PLA-A18EA7
4-way air flow (horizontal vane) Round duct 4-way air flow (horizontal vane) Rectangular duct
3-way air flow (horizontal vane) Round duct 3-way air flow (horizontal vane) Rectangular duct
2-way air flow (horizontal vane) Round duct
• Use 1 of the 2 duct holes on the indoor unit.
• Air flow rate of PLA-A12EA7 can be calculated from the air flow rate based on the characteristic of the duct for PLA-A18EA7.
• Use the optional air outlet shutter plate (PAC-SH51SP-E) for 3-way and 2-way air flow.
