Basic Do’s and Don'ts and general safety advice with our Ultrasonic CleanersFebruary 2009

The following is a list of various Do's and Don't when using our ultrasonic cleaning baths. This list is NOT exhaustive.

DO use the correct fluid for your application
DO NOT use water alone in the tank when operating the unit as a wetting agent is required for correct transference of ultrasonic energy
DO NOT operate the unit without fluid in the tank filled to the correct level.
DO keep the tank free from large amounts of sediment.
DO NOT drop the unit or experience it to shock or impact.
DO NOT immerse the unit in water or any other liquid.
DO NOT use acid, bleach or any corrosive substance in the stainless steel tank, as they may attack the metal.
DO NOT use any highly flammable substances in the tank
DO NOT place your hands in the fluid while the unit is operating
When using any cleaning fluid please read the directions before use. COSHH data sheets are available for all Walker Electronics Limited fluids here
DO NOT pour very hot or boiling water into the tank as this could cause damage to the transducer
DO keep the lid on during use and at all other times when feasible. This will prevent splashes and reduce evaporation of the fluid
DO NOT drop any item into the tank as this may cause damage to the transducer. Always place the item/s gently into the tank and use the basket whenever possible

DO disconnect the mains plug or isolate the supply before: Emptying fluid from the tank, filling the tank with fluid, moving the unit or removing the base screws (NO USER SERVICEABLE PARTS ARE CONTAINED IN THE UNIT.)
DO keep the front panel dry. NEVER allow fluid to run down the unit case or around the cable inlet area
DO NOT operate any switches when your hands are wet

DO NOT use any glass or other containers in place of the recognised beaker. The unit should be operated in an environment as follows: Temperature: 5°C to 40°C – Humidity: 10% to 80% (Non-condensing)
After long periods of operation the top of the tank and fluid may get warm. This is quite normal.
No maintenance is required. To clean the case and tank wipe with a lightly oiled cloth
DO NOT move the unit whilst in use or connected to the mains supply in order to avoid spillage or overflow
