Drawing 10148 REV 0 24-11-15
Hand over procedure Explain and or demonstrate:
1. Pool and spa water to be clear, no smell and no foaming.
2. All areas close to pool to be kept clean, appropriate cleaning agents to be used that do not
contain detergents.
3. The pH must to be maintained between 7.2 and 7.8 for the chlorine donor to be efficient.
Combined chlorine will form quicker if these levels are not maintained together with an
increase in associated smell and irritation to skin and eyes. More acid or CO2 will be used
at first on a new pool due to the grouting and the controller may enter pH time-out at first
due to this. Acid reduces pH level.
4. Break point chlorination is to be maintained i.e. that free chlorine is to be no less than 2/3
of total. If break point chlorination is lost 10 times as much chlorine will be used to
re-achieve break point with the associated increase in chemical costs.
5. Under dosing of chlorine will mean that bacteria will multiply in the water.
6. Over dosing chlorine will bleach costumes (consider that fashion costumes are not suitable
for chlorine pools), irritate skin and effect bleached hair.
7. Correct use of DPD1, DPD3, phenol red, alkalinity & calcium hardness tablets,
record of tablet results to be maintained.
8. Balanced water is essential and achieved when alkalinity is between 75mg/l and 150mg/l,
calcium hardness is between 75mg/l and 500mg/l and TDS not above 1000mg/l above
source water (not salt water pools).
9. The general overview of the system to the staff, point out the sample line, the route the
sample takes through the pipe work to the sensors and the sequence of sample line isolating
valves i.e. isolation valves operation. The necessity of having a regular unchanging flow
through the sensor assembly, the function of the flow valve. The operation of the flow
switch and how this de-activates the chemical feeders.
10. That subjecting the electrodes to very high pressure or vacuum will damage the electrodes.
Indicate the electrodes and show which is which. Explain how the sensors work, are
removed and how they are cleaned with Topline cleaning solution.
11. The calibration procedure for the chlorine sensor, go through the operation of the controller,
i.e. reading, set point required level, standardisation actual level (point out that the water
sample used for standardising the electrodes must be taken from the sample tap
adjacent to the controller, not from the swimming pool), time out and proportional feed
set up, show how to set and change all the parameters as described in the operations manual
12. The dosing pumps. Show how to tighten up the set screws on dosing pump heads and
state that this should be done every six weeks. Show 4 function valve operation, foot valve
assembly and injector maintenance. Point out the dosing system supplier is not responsible
for blocked injectors or any damage caused by them.
13. CO2 controller. Show how to change the CO2 flow, clean CO2 diffuser, change over
bottles and pressure gauges, state that first stage regulator to be 1.5 bar.
