To remove any accumulation of dust or fluff, the soft brush attachment of a vacuum cleaner should occasionally be used.
Sump
1. Press Switch 'A' to the 'OFF' (0) position (Fig 27)
2. Gently lift off the fuel bed and place it aside.
3. Disconnect the 'fill cap' by turning it clockwise until it clicks out of the locked position (Fig 29). Lift it out and rotate
the pipe and connections so that the fill cap is placed out of the way of the sump.
4. Disconnect the electrical connectors to the transducers, located on the right side of the sump. (Fig 30).
5. There are two orange clips holding down the nozzle on the sump; one on the left and one on the right hand side of
the nozzle. On the left side, press in the clip with one hand and with the other lift the nozzle out of the clip. Repeat
this for the right side (Fig 31). The nozzle can now be lifted up and placed aside (Fig 32).
6. Gently lift up the sump (Fig 33), taking care to keep it level so as not to spill any water. Sit the sump in the sink.
7. Carefully empty the sump into the sink taking note that the transducer is held in place by a retaining clip.
8. Put a small amount of washing up liquid into the sump, and using a soft brush, gently clean all surfaces in the sump
and gently clean the transducer including the cone and metal discs located in the top grooved surface.
9. When cleaned, thoroughly rinse the sump with clean water to remove all traces of washing up liquid.
10. Clean the nozzle with a soft brush and flush out thoroughly with water.
11. Reverse the above steps 1 – 6 to reassemble.
Transducer
The transducer is a consumable item and may need to be replaced through time, depending on its usage. Replacement
transducers can be purchased from our your dealer. The transducer is fixed in the sump with a plastic clip. If you need
to replace your transducer:
1. Follow the steps 1-5 in the CLEANING - Sump section under 'Maintenance' to gain access to the transducer.
2. Press the clip back and lift the transducer upwards out of its holder.
3. Place the new transducer into the sump, ensuring the its cable does not sit over the cone.
4. Reverse the above steps to reassemble the nozzle and sump.
Air Filter
1. Gently lift out the fuel bed and place it aside.
2. Gently slide the air filter upwards out of its plastic holder. (Fig 34)
3. Gently rinse with water in the sink and dry with fabric towel.
4. Replace the filter making sure that the coarse black filter is facing outwards.
5. Replace the fuel bed.
CHANGING THE LEAK PREVENTION VALVE PAD
A leak prevention valve has been fitted to the appliance as an additional safety measure (Fig 35). In the unlikely event
that a leak occurs inside the product, the valve will prevent water from flowing to the product. When the valve has been
activated, the pad within the valve absorbs water and expands, shutting off the valve. It can be verified that the valve has
been activated if the pad has expanded and the arm of the valve is in its upper positon (Fig 36). If the valve has been
activated, the pad must be replaced. A spare pad has been supplied with the product, please follow the steps below to
change the pad.
1. In order to gain access to the valve, the nozzle and the sump must be removed first. Follow steps 1-6 above under
"Sump" to remove the sump and nozzle.
2. Verify that the valve has been activated by checking the orientation of the valve arm. If the pad has expanded and
the valve arm is in the upper position (Fig 36), the valve has been activated.
3. Remove the old expanded pad and dry the area around the valve. Replace the pad with a new pad, while ensuring
the new pad does not come into contact with water.
4. Close the arm of the valve on top of the newly fitted valve (Fig 37).
5. Replace the sump and nozzle and check that the product is operating by switching it on and ensuring water is
flowing into the sump. The product should be carefully inspected for leaks after replacing the valve.
Please note the product is not to be operated without the pad being fitted to the leak prevention valve.
If leaking persists after replacing the valve, contact your dealer or service agent.
