Close the shut off valves or block the flow of water at the pool inlet and return
ports.
Disconnect the filtration system from the pool, drain the tank and hoses.
Place the handle on the central valve in position 7- ‘Winterize’ to relieve the
tension on the spring and internal valve components.
Store the filter system in a location protected from frost and severely cold
temperatures. In a garage or insulated storage shed is recommended.
Q
.
Important Do’s & Don’ts
DO’S:
Be aware and make note of the filter pressure when the sand is clean. Backwash
when you see an increase of 10 PSI on the pressure gauge.
Backwash long enough to clean the sand bed. Let the system backwash until the
water leaving the waste line is clear. Note that backwashing can remove 50 – 300
gal of water from your pool so pay attention. Also, be aware of local codes
regarding pool water disposal as some communities have rules or codes
regarding pool water drainage.
Protect bottom strainer while replacing or adding sand. Fill the tank with 8” – 12”
(about 1/8 of tank height) of water. Cover the water chamber to avoid getting sand
inside the riser pipe and laterals.
Start filter in Backwash mode for about 3 minutes and then for about 1 minute in
the rinse mode before initial startup or after adding new sand. By doing this you
can avoid blowing small particles and impurities from the new sand into your pool.
If some debris from new sand does go into your pool, vacuum it with the system in
purge mode, otherwise you may send it back to the pool.
DON’TS:
Move valve handle while the pump is running. It will damage the valve and
possibly other equipment as well.
Backwash excessively. Sand filters operate more efficiently during mid-cycle.
Some level of debris in the sand bed actually helps filtration and makes the filter
more effective. Too much backwashing will reduce efficiency.
Vacuum the pool in backwash mode. You can plug up the strainer at the bottom of
the filter which will result in inefficient operation. Plus you may have to remove all
of the sand to get it unclogged.
Let filtration system run dry (without water)! If your pump runs dry too long
non-warranty damage to the pump may occur. Damage to the pump caused by
dry running is NOT covered by the warranty.
