Constant differential pressure (∆p-c):
The differential-pressure setpoint H is kept constant over
the permitted volume flow range at the set differential-pres-
sure setpoint up to the maximum pump curve (Fig. 2b).

4 Installation and electrical connection

4.1 Installation
DANGER: Before starting work, make sure that the
pump has been disconnected from the power supply.

Installation site

• Provide a weatherproof, frost-free, dust-free and well-venti-
lated room for the installation.
Choose an installation site that is easily accessible.
• Prepare the installation site so that the pump can be
installed without being exposed to mechanical stresses. If
need be, support or secure piping on both side of the pump.
NOTE: Provide check valves upstream and downstream of
the pump to facilitate a possible pump replacement. Per-
form installation so that leaking water cannot drip onto the
control module. To do this, align the upper gate valve later-
ally, if need be.
• Complete all welding and soldering work near the pump
prior to the installation of the pump.
CAUTION: Dirt can cause pump failure. Flush the pipe
system before installation.
• Choose the correct installation position with horizontal
pump motor - only as shown in (Fig. 3). Direction arrows on
the pump housing and, where applicable, the insulation
shell indicate the direction of flow.
