Storz coupling mounted.
1. Use a shackle to attach the lifting equipment to the attachment point of the pump.
2. Lift the pump and lower it at the intended location (chamber, pit).
3. Place the pump on a solid bearing surface. CAUTION! Sinking must be prevented!
4. Lay the pressure hose and fasten it to a certain point (e.g. drainage).
DANGER! Separation or movement of the pressure hose can lead to (serious) in-
juries! Securely attach the pressure hose to the outlet.
5. Lay the power supply cable properly. CAUTION! Do not damage the power supply
cable!
▶ The pump is installed, the qualified electrician can make the electrical connection.
NOTICE
Delivery problems due to water level being too low
If the level of the fluid is lowered too much, the volume flow can be interrupted. Air
cushions can also form in the hydraulics, which can lead to inadmissible operational
behaviour. The minimum permissible water level must reach the upper edge of the
hydraulics housing!
In dry well installation, the operating space is divided into the collecting space and the
machine room. In the collecting space, the fluid flows and is collected; the pump tech-
nology is installed in the machine room. The pump is installed in the machine room and
connected to the pipe system on the suction and pressure side. Observe the following
points for installation:
▪ The suction- and pressure-side pipe system must be self-supporting. The pump must
not support the pipe system.
▪ Connect the pump to the pipe system ensuring that it is free of stress and vibrations.
The use of elastic connection pieces (compensators) is recommended.
▪ The pump is not self-priming, in other words, the fluid must flow in either automatically
or with supply pressure. The minimum level in the collecting space must be at the same
height as the upper edge of the hydraulics housing!
▪ Max. ambient temperature: 40 °C (104 °F)
