Screen 5: Low power
In its factory pre-set mode, the Grant digital ultrasonic bath will maintain the set liquid
temperature. This means that it is consuming power when sitting idle (i.e. when the
sonics are not running).
The Grant digital ultrasonic bath can be set to save power when not in use.
Setting Low Power to ON means that after five minutes of inactivity, the Grant digital
ultrasonic bath will enter its SLEEP mode – the screen illumination will power down,
and the internal water heater will not operate.
The Grant digital ultrasonic bath uses less than 10 Watts of power whilst in SLEEP
mode.
By setting Low Power to OFF, the Grant digital ultrasonic bath screen will maintain the
set liquid temperature; i.e. when the liquid temperature falls below the specified setting,

Screen 6: Liquid level sensor
The Grant digital ultrasonic bath is fitted with a liquid level sensor to ensure it is not
under-filled prior to or during the cycle. This ensures that the optimum cleaning
process can occur and potential damage to the tank is minimised.
The level sensor is a resistive device, so will not detect liquids with very low
conductivity such as pure deionised (DI) water.
The level sensor can be disabled for specialist applications where deionised (DI)
water is used.
Use the ON and OFF keys to set the Low Level function. When the desired option is
selected, use the MENU key to move to the next screen.

WARNING
Setting the liquid level sensor to OFF means that the Grant digital ultrasonic bath will
operate as if the bath were full of liquid.
This means that without water, the heaters will continue to operate and the surface
inside the bath will become extremely hot. It is therefore the operator’s responsibility
to ensure that the tank is filled with sufficient water when the liquid level sensor is
disabled.
If the Grant digital ultrasonic bath operates with insufficient liquid, the heaters will be
disabled as a safety feature and the following screens will be displayed:
To continue using the Grant digital ultrasonic bath, refill with liquid up to the liquid level
sensor and switch the unit off and on again.
If the bath is run dry this will invalidate the warranty on the Grant digital
ultrasonic bath.
A warning label is included in the literature pack that may be applied to the
unit if deemed necessary following a risk assessment
(see ISO 13732-1:2006).

Using the Memory Card
The Grant digital ultrasonic bath is fitted with a memory card (MC) slot which allows
digital validation of every cleaning cycle.
Simply insert an MC card into the slot located at the front of the Grant digital ultrasonic
bath to ensure that information on each cycle is saved to the MC card.
The Grant digital ultrasonic bath is supplied with an MC card which allows easy
transfer of the cycle information from the ultrasonic bath to a PC.
In order to record the cycle parameters, always ensure the MC card is inserted into
the Grant digital ultrasonic bath prior to turning the power on.
By recording to an MC card and transferring to a PC, a permanent electronic record of
the cleaning cycle parameters can be saved.
The information is saved as a CSV file. This is automatically saved as cycles.csv on
the MC card and will open in any text editing software.
The information saved includes cycle number, cycle time, cycle temperature and
validation of the ultrasonic activity achieved during the cycle.

Detergents are a vital component in the ultrasonic process, aiding in the removal and
loosening of debris from the surfaces of items placed in the tank while also
intensifying the power of the ultrasonic activity.
Grant offers a specially formulated ultrasonic detergent for use in many applications.
Grant M2 is a general purpose detergent for all plastics, glass and metals (expect
aluminium and other soft metals) which is also suitable for use on medical instruments.
Dosing Matrix (ml of detergent per tank)
Grant recommends a dosage of between 2 and 5% for all detergents.
Directions for use: Add 25-50ml of M2 per litre of water in the ultrasonic bath.
Warning: Grant M2 may cause etching to aluminium and other soft metals.
Shelf life: 6 months when stored in a cool, dark environment.
Precautions for use: In case of contact with eyes, rinse immediately with plenty of
water and seek medical advice. If swallowed, seek medical advice immediately and
show this label. Keep out of reach of children.
Refer to Safety Data Sheets available from Grant
Grant M2 is biodegradable.

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. Grant 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 that the liquid in the bath has degassed is an increase in the
appearance of ‘cold boiling’ at the liquid surface.
Once the liquid is degassed, the bath is immediately useable and will run the cleaning
cycle.
The effect of heat
Heating the liquid in the bath
will aid the cleaning process.
Normally a temperature of
between 30 to 60°C is sufficient
to accelerate the process. You
will see from the graph 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 liquid
temperature to 35°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. In order to heat the liquid in the tank at a faster rate, it is
recommended to run the ultrasonics as well as turn on the heating.
Cleaning time
The Grant digital ultrasonic bath is factory preset with a cleaning time of 15 minutes.
Some components may take longer or shorter to clean effectively depending on the
contaminants and the level of contamination.

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 should be conducted with water in the bath.
There are no user serviceable parts inside. All service and repair should be referred to
qualified Grant engineers only
Service contracts for your Grant digital ultrasonic bath are available from Grant.
Returning equipment to Grant
All equipment being returned to Grant for service, repair or other reason MUST BE
FULLY DECONTAMINATED prior to return and include a certificate of
decontamination.
Failure to do so may result in additional charges or the equipment being returned to
the user/sender at Grant’s 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.
This policy is designed to protect the health and safety of Grant employees, reducing
the risk of potential injury or infection.
More information on decontamination guidelines, as well as copies of decontamination
certificates can be found at www.grantinstruments.com
