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.

Periodic testing and validation
It is a requirement of decontamination guidelines that the Hygea 2850VM ultrasonic
bath is periodically tested and validated to ensure optimum performance as outlined in
HTM01-05 and HTM2030.
The following pages outline Ultrawave (the manufacturer’s) guidelines for the periodic
testing of the Hygea 2850VM ultrasonic bath. The frequency and nature of these tests
are recommended as the minimum protocols that should be followed in order to ensure
optimum performance of the bath and to adhere to applicable regulations and
guidelines. In some cases, more frequent testing schedules may be stipulated.
1. Weekly tests (carried out by the operator)
Cleaning efficacy test using the Brownes STF Load Check Indicator strips and holders
(available from Ultrawave).
2. Monthly tests (carried out by the operator)
Ultrasonic activity test using the Hygea Ultrasonic Energy Meter (available from
Ultrawave). If there is no access to the Energy Meter, this test should be replaced by
the aluminium foil ablation test.
3. Quarterly tests (carried out by the operator/Estates department)
Ultrasonic activity test using the aluminium foil ablation test (available from Ultrawave).
4. Annual Validation Tests (carried out by Ultrawave approved engineer)
A combination of tests ensuring correct and accurate operation of all components of the
Hygea 2850VM (including automatic control tests, cleaning efficacy, ultrasonic activity
tests, electrical safety test, diagnostic test etc.)
Note: Each test should also include the test(s) itemised above as the less frequent tests.
Eg. When conducting the quarterly test, the weekly and monthly tests should also be
carried out as part of the same routine.
Contact the Ultrawave Service department [phone] or
[e-mail] to discuss Service Contract and periodic testing options
packages.
All components needed to carry out periodic testing, including a complete Validation
Kit, can be purchased from Ultrawave.
