Front Wind Baffles (WB-PA3 / WB-PA4 / WB-PA5)
General Features
- Front Wind Baffles allow outdoor units to operate at full capacity down to the temperature ranges shown in the table above.
- Prevents wind from reversing outdoor fan rotation when unenergized.
- Durable and low maintenance construction.
Please Note
- Install outdoor units with the back surface facing wall side to eliminate the effects of external wind.
- Outdoor units should not be installed in an orientation or site where the wind blows directly at the back of the unit.
- Wind baffle should not be used where there is any obstacle at either side or above the outdoor unit as the discharged air will be blocked.
- Refer to outdoor unit for detailed installation instructions.
