** Must not freeze. To avoid condensation the fluid temperature must always
be higher than the ambient temperature. For Domestic Hot Water
applications the max fluid temperature is 85°C
*** Performance of the pump will noticeably change when pumping
water/glycol mixtures with concentrations higher than 20%.
5. Characteristic Curves (see figure 2a + 2b +2c)
6. Installation Advice
The installation of a stop valve upstream and downstream of the pump
is recommended so the pump can be replaced at a later time without
the need to completely drain the system.
7. Installation
Figure 3: Only install in dry, frost-proof rooms in one of the permitted
fitting positions.
