Quick Guide
Pour water into the bath until it is at least ¾
full or the fluid level reaches the crease in
the tank. To reduce the process preparation
time, fill your bath with water at the
temperature required for your process. The
water you pour in must not exceed 50°C.
Add the required dose of detergent (see
page 11).
Operate the ultrasonics by turning the timer
dial to the required time and pressing the SONICS button (where
applicable).
Operate the heater, if the bath has a heating function, by turning the
heater dial to the required temperature and pressing the HEAT button.
Turn on the ultrasonics for approximately 5-10 minutes to degas the
cleaning liquid. (See page 10 for more details on degassing).
The bath is now ready to use.
At the end of the cycle, remove the basket
from the bath and rinse the items under
clean running water.
The lid can be inverted and the basket
placed on top to catch excess fluid as the
items dry.
Please refer to the following pages in this manual for more detailed
instructions.
Change the cleaning liquid at regular intervals. Your cleaning process will
determine how often to change the liquid – the more soiled your items, the
more often you will need to change the liquid.
SLS recommends changing the cleaning liquid at least on a daily basis.

Technical Information
The need to degas
In order to allow optimum ultrasonic activity, the gases present in ordinary
tap water need to be driven out of the cleaning solution.
The time needed to degas the liquid varies depending on the amount of
gas present in the liquid and the quantity of water in the tank. SLS
recommends a degas period of at least 10 minutes.
During the degas cycle, you will see bubbles of gas forming on the inside of
the bath, and slowly rising to the surface. Degassing is complete when you
can no longer see these bubbles. Another indication of increased “cold-
boiling” at the liquid surface indicates that the liquid is degassed.
Once the liquid is degassed, the bath is ready for use.
The effect of heat
Heating the liquid in the bath
will aid the cleaning process.
Normally a temperature of
between 30 to 65°C is sufficient
to accelerate the process. You
will see from the graph below
that optimum cleaning will be
obtained at 60°C
If you are using your bath to clean medical equipment, it is recommended
to limit the fluid temperature to 45°C. This will avoid “baking” proteins.
Ultrasonic activity itself will heat up the liquid at a rate of approximately
10-15°C per hour if in continuous use.
Cleaning time
Cleaning time will depend on application, type and amount of
contamination. General light contamination should be removed in less than
10 minutes.
An indication of cleanliness is when stains are no longer visible, and
contamination no longer appears in a stream from the item being cleaned.

contamination. SLS recommends a dosage of between 2 and 5% for all
detergents other than Sonozyme.

SLS Lab Pro Analogue Ultrasonic Bath 12 C60 569 01
Maintenance
It is important to keep your bath clean. Not only will contaminated liquid
reduce the performance of the bath, it may also damage it. Change the
cleaning liquid regularly. Your cleaning process will determine how often to
change the liquid – the more soiled your items, the more often you will
need to change the liquid. Change the cleaning liquid at least daily.
The base of the bath generates the ultrasonic activity by vibrating at very
high speeds. If any contaminants are in contact with the bath, they act as
an abrasive, causing wear on the metal surface. In extreme cases, the
bath will develop holes and start to leak.
Portable Appliance Testing (PAT) should be conducted with water in the
bath.
There are no user serviceable parts inside the bath. All service and repair
must be conducted by suitably trained and qualified engineers.
Disposal of this ultrasonic bath
At the end of its useful life, please ensure that you dispose of this product
in accordance with national regulations.
Returning equipment
All equipment being returned for service, repair or other reason MUST BE
FULLY DECONTAMINATED prior to return and include a copy of the
certificate of decontamination.
Failure to do so may result in additional charges, or the equipment being
returned to the user/sender at our discretion.
Ultrasonic baths which have been used in medical/healthcare applications
should be decontaminated/packaged in accordance with MHRA guideline
document DB2003(5) ‘Management of Medical Devices prior to Repair,
Service or Investigation’, this can be found at www.mhra.gov.uk

Compliance with the Control of Noise at Work regulations
The Control of Noise at Work Regulations 2005 (the Noise Regulations[1])
came into force for all industry sectors in Great Britain on 6 April 2006. The
Control of Noise at Work Regulations 2005 replaces the Noise at Work
Regulations 1989.
The aim of the Noise Regulations is to ensure that workers' hearing is
protected from excessive noise at their place of work, which could cause
them to lose their hearing and/or to suffer from tinnitus (permanent
ringing in the ears).
The level at which employers must provide hearing protection and hearing
protection zones is now 85 decibels (daily or weekly average exposure)
and the level at which employers must assess the risk to workers' health
and provide them with information and training is now 80 decibels. There
is also an exposure limit value of 87 decibels, taking account of any
reduction in exposure provided by hearing protection, above which workers
must not be exposed.
To help you calculate your workers’ exposure, we publish the noise
generated by your ultrasonic cleaner on the Certificate of Test. The figure
is that experienced by a worker standing in the operating position.
The full text of the Control of Noise at Work Regulations 2005[2] and the full
text of the Noise at Work Regulations 1989[3] can be viewed online.
Guidance on the 2005 Regulations can be found in the free HSE leaflet
'Noise at Work'(INDG362 (rev 1)[4] and in HSE's priced book 'Controlling
Noise at Work' (L108) (ISBN 0 7176 6164 4) available from HSE Books[5]
or from bookshops.
