• Either rinse the acid solution off the ‘Cell’ using fresh water, or immediately replace the ‘Cell’ into the
‘Cell Housing and start the filter (so the pool water rinses the ‘Cell’).
NEVER tap or knock the ‘Cell’ against hard objects to help remove scale. ‘Cell’ will break.
NEVER clean the ‘Cell’ in undiluted acid solution (always dilute in water – see below).
NEVER leave the ‘Cell’ immersed for long periods in the acid solution (remove and rinse as
soon as scale is removed). Max 15-20 minutes.
When re-inserting the ‘Cell’ into t he ‘Cell Housing’, ensure that the O-ring is in place (seated in the
groove in the ‘Cell’ Head). If it is difficult to have t he O-ring stay in its groove, apply lube gel to O-ring,
then re-fit into groove. Do not over-tighten the ‘Cell’ (hand tight is OK).
Weak Acid Solution
Add 3 parts water to the ‘Cell’ cleaning container, then add 1 part acid (pool acid, muriatic acid) to the
water, to a total depth which allows all of the ‘Cell’ to be immersed. Muriatic acid is corrosive. Please
follow safety instructions and wear protective clothing.
Warning: NEVER add water-to-acid. ALWAYS add acid-to-water
The weak acid solution can be stored in a safe place and re-us ed for some time before becoming
ineffective (saves having to make the solution eac h time). Avoid getting the weak acid solution on
skin or in your eyes. If you accidentally do so, wa
sh off immediately with fresh water (or use the
pool/spa water).
Please do not hesitate to contact your ECO-matic Dealer for any assistance regarding ‘Cell’
cleaning.
Chemistry:
Salt
At startup of the Ch lorinator System there must be at least 4, 000ppm of salt (sodium chloride) in the
pool water. The salt level should not exceed 5,000ppm. This is simple to achieve if the following steps
are taken:
(i)
Know, with reasonable accuracy, the pool volume.
(ii)
Measure the pool water TDS (Total Dissolved Solids or Conductivity) prior to adding salt.
Note: the Conductivity Meter should be calibrated for sodium chloride. NOTE: Do not use Rock
Salt or salt which contains YPS or Iodine. Salt should be Fine or Medium G rade Solar Salt a t
99.4% PURE NaCl
(iii)
Calculate the required start - up salt dos e and add it to the pool. Adding 10 kg of salt p er
10,000 litres will rais e the salt concentration by 1,000 ppm (e.g.
In a pool with no salt, a
100,000 litre pool will need 450 kg of salt to reach 4,500 ppm)
•
If the pool is already operating as a salt pool, simply add enoug h salt to br ing the level to
4,500.
•
Note: Fill water can have existing salt level. Test with Conductivity Meter
