Electrical Installation

THIS EQUIPMENT MUST BE EARTHED

Before connection please ensure that the line supply corresponds to that shown on the rating plate.

All models are supplied with two mains leads fitted with IEC plugs for connection to the instrument.
One has a U.K. 3 pin plug and the other has a 2 pin “Schuko” plug for connection to the mains. Choose the lead appropriate for your electrical installation and discard the other. Should neither lead be suitable, take the lead with the U.K. plug and replace the plug with a suitable alternative. This involves cutting off the moulded plug, preparing the cable and connecting to the re-wireable plug in accordance with its instructions.

THIS OPERATION SHOULD ONLY BE UNDERTAKEN BY A QUALIFIED ELECTRICIAN

NOTE : Refer to the equipment’s rating plate to ensure that the plug and fusing are suitable for the voltage and wattage stated

CAUTION – Fuse fitted in both live and neutral lines.

Fuses
230V: 2 x 10A fuses. For all other voltages always replace with an equivalent fuse type and rating as those being removed, alternatively see rating plate for fuse type and rating.

The wires in the mains cable are coloured as follows:
BROWN – LIVE
BLUE – NEUTRAL
GREEN/YELLOW – EARTH

The instruments are fitted with an IEC socket at the rear of the instrument for connection of the mains lead. The appropriate mains lead should be connected BEFORE connection to the mains supply.
When wishing to isolate the bath from the mains supply, disconnect the cable from the IEC socket.
Should the mains lead need replacement, a cable of 1mm2 of harmonised code H05W-F connected to an IEC320 plug should be used.

IF IN DOUBT CONSULT A QUALIFIED ELECTRICIAN

Safety Advice Before Use

USE CAUTION WHEN REMOVING VESSELS FROM THE BATH AS PARTS MAY BE HOT.

BE AWARE THAT STEAM MAY BE RELEASED WHEN REMOVING THE LID

• The unit should be carried with both hands, with fingers under each side.
• Never move or carry the unit when filled with water, while it is in use or connected to the mains supply.
• Use only water and no other liquid in the bath.
• Do not lean over the bath when removing the lid as steam may be released. Open the lid slowly to allow steam to disperse safely.
• Allow water to cool before draining.

General Description

The SWB series digital water baths are ideal for heating vessels and maintaining samples at a constant temperature. They are available in 6L, 15L and 24L options to accommodate different vessels of different sizes. They have a one-piece stainless steel construction for ease of maintenance and cleaning.
In addition to this, a drain tap aids removal of the bath water. For safety, all baths have a water level sensor to prevent the bath running dry. Temperature is maintained by a PRT temperature sensor and there is an over- temperature cut out for added safety. To avoid evaporation and improve temperature control, clear polycarbonate covers are included with the baths.

Operation

Recommended Bath Water

The inner containers of the Cole-Parmer water baths are manufactured from grade 304 stainless steel, a material which is extremely hardwearing, easy to clean and with excellent corrosion resistance.

It is important to remember that although stainless steel has a higher resistance to oxidation than ordinary steel in various environmental conditions, it is not rust and corrosion proof.
Care must be taken when using the baths not to use or introduce chemicals which may cause damage to the surface of the bath. Regular cleaning and maintenance will prolong the life of the bath and enable continued use for many years. For the Cole-Parmer baths we recommend water, preferably distilled or deionised, with neutral pH.
Ultra pure deionised or RO water with a resistivity >1Mohm should not be used, as this can leach the iron from the stainless steel and lead to corrosion. If necessary, add a little tap water to the pure water in the bath. Hard tap water should also be avoided as this can cause build up of scale inside the bath and on the heating elements. Other salts in tap water such as chlorides and sodium ions can also lead to pitting and corrosion.

Setting up
Position the apparatus on a firm level surface and insert the mains lead into the socket on the rear of the unit. Ensure the isolation switch is easily accessible during use.
Attach a suitable length of hose to the drain tap at the rear of the bath to allow for draining off the water after use. Ensure the drain tap is accessible to prevent spillage when the bath is full.
Note : To ensure correct operation, prior to use you should clean the level sensor with a mild solvent, such as Isopropyl alcohol.

Connect to the mains electricity supply.
Fill with water to a level above the low water level sensor inside the bath. It is advisable to use distilled or deionised water with neutral pH to avoid scale formation. Ultra pure deionised or RO water with a resistivity >1Mohm should not be used, as this can leach the iron from the stainless steel and lead to corrosion.
Periodically top up with water to maintain the desired level.

Temperature setting
When connected to the mains electricity supply the LED display will illuminate and show the word OFF.
Switch the unit on by pressing the “Power On/Off” knob. The display will momentarily show the set temperature followed by the actual water temperature in degrees Celsius.
Press and hold the “Press to set” button. The display will show the set temperature. The set temperature may be adjusted by turning the “Temperature adjustment” knob whilst continuing to hold in the “Press to set” button. When the desired setting is displayed release the “Press to set” button. The display will revert to show the actual water temperature and the bath will begin to heat.
The set temperature can be observed at any time by pressing the “Press to set” button.
Turning the adjustment knob without pressing the “Press to set” button will have no effect on the temperature setting.

Hot indicator
When the bath temperature rises above 50ºC, the hot indicator will begin to flash. This will continue even when the power is turned off at the “Power On/Off” knob until the water temperature falls below 50ºC.
When the power is off, the LED display will also glow with the word “Hot” until the water temperature is below 50ºC.

CAUTION – Use protective gloves to remove hot vessels.

Low water level sensor
The low water level sensor is designed to provide a warning when the water level has become too low in order to protect the bath from overheating. When the water level drops below the sensor, the LED display will flash “H2O” and “ERR” to indicate that the water level is too low and the heater will switch off.
The heater may be re-started by filling the bath above the level of the sensor.

Drain tap
The drain tap allows for easy removal of the bath water for maintenance and cleaning. Ensure the bath is turned off and the water is cool before draining.
Direct the hose from the drain trap to a sink or waste collection vessel. Open the tap valve and allow the water to flow out. Close the tap before re- filling.

Maintenance & Servicing

WARNING : Ensure the unit is disconnected from the mains electricity supply before attempting maintenance or servicing.

Maintenance
It is recommended that the bath is drained, cleaned and re-filled on a weekly basis to avoid build up of salts and contamination. For baths that are used for biological applications and heated to physiological temperatures, regular heating to >60ºC for 30 minutes can be used to thermally disinfect the bath before cleaning. Do not use bleach (sodium hypochlorite) or other chlorine based solutions as a disinfectant.

Cleaning
In general baths should be cleaned with a mild household or laboratory detergent using a sponge or soft cloth. Scouring powders, steel wool or other abrasive pads should not be used. Scale build up can be removed using a mild household descaler suitable for stainless steel; follow the manufacturer’s instructions for correct use. Rinse thoroughly after cleaning and dry the bath.
For cleaning of the low water level sensor, Freon and alcohol based solvents are recommended. DO NOT use chlorinated solvents such as trichloroethane as these are likely to attack the sensor material.
Periodically clean the outside of the unit using a damp cloth and mild detergent solution. Do not use harsh or abrasive cleaning agents.
In some cases small spots may be visible in the baths which resemble rust spots. In most cases these will be small ferrous particles on the surface of the bath which have oxidised causing the appearance of rust.
These can usually be cleaned away using a standard stainless steel cleaner and plastic scourer.

Servicing
Any repairs or replacement of parts MUST be undertaken by suitably qualified personnel.
