1. AIR OUTLET

New PCH 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 flows).

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.

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”.

5. IMPROVING EFFICIENCY OF PIPING WORK

1Removed the knockout work by separating the piping space from the air outlet for efficiency of the piping work.

2Improved 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.

6. EASY MAINTENANCE ; NO MAINTENANCE NECESSARY FOR 2500 HOURS

The new long-life air filter can be used continuously 2500 hours without maintenance (at general office situation).

7. STABLE COOLING EVEN AT OUTDOOR TEMPERATURES AS LOW AS 23˚F MAKES YEAR-ROUND AIR-CONDITIONING POSSIBLE

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 23˚F. This makes the unit ideal for a wide range of specialised cooling needs, such as rooms with many office machines or computers and areas subject to strong sunlight.

Remote controller display

CENTRALLY CONTROLLED display

This indicates when the unit is controlled by optional features such as central control type remote controller.

TIMER display

This indicates when the continuous operation and time operation modes are set.

It also display the time for the timer operation at the same time as when it is set.

OPERATION MODE display

This indicates the operation mode.

STANDBY display

This indicates when the standby mode is set from the time the heat operation starts until the heating air is discharged.

DEFROST display

This indicates when the defrost operation is performed.

CHECK display

This indicates when a malfunction has occurred in the unit which should be checked.

CLOCK display

The current time , start time and stop time can be displayed in ten second intervals by pressing the time switch button. The start time or stop time is always displayed during the timer operation.

In this display example on the bottom left, a condition where all display lamps light is shown for explanation purposes although this differs from actual operation.

Notes 1. I.D.B. : Intake air dry-bulb					temperature
CA : Capacity (x103				Btu/h), PC : Power Consumption (kW)

2.When booster heater is "on", total capacity and total power consumption should be added the figures described in booster heater column.

•Booster heater ON : When the set temperature is higher than the room temperature by more than 5.4 deg. •Booster heater OFF : When the set temperature is higher than the room temperature by less than 3.6 deg.

3.Heating capacity correction factors.

	Model	Airflow	Air speed	Coverage
		(CFM)	(ft/sec)	range(ft)
	PCH24GK	880	13.5	40
	PCH30GK	1,240	14.8	50
	PCH36GK	1,240	14.8	50
	PCH42GK	1,240	14.8	50

The air coverage range is the value up to the position where the air speed is 0.8ft/sec. when air is blown out horizontally from the unit at the High notch position.

The coverage range should be used only as a general guideline since it varies according to the size of the room and furniture installed inside the room.
