Method one:
Add 1 part HYDROCHLORIC ACID to 10 parts WATER in a suitable container and immerse the cell in this
solution. It should not take longer than a few minutes to clean, if it does the cell should be cleaned more
frequently. If the build – up is not excessive it may be possible to clean the cell plates with a jet of running
water. Return the cell to its housing and connect leads to the head assembly.
Method two:
As an alternative, an approved commercial cell cleaning solution can be used a number of times effectively.
NOTE: Always add acid to water. Never add water, to acid. Always wear eye protection
and rubber gloves. Always clean the cell in a well-ventilated area.
14.2 RE-INSTALLING CELL AFTER CLEANING OR REPLACEMENT
When re-installing the ChloroMatic Nipper cell into the housing, ensure that the cell locking nut is tight. Do
this by turning on the pool pump once fitted, then checking for leaks.
If there is a leak, remove the lock nut and inspect the o-ring for debris, or damage. Then re-try. Before re-
fitting the cell connectors, ensure that the terminals are dry.
14.3 SAFETY DEVICE
Hydrogen Gas is a by-product of the chlorine producing process. A Flow Switch has been supplied with the
ChloroMatic Nipper, which will stop output if low or no flow is detected. The ChloroMatic Nipper system will
run to flows down to 3.6m³/h (60L/min).
15. DAY TO DAY OPERATION
Four prime rules must be observed if your unit is to give the best possible service:
15.1 STABILISER
The importance of pool stabiliser cannot be over – emphasised. It is essential in helping retain chlorine
in your pool. Chlorine is rapidly dissipated by sunlight and the use of stabiliser will reduce this dissipation
substantially. Without stabiliser, it may be necessary to run the Unit for up to three times as long!
Stabiliser should be added at the rate of 500 grams for every 10,000 litres of water. Stabiliser should be
maintained at a level of 25-50ppm. If a ORP controller is used, Stabiliser should be maintained at a level of
15-25ppm. Before adding more stabiliser, have your pool water analysed at your pool shop to ensure that
you do not add too much.
(FOR OUTDOOR POOLS ONLY, INDOOR DO NOT REQUIRE STABILISER).
