WHFC CEILING HEATER
This heater includes a manual reset thermal protector with a self
hold feature. If the heater shuts off with the thermostat in the on
position and the room temperature is below the highest thermostat
setting, immediately disconnect the power to the heater at the
circuit breaker and inspect for any objects on or adjacent to the
heater that may cause high temperatures. After inspecting the
heater keep the power off to the heater for 10 minutes to reset the
thermal protector. If the heater 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 starting procedure.
INSTRUCTIONS
It is extremely important you verify the electrical power supply is the same voltage as the heater you are installing.
240 and 120 Volt heaters are not interchangeable. Powering a 240 Volt unit with 120 Volt supply wires will reduce
the heater output by approximately 75%. Powering a 120 Volt unit with 240 Volt supply wires will destroy the heater
and voids all warranties.
CAUTION: Turn off power source supplying the heater before attempting any installation, maintenance,
or repairs. Lock or tag circuit breaker or fuse panel door. Failure to do so could result in serious electrical
shock, burns or possible death.
Ceiling Installation: King recommends this ceiling heater be installed adjacent to outside walls to direct warm air fl ow
toward outside walls. The heater should be operated with a quality wall thermostat - for optimum performance locate
thermostat on an inside wall. Heaters should be placed a minimum of 6 feet from the fl oor and a minimum of 16"
from any adjacent vertical wall surface. Heater may be installed 12" above doors. Do not install where any combustible items will be within 24" immediately below the heater.
