Installation
DANGER: Before starting work, make sure that the
pump is disconnected from the power supply.
Installation site
• Provide a weatherproof, frost-free, dust-free, and well-
ventilated room for the installation.
Choose an easily accessible installation site.
• Prepare the installation site so that the pump can be
installed without being subjected to mechanical stresses.
If necessary, support or secure piping on both sides of the
pump.
NOTICE: Provide shut-off devices upstream and down-
stream of the pump to facilitate potential future pump
replacement. Perform the installation in a way that prevents
leaking water from dripping onto the control module. To do
this, align the upper gate valve laterally if necessary.
• Complete all welding and soldering work near the pump
prior to the installation of the pump.
CAUTION: Dirt can cause the pump to fail. Flush the
pipe system before installation.
• Choose the correct installation position, with the pump
motor in a horizontal position, from only the positions
shown in (Fig. 3). Direction arrows on the pump housing
indicate the direction of flow.
• If heat insulation work is necessary, only the pump housing
may be insulated. The pump motor, module, and
condensate drainage openings must remain uncovered.
