The recommended stabilising period is:
●
For hand mixed/applied plaster 12 weeks.
●
For machine mixed/applied plaster 24 weeks.
During this period the pool should be sterilised with liquid chlorine.
Calculating Pool Capacity
Swimming pool grade salt (low mineral content Sodium Chloride) must be added to the
pool and allowed to completely dissolve before operating the chlorinator cell.
The amount of salt to be added cannot be calculated until the volume of water
contained in the pool is determined.
This water volume can be obtained by:
(a) Referring to the pool manufacturer’s data (if pre-moulded fibreglass).
(b) Reading the difference on the water meter before and after filling.
(c) By mathematical calculation.
Formula For Calculating Water Volume
Water Volume (m
3
) = [Surface Area (m
2
) x Average Depth (m)] minus [Volume occupied
by steps, swim-outs, etc.]
Calculating Salt To Be Added
The amount of salt to be added to the calculated volume of water in the pool depends
on the salt concentration selected.
Salt Quantity (kg) = Water Volume (m
3
) x Salt Concentration (mg/l)
1000
For example, if the calculated volume of water in your pool is 60.0 cubic metres (as per
previous example) and the minimum salt level of 6000 mg/l is required (for cool
climates), the amount of salt needed will be:
Salt Quantity = 60 x 6000
1000
= 360 kg
What Salt Concentration To Use
Although your Surechlor 4000 has been designed to operate with a wide range of salt
concentrations, the minimum recommended level is 6000 mg/l (P.P.M.). However with
heated and outdoor pools in tropical and sub-tropical climates, salt levels between
7000 and 8000 mg/l can be maintained in order to gain the benefits of increased
chlorine output, reduced cell maintenance and extended cell life.
The Chlorine Control can be switched to 100% output if higher salt levels are used
without the risk of damage occurring, due to the incorporation of electronic output
limiting on all of these model chlorinators.
