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 unit is supplied with a removeable mains lead rated at 5A. Do not use a power

lead rated less than 5A.

The removeable mains lead is the disconnect device and should remain accessible

while the unit is in use.

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.

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 surfaces 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.

Read the whole of these instructions. Safety may be impaired if they are not followed.

Contact to Grant or its agent for advice on cleaning techniques and detergents.

Grant will not be responsible for damage or injury caused by incorrect use of the

equipment.

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

function, by turning the heater dial to the required

temperature and pressing the HEAT button.

Turn on the ultrasonics for approximately 5-10

minutes 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

increase in the appearance of ‘cold boiling’ at the liquid surface.

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

fluid 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 fluid in the tank at a faster rate, it is

recommended 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.

Detergents are a vital component in the ultrasonic process, aiding 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.

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 ultrasonic bath are available from Grant. Contact us for

more information (+44 (0) 1763 260811).

Operating Manual

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.

To help you calculate your workers’ exposure, Grant publish the noise generated by

your ultrasonic cleaner on the Certificate of Test. The figure is that experienced by a

worker standing in the operating position.

The full text of the Control of Noise at Work Regulations 2005[2] and the full text of the

Noise at Work Regulations 1989[3] can be viewed online.

Guidance on the 2005 Regulations can be found in the free HSE leaflet 'Noise at

Work'(INDG362 (rev 1)[4] and in HSE's priced book 'Controlling Noise at Work' (L108)

(ISBN 0 7176 6164 4) available from HSE Books[5] or from bookshops.
