500 Series Food Waste Disposer 1
GUARANTEE
This machine is guaranteed by IMC for 1 Year from the date of purchase from
IMC or from one of its stockists, dealers or distributors.
The guarantee is limited to the replacement of faulty parts or products and
excludes any consequential loss or expense incurred by purchasers. Defects
which arise from faulty installation, inadequate maintenance, incorrect use,
connection to the wrong electricity supply or fair wear and tear are not
covered by the guarantee.
PLEASE OBSERVE THESE INSTRUCTIONS CAREFULLY
This guarantee applies in this form to installations within the UK only.
WASTE OUTLET CONNECTION
All 500 Series Disposers are fitted with a neoprene housing which is designed
to couple to a 42mm copper or plastic fitting, lead piping should not be used.
The size of the waste outlet must not be reduced. A running trap should be
fitted although ‘P’ or ‘S’ type traps can be used. Do not fit a bottle trap. The
length of run between the machine and the main junction must be kept to a
minimum and the pipe must have a positive fall of at least 1 in 7. Changes of
direction should be made with swept bends rather than elbows, and cleaning
eyes should be fitted where possible, in accordance with standard plumbing
practice.
The waste outlet position can be changed by loosening the hose clip at the
top of the neoprene housing. The motor and housing can then be rotated until
the outlet is in the required position. Tighten the hose clip once the outlet is in
the required position.
All Waste Disposers must have an independent drain pipe that does not also
serve sinks, dishwashers or similar equipment. The end of the waste pipe
must be beyond any grease traps and if the outlet feeds into an outside gully,
the pipe should enter the gully below the covering grid. Use a back entry yard
gully.
When fitting the trap make certain that the top invert of the trap lies below the
rubber outlet spout of the waste disposer. Failure to do this will prevent the
machine from draining completely. Also ensure that on all models the outlet
tail does not enter the outlet spout beyond the register, if this tail is fitted to
deeply into the spout it will obstruct the outlet flow
The 523 Disposer is sink mounted and the neoprene housing contains an inlet
boss for the sink overflow near the top of the housing. If this is required the
center of boss needs to be cutout before the overflow is connected.

2500 Series Food Waste Disposer
WATER SUPPLY CONNECTION
A cold water supply with a minimum head of 4m is required on the 525 and
526 Disposers. This is connected to the units at the solenoid valve using a
15mm compression joint, supplied with the machine. A stopcock should be
fitted to the water supply. The 523 disposer draws its water supply from the
sink tap.
The 500 series machine is to be fed by a cistern tank not mains water supply.
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 plate
attached to the motor to ensure that the characteristics shown are correct for
the supply available. The cables fitted to the controller are the minimum
required for individual connection to the mains supply. Site conditions may
vary with additional length of cable run, encapsulation in trunking, bunched
with other cables etc. Should this apply, the electrician must alter the cable
accordingly.
All machines are supplied with a starter with forward, reverse and stop
buttons. Where automatic water control is supplied the starter also controls
the water flow. This unit must be connected to the mains supply using the
starter provided. Omission of the starter eliminates overload protection for the
motor and will invalidate the guarantee.
The 500 Series Disposers should be connected to a 30A isolator providing at
least 3mm separation in all poles. The table below illustrates typical fuse
ratings for an ambient temperature of 25 to 35°C. Should the environment
temperature be greater than this, adjust accordingly.
Voltage Full Load Current Fuse Rating per Phase
230 – 1 – 50 5.0 Amps 13 Amps
115 – 1 – 60 10.0 Amps 13 Amps
220 – 1 – 60 5.6 Amps 13 Amps
254 – 1 – 60 5.2 Amps 13 Amps
400 – 3 – 50 1.7 Amps 5 Amps
220 – 3 – 50 3.0 Amps 5 Amps
230 – 3 - 60 2.7 Amps 5 Amps
440/460 – 3 – 60 1.7 Amps 5 Amps
The supply to the machine must also be protected by a 30mA RCD.
Warning: This appliance must be earthed.
If the supply cord becomes damaged it must be replaced by qualified
electrician in order to avoid a hazard.

500 Series Food Waste Disposer 3
RELEASING A JAM
Food Waste Disposers can jam under overload or if unsuitable materials are
placed 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 disposal chamber. Rubber gloves are
recommended
4. If the item which blocked the disposer is apparent, remove it.
5. A release wrench is provided 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 pull out
the material.
6. Replace the wrench, engaging the hexagon and ensure that the rotor is
totally free throughout its full rotation.
7. Remove the release wrench
8. Replace the baffle, screwing the interlock knob fully home.
9. Switch on at the mains isolating switch.
10. Press the START button and continue disposal.
NOTE
Single phase motors have a thermal overload switch built into the motor. If a
jam occurs and the motor cuts out then a cool down period of approximately
40 minutes will be required before the unit will restart. The thermal overload
will reset itself during this period. Do not try and restart the FWD before the 40
minute time period is over and the motor has cooled down. Doing so could
cause unnessasary damage to the motor.
