11.1  To test, let vessel cool for 10 minutes if hot.
Refill vessel to proper water level, turn Function
Switch to Dryer 'OFF' position, turn Timer and
Power Switch 'ON' and rotate Autoclave
Temperature Control to highest setting. If the
Temperature Pilot Light is 'OFF' connect an AC
Voltmeter across T.B. Terminal #2 and T.B.
Terminal #4. Full line voltage should be present. If
not, see Sections #3, #4, #5 and #6. Now move
meter test lead from T.B. Terminal #4 to T.B.
Terminal #5. Full line voltage should be present
while vessel is in  its' initial heating stage before
pressurization. If line voltage is not present at T.B.
Terminal #5, replace Autoclave Temperature
Control. See Section 17. If this is a new control,
ensure one wire is connected to 'Common' and
the other wire connected to the 'N.C.' (normally
closed) contact on the controller.

11.2  Allow vessel to continue heating until
maximum temperature and pressure are
readched, If pressure goes above 30 PSI or
controls at less tan 27 PSI at maximum setting,
go to Section 12 to attempt adjustment. If
controlled pressure fluctuates more than 2 PSI
from set point after one hour, replace Autoclave
Temperature Control. See Section 17.

12.0  AUTOCLAVE TEMPERATURE CONTROL
ADJUSTMENT:

12.1  While vessel is under pressure in autoclave
cycle, loosen the two set screws in the control knob
and remove knob. Set the control knob shaft so
that the Autoclave Temperatuer Conteol regulates
at 27 PSI ± 1 PSI/133°C±1°C. If pressure/
temperature is high, turn shaft clockwise. Allow
controller ample time to reach set point after
making an adjustment. If pressure varies over 2
PSI or fluctuates inconsistently, the control should
be replaced. See Section 17.

12.2  Once the control is properly adjusted at 27
PSI ± 1 PSI, place control knob on shaft. Turn
knob counterclockwise untiil knob reaches stop.
Now tighten knob to control shaft.

12.3  Turn Control Knob fully clockwise. allos
ample timer for vessel to cool and be controlled at
low set point. Pressure should drop to at least 15
PSI and control ±1 PSI. If Controller will not do
this, it should be replaced.

13.0  HEATING ELEMENTS:  Autoclave and Dryer
Elements. Unplug unit from electrical outlet.

13.1  To test Dryer Element (Top Element), remove
both wires from the Dryer Element terminals on
top of the vessel. Connect an Ohmmeter across
the two element terminals. The Dryer Element
should measure 11.5 ohms ± 0.6 ohms on 120V
Elements or 46 ohms ± 3 ohms on 240V Elements,
if not, replace Element. See Section 18. Now
conduct test in Section 13.3.

13.2  To test Autoclave Heating Element (bottom
Element), remove bottom access cover and
remove both wires fromthe Heating Element
terminals. Connect an Ohmmeter across the two
Element terminals. The autoclave element should
measure 10.3 ohms ± .6 ohms on 120V Elements
or 41 ohms ± 3 ohms on 240V Elements. If not,
replace Element. See Section 18. Now conduct
test in Section 13.3.

13.3  Now select highest resistance range on
Ohmmeter. Touch one test lead to either terminal
on Element on touch other test lead to the vessel
body. This test will give an indication whether or
not the Element is shorting to ground. Do not touch
ends of test leads with hands. If you get any meter
indication less than infinity, replace Heating
Element. See Section 18. Replace wires to
Element when test is completed.

14.0  DRYER TEMPERATURE CONTROL: This
is an infinite control which varies the 'ON-OFF' rate
and current 'ON' time which is being supplied to
the Dryer Heating Element. The rate/time interval
is a function of the Dryer Control Setting.

14.1  The Dryer Temperature Control has 5 wire
connections labeled; P, L-1, L-2, H-1 and H-2.
Connections L-1 and L-2 are the power input point.
Connections  H-1 and H-2 are the power output
points which lead to the Dryer Element. Connection
P supplies power to the Dryer Pilot Light when the
Dryer Temperature Control is turned ON.

14.2  To test Dryer Temperature Control first test
Dryer Heating Element as in Section 13. Now turn
Timer, Power Switch and Function Switch 'ON'.
Connect an AC Voltmeter across the two Dryer
Temperature Control contacts labeled 'L-1' and
'L-2' to ensure power is present at Controller
inputs. If line voltage is not present, see Sections
3, 4, 5 and 6.
