(45 mm) above the drogues. Stop fill process by
turning OFF s7 (SOL7).
5. Aim hose into drip pan and turn ON P2. Allow
water to flow until all air has been expelled from
HP pump and tubing.
6. Using a 2 L (0.53 gal) flask, record time to fill.
7. Turn OFF P2.
8. Connect tubing to gauge.
9. Turn ON P2. Record pressure indicated on gauge.
10. Turn OFF P2.
11. Drain SYSTEM 1E Liquid Chemical Sterilant
Processing System by turning OFF s4 (SOL4)
drain pinch valve solenoid, and turning ON P1,
circulation pump. Turn OFF P1 once water level
reaches top of drogues. It is necessary to manually
drain remaining water using a cup.
12. Turn OFF s1 (SOL1).
13. Deflate seal by turning ON s2 (SOL2). Once
deflated, tray can be re-installed and SYSTEM 1E
Processor removed from service mode.
6.4.6 LS6 Switch Test Procedure
This test procedure checks the operation of the LS6
H.P. pump monitor (pressure switch) under dynamic
conditions.
The HP pump test is found in Service Mode by
selecting TESTS, then MORE, then HPP TEST.
Selecting HPP TEST with lid closed starts an
automated sequence where the SYSTEM 1E Processor
is filled with water and the HP pump runs. The display
shows CLSD if the switch is activated or OPEN if the
switch is not activated. When the pump is running, the
switch should be CLOSED. At the conclusion of
testing, press SAVE VALUES and the unit
automatically drains and returns to the main Service
Mode menu.
6.4.7 Seal Leak Test and Compressor Output
Test
1. Connect pressure gauge to seal relief port at rear of
the SYSTEM 1E Processor.
2. In Service Mode select TESTS, then VALVES, then
turn ON s1 (SOL1), which turns on the air
compressor.
• Wait until the compressor stops running.
3. Check for leaks at fittings. No leaks should be
detected before this test is performed.
4. Turn OFF s1 (SOL1).
5. Record pressure reading on gauge.
6. Wait five minutes and record pressure on gauge. A
pressure difference of 1.0 psi or less is acceptable.
7. Turn ON s2 (SOL2) to deflate seal and remove test
equipment.
8. Turn off s2 (SOL2) when the seal has been fully
deflated and the lid latch releases.
9. If leaking, replace seal (see S
ECTION 7).
• Inspect retaining bars and corner retainers
(part of drip pan).
• Inspection should ensure there are no sharp
edges that could potentially puncture or
damage the seal during installation and or
operation.
• Any rough or sharp edges should be smoothed
out using sand paper or a file without altering
profile of retaining bars.
6.4.8 Pressure Hold Test for Housing of
MaxPure™ Filter
This test utilizes the MaxPure Filter test plug to test the
integrity of the filter housing and associated piping.
NOTE: Verify proper operation of compressor and
pressure transducer prior to performing this test.
1. Remove cap of MaxPure Filter, remove filter, insert
test plug, and reinstall cap.
2. In Service Mode select TESTS, then VALVES. Turn
ON s1 (SOL1) and s8 (SOL8) to enable compressor.
Wait until compressor stops running.
3. Press STATUS button several times until pressure
is displayed. Pressure should be between 37 and 43
psi.
4. Turn OFF s1 (SOL1).
5. Wait five minutes for pressure to stabilize, then
record start pressure.
6. Every minute for five minutes press STATUS button
until pressure is displayed and record pressure.
7. Maximum allowable pressure difference between
start and finish pressure is 0.120 psi.
8. Turn OFF SOL8 to deflate housing.
9. Turn ON s2 (SOL2) to deflate seal and remove test
equipment.
10. Turn OFF s2 (SOL2) when the seal has been fully
deflated and the lid latch releases.
