7.1.
Fill in the pump housing
Before you use the pump for the first time, the pump housing (8) has to be fully
filled with water. Therefore, fill up the pump housing (8) via the integrated pre-
filter according to the illustrations below.
1.
Open the filter lid by turning in counterclock-
wise rotation. You can take something like a
screwdriver for help.
2. Put a min. 20 cm long bar in the middle of the
filter and push it carefully down, to open the
check valve. Fill in the water until the top,
once the valve is pressed.
3. Take out the bar and screw the filter lid back
by rotating clockwise. Please make sure, that
the seal isn´t dirty and properly lost in the fil-
ter.
It is highly recommended to vent the suction line (2) as well, i.e. to fill it with wa-
ter. It is true that the electrical pumps of the T.I.P. HWW series are self-priming
and can be put into operation by filling only the pump housing with water. In this
case, however, the pump will require some time before it will have sucked in the
liquid to be pumped and proceed to the actual discharging function. In addition,
this way of proceeding may require the pump to be filled several times. This de-
pends on the length and diameter of the suction line. After filling, please open
any shutting device (7) in the pressure line, for instance a water tap, to enable
the air to escape during sucking in. Plug the mains plug into an easily accessible
230V AC socket, the green "Power" indicator must now light up.
