Application

The pressure washers can be used to remove dust, deposits and dirt from the fins of domestic and commercial air conditioners and to wash drain pans, housings and unit covers.

Connection

1. 01With the pressure washer switched off and disconnected from the power supply, check the condition of the hoses, connections and C28T power cable. Check the inlet filter, spray gun head and the fastening of screws and nuts.
2. 02Check the oil level in the oil level sight glass - see the ‘MAINTENANCE’ section.
3. 03Connect the high-pressure hose to the pressure washer water outlet, and connect its other end to the spray gun using the quick-release coupling. A click indicates that the quick-release coupling has locked; do not fit the nozzle yet.
4. 04Connect the inlet hose to the pressure washer water inlet and check that the seal is present. When drawing water from a tank, immerse the end of the hose with the inlet filter in the water; the water surface must not be lower than the pressure washer.
5. 05When supplying water from a tap, connect the free end of the inlet hose to the tap and turn on the water supply.
6. 06Connect the C28T to an earthed 230 V socket or insert an 18 V AEG/RIDGID battery compatible with the device interface into the C28B. Only start the pressure washer when bleeding air from it.

Operating instructions

Bleeding air

1. 01Press and hold the spray gun trigger without a nozzle fitted, then switch on the pressure washer at the lowest pressure: C28T - pressure adjustment dial at minimum, C28B - switch position I.
2. 02When drawing water from a tank, once water begins to flow, continue operating with the trigger held down for 1 min. When supplied from a tap, hold the trigger down until water flows in a steady stream.

Cleaning

1. 01Switch off the pressure washer and disconnect the power supply. If using a tap, turn off the water supply; press the spray gun trigger to release the pressure in the high-pressure hose. Fit the original nozzle and an extension suitable for the job.
2. 02If using the 1:3 dispenser, fit it at the spray gun and place the suction tube in the product container.
3. 03If using a tap, turn on the water supply. Connect the power supply and switch on the pressure washer. On the C28T, set the pressure using the pressure adjustment dial; on the C28B, select the level using the switch.
4. 04Start at low pressure and test the spray on an inconspicuous area of the surface being cleaned. Adjust the pressure and distance so that the fins are not deformed; turn the rotary nozzle left or right to set a straight or fan spray.

Finishing work

1. 01Switch off the pressure washer and disconnect the power supply.
2. 02If using a tap, turn off the water supply. Press the spray gun trigger to release the pressure in the high-pressure hose.
3. 03Clean the housing and inlet filter as described in the ‘MAINTENANCE’ section.

Water dripping from the drain opening in the pump body during operation is normal and does not affect the operation of the pressure washer.

Maintenance

General recommendations

• ■After use, clean the exterior with a soft brush or cloth. Do not use water, alcohol, petrol, solvents, corrosive substances, strong detergents or polishes. Do not allow chemicals to enter the pressure washer.
• ■Remove dirt, particularly from the ventilation openings.
• ■To clean the inlet filter, remove it from the inlet hose, remove any dirt and refit it before operation. Do not use the pressure washer without the inlet filter. Dirt can block the pump, reduce pressure or stop the water flow.
• ■After maintenance, check the condition of the device and accessories, then connect the pressure washer and check its operation as described in the ‘CONNECTION’ and ‘OPERATING INSTRUCTIONS’ sections.

Oil

The correct oil level reaches the centre of the oil level sight glass. Use 15W-40 engine oil of API CD grade.

Have the service centre change the oil every 200 h of operation, including the first oil change after purchasing the pressure washer - submit a service request at wipcool.pl/serwis.

Seals

If water leaks from the pump head after prolonged use, stop using the device. Have it repaired by the service centre - submit a service request at wipcool.pl/serwis.

Troubleshooting

Before checking connections or removing the extension and nozzle, carry out the steps described in ‘Finishing work’.

Waste electrical and electronic equipment

Under applicable regulations on waste electrical and electronic equipment, products marked with the separate collection symbol must not be disposed of with other municipal waste. Because they contain harmful substances, electronic products that are not separately sorted may be hazardous to the environment and human health. Proper separate collection of waste electrical and electronic equipment prevents adverse effects on the environment.

By taking used equipment to a collection point, the user contributes to its reuse, recycling and recovery.

Recycling - one method of protecting the environment. The process of recovering substances from waste that can be reused as raw materials.

Waste recovery - the use of waste that has lost its useful value, such as plastics, paper and cardboard, as secondary raw materials (also commonly understood to mean its destruction).

Information on the collection system for waste electrical and electronic equipment

• ■Waste electrical and electronic equipment must not be disposed of with other waste.
• ■The collection of incomplete electrical and electronic equipment and parts from waste equipment is prohibited.
• ■A distributor delivering equipment intended for households to a purchaser is required to collect household waste equipment free of charge at the place of delivery, provided that the waste equipment is of the same type and performs the same function as the equipment delivered.
• ■The user may hand over waste equipment to a waste equipment collector, a treatment facility or a municipal waste collector operating in the municipality.
• ■Information about collection points is available on the public information bulletin (BIP) websites of regional, city and municipal authorities.

Service and documents

Before submitting a service request, prepare:

• ■Model - shown on the device nameplate and on the invoice.
