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.

(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 control

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. 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.

Operation

OFF

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.

When the pipes or cables are routed at the bottom of the unit,

make sure that the through hole at the base of the unit does not get blocked

with the installation base.

Refer to the Installation Manual when installing units on an installation base.

In case of collective installation

When multiple units are installed adjacent to each other, secure enough space to allow

for air circulation and walkway between groups of units as shown in the figures below.

At least two sides must be left open.

As with the single installation, add the height that exceeds the height limit<h>

to the figures that are marked with an asterisk.

Take into consideration the surface strength,water drainage route,

piping route,and wiring route when preparing the installation site.

Build the foundation in such way that the corner of the installation leg is

securely supported as shown in the right figure.(Fig.A,B)

The protrusion length of the anchor bolt must not exceed 30mm.(Fig.A,B)

Use four fixing plates as shown in the right figure <field supply required>

when using post-installed anchor bolts.(Fig.C,D)

To prevent small animals and water from entering the unit and damaging its parts,

close the gap around the edges of through holes for pipes and wires with

filler plates <field supply required>.

(4) Weather countermeasure

In cold and/or snowy areas, sufficient countermeasures to wind and snow damages should be taken for operating unit in normal and good condition in winter time. Even in the other areas, full consideration is required for installation of unit in order to prevent abnormal operations caused by wind or snow. When

rain and snow directly fall on unit in the case of air-conditioning operations in 10 or less degrees centigrade 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 shown below 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, snow will be accumulated on it.)

2. Install unit so that wind will not directly lash against openings of inlet and outlet

ducts.

3. Build frame base at customer referring to this figure.

Material :Galvanized steel plate 1.2T Painting :Overall painting with polyester powder Color :Munsell 5Y8/1 (same as that of unit)

4. To install units side by side,install a filler plate between the fan guard and the

outlet-side snow food as shown in Figure A. (The filler plate provided accommodates the installation pitch of between 30-80 mm.)

5. When the unit is used in a cold region and the heating operation is continuously performed for a long

time when the outside air temperature is below freezing, install a heater to the unit base or take other appropriate measures to prevent water from freezing on the base.

Countermeasure to wind Referring to the figure shown below, take appropriate measures which will suit the actual situation of the place for installation. A unit installed alone is vulnerable to strong winds. Select the installation site carefully to minimize the effect of winds. To install a unit in a place where the wind always blows from the same direction, install the unit so that the 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 site

1. 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.

• 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.

This is the separation process. Use caution not to damage or scratch the unit during transportation. Take extra precautions when transporting the heat exchanger to prevent damaging its fin or heat transfer tube from shock.

2. Reassemble in the reverse order as above.

Replace all fixing screws and bolts back in, and tighten each of them to the proper tightening torque. Also, replace the thermistors back on with their wirings properly reconnected and fixed.

3. Do not compress the unit during separation or transportation.

After unit transportation or reassembling, check that the fan parts (pulley/fan/bearing) have no loosen screws and pulleys are in proper position so that the V-belt will not be damaged.

4. Sound and water leakage check

Check for abnormal sounds and water leakage after test run.

1. R410A Piping material

Refrigerant pipe for PFAV 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. The refrigerant piping should ensure the safety under the maximum operation pressure. MITSUBISHI ELECTRIC recommends pipe size as Table 1-1, or You shall follow the local industrial standard. Pipes of radical thickness 0.7mm or less shall not be used.

Flare

Due to the relative higher operation pressure of R410A compared to R22, the flare connection should follow dimensions mentioned below so as to achieve enough the air-tightness.

* For pipe sized ø19.05 (3/4") for R410A air conditioner, choice of pipe type is up to you.

1-2-3. PUHY-P-YHM's refrigerant charging calculation

Sample connection (with PFAV-P600VM-E-F)

Amount of refrigerant to be charged

Refrigerant for extended pipes (field piping) is not factory-charged to the outdoor unit. Add an appropriate amount of refrigerant for each pipe on site.

Record the size of each liquid pipe and the amount of refrigerant that was charged on the outdoor unit for future reference.

Calculating the amount of refrigerant to be charged

The amount of refrigerant to be charged is calculated with the size of the on-site-installed liquid pipes and their length. Calculate the amount of refrigerant to be charged according to the formula below. Round up the calculation result to the nearest 0.1kg. (i.e., 16.08 kg = 16.1 kg)

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, 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 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 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.

The need for switch settings depends on the system configuration. Be sure to read the section "4. An

Example of a System to which an MA Remote Controller is connected" before starting wiring work.

Set the switches with the power to the unit turned off.

Changes that are made to the settings while the unit is being energized will not take effect, and the unit

will not function properly.

3. M-NET control

Control wiring depends on system configurations.

Be sure to read the section "4. An Example of a System to which an MA Remote Controller is connected"

before starting wiring work.

(1) Types and maximum allowable length of cables

Control lines are categorized into two types: transmission line and remote controller line. Use the

appropriate type of cables and observe the maximum allowable length specified for a given system.

If a noise source is located near the unit, place the unit as far away from the noise source as possible to

reduce noise interference.

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 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 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 original charge and additional charge at the site. The additional charge is calculated according to 3-3. "Refrigerant charging calculation", and shall not be over charged

at the site

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.

6-2-1.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.

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.
