GUARANTEE
This machine is guaranteed by IMC for 1 Year from the date of urchase from IMC or from
one of its stockists, dealers or distributors.
The guarantee is limited to the re lacement of faulty arts or roducts and excludes any
consequential loss or ex ense incurred by urchasers. Defects which arise from faulty
installation, inadequate maintenance, incorrect use, connection to the wrong electricity
su ly or fair wear and tear are not covered by the guarantee.
Please obse ve these inst uctions ca efully
This guarantee a lies in this form to installations within the UK only.
WASTE OUTLET CONNECTION
All 500 Series Dis osers are fitted with a neo rene housing which is designed to cou le to
a 42mm co er or lastic fitting, lead i ing should not be used. The size of the waste
outlet must not be reduced. A running tra should be fitted although ‘P’ or ‘S’ ty e tra s
can be used. Do not fit a bottle tra . The length of run between the machine and the main
junction must be ke t to a minimum and the i e must have a ositive fall of at least 1 in
7. Changes of direction should be made with swe t bends rather than elbows, and cleaning
eyes should be fitted where ossible, in accordance with standard lumbing ractice.
The waste outlet osition can be changed by loosening the hose cli at the to of the
neo rene housing. The motor and housing can then be rotated until the outlet is in the
required osition. Tighten the hose cli once the outlet is in the required osition.
All Waste Dis osers must have an inde endent drain i e that does not also serve sinks,
dishwashers or similar equi ment. The end of the waste i e must be beyond any grease
tra s and if the outlet feeds into an outside gully, the i e should enter the gully below the
covering grid. Use a back entry yard gully.
When fitting the tra make certain that the to invert of the tra lies below the rubber
outlet s out of the waste dis oser. Failure to do this will revent the machine from draining
com letely. Also ensure that on all models the outlet tail does not enter the outlet s out
beyond the register, if this tail is fitted to dee ly into the s out it will obstruct the outlet
flow
The 523 Dis oser is sink mounted and the neo rene housing contains an inlet boss for the
sink overflow near the to of the housing. If this is required, the centre of boss needs to be
cut out before the overflow is connected.

500 SERIES FWD
WATER SUPPLY CONNECTION
A cold water su ly with a minimum head of 4m is required on the 525 and 526 Dis osers.
This is connected to the units at the solenoid valve using a 15mm com ression joint,
su lied with the machine. A sto cock should be fitted to the water su ly. The 523
dis oser draws its water su ly from the sink ta .
The 500 series machine is to be fed by a cistern tank not mains water su ly.
ELECTRICAL CONNECTION
All electrical work must be carried out by a qualified electrician and in accordance with the
IEE Codes of Practice. Examine the rating late attached to the motor to ensure that the
characteristics shown are correct for the su ly available. The cables fitted to the controller
are the minimum required for individual connection to the mains su ly. Site conditions
may vary with additional length of cable run, enca sulation in trunking, bunched with other
cables etc. Should this a ly, the electrician must alter the cable accordingly.
All machines are su lied with a starter with forward, reverse and sto buttons. Where
automatic water control is su lied the starter also controls the water flow. This unit must
be connected to the mains su ly using the starter rovided. Omission of the starter
eliminates overload rotection for the motor and will invalidate the guarantee.
The 500 Se ies Dispose s should be connected to a 30A isolato p oviding at least 3mm
sepa ation in all poles. The table below illustrates ty ical fuse ratings for an ambient
tem erature of 25°C to 35°C. Should the environment tem erature be greater than this,
adjust accordingly.

MAINTENANCE
WARNING: BEFORE ATTEMPTING SERVICE WORK ENSURE THAT ELECTRICITY AND WATER
SUPPLIES ARE TURNED OFF AT THE MAIN SUPPLY AND STOP COCK
12 Monthly, All models
Check the motor seals for wear by removing the motor and disassembling.
It is impe ative that the moto seals a e checked at least eve y 12 months and eplaced if
necessa y. Failu e to maintain the seals will esult in wate ing ess to the moto .
Check for bearing wear by the sound of motor and side to side movement of rotor
Regular ins ection of catering equi ment can extend its working life. Please hone IMC for
details of service contracts.
DO’S AND DON’TS
DO ENSURE CONTROLS AND ISOLATOR ARE ACCESSIBLE TO THE DISPOSER
OPERATOR
DO SWITCH ON DISPOSER BEFORE INTRODUCING THE WASTE
DO CLEAN THE MACHINE AFTER EACH PERIOD OF USE
DON’T PLACE HANDS INSIDE THE UNIT WHILST MACERATOR IS SWITCHED ON
DON’T PLACE CLING FILM, LIQUID FAT, STRING, CLOTH, PLASTIC, WIRE, GLASS, CORK,
STYROFOAM, BOILING WATER, HOT SOUP, HOT LIQUID OR METAL OBJECTS
INTO THE MACHINE
DON’T USE CLEANING MATERIALS CONTAINING ABRASIVES OR BLEACHES
DON’T STEAM CLEAN THE MACHINE

RELEASING A JAM
Food Waste Dis osers can jam under overload or if unsuitable materials are laced inside.
IMC machines are designed to withstand this and no damage will normally result as the
machine will switch itself off. It is necessary to clear the jam as follows:
1. Switch off at the mains isolating switch.
2. Remove the baffle by unscrewing the interlock knob and lifting off.
3. Take out any bulk waste in the dis osal chamber. Rubber gloves are recommended
4. If the item which blocked the dis oser is a arent, remove it.
5. A release wrench is rovided with which to turn the rotor if it is jammed. Place the
hexagon socket of the wrench over the hexagonal boss on the centre of the rotor
and lever backwards and forwards until the jammed material releases. Remove the
release wrench and ull out the material.
6. Re lace the wrench, engaging the hexagon and ensure that the rotor is totally free
throughout its full rotation.
7. Remove the release wrench.
8. Re lace the baffle, screwing the interlock knob fully home.
9. Switch on at the mains isolating switch.
10. Press the START button and continue dis osal.
NOTE
Single hase motors have a thermal overload switch built into the motor. If a jam occurs
and the motor cuts out, then a cool down eriod of a roximately 40 minutes will be
required before the unit will restart. The thermal overload will reset itself during this
eriod. Do not try and restart the FWD before the 40-minute time eriod is over and the
motor has cooled down. Doing so could cause unnecessary damage to the motor.
