FEATURES

1. AIR OUTLET

New PCFY series models have 1 air outlet (auto vane switching of horizontal air flow / down flow by switched by auto vane)
instead of 2 (horizontal, and down frows).

2. EASY TO CLEAN ; FLOCKLESS VANE

With our original air current control mechanism, a flockless vane is
newly adapted.
The flockless vane prevents the condensation on the vane.
By changing the vane to the flockless type, the unit can be cleaned
much easier with mild household detergent.

3. NEW MATERIALS FOR BETTER OIL RESISTANCE

We have changed the materials of grill, filer, fan and fan casing from ABS to P.P. (polypropylene) for better oil resistance. As
a result, oil crazing is cut in half.

1 Removed the knockout work by separating the piping space

from the air outlet for efficiency of the piping work.

❈ Knockout work is needed for the top part. When optional

drain-up machine is installed, the refrigerant pipe exits out
from the top.

2 Improved the flexibility by making it possible for drainage

pipe to exit not only from the right side back but also from
the left side back.

❈ Please move the rubber plug for the unit to the right joint

when drainage pipe exits from the left side.

4. SIMPLIFIED INSTALLATION WORK (DIRECT SUSPENDING METHOD)

Simplified the installation work by changing the suspending method to the direct suspending method (suspending the unit
directly from the suspension fixture).
In this way, the unit can be attached to the suspension fixture without removing the installation parts off (Only the side cover
is removed). This method is much simpler than the ¨One-time installation method¨.

6.ADVANCED MICROPROCESSOR [PAR-F25MA]

(1)Easy to use microprocessor

1)Ultra-thin remote controller

The streamlinde,square controller is designed to blend well with
any interior.Also,the sophisticated microproceeor allows you to
easily carry out a wide range of operations.

2)Attractive liquid crystal display(LCD)

The unit´s operation mode,set temperature,room
temperature,timer setting,fan speed,louver oper-ation,and air flow
direction are displayed on the remote controller´s easy-to-read
Liquid Crystal Dis-play(LCD).

3)Convenient 24-hour ON-OFF timer

The timer switches Mr.SLIM on and off automati-cally at the time
you set. Once the timer is set,the remaining time is shown on the
LCD.

Linear expansion valve

① Operation summary of the linear expansion valve.

• Linear expansion valve open/close through stepping motor after receiving the pulse signal from the indoor controller board.

• Valve opening can be changed in proportion to the number of pulse signal.

Closing a valve : 1 → 2 → 3 → 4 → 1

The output pulse shift as above order.

❈ 1. When linear expasion valve operation stops, all output phase

become OFF.

2. At phase interruption or when phase does not shift in order,
motor does not rotate smoothly and motor will lock and vibrate.

❈ When the switch is turned on, 2200 pulse opening valve signal

will be send till it goes to

A point in order to define the valve

position.
When the valve move smoothly, there is no noise or vibration
occur from the linear expansion valve : however, when the pulse
number moves from

E to A or when the valve is locked, more

noise can be hear than normal situation.

❈ Noise can be detected by placing the ear against the screw

driver handle while putting the screw driver to the linear
expansion valve.

Symptom

Check points

Operation circuit
failure of the micro
processor

Disconnect the connector on the controller board, then
connect LED for checking.

Pulse signal will be sending out for 10 seconds as soon as
the main switch is rurned on. If there is LRD with lights on or
lights off, it means the operation circuit is abnormal.

Countermeasures

Exchange the indoor
controller board at drive
circuit failure.

Lock at the linear
expansion valve
mechanism area.

Valve doesn’t close
completely(thermisto
r leaking)

Wrong connection of
the connector or
contact failure.

To check the linear expansion valve of the indoor unit,
operate the indoor unit in fan mode and operate other indoor
units in cooling mode then check the pipe temperature <liquid

pipe temperature> of the indoor unit by
monitorring the outdoor multi controller
board operation. During fan operation,
linear expansion valve is closed completely
and if there are some leaking, detecting
temperature of the thermistor will go lower.
If the detected temperature is much lower

than the temperature indicated in the
remote contoroller, it means the valve is not closed all the
way. It is not necessary to exchange the linear expasion
valve, if the leakage is small or does not make any trouble.

Liquid pipe
thermistor

Linear
expansion
valve

Morter will idle and make ticking noise when motor is
operated while the linear expansion valve is locked. This
ticking noise is the sign of the abnormality.

Check the color of lead wire and missing terminal of the
connector.
Check the color of lead wire and missing terminal of the
connector.

Exchange the linear
expansion valve.

Exchange the linear
expasion valve.

If large amount of
thermistor is leaked,
exchande the linear
expasion valve.

Disconnect the connecttor
at the controller board,
then check the continuity.

Measure the resistance between the each coil(red-white, red­orange, brown-yellow, brown-blue) using atester. It is normal
if the resistance is in the range of 150 '±10%.

Short or breakage of
the motor coil of the
linear expansion
valve.
