Standard type
Note 1. If units are operated for a long time at the dew point temperature of 23˚C [73˚F] or more, condensate may collect and drip from the indoor units. If the units are operated under such conditions, cover the entire surface of all indoor units with insulating materials with a thickness of between 0 and 20 mm [13/16 in.] to prevent condensate from collecting.
Cooling Heating (Note 2)
Indoor temperature Wet-bulb temperature15~35˚C [50~95˚F]

(1) Notes on using the Fresh Air Intake type units
1Fresh air intake type indoor units supply pretreated outside air into the room. This type of units are not designed to handle internal thermal load. Use other types of air conditioning units (e.g., CITY MULTI system) that are capable of handling internal thermal load in combination with the Fresh Air Intake type units.
2The control mode is selectable between room temperature control and supply air temperature control. The default mode is room temperature control. Install the supplied thermistor in a location that allows the sensor to measure the representative room temperature.
·Fresh air intake type units are intended to be used in an environment at a temperature of 0˚CDB [32˚FDB] or above. If the units are operated in the fan mode at the temperature below 0˚C[32˚F], condensation may form on the panel under certain conditions. Use caution so that the condensation will not drip on appliances around the unit.·The unit may be forced to operate in the heating mode to prevent cold draft when the return air temperature (outside air temperature sensor reading) reaches 5˚C[41˚F] or below. The fan will stop during the defrost cycle and when there is a problem with the entire refrigerant systems. The fan can be set to operate in the conditions above by making certain switch settings if a sudden supply of cold air into the room during the heating season will not be a problem.·Note that untreated outside air may be delivered directly into the room upon Thermo-OFF. Use extra caution when the outside temperature is low. Direct exposure to outdoor air may have an adverse effect on health or cause food spoilage. ·Fresh air intake type units are not equipped with a dehumidifying function. Take appropriate measures to keep condensation from forming on the supply air grill and other parts that are subject to condensation. Line the supply and return air ducts with insulation to prevent condensation.
Common items
Room temperature control (factory setting)
·Install the thermistor that is supplied with the indoor unit. Check that Switch 7-2 is set to OFF.·Install the thermistor in a location that allows the sensor to measure the representative room temperature.·The unit will go into the forced Thermo-OFF mode when the return air dry bulb temperature (outside air temperature sensor reading) is 21˚C[70˚F] or below during cooling OR 20˚C[68˚F] or above during heating.·The settable temperature range on the remote controller is as follows: Cooling 19 - 30˚C[66 - 86˚F]; Heating 17-28˚C[63 - 82˚F].·Indoor temperature and humidity can fluctuate greatly depending on the outside air load.
Supply air temperature control
·Connect the connector of the supply air temperature sensor that is built in on the indoor unit to the control board. Turn Switch 7-2 to ON.·The unit will go into the forced Thermo-OFF mode and operate in the Fan mode when the return air dry bulb temperature (outside air temperature sensor reading) is 14˚C[57˚F] or below during cooling OR 28˚C[82˚F] or above during heating.·Supply air temperature may fluctuate, depending on the temperature/humidity of the outside air or on other operating conditions. Units may go in and out of the Thermo-ON/OFF mode when the following conditions are met: The difference between the outside temperature and the preset temperature is less than approximately 6˚C[43˚F] due to excess capacity. They may change depending on the air flow rate and preset temperature.·Supply air temperature normally appears on the remote controller. When the unit operation is not stable, this temperature may blink on the display and can be mistakenly interpreted as an error. If this is a problem, change the setting to suppress the temperature display. Refer to the section "How to use the remote controller" in the Instructions Manual for how to make the setting.·The settable temperature range on the remote controller is as follows: Cooling 14 - 30˚C[57 - 86˚F]; Heating 17-28˚C[63 - 82˚F].·Depending on the air conditioning load, outside temperature, and due to the activation of protection functions, the desired preset temperature may not always be achieved.

4Fan controlThe unit may be forced to operate in the heating mode to prevent cold draft when the return air temperature (outside air temperature sensor reading) reaches 5˚C[41˚F] or below. At the time of factory shipment, fan setting is made so that the fan will stop during the defrost cycle and when there is a problem with the entire refrigerant systems.See below for switch settings and unit operation.
5Sample operation patterns (supply air temperature control)The unit will follow the operation control pattern below at the nominal air flow rate and the preset temperature of 22˚C[72˚F]. Use it only as a guide. The range changes with the air flow rate and preset temperature.

Notes
When the return air temperature reaches 5˚C[41˚F] or below, the unit will be forced to operate in the heating mode to prevent cold draft regardless of the actual operation mode setting. If the return air temperature reaches 6˚C[43˚F] or above, the units will resume operation in the selected mode. The fan will stop when there is an error, regardless of the outside temperature.
OperationOFF ON
*Operating the fan during the defrost cycle can cause cold outside air to be delivered into the room, and it can also delay normal unit operation to be resumed after the defrost cycle is completed, both of which can greatly decrease the room temperature.

Note1. Use two V-belts for P750 indoor unit.
The fan characteristic curve shows the internal resistance is 100 Pa when the air flow rate is 250m3/min.Total static pressure = internal resistance + external static pressure =100 Pa + 600 Pa =700 PaRead the intersection point of the total static pressure 700 Pa and the air flow rate 250m3/min in the fan characteristic curve. You will see that the set of pulleys No.4 is suitable under the condition.The left table shows the details of appropriate pulley combinations. Motor pulley : ø212-B-2-38 Fan pulley : ø300-B-2-32 V-belt : B57/1448 mm
Note 1. When replacing the motor on site, reset the thermal relay accordingly.Note 2. Mitsubishi Electric shall not be held responsible for the pulley or motor modified on site.

(4) Weather countermeasure
In cold and/or snowy areas, sufficient countermeasures to wind and snow damages should be taken foroperating unit in normal and good condition in winter time. Even in the other areas, full consideration isrequired for installation of unit in order to prevent abnormal operations caused by wind or snow. Whenrain and snow directly fall on unit in the case of air-conditioning operations in 10 or less degreescentigrade outdoor air, mount inlet and outlet ducts on unit for assuring stable operations.
Countermeasure to snow and wind
Prevention the Outdoor unit from wind and snow damages in cold or snowy areas, snow hood shownbelow is recommended and helpful.
Note:1. Height of frame base for snow damage prevention (H) shall be twice as high as expected snowfall.
Width of frame base shall not exceed that of the unit. The frame base shall be made of angle steel,etc., and designed so that snow and wind slip through the structure. (If frame base is too wide, snowwill be accumulated on it.)
2. Install unit so that wind will not directly lash against openings of inlet and outletducts.
3. Build frame base at customer referring to this figure.Material :Galvanized steel plate 1.2TPainting :Overall painting with polyester powderColor :Munsell 5Y8/1 (same as that of unit)
4. To install units side by side,install a filler plate between the fan guard and theoutlet-side snow food as shown in Figure A.(The filler plate provided accommodates the installation pitch of between 30-80mm.)
5. When the unit is used in a cold region and the heating operation is continuously performed for a longtime when the outside air temperature is below freezing, install a heater to the unit base or take otherappropriate measures to prevent water from freezing on the base.

Countermeasure to windReferring to the figure shown below, take appropriate measures which will suit the actual situation of theplace for installation.A unit installed alone is vulnerable to strong winds. Select the installation site carefully to minimize theeffect of winds.To install a unit in a place where the wind always blows from the same direction, install the unit so thatthe outlet faces away from the direction of the wind.
Wind
Install the outdoor unit where seasonal winds do not blow directly against the unit, such as behind a building.
Install the outdoor unit to avoid having seasonal winds against the front of air outlet/inlet on the unit.

(1) Requirement on installation site1. In the way that the supply air is evenly distributed throughout the room,
2. In a place where the intruding air does not affect the unit's performance,
3. In a place where the flow of supply or return air is not obstructed,
4. In a place where airborne flammable oil droplets or steam are not present,
5. In a place where the risk of flammable gas leakage, migration, and/or accumulation is absent,
6. In a place where no high-frequency emitting devices are used,
7. In the way that the sensor of a fire alarm is not located on the supply air outlet side.
(Heated supply air may trigger a false alarm during heating operation.)
8. Do not install the unit in a place where acid solutions are frequently used.
9. Do not install the unit in a place where special chemical sprays (e.g., sulfuric gas) are used.
10. Do not install the unit in a place where corrosive gas or organic solvents are present.
11. In an environment high in oil mist, formic acid that is generated from a mixture of oil and drain water
can corrode the copper pipe and seriously shorten its life.
12. Corrosive gasses (e.g., sulfuric gas) that are generated in a place where food items are processed
and/or stored can damage the indoor unit and seriously shorten its life.
<Caution>
• If the units are operated for a long time at the dew point temperature of 23˚C[73˚F] or more, condensate
may collect and drip from the indoor units. If the units are operated under such conditions, cover the
entire surface of all indoor units with insulating materials with a thickness of between 10 mm[7/16 in.]
and 20 mm[13/16 in.] to prevent condensate from collecting.
• Indoor units that are installed in a machine room and connected to an adjacent room with a duct may
collect condensate if the temperature and humidity in the machine room rise high enough. If this
situation happens, circulate the air in the machine room and in the adjacent room to lower the
temperature and humidity in the machine room.
• If the unit is installed in a room with good airtightness, negative pressure may be created in the room,
which can hold the door shut. Create an air passage to prevent negative pressure from developing in the
room.

Note 1 The fixed disc of the pulley must be placed on the motor side.(Do not place the sliding piece on the motor side.) See Figure 1.
Note 2 After adjusting the width of the variable-width pulley, also adjust the alignment (centering). (Using a ruler, align the pulleys so that the width of 1 and 2 in Figure 2 is the same.)
Note 3 The pulley groove width in Table 1 are reference values. Adjust the PC ø of the variable-widthpulley by applying the specified number of turns.
73
• Adjusting the variable-width pulleyAdjust the PC ø of variable-width pulley according to the procedures described below.1Loosen the setscrew holding the fixed and the sliding discs in place.2Turn the sliding disc counter-clockwise until no gap is left (0 mm) between the fixed and the sliding
discs. 3Select the PC ø in Table 1 that is closest to the one to be used. Once the PC ø has been selected,
see the number of turns to apply that corresponds to the selected PC ø to determine how many turnsto apply to the sliding disc.
4Fix the fixed and the sliding discs in place with the setscrew. (Tightening torque:13.5 N·m)Let the tip of the setscrew rest in the V-shaped notch on the flat part of the fixed disc to hold thesliding disc in position.Apply Screw Lock (field supplied) to the setscrew to keep it from coming unscrewed. (Screwlock:ThreeBond 1322N or its equivalent)
5Perform a test run, and check that the pulley is not loose. When the test run is completed, check thesetscrew for looseness.
Note: Check that the desired rotation speed is in the operating range as indicated in the fan performancediagram. (If the rotation speed exceeds the operating range, the overcurrent relay on the fan will trip.)

(1) The fan pulley and the motor pulley must be aligned to meet the criteria shown in Figure 1 and Table 1.
(2) Set the tension for the V-belt so that the deflection force falls within the range as shown in the table in
!!-7.
(3) After the belt has been broken in on the pulley (after 24 to 28 hours of operation), check the belt for
looseness and adjust the belt tension as specified in step (2) above as necessary. When setting the
tension for a new belt, set it to a value 1.15 times the deflection force W.
(4) After the initial adjustment of the belt as described in step (3) above, readjust the belt tension every
2000 hours of operation. [The belt is due for replacement when the belt has been stretched by 2% of its
original length, including the initial stretch of 1%. (Approx. 5000 hours of operation)]
Note: Apply Screwlock (not supplied) to the retention screw on the pulley to prevent the screw from
loosening. Tighten the screw to the torque of 13.5 N·m. (Screwlock: Equivalent to ThreeBond 1322N)

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
Outdoor 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 Outdoor unit connected with system controller, power-supply to TB7 of the outdoor unit(s) is needed. The connector change from CN41 to CN40 at one of the outdoor units will enable the outdoor unit to supply power to TB7, or an extra power supplying unit PAC-SC50KUA should be used. The transmission cable (above 1.25mm2,shielded, CVVS/CPEVS/MVVS) among Outdoor units and system controllers is called central control transmission cable. The shield wire of the central control transmission cable must be grounded at the Outdoor unit whose CN41 is changed to CN40.
5 MA R/C transmission cable (0.3-1.25mm2) must be less than 200m in length, while ME R/C transmission cable (0.3-1.25mm2) must be less than 10m in length. But transmission cable to the ME R/C can be extend using a M-NET cable (>=1.25mm2) when the length is counted in the M-Net length. Both Compact MA and ME R/C transmission cables size 0.75~1.25mm2 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".

Thickness of wire for main power supply, capacities of the switch and system impedance
1. Use dedicated power supplies for the outdoor 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 outdoor 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 contact separation in each pole shall be provided by the Air Conditioner installer.
Warning:Be sure to use specified wires for connections and ensure no external force is imparted to terminal connections. If connections are not fixed firmly, heatingor fire may result.Be sure to use the appropriate type of overcurrent protection switch. Note that generated overcurrent may include some amount of direct current.
Caution: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 ofelectric 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.

6. Caution for refrigerant leakage
6-1. Refrigerant property
6-2. Confirm the Critical concentration and take countermeasure
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.
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 leakagehappens.
Critical concentrationCritical concentration hereby is the refrigerant concentration in which no human body would be hurt if immediate measures can be takenwhen refrigerant leakage happens.
Critical concentration of R410A: 0.30kg/m3
(The weight of refrigeration gas per 1 m3 air conditioning space.);The Critical concentration is subject to ISO5149, EN378-1.
For the PFAV system, the concentration of refrigerant leaked should not have a chance to exceed the Critical concentration in any situntion.
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. 6-1. The refrigerant of Outdoor unit here includes its originalcharge and additional charge at the site.The additional charge is calculated according to 3-3. "Refrigerant charging calculation", and shall not be over chargedat the site. Procedure 6-2-1~3 tells how to confirm maximum refrigerant leakage concentration (Rmax) and how to take countermeasures

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.
Maximum refrigerant leakage concentration (Rmax) Rmax=Wmax / V (kg/m3)
Maximum refrigerant leakage concentration (Rmax) Rmax=Wmax / V (kg/m3)where, Wmax=W1+W2
W1: Refrigerant weight of Outdoor unit No.1W2: Refrigerant weight of Outdoor unit No.2
Fig. 6-1 The maximum refrigerant leakage concentration6-2-1.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 areconsidered as one. The total space shall be added up.
6-2-2.Find the possible maximum leakage (Wmax) in the room. If a room has Indoor unit(s) from more than 1 Outdoor unit, add up the refriger-ant of the Outdoor units.
6-2-3.Divide (Wmax) by (V) to get the maximum refrigerant leakage concentration (Rmax).6-2-4.Find if there is any room in which the maximum refrigerant leakage concentration (Rmax) is over 0.30kg/m3.
If no, then the PFAV 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 Outdoor unit to one room.e.g. Using smaller model size but more Outdoor 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. 6-2~4.
