Tank Heater Protection
A ball float pressure switch is located in the wash tank. The
power supply will be automatically off under low water level.
Once the water returns to a safe level, the heater will be
1
activated when needed. An overheated protector is also
provided for electric heater. If overheat should occur, the
power supply will be turned off automatically. Turn the POWER
switch OFF when overheating happened and contact the local
authorized service office.
Booster Heater Protection
The booster water temperature is regulated by the thermostat
to keep the rinse water temperature on 82-90℃. The thermo-
stat is preset at the factory and no adjustment should be
required. When rinse temperature is not sufficient, please turn
off the power and contact the local authorized service office.
Booster main power circuit protection
To ensure normal operation of booster heater, a circuit breaker
is set in the control box. When overheating or short circuit
happens in main circuit, the circuit breaker will automatically
trip off the power.

Door Interlocks
Door interlock switches will prevent machine operation while
an inspection door is open. If a door is open while the machine
is operating, the pumps and conveyor will automatically stop
working. After the door is closed, the machine must be
restarted by pushing the WASH switch to ON.
Auto Fill
Close door (s) and push the POWER switch to ON. The
machine fills automatically after 5 seconds. Water is heated in
booster, and then flows into wash tank. After the tank is filled,
the solenoid valve is closed automatically.
Auto Timer
The Auto Timer is designed to save energy. The machine will
shut off wash pump, conveyor motors and other auxiliary
control system after the last rack exits the dishwasher. To
restart, slide a rack into the machine or push WASH switch to
ON to change time setting, please contact the local authorized
service office.
Wash Actuator and Rinse Actuator
Wash actuator, which is located at the entrance of the machine,
works only when the timer is on AUTO. When the rack enters
into the machine, wash begins. The rinse actuator is located at
the exit of the machine. When the rack enters rinse section
from the wash tank, the rinse actuator activates, the final rinse
begins.
Wash and Rinse Arms
Wash and rinse arms are removable, convenient for cleaning
and obstructions clearing.
