Lithium Car Washer

Help you quickly understand the installation details

Installation of Accessories

The inlet filter nets must always be in place to filter out sand, lime, and other impurities as they will damage the pump valve. Before delivery, the product is equipped with filter nets at the inlet hose connector and one end of the water inlet hose.

Installation of Components

• Connect the multifunctional jet nozzle to the quick outlet connector on the device.
• Screw tightly the foam tank to the device. Pour detergent into the foam tank. The detergent can be used to rinse off the dirt.

Water Connection

Connect to a low-pressure water supply

The device can operate under the self-priming mode, which means it can be connected to a water container, etc. When drawing water from mains of undrinkable water, the backflow preventer is not required. When connecting to a low-pressure water supply for operating, please use an external filter to make sure impurities will not be sucked in. To meet these requirements, it is recommended to use the original water inlet components. Use the new hose parts that come with the device; the old hose parts are non-reusable. Make sure that the filter net is installed at the proper place of the inlet and that the inlet hose is connected to it tightly. Turn on the device and pull the trigger. Wait until the nozzle discharges a steady stream of water.

Connect to pressurized water supply

The maximum feed pressure and temperature of the inlet are 0.7MPa/7bar and 40°C respectively.

• Check whether the filter is installed inside the inlet hose and is not blocked.
• Connect the hose to the water tap using the quick connector and then open the water tap.
• Before connecting the hose to the device, let the water flow through the hose to prevent sand and dirt from entering the device.
• Turn off the water tap and connect the hose to the inlet using the quick connector.
