King Electric Model KTW - Manual (Page 3)

Table 3
This heater is equipped with a thermal overload
called Smart Limit Protection. It disconnects ele-
ments and motor in the event normal operating
temperatures are exceeded. If the thermal overload
trips due to abnormal operating temperatures, the ther-
mal overload will remain open until manually reset by
turning the heater OFF for fifteen minutes. Inspect for
any objects on or adjacent to the heater that may cause
high temperatures. After inspecting the heater, keep
the power to the heater off for 10 minutes to reset the
SLP thermal protector. If the SLP thermal protector
shuts the heater off again, immediately turn the heater
OFF at the circuit breaker and inspect the heater for
possible fan motor failure or dirt and lint on the heating
element. Repeat the starting procedure.
General information and Guidelines:
This heater must be properly installed before it is used.
DO NOT tamper with or change the operating of this
heater. If replacing components only use King approved
replacement parts. No other parts are an equal.
OPERATING INSTRUCTIONS
KTW Toe and Space Heater
3
Operation:
1. After the electric heater has been completely in-
stalled, all thermostats should be turned to LOW or
NO HEAT. Turn ON breaker, wait 3 to 5 minutes and
check to see that the heaters are not operating. If
operating, disconnect power and check for improper
wiring. If none are operating then turn thermostats
to highest position and wait 3 to 5 minutes. Check to
see that all heaters are operating. Should any not be
operating, disconnect power and check wiring.
2. Allow entire system to operate steadily for 1/2 hour.
This should remove oily residue from manufacturing.
(Some smoking may occur).
3. Select the setting for comfort on all thermostats.
4. A safety limit control is provided to turn off the
heater automatically if it is blocked or otherwise
overheats due to an abnormal condition. DO NOT
bypass or remove this safety device from the electri-
cal circuit-see Warning Figure 3 on page 2. During
normal use, this safety control should not operate. If
you find that this control is operating, make sure the
heater is not being blocked. If it continues to cycle
the heater off, Check that you have the proper volt-
age, disconnect power to heater and have it
checked and or repaired by an electrician.
