It is common knowledge that fishes and in particular most invertebrates benefit from strong, irregular water
movement in a marine aquarium.
parts and are efficient in operation.
Operating instructions
The HLP pumps come with a standard 3 stage selector switch. The interval control is connected to
the pump through a control cable. A potentiometer with an on/off function will start/stop the interval mode
and allows setting of the interval time span.
Standard pump operation
Select required performance at the pump 3 stage selector.

Interval operation
First, the pump is set to the lowest power setting (level 1 or 2). Then the interval control is switched on by
turning the regulator in a clockwise direction (yellow/green LED lights up). The interval time can be set to
between 8 seconds and 20 minutes. If the green LED lights up, the level selected at the pump is active. If
the yellow LED lights up, level 3 is active.
If you turn the regulator to "programme mode" (the blue LED lights up), 50 pre-programmed interval times
of between 5 seconds and 15 minutes are called up. After these 50 cycles have been completed the process
is repeated.
HLP interval pumps are available in 5 sizes, from 4500 litre/h to 9000 litre/h
Please note
The water flow of the pump is determined by the water head as well as the flow resistance in the piping
system. Non-return valves, long pipes and a large number of elbows can reduce the water flow considerably.
Maintenance
The HLP pumps are basically maintenance free.
When used in marine aquaria a build-up of lime scale is possible. It is advisable to clean the pump from time
to time (every 6 to 12 month) with a commercially available lime scale remover. Do not dismantle the pump
for this purpose.
Plug the suction side of the pump and fill the housing with lime scale remover.
Afterwards flush the pump with tap water.
