Note)
∗
1: Cooling capacity is the value at standard point (inlet oil temperature and room temperature: 35˚C, ISO VG32 oil). The product tolerance is
approx. ±5%.
∗
2: Be sure to use a commercial power supply. Using an inverter power supply may result in burnout. Voltage fluctuation range should be
within ±10%.
If voltage fluctuation exceeds ±10%, consult DAIKIN.
∗
3: For the different-voltage model, three types (–E1, –E2 and –E3) are available depending on the power supply voltage.
∗
4: The optional machine temperature tuning thermistor is required. (For details, see page .)
∗
5: The “–C” model is supplied with MSDS (Material Safety Data Sheet) for refrigerant R410A.
∗
6: This product is not equipped with a circuit breaker. The user must prepare a circuit breaker.
∗
7: Conventional “1 HP”-equivalent models (AKS105AK/AKZ(S)257 class) have been integrated into AKZ328 (“1.2 HP”-equivalent).
