Help you quickly understand the
installation details
The inlet filter nets must always be in place to filter
out sand, lime, and other impurities in that they will
damage the pump valve.
Installation of Accessories
Before delivery, the product is equipped with filter
nets at the inlet hose connector and one end of the
water inlet hose.
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.
Connect to pressurized water supply
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.
Connect the multifunctional jet nozzle to the quick
outlet connector on the device.
Installation of Components
Screw tightly the foam tank to the device.
Pour detergent into the foam tank. The detergent can
be used to rinse off the dirt.
Connect to a low-pressure water supply
Water Connection
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.
