Installation and operating instructions
37
English
• 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 conden-
sate drainage openings must remain uncovered.
Turning the motor head
If the installation position of the module is changed, the
motor housing must be turned as follows:
• Loosen the interior hexagonal head screws.
• Turn the motor housing, including the control module.
NOTICE:
In general, turn the motor head before the system
is filled. When turning the motor head in a system that has
already been filled, do not pull the motor head out of the
pump housing. Turn the motor head with a small amount of
pressure on the motor unit so that no water can come out of
the pump.
