Operational Information
The DeWalt Electric forced air heaters are designed to be used by professionals.
Heat is created by electric current passing through coiled metal elements bringing them up to very high temperatures. The fan then passes room air over the hot elements
exchanging cold air for warm.
The air moving over the coils keeps them from reaching temperatures that are not safe for the normal operation of the heater. However it is important to keep all combustible
materials and any objects that may be sucked into the fan blades at a safe distance (please refer to the table on the next page for appropriate distances). Make sure that the fan
blades remain unobstructed at all times.
Keep unit clean and dust free. Do not block unit intake or exhaust at any time.
Review and understand all warnings in this manual. Follow all local codes.
This unit is designed to be used with 115v ac only.
This unit is supplied with the appropriate (NEMA 5-15P) plug. Do not use any plug other than the one supplied by the manufacturer.
If damage has occurred please refer to the parts listing in this manual and contact the manufacturer for a replacement.
This unit is designed to be used with a properly grounded NEMA 5-15 outlet only (show on the right).
Operation
WARNING: Outlet must be properly grounded, failure to do so may result in electric shock.
