7.2 Preparation before washing and rinsing
Before operation please check the following

• Open the door
• Make sure the drain pipe and sieve net in the right place
  *Close the door

Danger! Must use two hands to close the door .
Each program selection key has indicator for the instructions of the machine operating status. After press the program selection keys, clean water flowing through the rinse  heater is repeatedly heated to the washing tank.
The time of washing preparation depends on the water temperature and heating ability of rinsing heater. If filling water is cold, heating time is 30 minutes.

7.3 Using of cleaning solvent
If you do not install the detergent dispenser, you can add the detergent manually. The first time, add 40g, then every 5 washing cycle ,add 30 and keep the detergent  concentrations at 2g / l.
If you add the powder detergent, and detergent must uniformly distributed in the washing tank so that the powder can melt into water avoid fading of the stainless steel

7.4 Add washing detergent automatically
The general machine did not have detergent drier distribution device, which need customer to buy or detergent manufacturers to provide. The customer also can purchase the machine with the detergent drier distribution device.
Distributor will automatically add the appropriate amount of detergent according to the amount of water and its dirty degrees (Built-in distributor parameter setting can be set reference B2, adjust the parameters of detergent and drier to be the best state). We recommend to use the detergent ph value great than 7 and detergent drier ph value between 2 and 7.

7.5 Washing and rinsing operation
The washing utensils should be inserted in the washing basket and special classification is no need but the following points be noted that:
① All hollow containers must be inverted, otherwise it is easy to reserve water affecting the drying effect.
When the basket contain small items such as knife and fork spoon , insert the handle down , please do not stack or piled up the small items together and do not place  excessive cutlery in the same basket .
Stacking dishes in the washing basket is not allowed otherwise it would worsen the washing effect and properly placing the utensil will make washing effect more better, placing the washing basket on the dishwasher bracket.
④ When the food in dishes becomes dry, must be soaked until soft rear can clean, otherwise it will affect the washing effect.

11.1 General description of the dishwasher
11.1.1 Loading
500 * 500 square washing basket with washing capacity of 30 baskets / h.
11.1.2 Cleaning guidelines
Machine wash and rinse cycle
Washing basket fixed, the rotation of the upper and lower wash arm is promoted by high-pressure wash water.
The advantage of this approach is that the washing arm can clean the dishwasher from all angles and there is no dead angels ensuring the quality of the washing.
The rinsing procedure follows after washing procedure, rinse arm spraying 50-70 Celsius high temperature water ( temperature controlled at 65 degrees Celsius when washing cups ), a cycle of rinse water as wash water, thus ensuring the clearance of washing water.

11.1.3 Detergent dosage
The detergent dispenser is purchased by user, not standard machine configuration.
Under normal circumstances detergent amount in the water tank is 2ml / L. according to different water and oil, detergent amount may change between 1ml/L and 5ml / L.

11.1.4 Drier dosage
This machine must use liquid drier. Drier is added by standard drier distributor in every rinsing process.
Correct drier dose should wash the dishes leaving a thin layer of water film.

• If the dose amount is too large, foam or water streaks will appear on the dishes.
• If the dose is too small, there will be residual water droplets on the dishes.
  About the drier’s amount, please reader instructions.
  11.1.5 The noise level
  The noise level is about 61dB when operate the equipment.
