the Controller for
Damage
Carefully inspect your controller as soon as it arrives.
If it is damaged, call your dealer. Then notify the freight
agent at once and request an inspection. Save all pack
ing materials for inspection by the freight claims ad
juster. Refer to your packing list for more information.
INSTALLING THE
PORTABLE P 2000
If you purchased a furnace with a UDC
2000
control
ler already installed, skip this section. This section
applies only to the P
2000,
which is a portable UDC
2000
controller.
1.
Position the P
2000
far enough away from your
furnace to avoid heat damage.
2.
Install the thermocouple on your furnace. (The ther
mocouple is the temperature-sensor rod with ceramic
insulators on it.) First, decide which vent hole (also
called peephole) to use. Find a
112"
vent hole on your
furnace. Most four-sided furnaces have a vent hole in
the top, the door, and the back. The hole in the back
would be the best choice, but you could use any of the
others, too. If your furnace, by chance, has no vent hole,
drill one. Drill a
112
hole in either a row of blank bricks
.
or at the seam line where two rows meet. (This is to
avoid drilling closer than
1"
to an element.)
If your furnace or kiln has two holes, one above the
other, use the top hole for the thermocouple. If your kiln
has only one peephole, you will need to drill a separate
hole for the thermocouple, because you should always
have one for viewing the firing chamber.
If you are mounting the thermocouple in a kiln with
tapered peepholes (where the outside of the hole is
larger than the firing chamber side), insert the ther
mocouple into the drilled peephole plug provided. Place
plug into the top peephole of your lr.iln.
You will need to
bend the ther
mocouple at a
90·
angle so that you
can fasten the
t h e r m o c o u p l e
block
·
to the out
side kiln case. To
bend, first break
off one of the
ceramic insulators
squeezing with pliers.
Then bend the thermocouple where it Will extend into
the firing chamber by
1
-
11/2"
when the thermocouple
block is pressed against the outside
kiln
case. Hold
thermocouple with pliers when bending.
5.
Position outer part of thermocouple sideways or
downwards against the kiln case. (Avoid placing the
thermocouple block above the peephole, which would
expose it to heat rising from the peephole.) Place the
thermocouple holddown bracket over thermocouple
INSTALLING THE PORTABLE P 2000
block and drill two
1/8
holes. Fasten with screws
provided.
Do not fire kiln without holddown bracket in place,
because your kiln will overfire if the thermocouple
should fall out.
6.
Plug your kiln or furnace into the P
2000.
7.
If your
kiln
has switches, turn aU switches to the On
or High position. Leave all your kiln's switches on full
when firing your kiln with the P
2000.
If you're using a kiln sitter or limit timer
as
a back
up shut-off for the
P
2000,
place a cone in the kiln sitter.
Set the limit timer for half an hour longer than expected
firing time. It will be necessary to use a new cone for
every firing even if the previous cone didn't bend.
9.
If you decide not to use the kiln sitter or limit timer
as a back up shut-off, disconnect limit timer. Raise the
kiln sitter weight, press in the plunger, and gently lower
the weight. Your
kiln
sitter is now on manual control.
Do not use the firing gauge to lock the kiln sitter weight
in the up position, for this could damage the kiln sitter.
