Elegant design and compact dimensions ideal for offices, stores and residential uses
ŶThe PKFY auto-vane feature delivers optimal air distribution
and uniform temperature throughout your space.
ŶAll of the performance and design flexibility come in a unit
that is remarkably easy to install and maintain.
ŶThe template and back mounting plate shipped with each
unit makes application a snap.
ŶOperation is among the quietest available
ŶFront grille opens for easy filter cleaning
ŶA wide selection for your design and performance needs
ŶThey are more compact and weigh less than most competitive
units. In addition, they are extremely quiet with one of the
lowest sound ratings available from any manufacturer.
Optimized airflow passage.
Avoid turbo air returning
Avoid dewing at outlet.

Note
1.At servicing for outdoor unit, always follow the wiring diagram of outdoor unit.
2.In case of using MA-remote controller,please connect MA-remote controller cable in an accessory
to the connector . (Remote controller wire is non-polar.)
3.In case of using M-NET,please connect to TB5 (Transmission line is non-polar.)
4.Symbols used in wiring diagram above are, : terminal block, : connector
5.The setting of the SW2 dip switches differs in the capacity. For the detail, refer to the fig :*1.
6.Please set the switch SW5 according to the power supply voltage.
Set SW5 to 230V side when the power supply is 230 volts.
When the power supply is 208 volts, set SW5 to 208V side.

Wiring details and installation details should be referred to Installation Manual of PKFY-P-NBMU-E. (RG79D501)
1. Connecting External Output Cable
Use the cable with the connector that fits the connector on the indoor unit control board.
• External output cable (PAC-725AD)
This cable is used to connect the relay circuit that is used for an inter locked operation of indoor unit and electric heater. Connect the cable to connector CN52
on the indoor unit control board.
2. Field-supplied Wiring
A basic connection method is shown. Please refer to the service manual for details.
• For relay X use the specifications given bellow Operation coil
Rated voltage: 12VDC
Power consumption: 0.9W or less
* Use the diode that is recommended by the relay manufacturer at both of the
relay coil.
• The length of the electrical wiring for the PAC-725AD is 2 meters (6-1/2 ft)
To extend this length, use sheathed 2-core cable.
Control cable type: CVV, CVS, CPEV or equivalent.
Cable size: 0.5 mm2to 1.25 mm2(16 to 22 AWG)
Don’t extend the cable more than 10 meters (32 ft)
