Safety instructions & general use
Safety Instructions
The SLS Lab Pro digital ultrasonic baths are intended to be used to clean laboratory
equipment.
The SLS Lab Pro digital ultrasonic baths are designed for indoor use by a professional
user.
Electrical
Connect to a 230 VAC fully earthed supply via a 3pin plug.
It can be dangerous to operate an ultrasonic bath without an earth connected.
The mains plug is fitted with a 5A fuse. NEVER FIT A FUSE OF A HIGHER RATING.
The detachable mains lead is rated at 250V 6A. NEVER FIT A LEAD WITH A
LOWER RATING.
The detachable mains lead is the disconnect device and should remain accessible
while the machine is in use.
Ensure that excess mains cable is stored neatly.
General use
Ensure that the bath contains liquid before you switch it on.
Always use a basket to support items to be cleaned.
Not doing so may damage the bath and invalidate your warranty.
Do not place hands or fingers in the bath.
Care should be taken when operating the bath at higher temperatures as external
surfaces may become hot.
Never use toxic, flammable, acidic, caustic, or corrosive solutions in the bath.
Do not move the bath when it contains water.
Before cleaning, drain the bath. Clean by wiping with a clean non-abrasive cloth.
The user should familiarise themselves with this Operator Instruction manual before
operating the equipment and should apply to SLS for advice on cleaning techniques or
detergents. We will not be responsible for damage or injury caused by incorrect use of
the equipment.

Quick guide
Pour cold water into the bath so that it
submerses the level sensor (Do not overfill).
Add the required dose of detergent (see page
24).
To save the cycle data to the memory card,
ensure that the memory card is installed in the
port prior to turning the machine on (see page
22).
Switch on the machine via the switch at the
rear of the unit, just above the electrical mains
lead.
Press the “START” key to accept the
programmed cleaning cycle settings and start
the cleaning cycle.
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 liquid as the items dry.
REMEMBER
- Always ensure the liquid is above the level sensor when in operation.
- Do not put hot water above 50°C into the bath.
- Always use the basket.
- Never expose hands to cleaning solutions.
- Never use toxic, flammable, acidic, caustic, or corrosive solutions.
- Never breathe the fumes from strong solutions.
- Rinse the items in clean water once the cycle is complete.
Subjecting the bath to improper treatment or misuse will invalidate the warranty.
Liquid level sensor

SLS Lab Pro Digital Ultrasonic Baths 6 C6056801
Operator instructions
When the power is turned on and the bath is full of liquid, the following screens will
display alternately.
When the water temperature is at or above the temperature set, the message “Temp
OK” will display.
The actual temperature in the bath will vary and will be different to the value shown in
the screen above.
To immediately start the cycle using the already set cleaning parameters, press the 8
key.
Your SLS Lab Pro ultrasonic bath remembers the set parameters from the previous
cycle. If the operator wants to run the same cleaning cycle, it is therefore not
necessary to run through the menu each time.

When the power is turned on and the liquid level is too low, the following screen will
display.
The level sensor can be disabled for specialist cleaning applications where deionised
(DI) water is used (see page 19).
When the bath is filled with liquid to the correct level, you will be given the option to
degas. (The need for degassing is explained on page 25).
You will need to degas the liquid to ensure good cleaning efficacy.
By choosing YES, your SLS Lab Pro ultrasonic bath will run an automatic de-gas
cycle. The following screen will display.
The degassing process is to remove all bubbles from the water as these impede the
cleaning performance. Once all the bubbles have come to the surface, complete the
degassing cycle by pressing the 8 key.
Note: If the machine detects low liquid level for more than 5 seconds, it is assumed
that the bath has been filled with fresh water, and you will be given the option of
running another degas cycle.

Operator menu
Several of the cleaning parameters can be altered.
To access the options menu and scroll through the various changeable parameters,
press the MENU key, when the following screen is displayed.
To scroll through the menu, press the MENU key. To exit the MENU at any time,
press the 8 key.
Your SLS Lab Pro ultrasonic bath remembers the set parameters from the previous
cycle. If the operator wants to run the same cleaning cycle, it is therefore not
necessary to run through the menu each time.
