These will normally be installed on a work top of some sort or on a draining board. Peeled
potato discharge is commonly into a sink and the sludge discharge can be piped away
separately, possibly using a waste ejector fitting. Alternatively, with lightly used machines the
waste can be directed via an outlet elbow into a sink skip acting as a strainer in the sink.
1 To fasten down the base unit, take off the motor cover. With the cover off, the two
fastening down holes will be visible just forward of the electric motor.
2 Place the base assembly in the required position and mark down through these holes.
3 Remove the base and drill holes through the work top in the marked position.
4 Replace and bolt down using long bolts and nuts (M8 x 95mm are suitable sizes for work
tops of 25mm thickness).
When fixing to a wheeled trolley these same holes are utilised, but the bolts are supplied with
the trolley outfit.
Then proceed with Supply Connection Instructions.

Examine the rating plate attached to the machine to ensure that the characteristics shown are
correct for the supply available.
The control switch should be as near to the machine as the length of cable will allow. If this is
not possible, provided the extra length is not considerable, the cable can be replaced with a
longer piece of the same specification. Unless a jointing box is used DO NOTDO NOT

DO NOT splice cable
together but replace with a complete new length back to the terminal box.
The control should be a motor starter but a 13 amp fused or 15 amp round pin switch socket
will serve. These must be 3 pin and EARTHED and on no account must a 5 amp lighting point
be used. Fuse with a 13 amp fuse to BS1363. Three phase machines should be connected to
a 15 amp three pole isolator fused at 5 amps.
When using a motor starter, follow the instructions supplied with it.
New mains supply run to the machine should always be undertaken by a reputable and
competent electrician. The IEE Codes of Practice must be observed.

Connections should only be made from a storage tank supply and not directly from the mains.
1/2" bore canvas reinforced hose with hose clips at the ends should be used for the final
connection. Allow sufficient length for the top of the machine to be removed and placed aside
when cleaning without straining or disconnecting the hose. Do not use rigid piping as this will
make internal cleaning difficult unless the machine is dismantled first.
If the supply is taken from a sink tap a Royles Union connection will suffice. Permanent
installations should, however, have a wall mounted control cock fitted with a 1/2" BSP
threaded outlet and hose union.

The length of run between the machine and the main junction must be kept to a minimum and
the pipe must have a fall of at least 1:15. Changes of direction should be made by bends
rather than elbows and cleaning eyes should be fitted where possible, in accordance with
standard plumbing practice.

Machines installed on a draining board can be provided with a sink skip straining basket to
prevent sludge blockage of sink drain outlet pipe. A special outlet elbow is provided for this
purpose.
A trap is not necessary if the discharge is into a gully or an intercepting tank although a trap
must be provided in the outlet pipe away from an intercepting tank. A trap is necessary if the
outlet pipe connects directly into a drain. When using an intercepting tank, run waste outlet to
discharge direct into the sludge basket. The waste outlet must not obstruct removal of the
basket.
Another adaptation is to couple the outlet to an IMC Waste Disposer. This disposes the sludge
from the potato peeler swiftly and efficiently while retaining its invaluable services as a normal
food waste disposer.
WASTE EJECTORWASTE EJECTOR
WASTE EJECTORWASTE EJECTOR
WASTE EJECTOR
The waste ejector is a fitting which dilutes the sludge effluent to enable it to flow easily through
the drains without fear of blockage.
Waste ejectors are not recommended in the following circumstances:
1 A pipe run exceeding 15m between the machine and main drain.
2 When a fall of 1:15 cannot be achieved.
3 When the piping is exceptionally complex.
In any of these cases, use instead an interceptor tank. Water for the ejector must be taken
from a storage tank not from a rising main, and must incorporate a stopcock.
Should the head of water from a storage tank be lower than the recommended 3m head it is
necessary to drill out the jets in the ejector to 6mm diameter or refer back to the
manufacturers for advice. The unit incorporates an air break to prevent back siphonage.

If the waste ejector is not fitted to the peeler when it is arrives, proceed as follows:
1 Remove existing waste outlet from the peeler.
2 Decide on which side the outlet pipe is to be connected and, if necessary, remove cover
plate and gasket from the alternative waste outlet and refit to the original.
3 Fit ejector unit and gasket in place of the waste outlet.
4 The ejector unit has a 1/2" BSP connection for water supply on each side of the unit.
Select which is to be used for water connection and use the plug for sealing off the other.
5 Connect the rubber hose between connector at the top of the unit and sprinkler at the top
of the cylinder.
6 Proceed with the installation of the waste pipe.

When the pipework is complete proceed with adjustments designed to give correct water
regulation to the machine. Two adjusting screws and lock nuts are provided for this purpose.
The top one controls the flow through the peeler, the lower controls the jet to the waste pipe.
Slacken off the lock nuts and turn water supply full on. Adjust the top screw until the flow
through the machine is between 2.25 and 7 litres per minute, then tighten the lock nut. Set the
lower screw to allow a healthy jet of water into the waste pipe of 2.25 to 3.5 litres per minute.
Judge the flow by inspecting the jet through the air break. Tighten the lock nut.

Operation
1 Measure the potatoes into a container which holds a known measured weight and take
out any stones which could jam the machine or damage the abrasive. Should this
happen, the noise will indicate the presence of a stone; switch off immediately and
remove it.
2 Turn on the water before loading the potatoes. Set timer to required run length and press
'start'. A prolonged operation cuts into the potato body and induces foaming in the waste
pipe. Remember that firm potatoes peel faster than soft ones.
3 On completion of the cycle, switch off the water supply, restart the machine and open the
chute door. This will discharge the potatoes. ON NO ACCOUNTON NO ACCOUNT
ON NO ACCOUNTON NO ACCOUNT
ON NO ACCOUNT put hand or implement
into the machine.
4 Keep the finished potatoes under water until required for cooking.
A new machine will give a peeling cycle of 3/4 minute. This lengthens to about 1 minute after
the initial period of the machine’s life. Remaining constant for a considerable period the peeling
cycle will eventually become more and more prolonged. This signals wear in the abrasive
which should then be replaced.
The machine will initially provide a finished potato with a surface somewhat rougher than you
may wish. This brief disadvantage however, enables a longer life of the abrasive to be
ultimately achieved.
