1 FEATURES

1. OPTIMAL PERFORMANCE AND EFFICIENT MAINTENANCE

(1) PEACEFUL SILENCE THROUGH WHISPER-QUIET OPERATION

This top quality floor-standing model guarantees near-silent operation through a newly developed low-noise fan. Air-duct

design has also been optimized through the adoption of microslit fans. Perfect for shops and office meeting-rooms.

(2) LONG LIFE FILTER

The long life filter allows 2,500 hours of maintenance-free operation in office environments not so dusty.

(3) SMOOTH REMOVAL

An open grill system permits filters to be removed smoothly and easily.

(4) EASY CLEANING

Dirt can be cleaned off simply because vanes are flockless.

2.INSTALLATION TIME GREATLY REDUCED

(1) EFFECTIVE PIPE CONNECTION

Raising the pipe connection position facilitates pipe arrangement, thus shortening installation time.

(2) CONVENIENT WIRING

A raised wire connection position means that wiring work can be conveniently implemented.

(3) WEIGHT REDUCTION

The use of plastics as assembly materials has realized a reduction in weight of 21kg. (PSH-5 74kg ➔ 53kg)

(4) PIPE DIRECTIONS

Pipes can be installed in four directions (rear, left, right, and bottom sides.)

6 WIRING DIAGRAM

NOTES :

1. Since the indoor transformer (T) is connected with 220V power, if 230,240V power is used. Change the wiring connection showing fig : w1.
fig : w1

When power supply is

2. Since the outdoor side electric wiring may change be sure to check the outdoor unit electric wiring during servicing.

3. Indoor and outdoor connecting wires are made with polarities, make wiring matching terminal.

4. Symbols used in circuit diagram above are. :connector :Terminal block

5. Emergency operation
If remote controller of microcomputer fails but there is no other trouble, emergency operation is possible by setting dip switch (SW3<I.B>) on the indoor
controller board.

[Check items]

(1) Compressor and fan.
(2) Check the trouble position using self diagnostic function. If the result of self diagnosis indicates protective device such as freeze protection is functioning,

emergency operation is not possible unless the cause is removed.
Emergency operation will be continuous operation mode due to power ON/OFF (ON/OFF with remote controller is not possible).

[Emergency operation procedure]

(1) Set the dip switch (SW3<I.B>) on the indoor controller board to 1 • 2 on and 3 off for cooling, and 1 • 2 • 3 on for heating.

(2) Turn on outdoor unit side circuit breaker, and then indoor unit side circuit breaker in this order.
(3) During emergency operation, the indoor fan runs on high speed but swing louver remains stop.
(4) Thermostat will not function. Cold air blows out for defrosting during heating, thus do not operate defrosting for a long time.
(5) Emergency cooling should be limited to 10 hours maximum (the indoor unit heat exchanger may freeze.)

Note 1. How to connect refrigerant pipes.

Factory supplied optional refrigerant pipings contain refrigerant at the above atmospheric pressures.
As long as connection takes no more than 5 minutes, no air will enter, and there will be no need for
air purging.
Remove the blind caps and make the connections within 5 minutes. After the connections for the
indoor and outdoor units are made, open the stop valve on the outdoor unit to allow refrigerant gas
to flow.
If piping length exceeds 5m, an additional charge of refrigerant is needed.
