Page 38: Function
4.6.2 Description Standard and special versions In the standard version, the Wilo pressure-boosting systems from the ISAR MODH1 series consist of non-self-priming multistage horizontal high-pressure multistage centrifugal pumps. The pressure-boosting systems from the ISAR MODV1 series consist of non-self-priming multistage vertical high-pressure centrifugal pumps without an in- tegrated frequency converter. - Page 39 When using a Wilo break tank (Fig. 11a), the scope of delivery includes a float switch (Fig. 11b – It. 52). For existing on-site tanks, you will find various signal transmitters in the Wilo range that can be retrofitted (e.g. float switch WA65 or low-water electrodes with a level re- lay).

Page 40: Transportation And Storage
The pressure-boosting system is fixed onto a pallet (Fig. 13a, 13b – It. 55, 56), de- livered on transport boards or in a crate and is foil-wrapped (Fig. 13a, 13b – It. 59) to protect it against moisture and dust. Transport and storage instructions applied to the packaging must be observed. WILO SE 2021-04... -

3. Take suitable measures to prevent heat transmission through the connection pipes. NOTICE PE tanks from the Wilo range are only designed to accommodate clean water. The maximum temperature of the water must not exceed 50 °C (including tank docu- mentation!). - Page 47 Flexible connection pipes are subject to wear in operation. Regular checks for leak- ages or other defects are necessary (see recommendations of DIN 1988). The flexible connection pipes in the Wilo range consist of a high-quality stainless steel corrugated hose with stainless steel braiding. In the case of pipes with threaded con- nections, use for stress-free installation of the pressure-boosting system and in the event of slight pipe displacement (Fig.
