Door frame heaters shown in Figure 18 may now be
replaced.
During installation, the white portion of the heater
should not come in contact with itself. The heater
should be installed so that only one white portion of
the wire enters the raceway. The other portion entering
the raceway will be the black lead wire.
Once the heater wire is connected, check resistance
(ohm reading) before replacing wireway covers. This
will ensure that heater wire was not broken during
installation. Wiring diagrams are shown in Figure 19.
After covers are reinstalled, turn power on and verify
that heaters are working properly.
— LOCK OUT / TAG OUT —
To avoid serious injury or death from electri-
cal shock, always disconnect the electrical
power at the main disconnect when servicing
or replacing any electrical component. This
includes, but is not limited to, such items as
doors, lights, fans, heaters, and thermostats.
