Instructions for
Ultrasonic Washer
E397 & E397RC
E498 & E498RC
1. INTRODUCTION
The E397 and E498 units automatically perform a cleaning cycle, the major steps of which are:
Ultrasonic Cleaning
Ultrasonic rinsing (hot tap water)
The result is a finished product ready for the next step (sterilizing packaging, assembly, storage).
The unit consists of two sections: 1) Tank cabinet to be installed in the counter and 2) Control Plate to be
installed on front of counter. (Models 397-RC and 498-RC). The tank size is 14quart for Model E397 and
15quart for Model E498.
The tank is manufactured from 316 stainless steel with six potting transducers mounted on bottom. The
cabinet is manufactured from 304 stainless. The unit contains a self-tuning modular circuit board, a high
velocity fan to cool the electronics and a RFI filter to eliminate high frequency noise. A programmable
controller automatically runs the fill and drain solenoids and cleaning cycle.
The control plate contains the main and the start switches and several process indicator lights. The controls
also can be installed on the top plate of tank cabinet.
PLEASE READ THESE INSTRUCTIONS THOROUGHLY BEFORE INSTALLATION AND OPERATION. CALL
[phone] IF YOU HAVE ANY QUESTIONS.

2. INSTALLATION
Tank Cabinet - cut opening of 16” wide X 15” depth in top of counter. The overall flange of unit on top of
counter is 18 ¾” wide X 18” deep, so center unit accordingly. Secure unit to counter with 8, #10 stainless
wood screws supplied. Also, 19 inches of clearance is necessary under the counter.
Control Plate - Cut opening of 4 ½” X 4 ½” in front of cabinet or other convenient place. The overall flange of
control plate is 5” X 6” wide. Plate will be mounted with 4 no. 8 stainless wood screws supplied. If the
control plate is to be placed directly in front of the tank cabinet, allow
3 ½” between counter opening and front of cabinet. If this is not possible because of cabinet design, the
control plate can be positioned on either side of unit.

3. PLUMBING (see figures 1 and 2)
A. Water Input
The primary solenoid (A) should be connected to a hot water source. The solenoid has a ¾” fitting for
connection to high pressure hose. The high pressure hose should connect the solenoid to a shut-off valve
(not supplied) at your water source. A filter washer is incorporated into the high pressure hose which acts
to prevent sediment in the water line from clogging the primary solenoid.
Also, a back flow regulator (not supplied) may have to be attached at your water source to comply with
local regulations.
B. Water output
1. Drain
The drain solenoid (B) is fitted with a hose barb fitting to accommodate a ¾ inch ID hose. The ¾”
hose can be connected directly to a dishwasher attachment with a ¾” input under an available sink
or to another suitable drain. A clean out strainer (C) has been installed prior to the drain solenoid to
prevent debris from clogging the solenoid. This cleanout can also be used to manually drain the tank
should it become necessary.
2. Overflow
Located in the tank is an overflow nipple that allows water to cascade during ultrasonic rinsing. A ½
hose barb (D) found on the bottom of the unit must be tied into the drain line prior to connection to
the dishwasher attachment.
4. ELECTRICAL
The unit is rated at 350 W, 120 VAC, 50/60 HZ. The unit is fused at 5 AMP, 250 VAC with a replaceable fuse
located underneath the unit. The power cord must be connected to a three-way grounded outlet.

The control plate cord needs to be plugged into the mating receptacle located underneath the unit. (see figure
1)
5. PRELIMINARY STARTUP
After plumbing is completed, run through a cycle to make sure there are NO leaks. Caution: Do NOT
operate unit if no water enters the tank or damage could result to the electronics.
Procedure:
1. Turn main power ON.
2. Place cover on the tank to reduce any splashing during initial start-up.
3. Push start button and water will enter tank and the cycle will proceed as follows:
Function Time/Seconds
A. Fill 120
B. Ultrasonic Cleaning 600
C. Drain 180
D. Fill 120
E. Ultrasonic 60
F. Ultrasonic/rinsing 60
G. Ultrasonic 60
H. Ultrasonic/rinsing 60
I. Ultrasonic 60
J. Drain 180
K. Buzzer 5
Total 1,505 (25 minutes)
If the main power is turned off during a function, the process will continue in that function when the power is
turned back ON.

If no leaks are found begin cleaning procedures.
6. RUN – STOP SWITCH
A RUN-STOP-SWITCH is located underneath unit.(Figure 1) The switch must be in the RUN position at all
times for the programmable controller to operate. If for any reason during the program cycle you want to stop
the process, turn switch to stop position and the program cycle will discontinue. Move switch back to RUN
position and program will START over at the beginning of the program when start button is pushed.
Use RUN-STOP switch only for emergency stopping of unit.
7. 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.
Add a few tablespoons of cleaning agent to tank either before or after basket with parts is lowered into tank.
Put on tank cover and push start button to begin process.
8. WATER CONSUMPTION
In the program 3 gallons of water are used on the initial fill cycle with an additional 6 gallons used in the fill-
rinse steps, D to H for a total of 9 gallons of hot water used per cycle.

If any changes in the rinse programs are required, consult the manufacturer.
9. CLEANING AGENT
It is recommended to use a liquid cleaning agent because some powders take too long to go into solution.
ESMA has a liquid cleaner, E589 where it is recommended to use 2 to 4 tablespoons per tank load.
Some general purpose detergents may be all that is required to clean your items. Depending on types of parts
and debris to be removed, some experimentation will be required with type of cleaners and concentrations.
Remember, adding too much cleaning agent can cause a problem with final rinsing of parts if too much suds
are generated.

10. MAINTENANCE
Periodically, the screen in the lint trap located underneath the unit before the drain solenoid will have to be
cleaned out. The accumulated lint and debris could slow down the draining sufficiently so tank will not be
emptied of cleaning solution before rinse cycle starts.
The unit is manufactured of 316 and 304 stainless steel. Clean with a commercially available cleaner for
stainless kitchen appliances.
