b. Cooling only unit (INVL type) has no items on heating;
c. Noise was tested in semi-silenced room, so the actual noise value will be a little higher for change of ambient.
d. The charge amount of R410A in the list is only the sealed amount when outdoor unit outgoing. When installing,
calculate the additional charge amount according to actual length of pipe and the matched indoor units;

Note:
a. The data will change with the change of products. Refer to those parameters listed on nameplate.
b. Noise was tested in semi-silenced room, so the actual noise value will be a litter higher for change of ambient.
c. The charge amount of refrigerant in the list is the datum when there is not drop height vertically between indoor unit and
outdoor unit, without consideration of connection pipe. So calculate the additional charge amount according to actual
condition during installation.
d. Section area of lead wire is only applicable for 15-m distance.If above, increase the section area to avoid overload of
current which would cause burnout of lead wire.
e. The outdoor fan of this unit is without static pressure.If static pressure is required, please specially notice it on purchase
order.
f. Running condition of cooling : outdoor tem -5℃～48℃; running condition of heating: outdoor tem-20℃～27℃.

a. The data will change with the change of products. Refer to those parameters listed on nameplate.
b. Noise was tested in semi-silenced room, so the actual noise value will be a litter higher for change of ambient.
c. The charge amount of refrigerant in the list is the datum when there is not drop height vertically between indoor unit and
outdoor unit, without consideration of connection pipe. So calculate the additional charge amount according to actual
condition during installation.
d. Section area of lead wire is only applicable for 15-m distance.If above, increase the section area to avoid overload of
current which would cause burnout of lead wire.
e. The outdoor fan of this unit is without static pressure.If static pressure is required, please specially notice it on purchase
order.
f. Running condition of cooling : outdoor tem -5℃～48℃; running condition of heating: outdoor tem-20℃～27℃.

a. The data will change with the change of products. Refer to those parameters listed on nameplate.
b. Noise was tested in semi-silenced room, so the actual noise value will be a litter higher for change of ambient.
c. The charge amount of refrigerant in the list is the datum when there is not drop height vertically between indoor unit and
outdoor unit, without consideration of connection pipe. So calculate the additional charge amount according to actual
condition during installation.
d. Section area of lead wire is only applicable for 15-m distance.If above, increase the section area to avoid overload of
current which would cause burnout of lead wire.
e. The outdoor fan of this unit is without static pressure.If static pressure is required, please specially notice it on purchase
order.
f. Running condition of cooling : outdoor tem -5℃～48℃; running condition of heating: outdoor tem-20℃～27℃.

Notes:
① The design of this unit comply with the national executing standard of GB/T 18837-2002;
② Refer to the product nameplate for parameters and specification of the unit;
③ The model with INVL code is cooling only unit; while the model with INV code is heat pump unit; the cooling only
units dose not have any parameters of performing heating;
④ The sound level is tested under circumstance of semi-anechoic chamber; the value of noise could be a little higher in
actual operation.
