• DN80
• Install appropriate flat gaskets between pump and counter flanges.
• Tighten the flange bolts crosswise in two steps to the prescribed tightening
torque (see Table 7.1.2).
• Step 1: 0.5 x permissible tightening torque
• Step 2: 1.0 x permissible tightening torque
• Check the flange connections for leaks.

7.1.3 Insulation of the pump in cooling/air-conditioning systems

• For applications in cooling and air-conditioning systems, commercially-availa-
ble diffusion-proof thermal insulation materials must be used.
CAUTION! Risk of damage to property!
If the diffusion-proof insulation is fitted at the site, the pump housing may
only be insulated up to the motor flange. The condensate drain holes must
remain unobstructed to ensure that condensate that develops in the motor
can drain without problems (Fig. 6). Condensate that accumulates in the
motor can cause an electrical defect.

7.2 Electrical connection

DANGER! Risk of fatal injury!
Improper electrical connections pose a risk of fatal injury due to electric
shock.
• Only allow the electrical connection to be made by an electrician approved
by the local power supply company and in accordance with the local regula-
tions in force.
• Before working on the pump, all poles of the power supply must be discon-
nected. Work on the module may only be started once 5 minutes have
passed, due to the dangerous residual contact voltage.
• Check to ensure that all connections (including potential-free contacts) are
voltage-free.
• If the control module is damaged, the pump must not be put into operation.
• If setting and operating elements are improperly removed, there is a danger
of electric shock if interior electrical components are touched.
• Connecting the pump to an uninterrupted power supply (UPS or IT power
supply) is prohibited
