Installation
Water Supply Connection
The water inlet nozzle connector is supplied and should be fitted to the outside
of the machine facing upwards. It has two possible inlet locations, one on either
side of the machine, whichever is more convenient for your installation.
1. Thread the water inlet valve (1) onto the elbow joint (2), ensuring a fibre
washer (4) is placed between the two.
Ensure the valve is tightened securely to eliminate leakages.
2. Take the water inlet bush (3) with a fibre washer (4) placed over it and feed
through the chamber wall from the inside.
3. Place another fibre washer (4) onto the water inlet bush on the exterior side of the chamber. Take
the assembly from step 1 and thread the remaining elbow joint opening onto the water inlet bush.
Ensure the assembly is tightened securely to eliminate leakages. Also ensure the water inlet
valve is pointing directly upwards, otherwise the air gap does not function correctly.
Connect the water supply pipe to the water inlet, connect the other end of the supply pipe to a cold water
tap or shut off valve that can be used to supply a sufficient water flow into the machine.
Waste Outlet Connection
The waste outlet is screwed onto the right-hand side of the machine but can be
used on either side of the machine to suit your installation. Pipe work for the
waste outlet can be purchased from a hardware store, or we can supply as an
optional extra a waste pipe, elbow and coupling. This is to be fitted to the waste
outlet casting to discharge the waste into a sink.
Having connected the water inlet, waste outlet and the electrical supply, the machine is ready for
operation.

Installation of Optional Extras
Installation Kit (optional extra)
Comprises a Sink
Skip, Length of
Waste Pipe, Elbow &
Coupling, 3ft Length
Water Inlet Hose &
Tap Connector.
This image shows a typical installation utilising the kit.
Waste Disposal Adaptor (optional extra)
The waste disposal adaptor enables the waste pipe to be connected direct to
the drain. It gives an additional water supply to the waste outlet to flush
away the sludge.
The waste disposal adaptor fits onto the waste outlet
on the side of the peeler. Ensure that the waste
disposal adaptor is vertical and securely in place.
Two adjusting screws and lock nuts are provided to
adjust the water flow through the machine. The top
one controls the flow through the peeler and the
lower one controls the flow to the waste pipe.

7
Small External Interceptor (optional extra)
This image shows a typical external interceptor
installation.
Tundish (optional extra)
The use of a tundish meets the requirements of water regulations
G19.1, G19.3 & G19.4 contained in “The Water Supply Regulations
1999” and the “Water Byelaws 2000 (Scotland)”.
The tundish can be fitted instead of the standard water inlet nozzle
supplied with all Metcalfe peelers.

8
Operation
Full operational instructions can be found on the side of each peeler.
The machine works off 230volt 50Hz 1 Phase supply and comes fitted with a 3-pin 13amp fused plug.
1. Ensure that the chute door is closed.
2. Turn on the machine by pressing the green start button.
3. Turn on the water supply.
4. Remove the rubber lid and load the potatoes through the top of the peeler and replace the lid.
DO NOT load the potatoes before running the unit as this will damage the bearings, shaft
assembly & motor and will void the warranty.
5. Carefully remove rubber lid to check peeling progress.
6. Once peeled, open the door whilst the machine is still running to discharge the potatoes into a sink
or bucket.
7. Once empty, you can then switch the machine off.
DO NOT at any point put your hand or any implement into the machine, whilst it is in
operation.
Cleaning Instructions
Daily cleaning should be considered mandatory for all equipment used in the preparation of food. Once
your peeler has made contact with any food product, the entire peeler, including removable parts must
be thoroughly cleaned. This process is to be repeated essentially at least once a day, or at the end of
each operation period. If the machine has not been used for a while it must be cleaned before use as
well.
1. Switch off unit at socket.
2. Remove metal lid.
3. Unscrew the fixing screw securing the rotor plate using the box spanner provided.
4. Lift out the rotor plate using the lifting hook provided.
5. Turn on cold water supply to clean the inside of the chamber with a nylon brush.
6. To clean the rotor plate, wash in cold water ONLY using a nylon brush.
NEVER wash the plate in hot water or in a dishwasher as this will remove the coating.
7. Use a damp cloth to wipe the outside of the unit.
DO NOT use cleaning materials containing abrasives or bleaches.

9
Maintenance
How to Adjust Door Cam
Over time the door may loosen slightly. If this happens a door cam has been fitted to enable the
operator to retighten the door.
1. Undo the nut underneath the chute
to loosen the cam.
2. Turn the door cam into position so that the door handle can
be locked in place securely.
3. Retighten the nut to secure the door cam into its new and
correct position.

Service
Disassembly Instructions
1. Remove rubber lid and aluminium lid.
2. Undo the rotor plate fixing screw using the box spanner provided and lift the rotor plate using the
lifting hook provided.
3. Unscrew sweeper casting and remove.
4. Turn machine upside down and remove v-belt.
5. Release locking nut & screw which holds the pulley in place and remove pulley.
6. Knock out spindle down into the peeling chamber.
7. Undo the three screws which hold the bearing retainer washer, located underneath the pulley, and
remove.
8. Stand machine back upright & take out the spindle assembly. (The spindle is threaded onto the
sweeper. If difficulty is being experienced in removing the sweeper, it may be necessary to place the
spindle in a vice to be able to release it from the sweeper).
9. If necessary, remove any remaining part of the bearings on the spindle and inside the peeling
chamber housing, if original spindle is to be reused.
DO NOT re-use spindle if it is damaged.
Water Inlet Valve Assembly Instructions
4. Thread the water inlet valve (1) onto the elbow joint (2), ensuring a fibre washer (4) is placed
between the two.
Ensure the valve is tightened securely to eliminate leakages.
5. Take the water inlet bush (3) with a fibre washer (4) placed over it and feed through the chamber
wall from the inside.
6. Place another fibre washer (4) onto the water inlet bush on the exterior side of the chamber. Take
the assembly from step 1 and thread the remaining elbow joint opening onto the water inlet bush.
Ensure the assembly is tightened securely to eliminate leakages. Also ensure the water inlet
valve is pointing directly upwards, otherwise the air gap does not function correctly.
Bill of Materials:
1. Water Inlet Valve (PW08 X 1)
2. 3/8” BSP Stainless Steel Elbow (PE02 X 1)

Shaft & Bearing Assembly Replacement
1. Turn the machine upside down and fit the bottom bearing into the housing from underneath the
machine, ensuring it is flush with the base of the peeler.
2. Stand the machine back upright and fit the first bearing along with the bearing spacing collar onto
the shaft.
3. Fit the second bearing along with the bearing spacing collar on to the shaft, and fit shaft through
the first bearing, from inside the unit. Tap the shaft gently into place with a mallet, making sure that
the bearing is fitted properly (the bearing should be flush with the casting or just below it).
4. Turn the machine upside down and refit the bearing retaining washer, securing it with the three
screws.
5. Fit the deflector disc to the shaft (turned down outer edge facing downwards), securing with the
silicon adhesive supplied. Allow to dry for 24 hours.
6. Turn the machine upside down and refit the pulley and belt.
7. Stand the machine back upright and fit the oil seal over the shaft, so that it is flush with the
deflector disc.
8. Re-screw the sweeper and fit the rotor plate back into place, securing with the rotor plate fixing
screw.
9. Refit the top casting and rubber lid.

12
V-belt Tensioning Instructions
1. Turn machine on its front so that the motor is on top and the machine is sitting on its door (if a
guarded discharge chute is fitted please remove before attempting this).
2. Lubricate supply cable with washing-up liquid. Pull cable through cable grommet into the motor
cover (enough to allow removal of the motor cover).
3. Remove the motor cover by unscrewing the four screws on the motor housing cover.
4. Loosen the four top nuts holding the motor in place.
5. Tensioning of the belt can be done by adjusting the four bottom nuts on the motor studs.
6. Once you have the correct tension, tighten the four top nuts to re-secure the motor into place.
7. Refit the motor cover and pull the cable back out.
