Mechanical Timer
START-UP
1. To start your machine set your timer (item 1) to the pre-set
time (item 2) desired for ultrasonic cleaning. The machine will
automatically shut itself off at the end of the pre-set time.
2. Machines equipped with heat have a separate “On-Off” rocker
switch (item 3) located on the front panel. Pushing this switch
to the “On” position allows pre-heating of cleaning solution
prior to turning on the machine. The rocker switch is lit when
the heater is on and must be pushed to the “Off” position
when the heater is not in use.
3. The heater is designed to maintain the temperature of the
cleaning solution between 125°-150°F (52°– 65C°). When you
operate both the ultrasonics and heat simultaneously with the
tank covered for an extended period of time, the solution tem-
perature will rise above this level. At this point, the thermostat
will automatically shut the heater element off until the solution
drops below maximum heat level. The thermostat will be reac-
tivate as required. During this cycle, the heat indicator light will
remain lit. Because of the intense ultrasonic power dissipated
in the form of heat, the temperature of the solution may once
again rise above 150°F with the ultrasonics operating.
The heat rocker switch must always be turned off
manually. This switch does not turn off automatically.
