Safety instructions
Connect to a 220-240 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.
Ensure that excess mains cable is stored neatly.
When the temperature is set to 54°C or above, the Hygea 2850VM will become hot
and care should be taken when touching the case.
A risk assessment should be conducted if the temperature is set to 54°C or above –
see BS EN ISO 13732-1:2008 for full details
General use
Ensure that the bath contains liquid before you switch it on.
Always fill with cold water. This will ensure that the Hygea 2850VM always runs its
automatic de-gas cycle (see pg 27 for the importance of degassing).
Always use a basket or instrument cassette and basket carrier to support items to be
cleaned.
Not doing so may damage the bath and invalidate your warranty.
Do not place fingers or other parts of the body in the bath.
For best cleaning results use a detergent, at a suitable dose, recommended for use in
ultrasonic cleaning baths. Never use toxic, flammable, acidic, caustic or corrosive
solutions in the bath.
Refer to the Hygea 2850VM Operator Instructions manual for full guidance on the
correct use of the bath.
The user should familiarise themselves with this Operator Instructions manual before
operating the equipment and should apply to Ultrawave or its agent for advice on
cleaning techniques or detergents.
Ultrawave 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 reaches the minimum tank fill line (but does not
go over the maximum fill line).
Add the required dose of detergent. Ultrawave recommend Sonozyme detergent
sachets. Ultraclean M2 is also suitable.
Switch on the machine via the switch at the rear of the unit, on the left hand side,
above the electrical mains lead.
If the water is below the minimum temperature, the Hygea 2850VM will automatically
start degassing and heating the liquid.
Once the water is heated to the minimum operating temperature, the Hygea 2850VM
is ready to use, although an extra degas cycle may be required.
Press the “ENTER” key to accept the cleaning cycle settings.
Select your operator identification.
Press the “ENTER” key to start the cleaning cycle.
At the end of the cleaning cycle, remove the basket holder from the Hygea 2850VM,
allow it to drain over the bath, then rinse the instruments under clean running water.
REMEMBER
-Always keep the bath full of liquid when in operation.
-Do not put hot water into the bath.
-Always use the baskets or instrument cassettes and holder.
-Never expose hands to cleaning solutions.
-Never use toxic, flammable, acidic, caustic or corrosive solutions.
-Never breathe the fumes from strong solutions.
-Rinse the instruments in clean water once the cycle is complete.
IMPORTANT: Once the cleaning cycle has finished, remove the cleaned items and rinse
them in clean running water.
Subjecting the bath to improper treatment or misuse will invalidate the warranty.
