1. COMPACT DESIGN

The PK series models have been downsized and now require such minimal wall space that they can even be installed above windows. For the PKH18/24FK, 13in of wall space between the ceiling and the window allows “above window” installation (14.5in for the PKH30/36FK)

2. A FURTHER REFINEMENT OF COMFORT WITH NOISE SUPPRESSION

Remarkably low-noise operation has been achieved through the development of a “near-silent” fan and a design which minimizes airflow resistance.

3. AUTO FLAP SHUTTER

With a simple flick of the OFF switch the air outlet can be closed off with a shutter. The shutter also functions as a flap during operation to adjust the air flow angle, with “AutoAngle 1” securing a comfortable air flow.

4.INSTALLATION : FAST AND ENDLESSLY ADAPTABLE

(1)External piping

An external piping connection of 24in and a very light body promote trouble-free installation for PKH18FK.

(2)Multi-directional piping

Multi directional drain and refrigerant piping rodically improves flexibility in selecting installation layouts. PKH18FK drain piping can be installed in 5 directions, while PKH30/36FK models boast refrigerant piping in 4 directions and drain piping in 2 directions.

(3)Back plate installation guide

The back plate installation guide gives clear instructions on installation positions. The enlarged back plate secures the unit firmly to the wall, while the support piece which lifts the unit makes left side piping work much easier.

(4)Front power supply box

The front power supply box allows electrical wiring work to be performed easily even after the indoor unit has been fully installed. All the screws for the indoor unit can be tightened from the front side thus ensuring smooth installation.

(only for PKH18/24FK)

(5)Easily removable filter

The presence of thumbscrews on the filters means that the filters can be quickly and smoothly removed. (only for PKH30/36FK)

5.ADVANCED MICROPROCESSOR

(1)Easy to Use Microprocessor

1)Ultra-Thin Remote Controller

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

2)Ultra-Thin Remote Controller

Units operation mode, set temperature, room temperature, timer setting, fan speed, louver operation, 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 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 troublefree. Remote controller wire can be extended up to 550 yards.

(3)Automatic Cooling / Heating Changeover Operation

An automatic cooling and heating changeover operation system is provided to ensure easy control and year-round air conditioning.

Once the desired temperature is set, unit operation is switched automatically between cooling and heating, in accordance with the room temperatures as low as 23oF.

6.REDI-CHARGED REFRIGERANT SYSTEM

PRE-CHARGE REFRIGERANT REQUIRED FOR MAXIMUM PIPING LENGTH AT

SHIPMENT. PREVENTING TROUBLES DUE TO SHORTAGE OF REFRIGERANT.

The unique refrigerant circuit and a large accumulator always controls the refrigerant to its optimum condition regardless of the length of 164ft maximum or 25ft minimum. The additional refrigerant charging work at the field which often caused uncertain problems heretofore is completely eliminated. This unique system serves to improve the quality of work and reliability, and also helps to speed up the installation work.

With normal circulation systems, a high-pressure refrigerant, condensed for cooling by the outdoor heat exacanger, is reduced in pressure by capillary tubes in the indoor unit after passing through the restrictor valve in the outdoor unit (see Figure 1). With the new circulation system, the direction of the restrictor valve is reversed as shown in Figure 2, and the condensed high pressure refrigerant is reduced in pressure by the capacity tubes in the outdoor unit. This results in a “twophase refrigerant” of reduced pressure in the liquid section of the piping, The density of this two-phase refrigerant is 1/3~ 1/2 of that of the high pressure liquid refrigerant, and thus is required in smaller amounts (see Figures 1 and 2). As a result, the length of the piping can be extended further, and the effects of height differences are reduced. These new circulation system are also equipped with a large accumulator which allows the refrigerant required for the 100ft piping length to be enclosed in the outdoor unit. The result is an air conditioner that requires no charging unless piping is extended beyond 100ft.

7. HIGH RELIABILITY AND EASY SERVICING

In addition to the self-diagnostic function, units are also equipped with a 3-minute time delay mechanism (cooling), an auto restart function, an emergency operation function, a test run switch, etc., to assure high reliability and easy servicing.

8. FOUR-WAY PIPING ACCESS MAKES INSTALLATION LAYOUT EASY

Piping on the outdoor unit may be connected from either of four directions: front, rear, side or beneath the base.

This easy-access design makes it possible to install a number of units in a compact arrangement at a single site. The outdoor unit allows for unheard-of flexibility in detemining a piping layout, thus greatly simplifying installation.

9. FRONT-ACCESS FACILITATES MAINTENANCE

The outdoor unit has been designed with a frontaccess service panel that allows easy access to all maintenance point, regardless of the installation layout. What’s more, this front panel may be removed by loosening only two screws. It all adds up to greatly simplified maintenance work.

10. NITROGEN GAS IS CHARGED TO INDOOR UNIT

Indoor unit and refrigerant pipes are charged with nitrogen gas (N2) instead of R-22 before shipment from the factory.

NOTES :

1.

Since the indoor fan motor (MF) is connected with 230V power, using 208V power will require a setting change of the dip switch (SW7<I.B>) on the indoor con-

troller board as shown in fig : w 1.

3.Since the outdoor side electric wiring may change be sure to check the outdoor unit electric wiring for servicing.

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

5.Symbols used in wiring diagram above are, ¤¤ : Connector, /: Terminal block.

6.Emergency operation

If remote controller or 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)Make sure that no other trouble exist the outdoor unit. Trouble with the outdoor unit prevents emergency operation.

(If any trouble exists the outdoor unit error code "P8" will be displayed on the remote controller and the trouble position will be shown on the outdoor controller board LED. See electric wiring diagram of the outdoor unit for details.)

(2)Make sure that there is no trouble with the indoor fan.

Emergency operation will be continuous operation mode due to power ON/OFF (ON/OFF with the remote controller is not possible). [Emergency operation procedure]

(1)Set the dip switch (SW3<I.B>) on the indoor controller board to 1 on and 2 off for cooling and 1 - 2 on for heating. (2)Turn on outdoor unit side circuit breaker, then indoor unit side circuit breaker.

(3)During emergency operation indoor fan runs at high speed but automatic vane remains stopped. If the air outlet is blocked up with the vane, Open it with your hands.

(4)Thermostat will not function. Cold air blows out for defrosting during heating thus do not operate defrosting for along time. (5)Emergency cooling should be limited to 10 hours maximum.

(The indoor unit heat exchanger may freeze).

(6)After every operation, switch the fan connector to FAN1, and set all dip switches (SW3<I.B>) to OFF.

How to use SW1 and 2

●Pressing SW1 erases the past check contents loaded on the microcomputer.

●The output display (light) remains during opera-

tion but pressing SW2 displays the past check contents in flashing mode. Pressing the switch again retums to output display (light).

NOTES : 1. If the operation stops to function of the protection device, the check display flashes.

2. Symbols used in wiring diagram above are. /:Terminal block, ¤¤¤ :Connector, ¤ :PC board insertion tab.

CAUTION FOR SERVICING		White connector
	s
● The connector marked—		¤— is to turn the compressor ON-OFF during servicing.

The compressor stops by disconnecting the white connector as shown at the right.

CAUTIONS FOR POWER SUPPLY WIRING

● Since LD8 lights when normal power is turned "ON", check the power supply with the "ON" or "OFF" LD8.

wSince the indoor transformer (T) is connected with 230V power, if 208V power is used, change the wiring connection as shown in the right figure.
