7 Installation
The unit may not be installed in areas where there is a danger of
!
explosion or used to pump flammable liquids.
Figure 7a:
Only install in dry, frost-proof rooms in one of the permitted mounting positions.
Figure 7b:
We recommend that you use type WD-A thermal insulation shells, available
from the manufacturer, when you thermally insulate the pump. When using
other materials, leave the motor housing uninsulated; otherwise, the electronics
may overheat and the pump may switch off.
Screw connections for installing the pump in the system are not included in the
scope of delivery, but they may be ordered as accessories from the manufac-
turer.
Use new O-rings (included in the scope of delivery) when installing the pump.
The customer must take appropriate isolation measures and provide appropri-
ate acoustic insulation to reduce possible noise transfer.

7.2 Getting started
CAUTION
Before starting, the system must be:
-
Filled.
-
Rinsed thoroughly to prevent foreign objects and impurities from
blocking the pump.
-
Completely bled.
-
Audible flow noises indicate that there is still air in the pump.
Bleeding is sped up by repeatedly switching the pump on and off
in the highest power level.
After bleeding is completed, the pump should be set to the power required for
the actual system using the continuously adjustable power selection switch

The unit may only be connected by an authorized electrician.
The pump must be filled before the electrical connection is made;
if not, the bearings will be destroyed by dry operation. The pumps
do not require a separate motor circuit breaker. The connection
must be made as shown in figure 7.1.
The pump may not be run dry, as this can destroy the bearings in
a very short time.
