WARNING – PERSONAL INJURY AND/OR
EQUIPMENT DAMAGE HAZARD: Repairs
and adjustments to this equipment must be made
only by STERIS or STERIS-trained service person-
nel. Nonroutine maintenance performed by
unqualified personnel or installation of unautho-
rized parts could cause personal injury, result in
improper equipment performance, void the war-
ranty or result in costly damage. Contact STERIS
regarding service options.
WARNING – ELECTRIC SHOCK AND/OR
BURN HAZARD: Disconnect all utilities to
unit before servicing. Do not service unit unless all
utilities have been properly locked out. Always
follow local electrical codes and safety-related
work practices.
6.1 GENERAL
Each unit must be tested and inspected according to
this procedure whenever a part is adjusted, repaired
or replaced. Items which do not comply to test proce-
dures must be corrected and retested.
Keep record of all readings, measurements, discrepan-
cies, corrections, tests and reinspections. Each test
must meet the standards of material and performance
set forth in this procedure. Refer to S
ECTION 7, COM-
PONENT REPAIR AND REPLACEMENT, should mechanical
problems arise or adjustment be required.
Read the complete test procedure carefully to know
steps to be accomplished and test equipment required
before starting.
6.2 TEST INSTRUMENTATION
REQUIRED
• Stopwatch — to verify cycle phase timing and
injection times.
• Calibrated pressure gauge 1/4" NPT 0-160 psi
(0-1100 kPa).
• Calibrated pressure gauge 1/4" NPT 0-20 psi
(0-138 kPa).
• Digital potentiometer with 2 thermocouple exten-
sions.
• Multimeter (voltage, amps, ohms).
1. Place 0-160 psi pressure gauge on pressure piping
above pressure transmitter.
2. Place 0-20 psi pressure gauge on suction piping
upstream from self cleaning screen.
3. Place one thermocouple on a load in the middle
of wash chamber and the other one at the inlet of
the exhaust duct inside wash chamber (if drying
system option is present).
6.3 PRELIMINARY CHECKS
1. Verify proper hookup of electric and water sup-
plies.
2. Inspect all piping clamps and tighten if necessary.
3. Verify all electrical devices (valves, sensors,
switches, control) are connected.
4. Clean sump screen inside wash chamber and self-
cleaning screen on service side.
6.4 OPERATIONAL AND SAFETY TESTS
WARNING – PERSONAL INJURY AND/OR
EQUIPMENT DAMAGE HAZARD: To open
doors from inside wash chamber, pull EMER-
GENCY STOP cables. Washer operation will auto-
matically stop. Then, push firmly on door panel
using shoulder and upper arm, applying upper
body force.
Open all utilities (air, hot water, cold water, steam),
put electrical disconnect switch to ON position.
1. Control should now be in Automatic Mode and
display Main Cycle Menu.
2. Open door(s) (if not already open).
3. Inside chamber, pull left EMERGENCY STOP
cable. Control and all outputs should be de-ener-
gized.
4. Replace left EMERGENCY STOP cable. Control
should be re-energized and display should show
Main Cycle Menu.
IMPORTANT: A listing of the Safety Precautions to be observed when operating and servicing these
washers can be found in S
ECTION 1 of this manual. Do not operate or service the equipment until you
have become familiar with this information.
