About the Marley K4843A
The K4843A is a complete K Series (Model A) fan-forced wall heater from Marley. It uses a built-in fan to deliver heat into the room.
This unit is rated 4800W at 240V, three-phase. Make sure your building's supply voltage and phase match these ratings before ordering.
Don't use the heater anywhere flammable liquids such as gasoline or paint are used or kept, or in corrosive settings like marine, greenhouse or chemical-storage areas. Keep the air intake and outlet clear, and do not install it behind doors, furniture, towels or boxes.
Installation Tips
Turn off power at the main disconnect panel before installing or servicing. Wiring must follow national and local electrical codes, and the heater must be grounded. Confirm the supply voltage matches the heater's nameplate before turning it on. Installation by a qualified electrician is recommended.
