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.
