Chemical Feeder Tubes

Before placing the Glass Washer in its permanent position extend the chemicals feeder tubes making sure not to kink.

Chemical Feeder Tubes

• R: Rinse Aid – Blue Pipe
• D: Detergent – Clear Pipe

Note – Do not add extensions to chemical feeder tubes.

Note – Chemical supply containers must be placed as close to the machine as possible and must NOT be elevated.

Note – Reposition the chemical tubing at the back of the machine, ensuring there are no kinks, before placing the machine in its permanent position.

Plumbing Connection

Water Connection

Note – Plumbing connections must be made in such way that will allow the machine to be removed for service and cleaning.

1. Connect the hose supplied with the machine to the inlet at the rear of the machine and the ¾” NPT fitting on the water supply line.
2.  Check the water inlet pressure is between 2-4 bar (29-58 psi) (not static). If it is more a PRV (pressure reducing valve) must be installed. If it is less a booster  pump will be required.

Descaling

In hard water areas hmescale can build up within the appliance after prolonged use. For best taste and extended appliance life, descale it regularty. Installation of a water filtration system is also recommended.

Note: Use a suitable de-scaler and always follow the instructions on the container. BUFFALO recommend that this appliance is de-scaled every 3 months or more frequently in hard water areas.

DW464 Only

Note – This machine drains by gravity so the drain pipe MUST be lower than the machine. Ensure drain hose has no bends/constrictions in it.

Electrical Connection

This machine has a molded U.K type plug BS1363.

Chemical Feeders Priming

Your Buffalo Glass Washer has a detergent pump and a rinse-aid pump for use with containers of NON-FOAMING liquid detergent.

1. Insert the hoses of the pumps in the correct chemical container (clear tube for
   detergent, blue tube for rinse aid).

2.  Ensure both of the hoses are at the bottom of the containers of the chemicals.

Note – The chemicals to be used should be suitable for Glass Washers. The detergent shall be the No Foam type, suitable for Glass Washing machines.

Note – We recommend that you use detergent and rinse aid from the same manufacturer. Jantex Glasswash detergent (CF978) & Jantex Glasswash rinse aid (CF979) are recommended.

Note – When the machine is installed from new or when the containers are allowed to run dry, the full priming takes place after 8-10 washing-rinsing cycles.

Detergent and Rinse Aid Pump Adjustment

1. Open the stainless steel front cover (remove 2x screws).
2. The pumps are ready for adjustment.

Detergent Pump

Detergent amount required is dependent on soil and water hardness. Dosage can be regulated by a screw above and on the right of the glass cover. The regulation can be from 0 lt/hour to 3.0 lt/hour. Adjust the quantity by regulating the dosing. Turning the adjustment screw clockwise, the flow is reduced (-), turning it counterclockwise the flow is increased (+). The detergent pump is factory set at the maximum (3.0 lt/hr).

Rinse Aid Pump

Rinse Aid amount required is dependent on water hardness. Dosage can be regulated by a screw above and on the right of the glass cover. The regulation can be from 0 lt/hour to 0.7 lt/hour. The rinse aid pump suctions 0.7 ml per rotation of the rotary mechanism. Adjust the quantity by regulating the dosing. Turning the adjustment screw clockwise, the flow is reduced (-), turning it counterclockwise the flow is increased (+).The rinse-aid pump is factory set at the maximum (0.7 lt/hr).
