1. The power of the dishwasher is relatively high. When using the dishwasher, power should be supplied separately. The capacity of the socket is 10A, 250V single-phase three hole socket, and it should be well grounded.

2. Dishwasher should be placed horizontally, away from heat sources such as LPG stoves, and don't let the sun shine directly on the dishwasher for a long time, so as to avoid fading, yellowing or falling off of the shell paint, which will affect the appearance.

3. In order to ensure the normal water inlet and outlet of the water inlet pipe and the water outlet pipe, put the water pipe as smoothly as possible to prevent bending or circuitous knotting, and do not press heavy objects on the hose.

4. When using the dishwasher, don't use hot water above 70 degrees Celsius to avoid deformation or damage of plastic and rubber parts. The hot water discharged after high-temperature cleaning still has a fairly high temperature, so please handle it carefully.
