Chlorine – general If it is a new installation, add enough chlorine (liquid or granular) to achieve a reading of 3ppm on an appropriate test kit. Stabiliser – general If the pool is outdoors, it is vital that stabiliser (also known as cyanurate and cyanuric acid) be added and maintained at 50ppm. This compound reduces chlorine destruction due to sunlight. However, too much stabiliser will reduce the effectiveness of chlorine and can result in poor quality water so ensure stabiliser does not exceed 80ppm. Good stabiliser level keeps good chlorine levels and reduces maintenance. PH For chlorine to be effective, the pH must be within a certain range.

This is usually between 6.8 (fibreglass/liner pools) or 7.2 (concrete/plaster) and 7.8. Adjust pH down with acid – powder, liquid sulphuric or liquid hydrochloric. Be very careful with acid as it can be harmful and corrosive. Total Alkalinity (TA) Total alkalinity is also known as carbonate hardness or TA for short. The recommended level is between 80 and 120ppm. TA is related to pH in that it stops the pH from varying quickly with small additions of acidic or alkaline chemicals. When the TA is low it is almost impossible to control the pH.

To raise the TA, buffer (sodium bicarbonate) is added. This must be done slowly as buffer will also cause the pH to rise. As an approximate rule every increase of 20ppm of TA will also cause a 0.1 rise in pH. Once buffer is added it should be left to mix in the pool for a few hours before reducing the pH.

Phosphates and Nitrates Phosphate and ammonia nitrogen will make your garden green – and they will do the same thing to your pool. Check for phosphates and add phosphate remover if necessary.

Don’t let fertiliser get into your pool! Phosphates are also in some cleaning products – check the label if using around your pool. For your Controller to maintain your pool balance correctly you must maintain some factors yourself: STABILISER (Cyanurates): 50 – 60ppm TOTAL ALKALINITY (TA): 80 – 120ppm PHOSPHATE: zero SALT (Standard Salt Chlorinators): 3000 – 5000ppm / Extra Low Salt XLS Chlorinators: 900 – 2000ppm Never add salt until the level has been checked BASIC POOL OPERATION The Controller uses a multi-electrode (probe) to measure and automatically adjust the chlorine and pH levels of the water in all types of pools. Once levels are finally set or adjusted, the Controller should be left alone. The Controller has been factory-set to achieve a chlorine ORP of 650mV (millivolts) and a pH of 7.6.

As all pools are different you may need to adjust the ORP for your particular pool conditions. For information on ORP please refer to the Controller manual.

If the unit is used with these factory-set points as the selected levels, it should obtain approximately 1-3ppm chlorine and 7.6pH, providing the stabiliser level is at 50ppm. If the stabiliser level is 30ppm or less, the chlorine will be around 1ppm or less. Stabiliser reduces chlorine consumption and raises the chlorine residual for the same ORP. Low stabiliser will create difficulty in achieving good water quality, and require more chlorine.

NORMAL POOL OPERATION Weekly Maintenance If the pool is heavily used (such as in hot weather) it must be checked more frequently. As a general guide it is recommended that the check should be made at least twice weekly in the swimming season and once every two weeks in the non-swimming period. Seek guidance from your local authority or qualified pool maintenance technician if necessary. • Check and clean pump and Vantage leaf baskets if required.

• Check filter and backwash the sand filter or clean cartridge filter as necessary. • Make sure there is adequate diluted acid in the tank of the automatic feeder for the next week. IMPORTANT: Always add concentrated acid to the water (not the water to the concentrated acid).
