8. WATER CHEMISTRY
As previously advised, for best performance and operation of your
VAPURE VP-Series Salt Chlorinator
unit, certain water balances must be maintained within your swimming pool. Have your water tested
regularly. Transport the test water in an opaque container and have the test done as soon as possible for
The
VAPURE VP-Series Salt Chlorinator
unit is designed for use with swimming pool water balanced in
accordance with the Langelier Saturation Index with a pH range of 6.8-7.8.
8.1
Chlorine
Measurement Interval: Once a week
Ideal Chlorine (Free Chlorine) Levels: 2-3ppm (2-3mg/L) and no more than 4ppm (4mg/L).Adjust the chlorine
output by pressing [+] in DDS to increase the required output set point in 1% increments up to 100%. Pressing [-]
will decrease the output in 1% increments to 0%. Running the unit for longer or shorter hours can achieve the
same result.

HANDY TIP: The colder the water the lower your output but this does not mean you need more salt. There will
always be less chlorine demand in colder water.
We recommend 3.5kg per 1000 litres of pool water and a 50,000lt new pool needs approximately 175kg of salt.
For the FRESHWATER LOW SALT SYSTEM Model: EP25LS, we recommend 1.5kg per 1000 litre of pool water.
The unit can operate on mineral/magnesium chloride salts and you should allow an extra 20-30% on the ppm for
these type of salts.
Salt should always be added to the shallow end of the pool and allowed to dissolve. Do not let the salt settle on the
y cause damage to the surface. Use your pool brush to mix the salt into the water.
Running the pump will mix the water and help the salt to dissolve.
8.2
Salt
Measurement Interval: Every 4-6 weeks
Ideal Salt Levels: 3000-3500ppm and no more than 4000ppm. For the FRESHWATER LOW SALT SYSTEM Model:
EP25LS, the ideal TDS reading is 1500-2000ppm.
Although salt is not consumed by the Chlorinator, salt is lost during backwashing, pool over w, splashing and on
bathers that use it. The correct salt level allows f
oduction levels and electricity consumption.
The salt level SHOULD NOT go below 3000ppm or 1500ppm for the EP25LS model. Operating the unit with too
little salt in the pool will cause damage to your Cell.
Salt is the essential element by which your unit operates. Not enough salt means not enough chlorine - this simple
rule governs the total operation of your VAPURE VP
your Cell
remium Salt to keep optimum salt levels.
The unit will operate with good stability on higher salt levels but it is still advisable to run at the correct level to
prevent damage. Salt levels above 4000ppm or 2500ppm in the EP25LS model may overload the unit and cause
excessive heat.
NEVER ADD SALT DIRECTLY TO THE SKIMMER BOX. This high concentration of salt will pass through
y
Low salt levels (<1000ppm) will destroy the coating on the Cell and void the warranty.
