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 tempera-
ture 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-prim-
ing 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 recom-
mended 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.
