TIPS AND TRICKS
The cleaning solution used in ultrasonic cleaning is a very important factor in the process to take time in selecting the right cleaning medium for all tasks. Consideration must be given to the base material of the item to avoid discolouration or corrosion. For further information see cleaning chemicals or contact unisonics representatives.
A recommendation on mixing ratios of chemicals supplied can be varied according to the degree of contamination. Good judgement and common sense should prevail.
Always urge on the edge of caution when immersing untried items to avoid irreversible damage. A presoak or rinse of heavily contaminated instruments may be required to reduce cleaning time.
When commencing the operation of the ultrasonic cleaner it is critical to allow a few minutes for fresh fluids to degas. This improves the efficiency of the cleaning allowing shorter immersion time.
The liquid level should never drop below 50mm from the ultrasonic tank bottom as the increase in fluid temperature as a result of a low operating depth can cause damage to the transducer bonding. Heated ultrasonic cleaners should always include a thermostat control with immersion type heaters avoided at all costs. A gradual increase in temperature as a result of the ultrasonics is normal in all cases. Heavy or sharp objects should never be allowed to rest on the bottom or sides of the chamber but retained in a basket or racking system. This item supplied as standard with all unisonics ultrasonic cleaners.
The transducer and ultrasonic tank are part of an oscillating system which needs to be free of any contact to perform at maximum working levels. Hot fluids should never be poured directly onto the tank bottom as untold damage to the transducer bonding medium will render the ultrasonic cleaner inefficient and unreliable. Conversely when the ultrasonic cleaner has been operational for long periods a waiting time is required when introducing new fluid. This again is to avoid a hot/cold scenario between dissimilar materials.
When locating the ultrasonic cleaner always keep the unit at a safe distance from sinks or water outlets to eliminate electrical breakdown. Always drain the basket or rack fully of fluid before extracting from the ultrasonic cleaning chamber.
Take care when refilling the ultrasonic chamber as not to allow excess spillage or splashing onto power mains outlets or timer controls.
Unwanted residue left after the cleaning process should always be rinsed or wiped clean from the internal ultrasonic tank to avoid corrosion on the tank surface. The operator should always be aware that it only takes a small amount of moisture contamination on the power connections to cause electrical breakdown.
