1.SPACE-SAVING CENTRALLY LOCATED CEILING RECESSED INSTALLATION

2.4-WAY AIR FLOW SYSTEM

This series allows you to select from 2, 3, and 4 way air flow directions according to your requirement. As a result, you get superb flexibility in choosing a configuration that gives you maximum cooling efficiency in a neat and unobstructive installa- tion.

3. STABLE COOLING EVEN AT OUTDOOR TEMPERATURES AS LOW AS 0-F MAKES

YEARROUND AIR-CONDITIONING POSSIBLE. WIND BAFFLE REQUIRED.

The microprocessor automatically adjusts fan speed in accordance with outdoor temperature to maintain the coolant at an even condensing temperature. The result is smooth, efficient cooling even when temperatures outdoors drop as low as 0-F. This makes the unit ideal for a wide range of specialized cooling needs, such as rooms with many office machines or com- puters and areas subject to strong sunlight.

4.ADVANCED MICROPROCESSOR CONTROL

(1)Easy to use Microprocessor (remote controller)

1)Ultra-Thin Remote Controller

The streamlined, wide controller is designed to blend with any kind of interior and the adoption of a sophisticated micro- processor allows you to carry out a wide range of operations easily.

2)Attractive Liquid Crystal Display (LCD)

Units operation mode, set temperature, room temperature, timer setting, fan speed, and air flow direction are displayed on the remote controller with the easily understood visual Liquid Crystal Display (LCD).

3)Convenient 24-Hour ON-OFF Timer

The timer allows Mr.SLIM to be switched on or off automatically at the time is shown on the LCD.

4)Self-Diagnostic Feature Indicates Faults Instantly

In the rare case when a problem occurs, the unit stops operating and the set temperature indicator changes to the self- diagnostic indicator, indicating the location of the fault.

If the check switch is pressed twice, the unit stops operating and the check mode is initiated. The cause of the most recent problem stored in the memory is displayed on the LCD. This is extremely useful for maintenance purposes.

5)Useful Memory Feature for Storing Instructions

The previous set value is memorized so that constant temperature control can be obtained. This is convenient when, for example, a power failure occurs.

(2)Non-polar Two-Wire Remote Controller Cables

The non-polar, two-wire type remote controller cable is slim, installation is simple and trouble-free. Remote controller wire can be extended up to 550 yards.
