Operation Instructions
HEATER MAINTENANCE
SOFTHEAT has no moving parts to wear
out, so it is virtually maintenance-free.
However, it is recommended to periodi-
cally remove the front cover (UNPLUG
UNIT FIRST) and vacuum the lint or
dust from the inside of the heater to
maintain peak heat transfer into the air.
Use caution when vacuuming to avoid
damaging the aluminum fins.

Please note: If your heater has a thermostat control knob that is labeled with an "OFF" position, the unit
is equipped with a double pole thermostat. No heating will occur when the thermostat is rotated to the
full counterclockwise "OFF" position.

How Softheat hydronic baseboards work:
Inside a Softheat baseboard, a hermetically sealed water and
anti-freeze solution is heated by an electric heating ele-
ment. As the solution is heated, warmth is generated and
transmitted through dozens of aluminum fins along the
heater tube (it could initially take 30 to 60 minutes to warm a
room, depending on the room size). As the warmth spreads
outward from the heater, cooler air from the floor and wall nat-
urally flow toward the base of the heater. "Convection air heat-
ing" (See Figure 3) provides heat without fans, preventing the
heater from blowing or burning dust particles. The room is
warmed with even, comfortable heat without cold and hot
spots throughout the room. While Softheat offers everyone
a comfortably warm room, it was specifically designed to
