Switch off pump. 2 . Depress lever on multiport valve and turn to backwash position. 3 . Switch on pump and run for about 3 minutes or until the dirty water passing through the sight glass becomes clear. 4 . Switch off pump. 5 . Move lever on multiport valve to rinse position. 6 . Switch on pump and run for 30 seconds. 7 . Switch off pump. 8 . Return lever on multiport valve to filter position and recommence filtration. Test   and   dose   your   pool   regularly   -   preferably   each   day.   The   efficiency   of   your   sanitiser,   e.g.   Chlorine,   reduces   as   the pH   level   increases.   For   optimum   results   maintain   a   pH   reading   of   7.2   -   7.4,   a   Chlorine   reading   of   1.5   -   3.0   ppm,   or   a Bromine reading of 3.0 - 4.0 ppm. To   shock   dose   correctly   you   should   raise   the   chlorine   level   in   the   water   to   more   than   6.0   ppm   with   unstabilised chlorine. Ensure   your   solar   cover   is   kept   on   the   pool   when   not   in   use   to   minimise   heat   loss   and   to   maximise   chemical efficiency. Always   use   a   solar   cover   roller.   This   not   only   prevents   dirt   from   being   dragged   into   the   pool   but   safeguards   the cover guarantee. When the cover is on the roller protect it from the sun with a solar cover protector sheet. Change the sand in your filter at least every 3 years to maintain filter efficiency. Check that your pool electrics are safe and comply with current legislation. Return to Contents --------------------------------------------------------------------------------   POOL OPENING PROCEDURE  1 . Remove Winter Debris Cover and pack carefully away for the season. 2 . Replace skimmer flaps and baskets, steps and check pump basket "0" ring. 3 . Clean filter sand with filter cleaner, leave overnight and backwash the following day. 4 . Put filter in backwash position and dump as much of last year's water as possible. Top up with fresh water. 5 . In hard water areas add scale inhibitor to minimise calcium deposits. 6 . Test pH and balance water with either Dry Acid (pH-) or Alkali (pH+), as required. 7 . Test   Total   Alkalinity   is   between   00   and   200   PPM.   Adjust   by   adding   Total   Alkalinity   Plus   to   raise   the   level,   or   Dry Acid   to   lower.   Failure   to   maintain   this   level   may   lead   to   corrosion,   and   will   result   in   the   pool   being   constantly   out   of balance and difficult to maintain. 8 . Shock dose with one of the following: Calcium Hypochlorite Sodium Hypochlorite Non-Chlorine Shock 9 . Add Longlife Algaecide. 1 0 . Clean water line with tile and liner cleaner. 1 1 . Dose with your usual sanitiser: Chlorine granules, Chlorine tablets, Bromine Tablets, Active oxygen-Bayroklar. 1 2 . Add flocculant for crystal clear, "polished" water. 1 3 . Recommission summer cover and roller. 1 4 . Reconnect heater and test. Return to Contents --------------------------------------------------------------------------------   POOL CLOSING PROCEDURE  1 . Vac out all leaves and debris which may cause staining. 2 . Backwash the filter thoroughly to remove the dirt which should not be allowed to overwinter in the filter. 3 . Lower water level to 6" below skimmer. 4 . Adjust pH to 7.4 to maximise shock chlorine efficiency. 5 . Shock   dose   with   Calcium   Hypochlorite   or   Sodium   Hypochlorite,   and   then   adjust   pH   to   7.4   to   protect   the   internal finishes of the pool. 6 . Add winterising chemical to prevent calcium and dirt deposits forming on the internal surfaces. 7 . Float   plastic   drums/bottles,   part   filled   with   stones,   on   the   surface   and   secure   in   the   middle   so   that   they   do   not   touch the sides. They will act as a buffer should thick ice form and pressurise the pool shell at water level. 8 . Remove steps, skimmer flops and baskets. 9 . Roll up and store cover and roller. 1 0 . Fit winter debris cover to keep out debris which may stain internal pool surfaces. 1 1 . Drain down filtration, heating and pipework systems. 1 2 . Grease all exposed metal surfaces with petroleum jelly to prevent rusting. 1 3 . Drain off and remove pump where possible. If not spray with water repellent. 1 4 . Open all valves above water level and close those below. 1 5 . Switch off main electrical supply to pool equipment. This procedure should take a couple of hours, but will save days at the start of next season Return to Contents -------------------------------------------------------------------------------- TROUBLE SHOOTING PROBLEM: Test shows no chlorine even after chlorine has been added to pool water.
