Fresh Air Intake Indoor Unit Type
1. Outline of fresh air intake unit
• Type: Concealed Duct High Static Pressure type
Three models (5HP, 8HP, 10HP) are prepared.
• Connectable outdoor unit
Three series (MMY-MAPXXXXT8, MAPXXXXHT8, MAPXXXXHT7) of Cooling/Heating selecting
Super module multi type outdoor unit.
• Corresponding system
Corresponds to a system in which there are the fresh air intake units and the indoor air
conditioners.
(For the fresh air intake units, up to 2 units for one system and also within 30% to capacity of the
connectable indoor air conditioners are allowed.)
• Definition
The fresh air intake unit means an air controller for taken-in fresh air.
Intake of the fresh air often influences on the system so that the normal control of the air conditioner
becomes difficult or gives a large load upon air controller and cooling performance.
Therefore it is frequently adopted to handle the fresh air to a certain condition before the fresh air
will enter in the main air conditioner.
This handling device is called a fresh air intake unit.
NOTE:
The Fresh Air Intake unit is an air conditioner provided to handle the fresh air load and is not to control
the room temperature. For correspondence to the load of the indoor air controller, set an air
conditioner separately.

2. System able to be combined
The fresh air intake unit is connectable to S-MMS (Super Modular Multi system).
However this is not connectable to S-HRM (Super Heat Recovery Multi system).
0.5m or less
80 to 100% to capacity of the outdoor
Keep the height difference between the fresh air intake units to 0.5m or less.
Up to two fresh air intake
units occupy 30% or less
· The fresh air intake unit is usually used together with the indoor units on one line of the multi system.
The fresh air intake unit only cannot be connected.
· The total capacity of the indoor units and the fresh air intake units is restricted to 80% to 100%
against the capacity of the outdoor units. (This restriction should be strictly kept for correct control
of the refrigerant.)
· Up to two fresh air intake units can be connected on one line of the multi system.
The allowable total capacity of the two fresh air intake units shall be 30% or less against the total
capacity of the indoor units (including the fresh air intake units).
Connection which stretches
over two floors is unavailable
Height difference:
0.5m or more

3. Use Conditions
· In COOL mode, if temperature of the fresh air is under the setup temp. +3°C, FAN status is
automatically made. When temperature of the fresh air is under 19°C, FAN status is also made
regardless of the setup temperature.
· In HEAT mode, if temperature of the fresh air is over the setup temp. -3°C, FAN status is
automatically made. When temperature of the fresh air is over 15°C, FAN status is also made
regardless of the setup temperature.
• Operable mode and discharge temp setup range

• Special mentions
1. The fan operation of the Fresh Air Intake unit stops during defrosting.
However the fan operation is enabled to continue by selection.
2. When a central controller is used, divide zone setup of indoor air conditioner and fresh air intake
unit.
3. The standard is to control the discharge temperature. However the priority is given to the capacity
control for the indoor air conditioner in a system in which the normal indoor air conditioner
concurrently operated.
4. The fresh air intake unit cannot be connected with remote controller group of the indoor air
conditioner.
5. In heating operation, if the temperature is below –5°C, the operation stops automatically. (FAN stop)
(To protect the refrigerant cycle)
6. In cooling operation, if the temperature is below 5°C, the operation stops automatically. (FAN stop)

<Installation Notice>
1 The check port should be 600 x 600mm.
2 A slope the piping outside of the unit downward at 1/100.
Be sure to do heat insulating to the connecting peat with the indoor unit. In complete heat insulating may cause
dewing.
3 Check the water drainage is surely performed at the trial operation.
4 Do not install the air conditioner in a salty place such as seaside area and a place where sulfurous gasgenerated
such as in a spa.
5 Please clean the drain plate before the season of cooling air conditioning.
Water overflows from the drain plate when the drain plate and the drain poart are dirty, and the ceiling might be wet.
6 The air filter is not built into the Fresh Air intake indoor unit.
Please remove the dust that enters from air by installing optional Filter chamber, Pre-filter, and High Efficiency Filter.
If no air filter is installed, dust will collect in the heat exchanger, which may cause the air conditioner to fail or to leak.
(local prpcure)
7 Place where the unit cane installed horizontally.
8 Set the canvas duct at air inlet port and air supply port. It is to avoid conveyance of vibration, abnormal resonance
sound and also to make easy the disassembly of the main unit in service time.
9 Be sure to connect the wire and connection cable while matching the terminal.
Please refer to the wiring diagram for details.
10 Please note that the size is different because of MMD-AP0481HFE and MMD-AP0721HFE/MMD-AP0961HFE in the
electric part box.
11 The heat insulator is pasted to externals of the main body of the product. (Bottom board thickness : 16mm, other
thickness : 6mm)
12 Be sure to set the duct at air filter with descending inclination because the suction duct of the this unit is exposed to
outdoors and therefore rainwater, leaves and birds are easy to enter in if it is set horizontally.
Attching wire netting and others to end of the suction duct is also recommended.
13 Set the air inlet duct at descending inclination so that water can be drained even if rainwater enters in.
14 The balloon entrance connection flange and the inhalation mouth connection flange are installed in the main body
of the product.
Please use it detaching it when you connect the duct.
Please obtain Filter chamber directly in the main body of the product when you install Filter chamber and obtain
installation Air intake port connecting flange for C side of A.
15 Connect the ducts directly so that the ducts do not weight on the main unit.
Moreover, please do not damage, and do not knock down air supply temperature sensor when you connect the air
supply duct.
16 Be sure to apply heat insulation for the duct to prevent dewing.
Especially, when it is inhaled to heat it, the be dewy on the surface of the outside of the duct because cold air enters.
Please put the heat insulator.
17 When installing the drain pump and filter chamber sold separately, refer to attachment installation manual.
