✻'-H' in the indoor units indicates that the unit pipes come out of the top of the unit (50/60Hz, fit to order).
✻PFD-type indoor units cannot be connected to outdoor units other than the ones specified above.
✻PFD-type indoor units and other types of indoor units cannot coexist in the same refrigerant system.
When using a PFD-P500VM-A as an indoor unit, connect 2 PUD-P250YMF-C outdoor units to each
indoor unit and operate with a built-in remote control for the indoor unit.
✻1: Bold line indicates refrigerant piping (gas/liquid). This system consists of 2 refrigerant circuits.
✻2: Indicates TB3-type transmission line that connects the indoor and outdoor units.
This system consists of 2 refrigerant circuits.
✻3: Indicates TB7-type transmission line that allows the unit to communicate with the controller.
When using a PFD-P250VM-A as an indoor unit, connect an outdoor unit PUD-P250YMF-C to each
indoor unit and operate with a built-in remote control for the indoor unit.

2-4. Correction by refrigerant piping length
To obtain a decrease in cooling/heating capacity due to refrigerant piping extension, multiply by the capacity
correction factor based on the refrigerant piping equivalent length in the table below.
Equivalent length = (Actual piping length to the farthest indoor unit) + (0.50 ✕number of bent on the piping)m

■ Selecting Refrigerant Pipes
■ Adding the Refrigerant
Gas pipe: ø28.58 ✕ 2
Liquid pipe: ø12.7 ✕ 2
A
Net length: under 120m, Total Length: under 150m
Under 50m
(Under 40m if the outdoor unit is installed below the indoor unit.
Under 15m if the outdoor temperature is under 10˚C.)
The outdoor unit is shipped with 8.5 kg of
refrigerant. It does not include enough
refrigerant for extra piping system.
Use additional refrigerant for each
refrigerant piping system (2 refrigerant
circuits).
Record the length of the pipe and the
amount of the added refrigerant on the
outdoor unit for services in the future.
■ Calculating the amount of refrigerant to
be added
·The amount of refrigerant needed for
additional piping depends on the diameter
and the length of the added liquid pipes.
·Calculate the amount to be added as
shown on the right, and add the refrigerant
in that amount.
·Round up the figure under 0.1kg.
(e.g. 11.06kg would be 11.1kg).
<The amount of refrigerant to be added>
Size of the liquid pipe
Total length of the pipe with a diameter of ø12.7 ✕0.12
(m) ✕0.12 (kg/m)
+ 2.0kg
(i.e.) When using a 120m pipe with a diameter of ø12.7
120m ✕0.12kg/m + 2.0kg = 16.4 kg
Caution
Charge Liquid Refrigerant
Filling the equipment with gas refrigerant will result in a power loss due to transformation of refrigerant in the tank.

(1) Specifications of control wiring and maximum length of wiring
Transmission line is a type of control line. When the source of noise is located adjacent to the unit, the use
of shield cable as well as moving the unit as far away from the noise source are recommended.

8-3.Types of switch settings and setting methods
Whether a particular system requires switch settings depends on its components. Refer to the section “7-4
Wiring and Address Setting”before conducting electrical work.
Keep the power turned off while setting the switches. If settings are changed while being powered, the
changed settings will not register, and the unit may malfunction.

(1) Address setting
19
This system requires address setting. The range of address varies depending on the type of unit. Refer to
“7-4 Wiring and Address Setting”for details.
(3) Choosing the temperature detection spot by indoor unit (Factory Setting: SWC “Standard”)
When using the suction temperature sensor, set SWC to “Option.”
(4) Setting the MA “Sub”controller
When using two remote controllers or running two indoor units as a group, one of the controllers must be
set to “Sub”controller.
✻No more than two remote controllers can be connected to a group.
(Factory setting: “Main”)
Set the controller according to the following procedure. Refer also to the instructions manual supplied with
the MA remote controller.

✻1: 10HP only has the main controller.
✻2: Avoid using the same address as the ones used by the indoor/outdoor units in another refrigerant system; choose a different
one in the range specified above.
✻3: When setting the address to 100, set the switch to 50.
Assign a number to all indoor units, starting with 1 and using
sequential numbers. Use odd numbers for the top controller and
even numbers for the bottom controller of the indoor units. Use
odd numbers starting with 01 for 10HP system.
Add 50 to the address assigned to the indoor unit to which the
outdoor or heat-source unit is connected.
(2) Setting the outdoor unit power-source switch connector (Factory setting: CN41 Connected)
Power supply switch unit
<When power-supply unit is not connected to the centralized control transmission line>
Replace the power source switch connector CN41 with CN40 on only one of the outdoor units
<When connecting the power-supply unit>
Use CN41 as it is.
