13. MAINTENANCE OF POWER SUPPLY
Little, or no maintenance is typically required. However, it is essential that the wall or post to which the
ChloroMatic Nipper is installed be sprayed (not the ChloroMatic Nipper itself) periodically with a good surface
type insect repellent, since penetration by insects may cause damage, which is not covered by your warranty.
IMPORTANT. Certain local electrical regulations state “If the supply cord is damaged, it
must be replaced by a special cord available from the manufacturer or its service agent”.
14. MAINTENANCE OF THE ELECTROLYTIC CELL
The ChloroMatic Nipper cell is composed of precious materials, and although proper maintenance can
prolong its life to the maximum, eventually the output will wear away its delicate coating, at which time it
gradually ceases to produce chlorine. Calcium (scale) is deposited on the plates as electrolysis takes place.
This build up will interfere with the flow of electrical current in the cell and thus lowers chlorine production. It
is essential to inspect the cell regularly and clean when necessary. The rate at which deposits will form on
the plate differs with each pool and can be influenced by the following:
• Calcium Hardness of the water;
• Water temperature;
• pH level;
• Water which has been chlorinated with calcium hypochlorite for an extended period; and/or
• Calcium in the plaster surfaces of a concrete pool.
Because these conditions vary so much, check the cell at least weekly to begin with to see if either scale
or a blue/green soapy substance appears on the plates. You will then be able to determine the cleaning
cycle necessary for your pool (more frequent cleaning may be required in summer). The intervals between
cleaning could get longer to the point where cleaning is only necessary a couple of times each year.
NOTE: In areas with hard water, even reverse polarity systems may require occasional
manual cleaning.
The life of the ChloroMatic Nipper cell varies substantially from one installation to another due to variations in
operating time, water quality and composition, system and cell maintenance.
Please ensure that when cell replacement is necessary you use the correct genuine ChloroMatic Nipper
replacement cell to match your system. The correct ChloroMatic Nipper replacement cells to use are shown
in the table below:
Model Replacement Cell Code
DNP15C DES2C15REPAU
DNP15CLS DES2C25REPAU
DNP25C DES2C25REPAU
DNP25CLS DES2C35REPAU
DNP35C DES2C35REPAU
ALWAYS INSIST ON GENUINE DAVEY REPLACEMENT PARTS.
If it is necessary to replace the electrolytic cell, beware of
“look-a-likes”. Only the Genuine ChloroMatic Nipper cell
is designed and warranted to operate with the ChloroMatic
Nipper Power Supply.
SERIOUS DAMAGE MAY RESULT TO THE ELECTRONICS
INSIDE THE ChloroMatic Nipper, IF CLONE CELLS ARE USED.
THIS MAY ALSO VOID WARRANTY.
14.1 TO CLEAN THE ChloroMatic Nipper CELL
Ensure that the ChloroMatic Nipper and pool pump is turned off. Failure to do so may result in the pool
pump turning on while the cell is not in place. Disconnect the flow switch and cell lead from the top of the cell
housing. Remove the cell from the pool return line by undoing the cell nut, taking care not to lose the o-rings.
