Routine Maintenance

Service Procedures

The safety valve is to be tested periodically (refer to Section 3.1, 

Periodic

Maintenance Schedule). This procedure can also be used test the optional
integral steam generator's safety valve (if applicable).

• Prevent damage during testing by ensuring that 

at least 75% of rated

pressure is in the chamber. Check current pressure level by observing
chamber pressure gauge (located behind the front access door).

• Open the try lever and hold the valve open for one to two seconds

• Allow the try lever to snap shut.

4.4.4 Safety Valve Test

WARNING - BURN HAZ-
ARD: Proper testing of the
safety valve requires the
valve to be under pres-
sure. Exhaust from the
safety valve is hot and can
cause burns. Proper safety
attire (gloves, eye protec-
tion, insulated overalls) as
designated by OSHA, is
required. Testing is to be
performed by qualified
service personnel only.

CAUTION - POSSIBLE
EQUIPMENT DAMAGE:
Actuation at less than 75%
of rated pressure can al-
low debris to contaminate
the seat and cause the
safety valve to leak. A leak-
ing safety valve must be
replaced.

4.4.5  Pressure

Regulating Valve

Adjustment

Any adjustments to this valve should be performed by a qualified service
technician. Improper adjustments to this valve may result in inadequate
sterilizer operation.
