Low solution level
- will cause the cleaner to fail. When you remove heavy or bulky loads
from the cleaner, the solution level may drop below the operating level. If so, be sure to
replace lost solution and degas, if necessary, depending on the amount used.
Overload
- do not rest any items on the tank bottom. Weight on the tank bottom dampens
sound energy and will cause damage to the transducer. Instead, use a tray and/or beaker
positioning cover to support all items. Allow at least one inch between the tank bottom and
the beaker or receptacle for adequate cavitation.
Covers
- allow the cleaner to heat up faster, to a higher temperature, and avoid excessive
liquid evaporation.
Temperature
Heater
- the heater may cause some discoloration of the tank wall. This is normal and will
not affect the performance of the unit.
Solution
- the fastest method to heat your cleaner is to fill with warm solution, use heat,
ultrasonics (which also adds heat), and a cover.
Solution activity
- the amount of visible activity is not necessarily related to optimum
cavitation for cleaning.
Degassing
- fresh solutions contain many dissolved gases (usually air), which reduce
effective ultrasonic action. Although solutions will naturally degas over time. Solutions that
have been sitting unused for 24 hours or longer have reabsorbed some gases.
Heat
- increases the chemical activity of cleaning solutions.
Surface tension
- can be reduced by adding solution to the bath. Reduced surface tension
will increase cavitation intensity and enhance cleaning.
Solvents
- never use solvents. Vapors of flammable solutions will collect under the cleaner,
where ignition is possible from electrical components.
Renewal
- replace cleaning solutions often to increase ultrasonic cleaning activity.
Solutions, as with most chemicals, will become depleted over time. Solutions can become
contaminated with suspended soil particles which coat the tank bottom, inhibiting ultrasonic
activity.
