Product Usage Instructions
Installation
- Cut power to the appliance by disconnecting the switch upstream from the device.
- Make sure that the cold water inlet cock (12) is closed and partially drain the contents of the storage tank unit using the relevant drain valve.
- Open any hot water tap of the domestic hot water system to let air into the storage tank unit.
- Connect the recirculation kit according to the diagram shown in Fig. 2.
- Preassemble the check valve (1) by joining the components (1a) and (1b) with loctite/teflon or similar material. Ensure that the check valve is assembled in the correct direction as indicated in the hydraulic diagram (Fig. 3).
- Pay attention to the connection of the pump. The water circulation direction of the pump should be the same as the arrow shown in Fig. 2.
- Position the recirculation probe (9) upstream of the pump as indicated in Fig. 2.
- Connect the circulator (5) and the recirculation probe (9) according to the wiring diagram (Fig. 4) and the cable path diagram (Fig. 5).
- Make sure to have closed the storage tank unit draining valve.
Operation
- Reopen the cold water inlet cock (12) to bring it to normal operation conditions.
- Re-power the appliance.
Note: To avoid stall conditions, if installing the recirculation kit with a thermostatic mixing valve inside the solar kit, ensure that the mixed water temperature is set higher than the DHW set temperature.

- N.B: Check valve (1) must be preassembled by joining the com-ponents (1a) and (1b) with loctite/teflon or material with similar characteristics and must be assembled in the correct direction, as indicated in the hydraulic diagram (Fig. 3).
- N.B: pay attention to the connection of the pump whose water circulation direction must be the same as the arrow shown in the Fig. 2.
- N.B: position the recirculation probe upstream of the pump as indicated in Fig. 2.
- Connect the circulator (5) as indicated in the wiring diagram (Fig. 4) and represented in the cable path diagram (Fig. 5). The circulator is controlled using the two relay kit to be configured as indicated in the appliance instruction booklet.
- Connect the recirculation probe (9) as indicated in the wiring diagram (Fig. 4) and represented in the cable path diagram (Fig. 5)
- Make sure to have closed the storage tank unit draining valve.
- Reopen the cold water inlet cock (12) to bring it to normal operation conditions.
- Re-power the appliance.
- To avoid stall conditions, in case of installation of the recirculation kit with thermostatic mixing valve inside the solar kit, make sure you have configured the mixed water temperature at a higher setting than the DHW set.
