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 blower wheel (to avoid damage or bending), use a hair dryer or vacuum on blow cycle to blow debris through the element (Do not touch element).

7.Vacuum blower 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 Manual Reset Temperature Limit Control

The heater is protected by a temperature-limiting control. The manual reset temperature limit control is 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.

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 until the manual reset limit button is pressed. After allowing the unit to cool for at least 10 minutes and resolving the problem causing the limit to trip; use a narrow object such as

aball-point pen to access the manual reset button through the lower-right center section of the heater grill. Press FIRMLY and be sure to listen and feel for a click, indicating it has been reset.

Breaker trips immediately	1. Incorrect supply voltage.	1.	Verify that supply voltage matches the heater rating.
upon energizing heater.	2. Overloaded circuit.	2.	The total amperage of all heaters on a branch circuit must not be more than 80% of the
			amperage rating of the circuit breaker and supply wire ratings. Use a lower wattage heater,
			or reduce the number of heaters on the circuit.

3.A short circuit exists in the supply or heater wiring. 3. Shorted supply or heater wires may be accompanied by severe sparking. Inspect all supply and heater wiring insulation for damage. Do not reset the circuit breaker until all electrical shorts have been repaired.
