OPERATION INSTRUCTIONS:
Only attach heater to 300 CFM Blower Fan unit. Slide the heater over the blower outlet and
secure the spring clip to the blower catch. The fit should be tight with no gaps.
TO OPERATE:
Plug the heater power cord into the blower receptacle. TURN THE BLOWER ON FIRST and
then turn on the heater with the lighted On-Off switch. When the switch is lit, the power is ap-
plied to the heater.
TO SHUT OFF:
TURN THE HEATER OFF FIRST and then wait a few minutes before turning off the blower. This
allows the heater to cool down and extends the life of the heater unit.
TO DISCONNECT:
To disconnect heater, turn heater control to off, remove heater plug from blower receptacle, and
uncouple heater from blower outlet.
CONTROLS:
1) Lighted On-Off Switch: Lit when power is applied to the heater.
2) Air Switch: Provides an interlock so the heater can only be operated after being mounted on
a blower and the blower is normally operating.
3) Internal Thermostat: An internal thermostat has been provided to maintain the heater
temperatures within normal operating ranges.
4) Power Indicator Light: Lit when the heater is normally operating.
5) Internal Thermal Fuse: If the thermostat should fail or the temperature of the heater starts to
reach a hazardous range, a one time thermal fuse protects against hazardous over-
thermostat conditions. This fuse is set to trip above the thermostat set point and is a factory
replaceable item.
