The CO-1.. pressure-boosting system type (Fig. 1a, Fig. 1b) can be connected directly or indirectly to the public water network using a break tank from the Wilo range or a break tank to be provided by the customer. The CO/T... pressure-boosting system type (Fig. 1c) is supplied with an integrated break tank and is therefore already prepared for indirect connection to the public water supply network.

NOTICE We recommend that the initial commissioning of the system is per- formed by the Wilo customer service department. • Contact your dealer, your nearest Wilo representative or the Wilo cus- tomer service department. NOTICE Automatic activation after power cut Depending on the process, the product is activated and deactivated us- ing separate controls.
Observe the respective manufacturer’s documentation for the compo- nent. 7.2.2 Operation with separate break With Wilo break tanks, the level-dependent low-water monitoring is performed via a float tank (inlet mode) switch (see example Fig. 9a, 9b). • Connect the float switch before commissioning in the control device.
If necessary, correct the pressure by filling with nitrogen. (PN 2 = pump switch-on pres- sure p minus 0.2 – 0.5 bar or value given in the table on the tank (Fig. 4) – Wilo cus- tomer service). If the pressure is too high, release nitrogen from the valve.
