4. Insert the arm tube into the base as Figure 6. Be
sure to line up the small hole in the arm with the
holes in the base. Insert the machine screw
through the holes in the base and arm. ( if you
don’t need to power up the heater, you should
keep the power cord terminal inside the
mounting arm and this can make the installation
looks neat and tidy. You may take it out when
needed.)
