7. Preliminary Start-Up
After plumbing is completed, conduct the following test to
determine if there are any leaks in the system.
CAUTION: On the E992 unit deionized or regular water must be
connected to the secondary solenoid or damage will result to the unit if
no water enters the tank during the second rinse cycle.
A)
Turn main power ON
B)
RUN-STOP switch must be ON
C)
Close cover
D)
Turn selector switch to FILL
Push START button and hot water should enter the tank. The unit
has a flow control valve, which allows 5.0 GPM, so it is important that
the shutoff valve does not restrict the flow to less than 5.0 GPM or the fill
time will have to be increased.
After 150 seconds (or other programmed fill time), the fill solenoid
will close, and the water will be up to the overflow drain opening. At this
time, shut main power off, disconnect electrical plugs from outlets, open
cabinet, and check for leaks.
Leave selector switch in FILL position, push START, and hot water
will enter the already full tank and begin to cascade through the overflow
drain. After 150 seconds, the FILL solenoid will close.
If no leaks are detected, connect power, turn main switch ON,
move selector switch to CLEAN, push START, and the cleaning cycle will
begin.
After the ultrasonic cleaning step, the tank will drain (with pump).
When the tank is empty (after 150 seconds) shut main off, disconnect
power, and check for leaks in drain-pump line.
If no leaks are detected, connect power, turn main ON, and
program will complete to finish. Check at each fill stage that water is
coming into tank.
8. Operation
The basic principle of operation is the enhancement and
acceleration of the cleaning action through ultrasonic cavitations.
Instruments or parts to be cleaned are placed in the basket (or cassette
racks) and lowered into the tank.
NEVER PLACE PARTS DIRECTLY ON THE BOTTOM OF THE TANK.
The baskets and cassette racks, that can be purchased from ESMA Inc.,
have rubber supports to keep parts off bottom of tank.
