Be sure to provide designated grounding work to heat source unit.

Give some allowance to wiring for electrical part box of indoor and heat source unit, because the box is sometimes removed at the time of service work.

Never connect 100V, 208~230V, 460V power source to terminal block of transmission . If connected,electrical parts will be burnt out.

1. Use dedicated power supplies for the heat source unit and indoor unit. Ensure OC and OS are wired individually.

2. Bear in mind ambient conditions (ambient temperature,direct sunlight, rain water,etc.) when proceeding with the wiring and connections.

3. The wire size is the minimum value for metal conduit wiring. If the voltage drops, use a wire that is one rank thicker in diameter.

Make sure the power-supply voltage does not drop more than 10%.

4. Specific wiring requirements should adhere to the wiring regulations of the region.

5. Power supply cords of parts of appliances for heat source use shall not be lighter than polychloroprene sheathed flexible cord

(design 245 IEC57). For example, use wiring such as YZW.

6. A switch with at least 3 mm [1/8 in.] contact separation in each pole shall be provided by the Air Conditioner installer.

• Be sure to use specified wires for connections and ensure no external force is imparted to terminal connections. If connections are not fixed firmly, heating or fire may result.

• Be sure to use the appropriate type of overcurrent protection switch. Note that generated overcurrent may include some amount of

• Some installation sites may require attachment of an earth leakage breaker for the inverter. If no earth leakage breaker is installed, there is a danger of electric shock.

• Do not use anything other than a breaker and fuse with the correct capacity. Using a fuse or wire of too large capacity may cause malfunction or fire.

Note:

1 The transmission cable is not-polarity double-wire.

2 Symbol means a screw terminal for wiring.

3 The shield wire of transmission cable should be connected to the grounding terminal at

Heat source unit. All shield wire of M-Net transmission cable among Indoor units should be connected to the S terminal at Indoor unit or all shield wire should be connected together.

The broken line at the scheme means shield wire.

4 When the Heat source unit connected with system controller, power-supply to TB7 of the heat source unit(s) is needed. The connector change from CN41 to CN40 at one of the heat source units will enable the heat source unit to supply power to TB7, or an extra power supplying unit PAC-SC51KUA should be used. The transmission cable (above 1.25mm

2 , shielded, CVVS/CPEVS/MVVS) among Heat source units and system controllers is called central control transmission cable. The shield wire of the central control transmission cable must be grounded at the Heat source unit whose CN41 is changed to CN40.

5 MA R/C transmission cable (0.3-1.25mm

2 ) must be less than 200m in length, while ME

R/C transmission cable (0.3-1.25mm

2 ) must be less than 10m in length. But transmission cable to the ME R/C can be extend using a M-NET cable (>=1.25mm

2 ) when the length is counted in the M-Net length. Both Compact MA and ME R/C transmission cables size

0.75~1.25mm

2 in thickness.

6 MA remote controller and ME remote controller should not be grouped together.

7 If using 1 or 2 (main/sub) MA remote controller to control more than 1 Indoor unit, use MA transmission cable to connect all the TB15 terminals of the Indoor units. It is called

"Grouping".

If using 1 or 2 (main/sub) ME remote controller control more than 1 indoor unit, set address to Indoor unit and ME remote controller. For the method, refer to 2-4. "Address

Setting".

8 Indoor board consumes power from TB3. The power balance should be considered according to System Design 2-3 "System configuration restrictions".

9 If Transmission booster is needed, be sure to connect the shield wires to the both sides to the booster.

10 The critical current for choosing power source equipment is approximate

1.4 times of total rated current of the Heat source unit(s) or Indoor unit(s).

11 Numbers shown with ( ) indicates a diameter of the compact remote controller.

12 When System controller (SC) is connected to the system, turn the SW2-1 on.

13 The phases of electricity power must be confirmed to be right used. Phase-reverse, or

phase-missing could break the controllers.

Note:

1 The transmission cable is not-polarity double-wire.

2 Symbol means a screw terminal for wiring.

3 The shield wire of transmission cable should be connected to the grounding terminal at

Heat source unit. All shield wire of M-Net transmission cable among Indoor units should be connected to the S terminal at Indoor unit or all shield wire should be connected together.

The broken line at the scheme means shield wire.

4 When the Heat source unit connected with system controller, power-supply to TB7 of the heat source unit(s) is needed. The connector change from CN41 to CN40 at one of the heat source units will enable the heat source unit to supply power to TB7, or an extra power supplying unit PAC-SC51KUA should be used. The transmission cable (above 1.25mm

2 , shielded, CVVS/CPEVS/MVVS) among Heat source units and system controllers is called central control transmission cable. The shield wire of the central control transmission cable must be grounded at the Heat source unit whose CN41 is changed to CN40.

5 MA R/C transmission cable (0.3-1.25mm

2 ) must be less than 200m in length, while ME

R/C transmission cable (0.3-1.25mm

2 ) must be less than 10m in length. But transmission cable to the ME R/C can be extend using a M-NET cable (>=1.25mm

0.75~1.25mm

2 ) when the length is counted in the M-Net length. Both Compact MA and ME R/C transmission cables size

2 in thickness.

6 MA remote controller and ME remote controller should not be grouped together.

7 If using 1 or 2 (main/sub) MA remote controller to control more than 1 Indoor unit, use MA transmission cable to connect all the TB15 terminals of the Indoor units. It is called

"Grouping".

If using 1 or 2 (main/sub) ME remote controller control more than 1 indoor unit, set address to Indoor unit and ME remote controller. For the method, refer to 2-4. "Address

Setting".

8 Indoor board consumes power from TB3. The power balance should be considered according to System Design 2-3 "System configuration restrictions".

9 If Transmission booster is needed, be sure to connect the shield wires to the both sides to the booster.

10 The critical current for choosing power source equipment is approximate

.

11 Numbers shown with ( ) indicates a diameter of the compact remote controller.

12 When System controller (SC) is connected to the system, turn the SW2-1 on.

13. The phases of electricity power must be confirmed to be right used. Phase-reverse, or

phase-missing could break the controllers.

2-3. System Configuration Restrictions

2-3-1. Common restrictions for the CITY MULTI system

For each Heat source unit, the maximum connectable quantity of Indoor unit is specified at its Specifications table.

A) 1 Group of Indoor units can have 1-16 Indoor units;

B) Maximum 2 remote controllers for 1 Group;

C) 1 LOSSNAY unit can interlock maximum 16 Indoor units; 1 Indoor unit can interlock only 1 LOSSNAY unit.

D) Maximum 3 System controllers are connectable when connecting to TB3 of the Heat source unit.

E) Maximum 3 System controllers are connectable when connecting to TB7 of the Heat source unit, if the transmission power is supplied by the Heat source unit.

F) 4 System controllers or more are connectable when connecting to TB7 of the Heat source unit, if the transmission power is supplied by the power supply unit PAC-SC51KUA. Details refer to 2-3-3-C.

*System controller connected as described in D) and E) would have a risk that the failure of connected Heat source

unit would stop power supply to the System controller.

2-3-2. Ensuring proper communication power for M-NET

In order to ensure proper communication among Heat source unit, Indoor unit, LOSSNAY and Controllers, the transmission power situation for the M-NET should be observed. In some cases, Transmission booster should be used. Taking the power consumption index of Indoor unit sized P06-P54 as 1, the equivalent power consumption index and supply capability index of others are listed at Table 2-3-1 and Table 2-3-2.

With the equivalent power consumption values in Table 2-3-1 and Table 2-3-2, PAC-SF46EPA can be designed into the airconditioner system to ensure proper system communication according to 2-3-2-A, B, C.

2-3-2-A) Firstly, count from TB3 at TB3 side the total quantity of Indoor units and ME remote controller, Timers and System controllers.If the total quantity reaches 40, a PAC-SF46EPA should be set.In this case, Indoor unit sized P72, 96 is counted as 7 Indoor units, but MA remote controller(s), LOSSNAY is NOT counted.

2-3-2-B) Secondly, count from TB7 side to TB3 side the total transmission power consumption index. If the total power consumption reaches 32, a PAC-SF46EPA should be set.Yet, if a PAC-SC51KUA is used to supply power at TB7 side, count from index TB3 side only.

2-3-2-C) Thirdly, count from TB7 at TB7 side the total transmission power consumption index, If the total power consumption reaches

6, a PAC-SF46EPA should be set.

2-3-3. Ensuring proper power supply to System controller

The power to System controller (excluding LMAP03-U) is supplied via M-NET transmission line. M-NET transmission line at TB7 side is called Central control transmission line while one at TB3 side is called Indoor-Heat source transmission line. There are 3 ways to supply power to the System controller .

A) Connecting to TB3 of the Heat source unit and receiving power from the Heat source unit.

B) Connecting to TB7 of the Heat source unit and receiving power from the Heat source unit.

C) Connecting to TB7 of the Heat source unit but receiving power from power supply unit PAC-SC51KUA.

2-3-3-A. When connecting to TB3 of the

Heat source

unit and receiving power from the

Heat source

unit.

Maximum 3 System controllers can be connected to TB3.

If there is more than 1 Heat source unit, it is necessary to replace power supply switch connector CN41 with CN40 on one Heat source unit.

When using PAC-SC51KUA to supply transmission power, the power supply connector CN41 on the Heat source units should be kept as it is. It is also a factory setting.

1 PAC-SC51KUA supports maximum 1 AG-150A unit due to the limited power DC 24V at its TB3.

However, 1 PAC-SC51KUA supplies transmission power at its TB2 equal to 5 Indoor units, which is referable at

Table 2-3-2.

If PZ-52SF, Timers, System controller, ON/OFF controller connected to TB7 consume transmission power more than 5 (Indoor units), Transmission booster

PAC-SF46EPA is needed. PAC-SF46EPA supplies transmission power equal to 25 Indoor units.

CAUTION

System controller

AG-150A/GB-50A/GB-50ADA/GB-24A/TC-24A is recommended to connect to TB7 because these controllers perform back-up to a number of data.

In an air conditioner system has more than 1 Heat source units, AG-150A/GB-50A/GB-50ADA/GB-24A/TC-24A receiving transmission power at TB3 or TB7 on one of the Heat source units would have a risk that the connected Heat source unit failure would stop power supply to AG-150A/GB-50A/GB-50ADA/

GB-24A/TC-24A, and disrupt the whole system. When applying apportioned electric power function, AG-150A/GB-50A/GB-24A/TC-24A is necessary to connected to TB7 and has its own power supply unit PAC-SC51KUA.* *Power supply unit PAC-SC51KUA is for AG-150A.


WR2SD-13


2-3-4. Power supply to LM adapter LMAP03U

1-phase 208-230V AC power supply is needed.

The power supply unit is not necessary when connecting only the LMAP03U. Yet, make sure to change the power supply changeover connector CN41 to CN40 on the LM adapter.

2-3-5. Power supply to expansion controller

1-phase 100-240VAC power supply is needed.

The power supply unit PAC-SC51KUA is not necessary.

The expansion controller supplies power through TB3, which equals 6 indoor units. (refer to Table 2-3-2)

2-3-6. Power supply to BM ADAPTER

1-phase 100-240VAC power supply is needed.

The power supply unit PAC-SC51KUA is not necessary when only BM ADAPTER is connected.

Yet, make sure to move the power jumper from CN41 to CN40 on the BM ADAPTER.



2-4. Address Setting

2-4-1. Switch operation

In order to constitute CITY MULTI in a complete system, switch operation for setting the unit address No. and connection No. is required.

À Address No. of heat source unit, indoor unit and remote controller.

The address No. is set at the address setting board.

In the case of WR2 system, it is necessary to set the same No. at the branch No. switch of indoor unit as that of the BC controller connected. (When connecting two or more branches, use the lowest branch No.)

Note

Use the most recent address within the same group of indoor units. Make the indoor units address connected to the BC controller (Sub) larger than the indoor units address connected to the BC controller (Main).

If applicable, set the sub BC controllers in an PQRY system in the following order:

(1) Indoor unit to be connected to the BC controller (Main)

(2) Indoor unit to be connected to the BC controller (No.1 Sub)


Set the address so that (1)<(2)<(3)

The smallest address of indoor unit in same refrigerant system + 50

Assign sequential address numbers to the heat source units in one refrigerant circuit system. OC and OS are automatically detected. (Note 2)

Please reset one of them to an address between 51 and 99 when two addresses overlap.

The address automatically becomes "100" if it is set as "01~ 50"

The address of heat source unit + 1

Please reset one of them to an address between 51 and 99 when two addresses overlap.

The address automatically becomes "100" if it is set as "01~ 50"

2-4-3. System examples

Factory setting

Original switch setting of the heat sources, indoors, controllers and LMAP at shipment is as follows.

• Heat source unit

• Indoor unit

• BC controller

• ME remote controller

• LMAP

: Address: 00, CN41: U (Jumper), DipSW2-1: OFF

: Address: 00

: Address: 00

: Address: 101

: Address: 247, CN41: U (Jumper), DipSW1-2: OFF

Setting at the site

• DipSW2-1(Heat source) : When the System Controller is used, all the Dip SW2-1 at the heat source units should be

set to "ON". * Dip SW2-1 remains OFF when only LMAP03U is used.

• DipSW1-2(LMAP)

• CN40/CN41

: When the LMAP is used together with System Controller, DipSW1-2 at the LMAP

should be set to "ON".

: Change jumper from CN41 to CN 40 at heat source control board will activate central

transmission power supply to TB7;

(Change jumper at only one heat source unit when activating the transmission power supply

without using a power supply unit.)

Change jumper from CN41 to CN 40 at LMAP will activate transmission power supply to LMAP

itself;

Power supply unit is recommended to use for a system having more than 1 heat source unit,

because the central transmission power supply from TB7 of one of heat source units is risking

that the heat source unit failure may let down the whole central control system.

3. PIPING DESIGN

3-1. R410 Piping Material

Refrigerant pipe for CITY MULTI shall be made of phosphorus deoxidized copper, and has two types.

A. Type-O : Soft copper pipe (annealed copper pipe), can be easily bent with human's hand.

B. Type-1/2H pipe : Hard copper pipe (Straight pipe), being stronger than Type-O pipe of the same radical thickness.

The maximum operation pressure of R410A air conditioner is 4.30 MPa [623psi] . The refrigerant piping should ensure the safety under the maximum operation pressure. MITSUBISHI ELECTRIC recommends pipe size as Table 3-1, or You shall follow the local industrial standard. Pipes of radical thickness 0.7mm or less shall not be used.

3-2. Piping Design

3-2-1. IF 16 ports or less are in use, I.e., if only one BC controller is in use with no sub BC controller.r

Note1. PQRY systems do not require headers.

Note2. Indoor units sized P72-P96 should be connected to a BC controller using the Y-shaped

CMY-R160-J joint adapter. These indoor units cannot use the same BC controller ports as other units. (They must use their own individual BC controller port.)

Note3. As bends cause pressure loss on transportation of refrigerant, the fewer bends in the system, the better it is. Piping length needs to factor in the actual length and equivalent length in which the bends are counted.

Note4. Indoor units connected to the BC controller sharing one port cannot operate separately in heating and cooling modes simultaneously; i.e., they must function in either heating or cooling in tandem.

Note5. Indoor unit capacities are included in the model name. For example, PEFY-P24NMSU-E has a capacity of 24,000 BTUs.

Note6. Total “downstream indoor capacity” is the total of all the indoor units connected downstream. For example,

PEFY-P24NMSU-E + PEFY-P12NMSU-E: Total Indoor Unit Capacity = P24 + P12 = P36.

1. Insulation installation

With City Multi WY/ WR2 Series piping, as long as the temperature range of the circulating water is kept to average temperatures year-round

(29.4°C[85°F] in the summer, 21.1°C[70°F] in the winter), there is no need to insulate or otherwise protect indoor piping from exposure. You should use insulation in the following situations:

• Any heat source piping.

• Indoor piping in cold-weather regions where frozen pipes are a problem.

• When air coming from the outside causes condensation to form on piping.

• Any drainage piping.

2. Water processing and water quality control

To preserve water quality, use the closed type of cooling tower for WY/

WR2. When the circulating water quality is poor, the water heat exchanger can develop scales, leading to a reduction in heat-exchange power and possible corrosion of the heat exchanger. Please pay careful attention to water processing and water quality control when installing the water circulation system.

• Removal of foreign objects or impurities within the pipes.

During installation, be careful that foreign objects, such as welding fragments, sealant particles, or rust, do not enter the pipes.

• Water Quality Processing

Depending on the quality of the cold-temperature water used in the air conditioner, the copper piping of the heat exchanger may become corroded. We recommend regular water quality processing.

Cold water circulation systems using open heat storage tanks are particularly prone to corrosion.

When using an open-type heat storage tank, install a water-to-water heat exchanger, and use a closed-loop circuit on the air conditioner side. If a water supply tank is installed, keep contact with air to a minimum, and keep the level of dissolved oxygen in the water no higher than 1mg/ .

Reference : Guideline of Water Quality for Refrigeration and Air Conditioning

Equipment. (JRA GL02E-1994)

Please consult with a water quality control specialist about water quality control methods and water quality calculations before using anti-corrosive solutions for water quality management.

When replacing a previously installed air conditioning device (even when only the heat exchanger is being replaced), first conduct a water quality analysis and check for possible corrosion.

Corrosion can occur in cold-water systems even if there has been no prior signs of corrosion. If the water quality level has dropped, please adjust water quality sufficiently before replacing the unit.


5. CAUTIONS

The installer and/or air conditioning system specialist shall secure safety against refrigerant leakage according to local regulations or standards.

The following standard may be applicable if no local regulation or standard is available.

5-1. Refrigerant Properties

R410A refrigerant is harmless and incombustible. The R410A is heavier than the indoor air in density. Leakage of the refrigerant in a room has possibility to lead to a hypoxia situation. Therefore, the Critial concentration specified below shall not be exceeded even if the leakage happens.

Critical concentration

Critical concentration hereby is the refrigerant concentration in which no human body would be hurt if immediate measures can be taken when refrigerant leakage happens.

Critical concentration of R410A: 0.30kg/m 3

(The weight of refrigeration gas per 1 m 3 air conditioning space.);

The Critical concentration is subject to ISO5149, EN378-1.

For the CITY MULTI system, the concentration of refrigerant leaked should not have a chance to exceed the Critical concentration in any situntion.

5-2. Confirm the Critical Concentration and Perform Countermeasures

The maximum refrigerant leakage concentration (Rmax) is defined as the result of the possible maximum refrigerant weight (Wmax) leaked into a room divided by its room capacity (V). It is referable to Fig. 5-1. The refrigerant of Heat source unit here includes its original charge and additional charge at the site.

The additional charge is calculated according to the refrigerant charging calculation of each kind of Heat source unit, and shall not be over charged at the site. Procedure 5-2-1~3 tells how to confirm maximum refrigerant leakage concentration (Rmax) and how to take countermeasures against a possible leakage.

W2: Refrigerant weight of Heat source unit No.2

Fig. 5-1 The maximum refrigerant leakage concentration

5-2-1.Find the room capacity (V),

If a room having total opening area more than 0.15% of the floor area at a low position with another room/space, the two rooms/space are considered as one. The total space shall be added up.

5-2-2.Find the possible maximum leakage (Wmax) in the room. If a room has Indoor unit(s) from more than 1 Heat source unit, add up the refrigerant of the Heat source units.

5-2-3.Divide (Wmax) by (V) to get the maximum refrigerant leakage concentration (Rmax).

5-2-4.Find if there is any room in which the maximum refrigerant leakage concentration (Rmax) is over 0.30kg/m 3 .

If no, then the CITY MULTI is safe against refrigerant leakage.

If yes, following countermeasure is recommended to do at site.

Countermeasure 1: Let-out (making V bigger)

Design an opening of more than 0.15% of the floor area at a low position of the wall to let out the refrigerant whenever leaked.

e.g. make the upper and lower seams of door big enough.

Countermeasure 2: Smaller total charge (making Wmax smaller) e.g. Avoid connecting more than 1 Heat source unit to one room.

e.g. Using smaller model size but more Heat source units. e.g. Shorten the refrigerant piping as much as possible.

Countermeasure 3: Fresh air in from the ceiling (Ventilation)

As the density of the refrigerant is bigger than that of the air . Fresh air supply from the ceiling is better than air exhausting from the ceiling.

Fresh air supply solution refers to Fig. 5-2~4.

Note 1. Countermeasure 3 should be done in a proper way in which the fresh air supply shall be on whenever the leakage happens.

Note 2. In principle, MITSUBISHI ELECTRIC requires proper piping design, installation and air-tight testing after installation to avoid leakage happening.

In the area should earthquake happen, anti-vibration measures should be fully considered.

The piping should consider the extension due to the temperature variation.
