PIPER INSTALLATION

Connecting your new PIPER

ELECTRICAL SUPPLY

• A 115 Volt -15 Amp circuit breaker is required for this washer (please make sure that this outlet is grounded). A standard
power-cord with plug is provided for your convenience for the 115 Volt version.

• NOTE: If you have purchased the optional 208 Volt version, the rear access panel must be removed prior to making
connections. The circuit used for this unit should be independent from any other equipment. (Make sure that the power stays
within the prescribed voltages).

WATERSUPPLY

• A 3/4" garden hose coupling is required with 30 p.s.i. dynamic pressure. A water pressure regulator is required. The water
pressure cannot exceed 50 p.s.i. If the water pressure exceeds the prescribed amount, you will get inconsistent washing
temperature and thus may void the warranty.

• Incoming water temperature must be 140° F (60° C). An easily accessible shut-off valve is recommended — making
installation, service and repairs easier.

• The diameter of the fitting required is 3/4" ID. This size hose is standard for most warewashing machines. Fittings should be
available from your local hardware or plumbing supply house.

• Flexible hoses are highly recommended to make installation, servicing and maintenance easier.

• Make sure that the water is free from calcium and hard water deposits. For these situations, an on-line water cartridge system
is highly recommended. Build -up of calcium and lime deposits in the washer may occur and servicing will be required on a
more frequent basis which will not be covered by the warranty.

DRAIN CONNECTION

• This washer has a gravity type drain. Since this unit is a 'counter-type' installa tion,
your flexible drain hose, should be connected to the drain outlet elbow at the rear of the
unit behind the rear access panel; and extended through the side opening directly into a
floor drain or sink (see Figure)

Before operating the machine, ensure that power is supplied to the machine (verify the breaker) and that the
water supply is correctly fixed on the machine. Also verify that the overflow pipe is correctly set in its place
(inside the wash tank). The overflow pipe should never be forced into its position.

• The main power switch (square green button on the right side) must be activated.
When the wash tank is empty and the overflow pipe is in its place, the machine will fill up to its requir ed
water-level. Always keep the door closed during this time. When the machine is done filling up, the elements
will then raise the wash and rinse water temperatures automatically. It will take approximately 10-12
minutes in order to get optimum washing te mperature (140°F in the wash tank and 18 5 °F in the booster). A
pilot light will turn ON to indicate that the machine is ready for its first load.

• Fill the basket with glasses and cups then push the basket into the machine. If you are using dry soap

detergent or crystals, put the required amount (usually about one full tablespoon) inside the door and close.
If you are using liquid soap detergent, a chemical pump system will take care of adding the right amount of
soap for each batch. DO NOT use domestic liquid dish soap, only commercial grade.

• NOTE: Whenever you start with the initial fresh water after fill-up, it is recommended to place one

tablespoonful of detergent (if you are using powder soap) on the filters in addition to the regular amount per
batch. Use soap as recommended by your supplier. Using too much may cause damage to the pump seals.

• It is more economical to wash when the basket is fully loaded. It is also important not to overload the basket.

Water should always be able to spray freely around the cups and glasses.

• Press the cycle start switch (round black button on the right). This switch will power the timer and a pilot

light beside it. It may be necessary to press and hold the switch for one full second to begin the cycle.

A. The cycle starts and consists of a 165 second wash and a 15 second rinse time.

B. Another basket can be filled while the first one is being washed. After 180 seconds, the pilot light

turns OFF to signal the end of the cycle.

C. NOTE: It is recommended to change the wash water at least twice per day (after each peak

period). To do this, turn the green power switch to the off position. Pull up the overflow pipe and
allow the machine to drain fully.

D. Clean the tank filter. Flush the tank out with clean water. Put back the filter and overflow pipe in

their proper location. Close the door and turn the power back ON. Turn off machine and drain the
washer at the end of the day or if the machine will not be in use for more than a few hours.
