Wiring of the German
Fan
Step by step wiring instructions
for the German fan. This procedure follows the
mounting of the
fan. Mount the fan first, then place the thermstat where it will
be
sensing the hottest air, away from the fan and higher as shown
here.
Before you mount the thermostat, and you have several vent locations to
mount the fan,
Proper placement would mean opposite of where the coolest air
is to draw in. The
best is the North side. Second best is the
East side. You don't want to use a South or
West vent as an intake vent
as solar heated air can rise up the wall via convection and
be drawn into
the vent. Now you are bringing in hotter air than it is outside.
Install on a
West or South facing vent if possible. This only
applies to gable mounted fans, not roof
vents.
Mount the box with a hammer. The nails are already in
the box
Remove the plastic adjustment
knob and plastic face plate and set aside
Remove the thermostat assembly with
small phillips screwdriver (bring a straight just in case)
SLOWLY remove the
thermostat because it's already wired to the fan
Let the thermostat hang and bring
your romex cable in. 14gauge is recommended.
Put a "Z" into as shown as
your strain relief. If someone trips over your power line
this shape
helps prevent it from breaking the connection.
I know this looks really
confusing but look at it closely...
..."there's six wires! What if I
burn the house down?" Let's take this step by step.
The wire at the top
of the box is the wire we install when we ship it to you. The
wire,
the box, the fan are all
connected. We have
already connected (the two black wires
above) with the
yellow wire nut. Now, throught the process of elimination, you do
the
obvious first: connect the two bare copper ground wires. That's two out of
six
done. Now, with the wire nuts we have provided, connect the two
white wires together.
That's four out of six connected. There are only
two left. Connect them.
This is how it should look when
you are done.
Ground (bare copper) to ground
White to White
Your
black romex wire to the red thermostat wire.
Congratulations! Set the fan so it doesn't run all
night.
Push the wires into the base of
the blue junction box. At this point you are going
to be installing the thermostat to the junction
box. The post you see is not in the
center of the face panel,
it's towards the top. While it will work upside down
(and
I realize the attic is hot and
cramped), putting it right side up is the right thing to
do.
Finished
installation. VERY IMPORTANT!!! This installation is not
complete. There
should be no openings anywhere near the
fan. The negative pressure created behind
the fan will just draw the
air in around it. It's the path of least resistance.
