Furnace Operations Manual
Vacuum Test
1. Press the
Up
arrow button to raise the table fully up.
You cannot start a vacuum test until the table is fully up.
2. Select the
Special Functions
item.
3. Turn the
Selector Knob
to
Test Furnace
. Press the
Next
button.
4. Turn the
Selector Knob
to
Vacuum Test
. Press the
Next
button. The vacuum test will automatically begin.
There will be three, numerical indicators on the screen,
each has its own individual meaning.
• The number to the far left is the vacuum count. That
is the vacuum sensor reading.
• The second in the middle is the centimeters or inches
of mercury.
• The third is the current condition of the table
0 = moving, 99 = fully up or fully down.
5. Watch the numerical indicators as they rise.
6. The third value should stay at 99 and not change.
7. Once the vacuum has reached 240, press the
Next
button. This will place the test in the hold position
and allow you to watch for changes in vacuum value
and readings.
The acceptable loss is 2 cm or 1 inch within six
minutes.
8. Once the test has been in hold for 6 minutes, press
the
Next
button and the test will end.
9. If the numbers dropped outside the acceptable loss
range, then the vacuum system has a leak and it must
be repaired and recalibrated.
Fuses
The furnace contains two fuses:
• On the rear, just below the power cord, there are two
12 Amp (115 Vac) Slo-Blo or two 7 Amp (220 Vac)
Slo-Blo, .25 x 1.25 inch ceramic fuses.
