Optimum Condition for the best results
Cleaning Solutions
Overload :
Do not rest any items on the bath bottom. Weight on the bath bottom dampens
sound energy and will cause damage to the transducer.
(Use a tray and / or beaker positioning cover.)
Liquid Level :
Fill the cleaner to the operating line using warm water.
Low Solution Level :
When you remove heavy or bulky loads from the cleaner, the solution level
may drop below the operating line. (It may cause the heater to fail)
Flammable Solution :
Never use solvents. Vapors of flammable solutions will collect under the
cleaner, where ignition is possible from electrical components.
Temperature :
Approximate stabilization temperatures with ultrasonic and heat running
continuously : 50℃
Rinsing :
Rinse away chemicals which adhere to items after cleaning. A highly effective method
of rinsing is using a clean water bath in your cleaner.
Cleaning :
Check the bath for contamination whenever you change solution. If necessary,
remove contaminants with a nonabrasive cloth and water.
Cover :
Allow the cleaner to heat up faster, to a high temperature, and avoid excessive liquid
evaporation. However, obstructing the cover vents will cause the cleaner to overheat.
Load Size :
It is faster and more efficient to run several small loads rather than a few big loads.
Corrosive Solution :
Never use corrosive solutions such as strong acids or powerful caustics
directly in the bath.
Heater :
The heater may cause some discoloration of the bath wall. This is normal and will not
affect the performance of the unit.
Hwashin cleaner was designed to operate only with the water-based solutions and non-
flammable solutions. Water-based solutions fall into two categories - acidic and alkaline. They
include detergents, soaps and industrial cleaners designed to remove specific soils
Caution
Do not use alcohol, gasoline, bleach, mineral acids, solutions with a flash point,
semi-aqueous or combustible liquids in a bath.
Only use non-flammable solutions and water-based solutions.
