4. SCOPE OF DELIVERY
The scope of the delivery of this product includes :
a pump with connection cable, a connection, a sus-
pension rope of 3 meters, a seal with non-return
valve and instructions for use.
Please verify that the scope of delivery is complete.
Depending on the purpose of the application, addi-
tional accessories may be necessary (please refer to
the chapters titled "Installation" and "How to order
spare parts").
If possible, keep the packing until the warranty peri-
od has expired. Please dispose of the packing mate-
rials in an environmental-friendly manner.

being
All connection lines have to be perfectly tight since
leaking lines may affect the performance of the
CDW-400
pump and cause considerable damage. If required,
please use a suitable sealant to make the installation

airtight.

When tightening threaded connections, please do
not apply excessive force which may cause damage.

When laying the connection pipes, you should

make sure that the pump is not exposed to any

connection lines must not contain any kinks or an
adverse slope.

5.2. INSTALLATION OF THE PRESSURE LINE
5
The pressure line conveys the liquids to be discharged
from the pump to the point of withdrawal. To avoid
10
dynamic flow losses, one should use a pressure line
having at least the same diameter as the pressure
H05-RNF
port (1) of the pump.

1. Screw the connection elbow (9) into the pump
242 x 157 x 359
2. Fix a hose to the combination nipple.
The combination nipple can be trimmed to suit the
selected hose connection. Use the largest possible
hose diameter.
5.3. STATIONARY INSTALLATION
If the unit is used in a stationary installation, rigid pipes
have proven to be the ideal choice for the pressure
lines. In this type of installation, we recommend that
you incorporate a check valve (non-return valve) in
the pressure line immediately following the pump
outlet so that no liquid will flow back after the pump
cuts out. To facilitate maintenance work, we also
recommend the installation of a stop cock valve
downstream of the pump and check valve. This
arrangement is beneficial in that closing the stop
cock will prevent the pressure line from running dry
after the disassembly of the pump.
During the entire process of installation, the
device must not be connected to the
electrical mains.
The pump and the entire connection
system have to be protected from frost.
