2.4 fUSE .

The valve's electronics board incorporates a safety fuse to prevent any damage being caused to the J10
connection (terminals 4 and 5).
As stated in the previous point, incorrect connections or other connected components which increase
power consumption at the connection between the solenoid valve of the pump contactor and the valve
may result in operational faults.
A fuse therefore prevents the consumption through this conductor exceeding 0.4 A, thus preventing such
faults. In the event that the fuse fails, check the electrical installation to ensure that it matches the electrical
diagram before replacing the fuse with a new one of the same specifications.

2.5 DRAINAGE SAfETY.

The valve comes ready to be installed in an electrovalve in the drainage circuit. Its use is recommended in
order to avoid water loss in case there is no electrical connection and the valve ends up in a position that
could lead to the pool emptying. The electrovalve used should have as low a pump pressure orifice as
possible, maximum 40 - 50 kPa (0.4 - 0.5 bar). The voltage of the solenoid should be 24 Vac (See APPENDIX
1 - Fig. 9).
3. MAINTENANCE AND GUARANTEES.

3.1 HYDRAULIC INSTALLATION MAINTENANCE

Regular maintenance needs to be carried out on all components of the pool's hydraulic circuit in order
to ensure optimum operation of the installation and thereby prevent damage to the valve or any other
components.
The maintenance operations that may have a direct impact on the operation of the multiport valve are
listed below:
- Be sure to empty and wash the skimmer baskets on a regular basis to keep them clear of leaves and any
other waste. Baskets should be replaced if they are damaged.
- Be sure to empty the basket of the pump pre-filter, clearing away leaves and any other waste. Replace
the basket in the event of damage.
- Regulate the suction and return valves by adjusting the valve's pressure sensor before setting the filter
wash pressure. This operation should be repeated whenever a component is changed or added to the
installation or whenever the regulation setting of the valves is changed.
