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 switch 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.

3.2 SPECIFIC VALVE MAINTENANCE

The internal elements of the valve require regular maintenance in accordance with the following
specifications:
- Perform all operations with the pump off and with the input and output valves to the filter and the
multiport valve closed.
- Remove the actuator as described in point 5.4 of the manual.
- Remove the remaining 3 screws holding the valve cover in place.
- Remove the cover to allow access to the internal distributor.
- Lift the distributor and clean the area around the distributor seal, clearing away any residue that may
hinder rotation.
- At least once a year, grease the O-rings on the distributor shaft to facilitate the movement of the
distributor. The grease used to lubricate the O-rings should be TURMSILON GL320 NLGI 1-2 (LUBCON).
The manufacturer supplies the specified grease together with the valve. The use of unauthorised grease
can irreversibly damage some components of the valve and therefore cause the guarantee to be invalid.
- Reassemble the distributor. Mount the cover with the previously assembled gasket and fix it with the 3
screws and the 3 nuts, with the proper torque to ensure the seal.
- Mount the hood on the distributor shaft, matching the triangle mark with the notch (8) of the bell. Fit
the pin (6)
- Fit the cam-ratchet (5), according to Figure 7.
- Fasten the screw (3) to the end and loosen it a quarter of a turn.
- Mount the actuator and fix it with the remaining screws and nuts.

3.3 GUARANTEES.

The valves leave the factory in a fully tested condition, which enables us to guarantee operation. The
guarantee will be effective provided that the installation and maintenance has been correctly carried
out and this requires that the actual installation operation be performed by a person with the necessary
qualifications for this type of work. A specific sheet with the valve guarantees is attached to the manual.
