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-ventilated 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. Perform installation so that
leaking water cannot drip onto the control module. To do this, align the
upper gate valve laterally, 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.
• If heat insulation work is necessary, only the pump housing may be in-
sulated. The pump motor, module and the condensate- drain openings
must remain uncovered.
Turn motor head
If the installation position of the module is changed, the
motor housing has to be turned as follows:
