Important Instructions

WARNING

Turn the electrical power off at the electrical panel board (circuit breaker or fuse box) and lock or tag the panel board door to prevent someone from turning on power while you are working on the heater. Failure to do so could result in serious electrical shock, burns, or possible death.

Operation & Maintenance

How to operate your heater

1.Once installation is complete and power has been restored, turn the thermostat knob fully clockwise.

2.When the room reaches your comfort level, turn the thermostat knob counterclockwise until the heater turns off. The heater will automatically cycle around this preset temperature.

3.To reduce the room temperature, turn the knob counterclockwise. To increase the room temperature, turn the knob clockwise.

Maintenance

As needed, or every six months minimum.

1.WARNING! Before removing grill, turn the electrical power off at the electrical panel board (circuit breaker or fuse box). Lock or tag the panel board door to prevent someone from accidentally turning the power on while you are working on the heater. Failure to do so could result in serious electrical shock, burns, or possible death.

2.It is important that you verify power has been turned off and no power is going to the heater before proceeding. Circuit breakers are often not marked correctly and turning the wrong breaker off could mean electricity is flowing to the heater, even if the heater does not appear to be working. If you are uncomfortable working with electrical appliances, unable to follow these guidelines, or do not have the necessary equipment, consult a qualified electrician.

3.Once you verify the power has been turned off correctly, proceed to the next step.

4.Remove screws and take off grill.

5.Wash grill with hot soapy water and dry immediately.

6.While holding fan (to avoid damage or bending), use a hair dryer or vacuum on blow cycle to blow debris through the top element (Do not touch element).

7.Vacuum fan area without touching the elements.

8.Replace grill and secure with screws.

9.Turn thermostat to desired setting.

10.Turn power back on at the electrical panel board.

About the Heater Temperature-Limiting Controls

The heater is protected by two temperature-limiting controls (for Model CT, four controls are used). The first is a high temperature manual reset limit control, designed to open the heater circuit when excessive operating temperatures are detected. The problem must be assessed and the limit must be reset to resume operation.

Further protection is provided by a secondary over-temperature switch, which will open the heater circuit in severe over-temperature conditions, or in the event of component failure. If this occurs, the heater must be repaired or replaced.

Resetting the Manual Reset Limit Control

If the manual reset limit control has opened the heater circuit due to excessive operating temperatures, the heater will not work 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-left section of the heater grill. Press FIRMLY, and be sure to listen and feel for a click, indicating it has been reset.

Note that resetting the manual limit control may not restore heater operation if a severe over-temperature condition has occurred. See the Troubleshooting Guide on next page for more information.
