GUARANTEE
This machine is guaranteed by IMC for twelve months 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 700 & 800 Series Disposers have a 2” BSP female threaded outlet which is
designed to be connected to 54mm copper or plastic piping. 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 rotated at 90° intervals by unbolting the waste
outlet casting from the hopper flange plate. Rotate the motor and waste outlet
casting to the required orientation. Check that the gasket between the waste
outlet casting and the flange plate is in place. Refit the nuts and bolts and tighten
uniformly all round. Do not over tighten, but ensure that the gasket is nipped
firmly and the hopper is rigidly fixed without any distortion of its bottom flange.
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
waste outlet of the waste disposer. Failure to do this will prevent the machine
from draining completely.

WATER SUPPLY CONNECTION
A cold water supply with a minimum head of 0.2 to 10 bar is required. This is
connected to the units at the water control valve using a 15mm compression joint,
supplied with the machine. A stopcock should be fitted to the water supply.
The rate of water flow for the disposal of normal food waste is 14-18 litres per
minute for 700 Series machines and 18-27 litres per minute for 800 series
machines. Adjust the water supply control valve to achieve the desired flow rate.
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.
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 700/800 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, derate accordingly.
Unit
Voltage
Full Load Current Fuse Rating per
Phase
700 400-3-50 2.8 Amps 5 Amps
440-3-60 2.6 Amps 5 Amps
230-1-50 7.4 Amps 15 Amps
800 400-3-50 5.3 Amps 15 Amps
440-3-60 5.1 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.

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:
723 Disposer
1. Switch off at the mains isolating switch.
2. Take out any bulk waste in the baffle chamber. Rubber gloves are
recommended
3. Lower the release wrench though the aperture in the baffles and locate
between the hexagonal boss on the centre of the rotor and the vane of the
rotor. Exert pressure in both directions until the jammed material releases.
4. Remove the release wrench
5. Switch on at the mains isolating switch.
6. Press the START button and continue disposal.
725, 726 and 800 Series Disposers
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. If the item which blocked the disposer is apparent, remove it.
4. Place the hexagon socket of the release wrench over the central hexagonal
boss on the rotor and lever backwards and forwards until the jammed
material releases. Remove the release wrench and pull out the material.
5. Replace the wrench and ensure that the rotor is totally free throughout its full
rotation. Remove the release wrench.
6. Replace the baffle, screwing the interlock knob fully home.
7. Switch on at the mains isolating switch.
8. Press the START button and continue disposal.
