SAFETY & CLEANING

Electrical: This cabinet is supplied with a ready made mains lead conforming to international standards :– Green/yellow = earth Blue = neutral Brown = live A fused plug or distribution board must be used. This apparatus MUST be fully earthed. For a complete electrical disconnection pull out the mains plug.

Cleaning: This is an electrical appliance. The chamber and outside cabinet should only be cleaned with a damp detergent cloth or alcohol wipe only after disconnection from the electric supply. Leave the door open to aid drying before plugging in the electric supply and switching on again.

Spillages: All spillages must be cleaned up immediately – remember to disconnect from the electric supply first. Major spillages in the chamber should be cleaned away and the appliance checked by a competent electrician before being put back into use. Any damage caused by spillages is not covered by the warranty.

This appliance must not be used in the presence of flammable vapours.

The fan is designed to run continuously even with the door open.

If in doubt please call your local distributor. OPERATING INSTRUCTIONS

1 Site the cabinet on an even, level surface. Special static stands are available.

2 Connect to the mains supply and switch on. The on/off switch will illuminate. Wait for the orange heat lamp to come on (this can take a few minutes whilst the controller self actuates).

3 Set the digital controller to the desired operating temperature.

4 The amber heat light will illuminate when there is power applied to the heating element. Once the chamber air temperature has reached the required operating temperature the amber light will periodically switch on and off.

5 To adjust the operating temperature push ‘set’ then use the /\ and \/ buttons to display the desired temperature, then push the ‘set’ button again so that the display shows both ‘set’ (lower displayed number) and ‘actual’ (top displayed number) values.

6 The overheat safety thermostat is factory set to cut power to the heating element if the measured temperature exceeds 500C. It is not user adjustable.

If in doubt please call your local distributor. TROUBLESHOOTING GUIDE

1 Cabinet appears ‘dead’. Check that the power lead is correctly fitted into a working socket and also pushed firmly into the rear connector on the cabinet. Check that the cabinet is switched on using the illuminated green power switch on the front of the cabinet. If you are satisfied that the cabinet is ‘dead’ then call to arrange for an engineer to visit.

2 Temperature is erratic. This is usually caused by over-filling the cabinet.

3 Cabinet is not heating: A) If the amber heat light is on but the cabinet is not heating the problem will probably be either a faulty overheat controller or heating element. Call to arrange for an engineer to visit.

B) If the cabinet is warm at the top but hot at the base it will probably be the fan at fault. Fan failures are usually the result of spillages not being cleaned up properly. You can hear the fan working if you listen close to the cabinet or open the door a little. Call to arrange for an engineer to visit.

4 There is a nasty smell. The usual cause is that a spillage has not been cleaned away properly and that fluids have ingressed to the heating element and the residue has started scorching. Call to arrange for an engineer to visit if the problem persists.

5 Amber light keeps going on and off. This is normal operation and not a fault.

6 Door won’t close properly. The door catch mechanism needs replacing.

If in doubt please call us or your local distributor.

Please remember that all call-outs due to user error or mis-use, even in the warranty period, are fully chargeable.
