3. In case of continuous operation, apply a 1-hour break every 4 hours of operation.
4. Never move the appliance when running.

CAUTION

Take utmost care to install and operate the appliance in strict accordance with this manual. In case of a mechanical failure, please first refer to the “Troubleshooting” section in this manual, and then call our call centre to request for authorized service if necessary. Always avoid unauthorized intervention in the appliance.

Use of Detergents and Rinse Aid in the Dishwasher

1. Remove the plug on the rear part of the appliance and connect the hose from the detergent dosing unit to the wash tank using a proper coupling.
2. Dirt level of dishes and detergent characteristics should be considered to assess water hardness and consumption in the dishwasher. User should never modify the detergent dosing rate set by authorized members of the detergent company.
3. If detergent dose supplied to the appliance is increased through unauthorized intervention, excess foam would be produced, causing the dishes look dirty and detergent-contaminated after washing, and also excessive detergent consumption would occur. On the contrary, reducing the detergent dose would cause inefficient washing, resulting in non-cleaned dishes.
4. Rinse Aid pump is automatically set according to rinse water consumption and water hardness. Thanks to this automatic setting, excessive rinse aid feed and excessive foam production in the washing system is avoided and hence poor rinsing performance and dirty-looking dishes contaminated by hazardous chemical agents are prevented.
5. Another harmful effect of excess rinse aid in the rinse water is the occurrence of a higher acidic effect resulting in abrasion of the rinsing line.
6. The detergent and rinse aid used should be health-friendly.
7. It is recommended to use non-effervescent detergents and rinse aids designed for dishwashers.

CLEAN-UP AND MAINTENANCE

Periodical Maintenance and Clean-up

Daily maintenance should be carried out by people informed about the safety instructions as following, after disconnecting power supply and water connections.

Daily Maintenance:

Daily maintenance should be carried by the user. In order to clean up the machine within the day following should be carried out periodically after the washing operation:

1. Wash and rinse arms should be disconnected and the scraps remaining in those arms should be removed away using pressure water, brush, fine wire etc. and reinstalled back to their places.
2. Scraps remaining in the washing tank should be removed and cleaned up. (Do not carry out washing operation without installing scrap filters)
3. If the period between two washing operations exceeds “5 Hours“ water outlet pipe should be disconnected and all of the water should be drained out fully.
4. Suction filter should be disconnected and cleaned up with plenty of water.
