Connection of the thermal winding cover :
- Control loop : T1 and T2 must be connected in a switching device in such a way, that the following function
is guaranteed: When the temperature sensors respond, the pump is switched off until the tempera-ture has
dropped again. Now the pump is switched on again.
- Clipping circuit : T2 and T3 must be connected in a switching device in such a way, that the following
function is guaranteed: When the temperature sensors respond, (failure of the control loop), the pump is
switched off and can be restarted by hand solely. The pump may only be restarted after an er-ror analysis
has been conducted and the cause of malfunction has been eliminated.

These pumps are not to be mounted in dry installation, since a minimum
water level up to the bottom edge of the motor housing is prescribed by
the guideline on protection against explosion.
Installation with supporting ring :
- Mount supporting ring to intake flange of the pump and install pump. Ensure stability of the pump.
- Optionally connect pressure side by means of flange DN 50 or thread (The pump is equipped with a female
thread G2 and a flange DN 50).
- If a hose is to be laid on the pressure side, kinks are to be avoided.
- Avoid kinks during the laying of the supply cable. Lay supply cable without tensile loading and without
causing chafe marks.
Installation for shaft fitting :
- Position pipe clamp on inner rim of the shaft and loosely fix it with two screws.
- Sound out position of guide pipe frame for coupling pedestal, adjust coupling pedestal on shaft bottom and
mount it with the heavy-duty dowels which are included in the delivery.
