Floor StandingSeries PSH

No.OC142

The Slim Line. From Mitsubishi Electric.

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.)

Disperses air up and down

Disperses air left and right.

Removes dust and pollutants from inhaled air.

(Inhales air from room.)

Attention

● Pressing the UP and DOWN buttons together for more than two seconds will initiate the “test run” or “self-diagnostic” mode. Avoid pressing these buttons simultaneously during normal operation. Press the ON/OFF button to cancel test run or selfdiagnostic mode.

●All green lamps turn off when air conditioner is OFF.

●Avoid operation of buttons with fingernails or other sharp objects. Sharp objects may scratch operating panel.

● Controller

Settings remain in effect' until changed. The air conditioner can be operated by simply pressing ON/OFF button once settings have been made.

This button is used to

change between display of room temperature and

display of remaining time

on the timer during “AUTO

STOP” operation. Green lamps light in selected display mode.

TIMER/TEMP. button

Pressing button starts operation. Pressing again stops operation. Green lamp remains lit during operation.

ON/OFF button

This button is used to change between cooling, DRYING and heating operation modes. One of three green lamps lights to indicate mode in effect.

MODE SELECT button

This button is used to change between low and high fan speeds. One of two green lamps lights to indicate which fan speed is in effect.

FAN SPEED button

Used to select timed starting or stopping. Green lamp lights to indicate timer mode selected.

TIMER MODE button

This button is used to switch swing louver ON/OFF.

LOUVER button

●Temperature control (While green “TEMP” lamp

is lighting.) Use UP and DOWN buttons to set desired temperature between 18 and 29 °C in COOL or DRY operation.

●Use UP and DOWN buttons to set desired

temperature between 18 and 29 °C in HEAT operation.

●Timed operation (While green “TIMER“ lamp is

lighting.) Use UP and DOWN buttons to set timed operation between one and twelve hours.

UP and DOWN buttons

Lamps indicate time remaining

until timer stops operation.

Green lamps display the

remaining number of hours.

Lamps display temperature

settings actual room temperatures.

●Temperature settings : Green lamps light.

●Temperature in room : Green lamps flash.
