Operation
WARNING: This heater is factory prewired for operation
with the built-in thermostat. THIS HEATER IS NOT TO BE
USED WITH A REGULAR WALL THERMOSTAT.
CAUTION: This heater must be properly installed before
it is used.
The PCH is a Precision Comfort Heater, which maintains a
constant room temperature through the continuous addition
of heat by the blowing of air into the room based on the
setting of the thermostat. The PCH operates such that once
the room reaches the set point, the fan and heater will
continuously run at a low level, to maintain the desired
room temperature. If the temperature in the room rises,
i.e. sun coming through a window, the fan will slow further
and the temperature of the heater will reduce so that the
temperature of the room will continue to be the same.
!
NOTE: The element retains heat after shutdown, there
is a built in cool down period of 2 ½ minutes before the fan
shuts off completely.
WARNING: Should the Over Temp light come on,
disconnect power to the heater and call a licensed
electrician. DO NOT USE HEATER UNTIL THE CAUSE
OF THE PROBLEM IS DETERMINED AND FIXED.
