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 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.

Installation

The following parts and accessories are included with the Grant analogue ultrasonic baths:

• 1 x basket
• 1 x lid
• 1 x Grant M2 detergent sample

How to install
Locate the bath close to a drain or sink to allow easy drainage of the tank.
Connect the mains lead into a suitable mains socket.
Ensure that the mains plug and the switch are easily accessible.
Fill the bath with water and the correct dose of detergent. The bath is now ready to use.

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.

REMEMBER

• Always keep the bath full of liquid when in operation.
• Do not put hot water above 50°C into the bath.
• Always use the basket to support items in the bath.
• Never expose hands, fingers or other body parts to cleaning solutions.
• Never use toxic, flammable, acidic, caustic or corrosive solutions.
• Never breathe the fumes from strong solutions.
• Rinse the items in clean water once the cycle is complete.

Subjecting the bath to improper treatment or misuse will invalidate the warranty.

XUBA1 Control panel instructions

To switch on the ultrasonics:
Turn the TIME dial to the desired time, and then press the SONICS button.
The SONICS button and the SONICS light will glow. Ultrasonic activity will then commence in the liquid inside the tank and the TIME dial will be heard ticking.
At the end of the timed period, the TIME will click off, the SONICS light will go out, and the ultrasonic activity in the liquid will stop.
To stop the ultrasonic activity at any time, press the SONICS button while in operation.

XUBA3 Control panel instructions

To switch on the ultrasonics:
Turn the TIME dial to the desired time, and the press the SONICS button.
The SONICS button and the SONICS light will glow. Ultrasonic activity will then commence in the liquid inside the tank and the Timer dial will be heard ticking.
At the end of the timed period, the TIME will click off, the SONICS light will go out, and the ultrasonic activity in the liquid will stop.
To stop the ultrasonic activity at any time, press the SONICS button while in operation.

To operate the heater:
Turn the HEATER dial to the desired temperature, and press the HEAT button.
The HEAT button and the HEAT light will glow, and the liquid will start to heat up.
When the set temperature is reached, the HEAT light will go out.
To stop the heater at any time, press the HEAT button while in operation (ie. when the HEAT light is already on).
NOTE: Ultrasonic activity itself will heat the liquid. This means that the liquid temperature may rise above the level indicated on the temperature dial.
The temperature dial only controls the heater cut-out temperature.
If in doubt, check the actual temperature with a thermometer.

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.

Grant M2 is biodegradeable

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 regularlyYour 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 cleaningliquid at least daily.
The base of the bath generates the ultrasonic activity by vibrating at very high speedsIf any contaminants are in contact with the bath, they act as an abrasive, causing weaon the metal surface. In extreme cases, the bath will develop holes and start to leakportable appliance testing should be conducted with water in the bath.
There are no user serviceable parts inside. All service and repair should be referred toqualified 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.
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.
