Adjusting The Balance - Astralpool VALS Manuel D'installation Et D'entretien

ADJUSTING THE BALANCE

For optimum performance, the VALS should be well balanced in the deepest part of the pool. As a result of its floating capacity, the hose tends
to lift the VALS, particularly in deep water.
6. MAINTENANCE OF THE VALS
1. During the winter season when the pool is not in use, the apparatus and the hoses should be fully cleaned with clean water. Leave to dry and
keep in a dry, frost-free place. The lengths of hose should be dismantled and kept stretched out.
2. During the bathing season, we recommend you to leave the VALS in the pool. If you wish to remove it while bathing, dismantle the hose, but
do not roll it or leave it exposed to the sun.
3. Check the wear of the accessories from time to time. The flexible base, the mat, membrane and the deflectors are essential parts.
4. UV sunrays, water and chemical products used for water treatment of the pool may damage the condition of the VALS. To lengthen the life
span of the VALS and the hoses:
•
Check that the pH is constantly at the level recommended by your dealer. A low or high pH will damage the majority of plastic and rubber
elements and will seriously damage the VALS.
•
Remove the cleaner from the pool before performing chemical shock treatment, and do not install again until at least 8 hours later.
Note: The severe operation conditions of a cleaner (chemical products, UV rays, etc.) may discolour the cleaner in the long term, even
under normal operation. However, this will not affect its cleaning capacity.
5. Water below than 20º may limit the efficiency of automatic pool cleaners.
MAINTENANCE OF THE SUCTION MECHANISM
The VALS is equipped with a MEMBRANE to quickly move the cleaner and suction the large majority of waste usually found in a swimming
pool.
This operation system allows waste to freely pass through, which in some cases, could obstruct the MEMBRANE, in which case it is necessary
to remove the debris blocking it.
CHANGING AND REPLACING THE MEMBRANE
TURN OFF THE PUMP AND DISCONNECT THE POOL CLEANER FROM THE HOSE
1. Unscrew the four screws from the bottom cover of the pool cleaner.
ATTENTION: Carefully unscrew the screw that attaches the cover and the rubber base, from
the back.
2. Lightly unscrew the connection tube on the pool cleaner
3. Extract the bottom cover of the pool cleaner together with the base, the membrane and the
transparent tube via the bottom of the pool cleaner.
4. Separate the membrane from the transparent tube.
5. Give the membrane a hard tug via the part underneath the mat, until it comes away and then
remove it from the cover that it was attached to.
6. Replace the membrane with a new one as shown in the diagram.
7. Re-insert the membrane into the transparent tube with the flange, attach the membrane cover
and insert the unit into the pool cleaner.
8. Screw in the connection tube and the 4 screws of the membrane cover.
9. Install the VALS and start-up the pump.
