PARTS OF YOUR HEATER

This heater is for use with 240 volts. The cord has a 20 amp or 30 amp plug

as shown in Figure 1. No adapter is available for these blade congurations,

and none should be used. The Hot One requires a 240 volt grounded

receptacle. When properly installed, it provides a ground connection through

the cord to the heater to protect the operator from electric shock. Do not use

an extension cord, power strip or any kind of adapter.

RESETTING THE MANUAL RESET LIMIT CONTROL

About the Manual Reset Temperature Limit Control

The heater is protected by a high temperature manual reset control, designed to open the heater

circuit and stop the electrical current ow when excessive operating temperatures are detected.

Resetting the Manual Reset Temperature Limit Control

If the manual reset limit control has opened the heater circuit due to excessive operating

temperatures, the heater will not work or may blow cold air until the limit reset button is pressed. After

allowing the unit to cool for at least 10 minutes and resolving the problem causing the limit to trip

(typically the heater is blocked or needs cleaning); use a narrow object such as a ball-point pen to

access the reset button through the lower-right hole marked “RESET”. Press FIRMLY. If the manual

reset continues to trip, see Troubleshooting Chart.
