Unpacking

• Unpack the chipper immediately after receipt. Please inspect the chipper to ensure no damage and all parts are present including the knife block assembly (supplied separately).
• If the machine is found to be damaged, keep all the packaging material and contact us immediately or contact your source of the equipment.

• 1 x Knife Block Assembly (ordered separately)
• If any of the above items were not received with your chipper, please refer to for contact details and inform us immediately for replacements.

Installation

1. Before using the chipper please read this manual thoroughly. DO NOT proceed with any installation or operation if you have any questions or do not understand anything within this manual. Please see the contact details for assistance.
2. Carefully unstrap the chipper from the pallet.
3. Select a location for the chipper keeping these key points in mind:
   • The floor or counter must be level
   • Work surface or bench, trolley, or stand, must be able to support a load of 75kg
   • Easy access for maintenance and servicing
   • Clearance for operating/opening the hopper
   • Sufficient space above the hopper to load the potatoes
4. If you purchased the Floor Stand or Floor Trolley, position the chipper on this before use, ensuring that the air vent opening on the stand is under the rear of the machine.
5. Please read the electrical information found on the data plate located at the rear of the machine. The incoming power should match the rating on the data plate.
6. The Electric Chipper 20 (EC20) comes with a fused 13 amp molded plug. The electrical supply should be connected via a 30A isolator providing at least 3mm separation in all poles.

Model| Voltage / Hz| Phase (Ø)| Load Current| Fuse Rating per phase| kW / hp
---|---|---|---|---|---
EC20| 230 / 50| 1| 5.0 Amps| 13 Amps| 0.18 / 0.25

• The supply to the machine must also be protected by a 30mA RCD.

Noise Test Report

• The average A-weighted sound pressure level is 63 dB.

Operation

• Press the start button and with the machine running, feed wet, peeled potatoes into the hopper. It will hold approximately 20kg of potatoes, which self-feed into the mechanism of the machine and discharge as cut chips from the chute.
• NOTE: do not leave the chipper unattended whilst in use.
• Some care is necessary when loading, as the rotor will not accept abnormally large potatoes, so these must be cut into two. The hopper is specially designed not to pass potatoes that are oversize, and which could otherwise clog the mechanism.
• The potatoes must be fed into the machine steadily and not emptied into the hopper all at once as this could lead to the rotor jamming.
• It is also essential that only potatoes be fed into this machine.
• NOTE: take great care to ensure that there are no stones mixed in with the potatoes.
• A stone or any other foreign object will damage the cutting knives and could cause the machine to jam. In this event, the machine has an inbuilt protection device, which will switch it off before the electric motor burns out.
• This overload protection feature will automatically reset itself when it cools down, but it is necessary to wait a few minutes for this to happen. After clearing the jam resume operation by pressing the start button.
• Should a stone damage the knife blades they must be replaced as further use could break the blades.
• This chipper is designed for batch process work; switch the machine off once all the potatoes have been cut. The motor is fitted with a thermal trip that will stop the machine if the motor overheats.
• This protection feature will automatically reset itself when it cools down, but it is necessary to wait a few minutes for this to happen.
• The machine will switch itself off in the event of failure of the electricity supply whilst operating. When the supply is restored, the machine must again be switched on. It is fitted with no-volt release.

Changing Chip Size

• To change to a different size of the chip, change the knife block assembly. Spare knife block assemblies are available from Metcalfe.
• Open the hopper, lift out the knife block, and replace it with the alternative selected.
• Knife blocks are available in the following sizes from the standard range: 10mm, 12mm, 14mm, and 16mm.

Cleaning Instructions

• ALWAYS disconnect or unplug the electrical power from the chipper before cleaning.
• NEVER use a scrubber pad, steel wool, or abrasive material to clean the chipper.
• NEVER use bleach or bleach-based cleaner.
• ALWAYS remove the knife assembly after each batch otherwise the assembly can become stuck on the locators and difficult to remove.
