1) Stop watering garden around pool area prior to Marblite to ensure that the shell dries out
completely. Only start watering your garden after pool is filled.
SWITCH OFF ALL IRRIGATION UNTIL POOL IS FULL
2) AFTER YOUR POOL HAS BEEN MARBLITED KEEP ALL ANIMALS AND
PEOPLE AWAY FROM IMMEDIATE POOL AREA. Trees can cause permanent
damage, make sure precautions are taken.
(We will fill the pool the following day)
3) Sweep pool daily for the first month, and 3 times a week thereafter. The reason
for this is the following : after we Marblite your pool, it will be white, if you don’t sweep
it, dust settles on the Marblite and you will get brown marks. We can not be held
responsible for that as you have to sweep it, we are not there to do it. A person can
clearly see which pools get swept and which ones don’t. That is your responsibility.
4) Vacuum pool manually for first 2 weeks for best results.
5) Wait for 14 days before putting an automatic pool cleaner in.
6) Never put HTH directly in pool, always in the weir, while the pump is running. (1 cup every
7) Test chlorine level twice a week. Before adding Hydrochloric Acid, water should be
tested, and if necessary applied at the return flow and be checked on a 14 day interval
according to test kit readings. On a new pool, only adjust acid levels after 14 days. Use
only hydrochloric acid to prevent possible brown staining caused by sulphates found
in sulphuric acid.
8) Test pH level of pool every week. Maintain at a level of 7,2. Higher levels
can cause eye irritation, lead to formation of calcium scale on the Marblite, cloudy
water and reduce the effectiveness of chlorine. PH levels below 7,0 cause itching,
brown staining of Marblite as well as steel corrosion. Before you add acid to correct
the pH level, balance the total alkalinity and correct the calcium hardness to avoid
staining the new Marblite.
9) Clean basket in weir and in pump on a weekly basis.
10) Ensure that all water passes through the filter twice daily by running the pump for
about 12 hours each day in summer.
11) Ensure the pump is switched off when operating the multi-port valve.
A) MULTI-PORT CONTROL VALVE (This valve has 6 positions)
1) FILTER: Used in the course of normal filtration.
2) WASTE: Used to bypass the filter when draining the pool or
vacuuming a heavy dirt load from the pool direct to waste.
3) CLOSED: Used only if filter lid has to be opened for maintenance
Purposes or when the pump is sited below water level.
(Never run pump with valve in this position)
4) BACKWASH: This position reserves the water flow and lifts the
trapped dirt from the sand bed pumping it to waste.
5) BYPASS: Used for circulation without filtration: this position is not
normally used in swimming pool applications.
6) RINSE: This position is used after backwash to avoid a discharge of
dirty water returning to the pool after backwash.
1) Select “backwash” on the valve and turn on the pump.
2) Watch the sight glass on the valve. When water in the sight glass is clear,
turn off the pump (2 – 3 minutes)
3) Select rinse on the valve (moving handle in a clockwise direction) and
turn on the pump.
4) When sight glass is clear (approximately 30 – 45 seconds) turn off the
5) Select “filter” on the valve (once again turning the handle clockwise) and
turn the pump on.
(BACKWASH PROCEDURE SHOULD BE DONE REGULARLY
12) Before backwashing, ensure baskets are clean and automatic pool cleaner is
disconnected from the system to maximise the flow rate of water for efficient
13) We cannot be held responsible for any discolouring caused due to incorrect
chemical application. Use granular chlorine or HTH. floater.
Consult your pool chemical company if you are in doubt.
14) Burn out algae spore build-ups by shock treating your pool at least once a
month during summer, and once every 7 – 10 days for stabilised pools.
15) Above applies to municipal water and not borehole water, if using borehole water
let it be tested by an experienced chemist.
16) Do not overdose with chemicals in the hope of keeping your pool clean over periods
when you are away. Care should also be taken when the pool is covered and left for
