release of toxic or ammable gases) or that these have been addressed. When heating
substances where liberation of gases occurs, suitable extraction should be used.
11. Use only liquids specied within this Instruction Manual within their specied
temperature range.
12. Drain all liquid before moving the water bath.

3.2 Maintenance
Please ensure that the washing agent and sanitising agent are BSI accredited and approved
by the H&S department for use on laboratory equipment and stainless steel within your
laboratory.
ATTENTION: Disconnect the Bath from the Power Supply Prior to Cleaning
Basic Cleaning Procedure:
The stainless-steel crevice free tank should provide years of valuable service and is resistant
to chloride containing solutions, but it is important to avoid high concentrations of halogens-
particularly chloride. Halogen deposits may show as rust which can be cleaned off with nitric
acid (10%) on a cloth. WEAR PROTECTIVE EQUIPMENT!
The water bath should be emptied at the end of each day, then for interior surfaces:
• WASH • RINSE • DRY •
For algae and slime control in water baths, please use Water Bath Conditioner AR.
Occasionally small spots may occur in the bath which resemble rust. These are usually small
ferrous particles which have oxidised. Using a stainless-steel cleanser such as Bar Keepers
Friend®will remove these marks as well as mineral deposits.
Exterior Anti-Bacterial Painted Surfaces:
The water bath should be cleaned at regular intervals by wiping external surfaces with a
cloth or sponge soaked in warm water with a mild detergent.
ATTENTION: Do Not Use Strong Solvents or Solutions Containing Chlorinated Hydrocarbons,
Esters, Ketones or Abrasive Cleaners as this may Damage the Built-In Antibacterial Properties.
4. Installation & Operation
4.1 Installation
The water bath must be placed on a smooth, level, and sturdy work surface, preferably near a
drain for emptying. Use in a ventilated room. Suitable for use in ambient temperatures 5°C to
40°C with a maximum humidity 80% (temperature 31°C) decreasing to 50% (temperature 40°C).
DO NOT block or restrict ventilation slots. DO NOT place directly next to hot heat surfaces.
ENSURE that there is sucient space around the product to allow it to provide optimum
temperature control.
