Caution Caution Caution Caution Caution Rotex 70/10/20 14 5.5.2.2 Rotex D Themotor is protected by temperature switches installed in the motor winding which trip if the maximum permissible winding temperature is reached and restart automatically after the motor has cooled down. The external protection equipment should always have three poles and an interlocking device in order to ensure complete separation from themains; this equipment will also prevent the unit from running on two phases only. 5.5.3 Checking the Direction of Rotation Rotex E The direction of rotation of Rotex E need not be checked,...

Caution Caution Caution Caution Caution Caution Caution Rotex 70/10/20 15 6.1.2 Rotex 10/20 Rotex 10/20 pumps are suitable for pumping condensate with a temperature of up to 90 .C from unpressurised tanks. The tanks should be equipped with vent pipes having twice or at least the same nominal diameter as the inlet pipes. When pumping liquids with a temperature above 70 .C, a minimum head of 8metres (pressure gauge reading)must be ensured to avoid cavitation and thus premature wear on the bearings. Whenthe pump is used for pumping condensate, the switch-off level should be at least 400 mm. The...
