Installation - 5000, 4000, 4000 Classic, 3000 and 2000
Step1 - Fitting the sink bush assembly (See Fig.1 - Stage 1).
1.1) Remove the sink bush assembly from the unit by fi rst loosening the three-nuts (9), and twisting
the assembly clockwise in the hopper fl ange keyholes.
1.2) Slacken off the three-grub screws (7) suffi ciently to push the Suspension Plate (5) up the Sink
Bush (1) to enable you to remove the circlip (6) by twisting a fl at bladed screwdriver underneath
the clip at it's joint from the side, slide off all the components from the sink bush, with the
exception of the Inlet Gasket (2).
1.3) Position the sink bush in the sink waste outlet hole so that the line with the arrowhead and the
word GRIND is positioned at 9 o'clock relative to the front of the sink unit. Check that it is fl ush
or below the sink bowl surface and that it has a good seating. If not, remove the inlet gasket and
substitute with a layer of plumbers putty or suitable sealant.
FOR 4000 CLASSIC AND 2000
Position the sink bush in sink waste outlet hole so that the MAXMATIC engraving is at the front of the
sink i.e 6 o'clock. Check that it is fl ush or below the sink bowl surface and that it has a good seating.
If not, remove the inlet gasket an substitute with a layer of plumbers putty or suitable sealant.
1.4) From the underside of the sink, position the lower waste inlet gasket (3), followed by the clamp
plate (4) (with the outer edge is turned downwards). Push the suspension plate up onto the sink
bush as far up as you can, to reveal the groove around the sink bush that holds the circlip and
then push the circlip up the sink bush until it snaps into the groove.
1.5) You may now release the suspension plate and allow it to rest on the circlip and then rotate it
until the slot (see Fig.5) in the edge of the plates upper rim is in line with the pimple on the sink
bush. Tighten up the grub screws by hand a few turns to each in rotation so that the suspension
plate remains parallel to the clamp plate. see fi g 4. Finally, tighten with a screwdriver Do Not
over-tighten the grub screws, as this will cause distortion of the Suspension Plate.
Step 2 - Fitting the unit to the sink bush assembly (Fig.1 - Stage 2).
2.1) Fit the Hopper Seal (8) on to the three grub screws fl attest side up, the bottom edge of the sink
bush will locate in the recess on the top of the seal.
2.2) Fit the three nuts and washers, to the grub screws only a few turns.
2.3) Offer up the disposer with the control box facing towards you ensuring that the nuts and washers
fi t through the large holes of the keyholes and turn the disposer clockwise, so that the grub
screws move into the keyhole slots and rest the disposer on the washers above the nuts.
2.4) Tighten up the three nuts evenly ensuring that the hopper seal is correctly seated. DO NOT over-
tighten the nuts as this will cause the hopper seal edge to bulge into the waste inlet, which will
hamper the movement of the Magnitop Plug. Over tightening may also cause the hopper to distort
resulting in a leak.
Step 3 - The disposer is now ready for the waste plumbing and electrical connections.
3.1) If required the bottom half of the disposer with the waste outlet can be rotated to make the
plumbing easier. To do this slightly slacken off ALL six bolts around the underside rim of the
hopper (if one is not slackened the hopper seals may be twisted out of position and the cutter
ring could be misaligned). Gently rotate the lower section of the unit to the required position and
tighten the six bolts (see Fig.2).
3.2) Connect to the drain and electrical supply by following the general instructions on page 4.
Step 4 - Testing
4.1) Insert the Magnitop Plug into the sink outlet and turn to the "SEAL" position and half fi ll the
sink with water and check for leaks around the underside of the sink (The 4000 model does not
include a Magnitop plug so the stainless steel plug supplied is used). Turn the Magnitop plug to
the 'DRAIN' position and check all joints for leaks.
FOR 4000 CLASSIC AND 2000
Insert the plug into the sink outlet and half fi ll the sink with water and check for leaks around the
underside of the sink. Remove the plug and check all joints for leaks.
4.2) Set the switch on the front of the control of the unit to the 'ON' position (Fig.3) Please note that the
switch is not used to activate the machine and is merely supplied as a means of reversing cutting
rotation. Check the power and test the operation of the unit by following the instructions on page 3.
4.3) Attach proof of purchase to this booklet and keep it in a safe place with the de-jam key. Don't
forget to return the registration card within 14 days together with a copy of your proof of
purchase to extend your warranty. If not registered 12 months statutory warranty will apply.
