Safety instructions
Use of products
The following products are covered by this operating manual:
XUBA1, XUBA3
The products listed above are a series of general purpose ultrasonic cleaning baths
designed for indoor use by a professional user.
Electrical
Connect to a 230VAC fully earthed supply via a 3 pin 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.
Some baths are fitted with a detachable mains lead. These baths have a mains socket
on the rear of the bath fitted with two 20mm fuses. See rating information on page 15.
NEVER FIT A FUSE OF A HIGHER RATING.
Ensure that excess mains cable is stored neatly.
General use
Ensure that the bath is at least ¾ full of 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 the warranty.
Do not place hands or fingers in the bath.
Care should be taken when operating the bath at higher temperatures as external sur-
faces may become hot.
Never use toxic, flammable, acidic, caustic or corrosive solutions in the bath.
Where the bath is fitted with a detachable mains lead disconnect the bath from the
mains supply before emptying. When emptying baths with no waste outlet, tip the bath
AWAY from the electrical connector and lead.

Fill Line
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 (see page 10).
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 func-
tion, by turning the heater dial to the required tem-
perature and pressing the HEAT button.
Turn on the ultrasonics for approximately 5-10 min-
utes to degas the cleaning liquid. (See page 8 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.
Grant 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. 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 in-

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 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

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 fluid in the tank at a faster rate, it is rec-
ommended to run the ultrasonics as well as turn on the heating.
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.

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.

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.
