the liquid pipe and the gas pipe.) After the vacuum reaches 5 Torr, continue evacuation for at least one hour or more. * Never perform air purging using refrigerant.

Note:

• Always add an appropriate amount of refrigerant. Also always seal the system with liquid refrigerant. T oo 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.)

2-6.4. 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.

Glass fiber + Steel wire Adhesive + Heat - resistant polyethylene foam + Adhesive tape Indoor Vinyl tape

Floor exposed Water-proof hemp cloth + Bronze asphalt Outdoor

Water-proof hemp cloth + Zinc plate + Oily paint

Note:

• When using polyethylene cover as covering material, asphalt roofing shall not be required.

• No heat insulation must be provided for electric wires.

Penetrations

When filling a gap with mortar, cover the penetration part with steel plate so that the insulation material will not be caved in. F or this part, use incombustible materials for both insulation and covering. (Vinyl covering should not be used.)

2-7.1. 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 Set up the outdoor unit so that the wiring for the remote controller and the M-

NET (MELANS) wiring do not produce electrical interference with the power supply cable. (Do not route them together 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.

2-7. Wiring

5 In the indoor/outdoor connection wiring, the power and signals wiring are con-

tained in the same multiconductor cable. Since the cable is polarized, be sure the connection is according to the terminal number.

6 For detailed information about the power supply cable, see the manual sup-

plied with the indoor unit.

1.1. Before test run

The test run can be carried out either from the outdoor unit or the indoor unit.

1. Checklist

• After the installation, piping setup, and wiring of the indoor and outdoor units is complete, check that refrigerant is not leaking, the power and control wires are not loose, and the poles are not reversed.

• Use a 500 V insulation resistance tester to make sure that the resistance between the power terminal and the ground is 1.0 MΩ or more. If it is less than

1.0 MΩ, do not operate the unit. * Absolutely do not touch the tester to indoor/ outdoor connection terminals S1, S2, and S3. An accident could occur.

• Make sure there is no malfunction in the outdoor unit. (If there is a malfunction, you can diagnose it using LED2 on the board.)

• Check that the ball valve is fully open on both the liquid and gas ends.

• Check the electrical power phase. If the phase is reversed, the fan may rotate

in the wrong direction or stop, or unusual sounds may be produced.

• Starting at least 12 hours before the test run, send current through the crankcase heater. (If the current is running for a shorter period of time, damage to the compressor could result.)

• For specific models requiring changing of settings for higher ceilings or selection of power supply ON/OFF capability , make proper changes ref erring to the description for Selection of Functions through Remote Controller.

After the above checks are complete, carry out the test run as indicated in the following outline.

While the room temperature display on the remote controller reads “CENTRALLY CONTROLLED”, the remote controller is disabled. Turn off the “CENTRALLY CONTROLLED” display before using the remote controller.

2 Press “TEST RUN” button twice

A The ‘TEST RUN’ indicator should light up.

3 Press button

Cooling/drying mode: Cool air should start to blow. Heating mode: Warm air should start to blow (after a while).

4 Check the outdoor unit fan for correct running

The outdoor unit features automatic capacity control to provide optimum fan speeds. The fan keeps running at a low speed to meet the current outside air condition unless it exceeds its available maximum power. Then, in actuality, the fan may stop or run in the reverse direction depending on the outside air, which does not mean malfunction.

5 Press the “ON/OFF” button to reset the test run in progress

• The test run will be automatically shut down after two hours in response to the AUTO STOP setting of two hours on the timer.

• During the test run, the room temperature display shows the indoor unit tubing temperatures.

• In the case of the test run, the OFF timer will activate, and the test run will automatically stop after two hours.

• The room temperature display section shows the control temperature for the indoor units during the test run.

• Check that all the indoor units are running properly for simultaneous twin and triple operation. Malfunctions may not be displayed even if the wiring is incorrect.

(*1) After turning ON the power, the system will go into startup mode, and the remote controller operation lamp (red) and the room temperature display section’s “H0” will flash. Also, in the case of the indoor substrata LEDs , LED 1 and LED 2 light up (when address is 0) or become dim (when address is not 0), and LED 3 flashes. In the case of the outdoor substrata LED display,

and are displayed

alternatively at 1-second intervals.

• If one of the above operations does not function correctly, the following causes should be considered, and if applicable, dealt with. (The following symptoms have been determined under test run mode. Note that “startup” in the chart means the *1 display above.)

Symptoms

Remote Controller Display Outdoor Substrate LED Display

Cause

Remote controller is displaying “H0”, and operation is not possible. After power is turned ON, “H0” is displayed for 3 mins., then error code is displayed.

Power is turned ON, and “EE” or “EF” are displayed after “H0” is displayed.

Display messages do not appear even when remote controller operation switch is turned ON (operation lamp does not light up).

Operation display appears but soon disappears even when remote controller operations are executed.

After “startup” display, “00” is displayed (correct operation). After “startup” display, error code is displayed.

After “startup” displa y , “F1” (negativ e phase) is displayed. After “startup” display, “00” or “EE” is displayed (“EE” is displayed when a test run is made). After “startup” display, “EA” (error f or number of units) or “Eb” (unit number error) is displayed. After “startup” display, “00” is displayed (correct operation). After “startup” display, “00” is displayed (correct operation). After “startup” display, “00” is displayed (correct operation).

• After power is turned ON, system startup lasts for about 2 mins., and “H0” is displayed (correct operation).

• Outdoor unit’s safeguard installation connector is open.

• Negative phase and open phase of outdoor unit’s power terminal board

(Single phase: L, N,

/triple phase: L1, L2, L3, N, )

• Incorrect connection of outdoor terminal board (Single phase: L, N, / triple phase: L1, L2, L3, N,

grounding and S1, S2, S3)

• Outdoor unit and indoor unit construction differ

• Wiring for the indoor and outdoor unit is not connected correctly. (Polarity

is wrong for S1, S2, S3)

• Remote controller transmission wire short

• There is no outdoor unit for address 0 (address is something other than

0).

• Remote controller transmission wire burnout

• After cancellation of function selection, operation is not possible for about

30 secs. (correct operation).

* Press the remote controller’s “CHECK” button twice consecutively to be able to run a self diagnosis. See the chart below for content of error code displays.

2) Outdoor unit

1) Check Items

• After installation of indoor and outdoor units, and piping and electric wiring work, check that the unit is free from leaks of refrigerant, loosened connections, and incorrect polarity.

• Check that there is no negative phase and open phase. (The F1 message for negative phase and the F2 message for open phase will flash at LED 1 on the outdoor substrate. If this happens, rewire correctly.)

• Measure the impedance between power terminals (Single phase: L, N,

triple phase: L1, L2, L3, N,

) and the ground with a 500 V Megger and check that it is 1.0 MΩ or more. Do not operate the equipment if measurement is less than 1.0 MΩ. * Never conduct this operation on the outdoor connection wiring terminals (S1, S2, S3) as this causes damage.

• When there is no error at the outdoor unit. (If there is an error at the outdoor unit, it can be evaluated at LED 1 [digital display] of the outdoor substrate.)

• The stop valves are open both the liquid and gas sides. After checking the above, execute the test run in accordance with the following.

2) Test run start and finish

• Operation from the indoor unit Execute the test run using the installation manual for the indoor unit.

• Operation from the outdoor unit Execute settings for test run start, finish and operation mode (cooling, heating) using the DIP switch SW 4 on the outdoor substrate.

1 Set the operation mode (cooling, heating) using SW 4-2 2 Turn ON SW 4-1, The operation mode for SW 4-2 will be adhered to, and

the test run will commence

3 Turn OFF SW 4-1 to finish the test run

• There may be a faint knocking noise emitted from the proximity of the fan during the test run. This is torque fluctuation occurring due to control of fan revolutions. There is no problem with the product.

Note: The SW 4-2 operation mode cannot be changed during the test run. (T o change test run mode, stop the equipment with SW 4-1, change the operation mode, then restart test run with SW 4-1.)

• If the 2-hour timer is set, the test run will stop automatically after 2 hours.

• During the test run, the room temperature display on the indoor unit will indi-

cate the temperature of the indoor unit piping.

Potential problems other than those diagnosed for the remote controller.

(1) Single transmission not possible if error display 2 (“E3”) flashes.

There is “noise” on the transmission line, or damage of other remote controllers for the indoor units can be considered. Check the transmission path and other controllers.

(2) Data error has occurred when error display three shows “ERC” and number of

data errors. Number of generated data errors (maximum 66 errors). The number of generated data errors stands for the difference in the number of bits of transmitted data from the remote controller and the actual number of bits that were transmitted along the transmission path. If this error occurs , “noise”, etc., is interfering with the transmission data. Check the transmission path.

(1) Protection functions

1) The main protection devices for the outdoor unit are:

1 High pressure protection (63H1) 2 Compressor overcurrent protection (51C) 3 Liquid temp thermistor trouble (TH1) 4 Discharge temperature protection (TH2

135 °C)

5 Discharge temp thermistor trouble (TH2) 6 Condenser/evaporater temp thermistor trouble (TH3)

2) When tripping of a detection device is sensed, the check mode is entered and the compressor is stopped. (After 3 minutes, the compressor restarts.) Thereafter, the compressor is stopped when the specified number of check modes or greater is sensed within the check time.

3) Check mode is released by stopping operation, changing the operation mode, or check mode time up. A check mode is also released by stopping of operation by remote controller.

4) Detected check mode history (newest) and abnormality history (last 2 times) are memorized and are displayed on the segment by circuit board DIP switch setting. The operation mode when the newest abnormality was generated, the thermistor temperature (TH1,2,3), and the thermostat ON time can also be displayed.

(2) Compressor, 4-way valve, and crankcase heater control

1) Deter mines the operation mode and operates the compressor based on the indoor/outdoor communication or MNET communication data.

2) Compressor control has a function which prevents the compressor from restarting within 3 minutes.

3) The 4-way valve is always ON during heating (except during defrosting). In other modes, it is OFF. However, when the operation mode was changed from heating to stop, the 4-w ay valv e is turned off 10 minutes after the compressor was stopped.

4) While the compressor is stopped, the crankcase heater remains ON. (OFF while the compressor is operating.)

5) When the operation mode is changed while the compressor is operating, the compressor stops and 3 minutes later restarts in the new mode.

(3) Fan control

Controls the fan speed based on the piping temperature (TH1) to perform cooling at low outdoor temperatures and heating at high outdoor temperatures.

1) Control at cooling

1 When the compressor stops, the fan stops (fan output = 0 %). 2

longer, the piping temperature ( TH1) determines the fan output.

When TH

25 °C Fan output = 100 %

When TH < 25 °C Fan output = 60 %

3 When the compressor is restarted within 30 minutes after it has been stopped, the fan step before the compres-

sor was stopped is selected. Ho w ever, when the fan output was under 30% when the fan was stopped, 30 % is selected.

4 When the mode was changed from heating to cooling, the fan step conforms to item 2. 5 Two minutes after the f an is started, the fan step (number of units) is controlled every 30 seconds based on the

piping temperature (TH1).

6 When TH1 reaches 50 °C or higher, or when the control high pressure switch (63H2) tripped, the fan output

becomes 100 %.

7 Fan output while the compressor is operating is within the 20 % to 100 % range.

• FAN step The following expression determines the next fan step count nj+1: nj+1 = nj+∆nj nj: Current fan step, ∆nj: Displacement step amount nj control

• If nj+1

• If TH1

2) Control at heating

1 When the compressor is stopped and during defrosting, the fan is stopped. 2 When the power is turned on, or when the compressor is restarted after being stopped for 30 minutes or longer ,

the piping temperature (TH1) determines the fan step.

TH1 > 8 °C Fan output = 60 % TH1

8 °C Fan output = 100 %

3 When the compressor is restarted within 30 minutes, the fan step is the step before the compressor w as stopped. 4 When the mode is changed from cooling to heating, the fan step conforms to item 2. 5 When returning from defrosting, the fan step is the step before defrosting. 6 Two minutes after the fan was restarted, the fan step is controlled every 30 seconds based on the piping tem-

perature (TH1).

7 When TH1 is –5 °C or lower, the fan output is made 100%.

• FAN step

The following expression determines the next fan step count nj+1: nj+1 = nj+∆nj nj: Current fan step, ∆nj: Displacement step amount nj control

• If nj+1

• If TH1 < –5 °C nj+1 = 100 %

FAN ∆nj Outputs are all %.

(4) Defrosting control

1) When the following conditions are satisfied, defrosting starts: 1 When the integrated compressor operation time has exceeded T

1 (initial setting 50 minutes) and the piping

temperature (TH1) is below –10 °C

2 When the integrated compressor operation time has exceeded 30 minutes and the piping differential tempera-

ture is ∆TH1

8, TH1

–10 °C

Piping differential temperature ∆TH1 = TH10 – TH1

2) The defrosting prohibit time T

1 is set as following based on the defrosting time T2:

Note: T

1 is reset at the end of defrosting, or by cooling ON command.

Note: When the compressor was stopped during defrosting, T1 = 20 minutes is set to recognize the stop as defrost-

ing end.

3) During defrosting, all the outdoor fans are stopped and the bypass solenoid v alve (SV1) is turned ON and the 4-wa y valve (21S4) is turned OFF.

4) When the following conditions are satisfied, defrosting ends: 1 T

(5) Bypass solenoid valve control (SV1)

1) Control at cooling

1 While the compressor is stopped, the solenoid valve is OFF. 2 When the power is turned on, or when the compressor is restarted after it has been stopped for 30 minutes or

longer, if the liquid temperature (TH1) in 25 °C or higher then the solenoid valve turns ON for 2 minutes.

3 When the mode is changed from heating to cooling, solenoid valve operation conforms to item 2.

2) Control at heating

1 While the compressor is stopped, the solenoid valve is OFF. 2 When the power is turned on, or the compressor is restarted after it has been stopped for 30 minutes or longer ,

the solenoid valve turns ON for 2 minutes.

3 When the mode is changed from cooling to heating, the solenoid valve turns ON for 2 minutes at starting. 4 When the control pressure switch (63H2) trips, the solenoid valve turns ON. 5 If 63H2 resets 15 minutes after tripping, the solenoid valve turns OFF. 6 During defrosting, the solenoid valve turns ON.

(6) Service functions

1) Abnormality history clear 1 When DIP SW1-2 is turned ON while the compressor is operating or stopped, the abnormality history is cleared.

[6] Emergency operation

1) When the following check displays occur at the outdoor unit, or when the wired remote controller or indoor unit microcomputer fails, if there are no other def ects, emergency operation is possible by shorting the connector (CN31) on the outdoor controller board.

• Abnormalities that allow emergency operation

2) Check items and precautions when performing emergency operation 1 In addition to the abnor malities above, check the outdoor unit for any abnormalities. (When there is an abnor-

mality other than the above, emergency operation is impossible.)

2 Check the operating range. (For U4 display)

Since the outdoor fan always oper ates at full speed at emergency oper ation, do not oper ate the air conditioner outside the range shown below.

Operation outside this range may cause compressor trouble.

3 When performing emergency operation, set the outdoor unit after setting the emergency operation switch (SWE)

on the indoor controller board. For the indoor emergency operation method, refer to the indoor unit wiring diagram.

4 A power failure causes emergency operation to become continuous operation. ON/OFF, temperature adjust-

ment and other operations cannot be performed from the remote controller. (When a PEH-P8YE or P10YE indoor unit is connected, check that the special indoor unit power is turned on, then start emergency operation.)

5 Since cool air is discharged from the indoor unit, when the outdoor unit star ts the defrosting operation during

heating emergency operation, do not operate the air conditioner for a long time.

6 You can perform cooling emergency operation up to 10 hours. The indoor unit heat exchanger may freeze. 7 At the end of emergency operation, always return the switch settings, etc. to their original state.

3) Emergency operation contents

1 The operation mode operates according to the contents set (cooling or heating) by SW4-2. 2 The fan operation condition is always 100 % operation. 3 The operation mode display flashes every other second.
