1.1. Controller
The controller unit can be installed indoor and outdoor. Do not expose the controller to direct sun light or heat (powerful lamp, radia-
tor). Be sure there is enough air circulation. Keep all sides of the unit free for at least 10cm.
1.2. Pump
The pump must be installed in a horizontal position. The pump must rest firmly on a flat and even surface. Install the intake line to the
pump's inlet (1) (see fig.). Make sure the pump can evacuate air from the outlet (2). At best, install the pump below the water level (3).
The pump may be installed inside (4) as well as outside (dry) of the water (5). If operated outside, check for sufficient air circulation. Do
not expose the pump to direct sunlight. Install the pump as close as possible to the location of water withdrawal, i. e. the intake line
should be as short as possible. If the pump was operated above the water level (6) install a check valve to the pump's inlet (7). In this
case, the intake line of the pump must be filled with water. This kind of installation exposes the pump to dry run damages if the check
valve doesn't work correctly. Damages resulting from running dry are not covered by warranty.
1.3. Suction side (pump inlet)
If there is not enough water, due to the resistance of the intake line the pump needs a lot of power and the electronics will heat up in
the long run. The electronic circuit protects itself by powering down. If the flow rate of the pump decreases within a couple of hours or
days, the reason might be the too high resistance of the intake line, especially on warm days.
Try to enlarge the pipe diameter after the pump to a sufficient size for more pump capacity and and lower energy consumption.
It is not allowed to let the pump run dry. It will lead to irreparable damage to the shaft and silicium carbide bearings. Especially when
the pump is mounted above the water surface level (with a check valve) you have to be very careful about this. When used in dirty
water the use of a (previously described) pre-filter is necessary. The use of flexible fittings or unions is recommended for easy dismant-
ling for cleaning and/or maintenance.
