SAFETY PRECAUTIONS SUMMARY
Observe the following safety precautions to ensure safe operation of the
sterilizer.
a. Door Operation with Liquid Cycle.
(1) Allow ample cooling time to prevent possible thermal shock or liquids
boiling over when the door is opened or when the load is removed. When the cycle is
complete, check that the chamber pressure gauge is at zero.
(2) Wear an elbow length heat resistant glove to protect against escaping
residual steam when lowering the verti-glide door.
b. Emergency Manual Gasket Retract Procedure. To remove a load from the
chamber when an incomplete cycle results from a power interruption to the unit, ensure
that the chamber reading is at atmospheric reading and de-energize the unit.

OPERATION CHECKOUT PROCEDURE
Now that you know the functions of the entire unit, you will use this knowledge to
perform an operational checkout. Perform the following procedures to verify that the
sterilizer is working properly, against a known standard.
a. Turn on the power at the wall box.
b. Ensure CB1 and CB2 are on by checking if the green lights above them are
on. This indicates that 120vac is present.
c. Ensure that the door is open. If not, flip the control board to MANUAL and
energize SSR number 5. It may also be necessary to energize SSR number 14 if there
is a vacuum in the chamber.
d. Ensure that DS1 on the control board and DS18 on the display board are lit.
This indicates that 18 volts direct current (vdc) and 5vdc are present.
NOTE:
Any light emitting diode (led) that appears dimmer than normal could indicate
a power supply problem.
e. Ensure that the control on (display board) is on and the door unsealed and
exhaust lights are on. The exhaust light may or may not be on. If the unit did not have
power to it, the exhaust light will come on. If the unit was just off, then the exhaust light
will not come on. The door unsealed light will come on. The exhaust led only comes on
after the incoming power has been interrupted.
