SALT: WHEN AND HOW TO ADD IT

Salt: When And How To Add It

When to add salt

Add salt when indicated on the control panel. The light marked ‘Add Salt’ functions

automatically when salt is needed. Note that the ‘Add Salt’ light may switch on at any

salt level between 3000 and 4000 ppm, depending upon the water temperature and

mains voltage (see note). This is not a fault but a precaution to ensure that the salt

level is never too low.

The salt concentration should normally be around 4000 ppm, but should never be

allowed to fall below 3000 ppm, as this can reduce the life of the cell electrodes.

Salt is not lost through evaporation. Salt is lost with the water splashed out of the

pool or during backwash. Adding fresh water or rainfall to the pool dilutes the salt

concentration. Adding salt may be needed from time to time to maintain an opti-

mum salt level.

NOTE: Even if the salt concentration is around 4000 ppm, the ‘Add Salt’ light may

switch ON if the water temperature drops below 18ºC (65ºF) or mains supply volt-

age is too low. With cold temperatures and low bather load it is not necessary to

have the chlorinator on. A manual addition of sodium hypochlorite may be all that is

needed.

How much to add

Use a salt test strip to determine salt level in pool water prior to adding any salt.

Capture water from elbows depth in a container, then use a test strip in this water

sample. Previous regular usage of sodium hypochlorite (liquid chlorine) creates

residual salt within the pool and may bring your salt level close to the required 4000

ppm concentration. Only 99.5% pure refined salt (sodium chloride) should be used

with the Clearwater chlorinator. Add enough salt to obtain a 4000 ppm

concentration.

· 1 gram per litre raises the salt level by 1000 ppm.

· In a NEW pool (where there is no salt residual) of approximately 80 000 litres,

eight 40 kg bags of salt are required to reach a 4000 ppm concentration.

· Refer to ‘Salt Chart’.
