Make sure that the direction of the inlet and outlet pipes of the pump is installed
correctly, the inlet valve of the pump is vertically downward, and the outlet valve is
upward, which cannot be reversed. Refer to Fig. 1, Exported diagram of the pump base,
to disassemble and install. If any part of the pump is lost, the pump cannot not work
normally.
To keep the pump function correctly, make sure the inlet and outlet valve are
clean.

To ensure dosing function accurately, a complete set of pump which provide by
Emaux (foot filter, injection valve and transparent tubes) must be used. The foot filter
must be placed 5-10cm over the bottom of chemical container so to avoid being
blocked by chemical precipitate and damage the pump.
If possible, install a safety valve at the outlet to avoid damage to the pump when
the pump is blocked.
Suction tube and priming valve Tube connection: make sure the tube is well
connected with pipe holder so to prevent liquid leakage and gas leakage (which will
cause idling). Check the condition of tubes regularly. If the tube (especially the
connection) is aging, replace a new tube immediately.
Manual gas release: when gas is inside suction tube or opaque deliver y tube which
will affect the pumping performance. To release gas inside tubes:
Prepare a small container to contain leaking.
Connect the transparent tube for priming to priming valve connector (on the right
hand side of dosing head), and the other end to the container.
Open the priming valve by turning the priming valve knob in anticlockwise
direction, run the pump until gas in tubes are released with liquid leaking.
Close the valve by turning the priming valve knob in clockwise.
