Note: If a pump load greater than 1.5Kw or the use of a 3 phase pump is required, an
interface relay must be installed.
If double adaptors or stackable plugs are employed to operate more than one pump
directly from this Pump Outlet Socket the Warranty will be void.
Please refer to your Poolrite State Office for details.
ADDING SALT TO THE POOL
Start up procedure for marble surface pools
For new concrete pools with marble plaster (marblesheen) finishes we recommend that
the salt not be added to the pool until the excess calcium compounds in the plaster
have leached out and the pH of the water has stabilised.
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 occu-
pied 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 5000 mg/l is required (for cool
climates), the amount of salt needed will be:
Salt Quantity = 60 x 5000
1000
= 300 kg
