5.1 GENERAL INFORMATION

5.1.1 Specific features

(1) The long piping makes the location of the inside and units flexible.

¡ No need for additional charge of refrigerant : 30m

¡ Maximum piping length : 40m

(2) Connectable indoor capacity

Number of connectable units : 3 units

Total of indoor units (class kW) : 11.0kW

(3) Indoor units are available with 5 capacities.

5 capacities ................ 22, 25, 28, 35, 50, 60

Types ......................... Wall mounted type (SKM).

4-way ceiling cassette type (STM).

Ducted type (SRRM).

(4) Inverter (Frequency converter) for multi-steps power control

¡ Heating / Cooling

The rotational speed of a compressor is changed in step in relation to varying load, to interlock with the indoor and outdoor unit

fans controlled to changes in frequency, thus controlling the power.

¡ Allowing quick heating/cooling operation during start-up period. Constant room temperature by fine-tuned control after the

unit has stabilized.

(5) Fuzzy control

Fuzzy control calculates the amount of variation in the difference between the suction air temperature and the setting temperature

in compliance with the fuzzy rules in order to control the air capacity and the inverter frequency.

(6) Self diagnosis function

We are constantly trying to do better service to our customers by installing such judges that show abnormality of operation as

follows. (See Page 74)

¡ The combinations of the indoor units is indicated by numbers. They are read as follows.

(Example) SKM22ZD-S / 22 SKM35ZD-S / 35

¡ The capacity of the indoor units is shown by rooms. If this exceeds the maximum capacity of the outdoor unit, the demand

capacity will be proportionally distributed.

¡ If units are to be combined, use the table below to make the proper selection.

(2) Correction of cooling and heating capacity in relation to one way length of refrigerant piping

It is necessary to correct the cooling and heating capacity in relation to the one way piping length between the indoor and outdoor

units.

(3) Correction relative to frosting on outdoor heat exchanger during heating

In additions to the foregoing corrections (1), (2) the heating capacity needs to be adjusted also with respect to the frosting on the

outdoor heat exchanger.

(3) Drain motor forced operation functions (STM, SRRM only)

(a) Operation

• When the float switch detects drain water, please use the wireless remote control to set the operation mode to "heating",

set the temperature to 30°C, and set the timer to continuous operation.

• When the float switch detects drain water, press the TEST switch on wired remote control for 3 seconds.

(b) Detail of operation

Sets the decision speed to 0 rps, stops the indoor fan motor, and only lets the drain motor run for 5 minutes. After this

operation finishes, if the float switch detects drain water, it will display an error and stop operation.

(C) Reset condition

(i) When the drain motor has run for 5 minutes.

(ii) Use the remote control to set the operation mode to heating, set the temperature to 30°C, and set the timer to something

(ii) High-power operations

Notes (1) Power blackout auto restart function is set at on when the air-conditioner is shipped from the factory. Consult with your dealer if this function needs to

be switched off.

(2) When power failure ocurrs, the timer setting is cancelled. Once power is resumed, reset the timer.

(3) If the jumper wire (J7) “REMOTE/AUTORESTART (SKM), AUTORESTART (STM, SRRM) ” is cut, auto restart is disabled. (See the diagram at

above)
