2. System status LED, comprising of 2 zones. a. Green - system normal b. Red - system leakage in the pipework system Check for disconnected pipework or any adaptors or adaptor plugs missing from the pipework. Note: 3 missing adaptors is equivalent to a disconnected pipe. 3. Illuminated on/off button
Empty filter compartment collection tray 1. Remove the side panel. 2. Lift and slide out the filter tray 3. Place the tray in a suitable polythene bag and empty. 4. Refit 1 and 2.

Bench extractor kit Kit contents: (1) 1 x powder coated base(90 x 90mm) (2) 1 x plastic ON/OFF tap (3) 1 x stainless steel flexible hose (4) 1 x stainless steel nozzle (5) 1 x nut assembly (6) 1 x 1M x 12mm grey flexible hose (7) 1 x pipe adaptor
Renew the pre-filter 1. Remove the side panel. 2. Slide out the filter shelf. 3. Renew the pre-filter and place used filter in a suitable polythene bag for disposal. 4. Refit 1 and 2. Note: If after carrying out steps 1-4 the LED reading remains red, renew the main filter. Before fitting a replacement main filter A certain amount of dust is quite normal at the bottom of the main filter packing box. 1. Hold the filter in a vertical position (airflow arrow pointing up) and shake from side to side. This will ensure that the chemical is level at the bottom of the filter. 2. Place the filter in position in the machine with the test label facing out, arrow pointing up. Lock the filter against the bonded seal by sliding fully back and securing with two locking clamps (located on the side of the filter cradle).
Renew the main filter 1. Remove the side panel. 2. Remove the one piece main filter. (i) Raise the filter latches located on either side of the filter cradle. (ii) Ensure that the filter drops down (3mm min) onto the slide rails and slide out. 3. Renew filter and place used filter in a suitable polythene bag for disposal. 4. Refit 1 and 2. Note: If the LED still reads red refer to the fault finding section. Note: The pre-filter should be changed at regular intervals. This will extend the life of the main filter if it is not allowed to become completely clogged. The main filter should be changed after 9 months irrespective of the LED reading due to chemical saturation.
Filter disposal instructions Note: The filters contain aliminimum oxide impregnated with potassium permanganate and activated charcoal; in addition to this will be the substance which has been filtered. Most European countries will accept the filters as normal harmless domestic refuse. If you are in any doubt, consult your local authority.
System leak light The RS range of Tip Extraction fume purification systems incorporates a seperate sensing circuit which detects a loss of pressure in the system pipework.
A pressure sensitive switch activates the warning system via a sensing line which is connected into a quick release coupling located on the rear of the machine. WARNING! ONLY FULLY AUTHORISED PERSONNEL SHOULD ATTEMPT THESE ADJUSTMENTS.
Setting the system leak light (machine on) a. Complete installation and connect a flow meter to the extraction point farthest away from the machine. b. Remove the pressure regulator valve stem. c. Check that the system leak light has illuminated (red). d. If the system light does not illuminate, connect a 2Ó wg - 10Ó wg vacuum gauge to the leak light pressure switch-sensing line and set system manifold pressure to 2Ó wg by sliding a flat piece of metal or card to restrict the pessure regulator valve. e. Remove sensing line from pressure switch and reconnect to the pressure switch - set switch to illuminate the red system leak light. Note: The light should be balanced so that it comes on fractionally below the green Ôsystem normalÕ light. The system ÔleakÕ light is now set.
Setting the Ôbar graphÕ a. With pressure regulator valve still removed, slide a flat piece of metal across the inlet of the pressure regulator valve to restrict the incoming air. Monitor the flow meter until a flow rate of 14 litres per minute is achieved. b. Using a suitable small screwdriver, turn the Ôbar graphÕ potentiometer (located on the circuit board) until the Ôbar graphÕ lights are flickering between strong Ôfirst redÕ and dim Ôsecond redÕ. The Ôbar graphÕ is now set.
Setting the pressure regulator valve The loss of pressure can be caused by: 1. Disconnected pipework. 2. Operators removing adaptors and adaptor plugs.
a. Refit the pressure regulator valve and adjust until the flow meter reads 28 litres per minute. b. Refit the pressure regulator valve retaining lock nut and tighten.
When the pressure drops to a predetermined level the operator is alerted by an illuminating RED WARNING LIGHT on the instrument panel marked ÔSYSTEM FAILÕ.
