Heating: Indoor: DB20℃/ WB15℃ Outdoor: DB7℃/ WB 6℃

2．The Sound Pressure Level is based on the following conditions:

Outdoor unit：

Measure the noise value of 3 points，the points are1 meter in front of the three sides (front/left/right) of the unit surface and height =1/2(unit

height +1) meter from floor level, and calculate the weighted average of the noise.

Indoor unit：

Ducted: Measure the noise value of the point 1.4m below the unit, and 1.0m high from the floor.

The above data was measured in an anechoic chamber. Please take into consideration reflected sound of your specific application environment.

3. The values given in the table for noise level reflect the levels in anechoic chamber.

NOTE: 1．Test conditions：

Cooling : Indoor: DB27℃/ WB19℃ Outdoor: DB35℃/ WB24℃

Heating: Indoor: DB20℃/ WB15℃ Outdoor: DB7℃/ WB 6℃

2．The Sound Pressure Level is based on the following conditions:

Outdoor unit：

Measure the noise value of 3 points，the points are1 meter in front of the three sides (front/left/right) of the unit surface and height =1/2(unit height +1)

meter from floor level, and calculate the weighted average of the noise.

Indoor unit：

Floor Ceiling : Test the noise value of the point 1.4m below the unit,1.0m front the unit and 1.0m high from the floor.

The above data was measured in an anechoic chamber. Please take into consideration reflected sound of your specific application environment.

3.

The values given in the table for noise level reflect the levels in anechoic chamber.

1. The above compressor data is based on 100% capacity combination of indoor units at the rated operating frequency

2. This data is based on the same conditions as the nominal heating and cooling capacities.

3. The compressor started by an inverter, resulting in extremely low starting current.

5.2 Piping length correction factor

The correction factor is based on the equivalent piping length in meters (EL) and the height between outdoor and indoor units

in meters (H).

H:

Height between indoor unit and outdoor unit (m).

• H>0: Position of outdoor unit is higher than position of indoor unit (m).

• H<0: Position of outdoor unit is lower than position of indoor unit (m).

L:

Actual one-way piping length between indoor unit and outdoor unit (m).

EL:

Equivalent one-way piping length between indoor unit and outdoor unit (m).

1.

Data above is assuming a height difference between indoor and outdoor of 0m.

2.

Be sure to minimize lenght of connection pipes in order to optimize performance. In the case that the

outdoor unit is intalled higher or lower than the indoor unit, it is necessary to apply height correction

factor additionaly to length correction factor to calculate cooling/heating. If outdoor unit is higher,

correction should be applied to cooling capacity, if outdoor unit is lower, correction should be apply to

heating capacity.

of

defrosting operation, the heating capacity is corrected by the equation below. Corrected heating capacity = Defrost

Static Pressure Setting

Setting of available of Static Pressure

The static pressure outside the indoor unit can be selected.

For AC MOTOR type:

You

can change the static pressure by changing the fan motor terminal which refer to following figure.

Note:

*:Default Settings is low static pressure by factory.

The noise under high static pressure is higher than static pressure.

For DC MOTOR type :

The static pressure can be freely adjusted by using specific wire remote controller.
