MAINTENANCE OF POWER SUPPLY
Little, or no maintenance is typically required. However, it is essential that the wall or post to which the
EcoSalt2 is installed be sprayed (not the EcoSalt2 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”.
MAINTENANCE OF THE IN-LINE ELECTROLYTIC CELL
The EcoSalt2 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 EcoSalt2 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 EcoSalt2 replacement
cell to match your system. The correct EcoSalt2 replacement cells to use are shown in the table below:
Model Replacement Cell Code
DES2-15E DES2C15REP
DES2-15EL DES2C25REP
DES2-25E
DES2C25REP
DES2-25EL DES2C35REP
DES2-35E
DES2C35REP
ALWAYS INSIST ON GENUINE DAVEY REPLACEMENT PARTS.
If it is necessary to replace the in- line electrolytic cell, beware
of “look-a-likes”. Only the Genuine EcoSalt2 cell is designed
and warranted to operate with the EcoSalt2 Power Supply.
SERIOUS DAMAGE MAY RESULT TO THE ELECTRONICS
INSIDE THE EcoSalt2, IF CLONE CELLS ARE USED. THIS MAY
ALSO VOID WARRANTY.
TO CLEAN THE EcoSalt2 IN-LINE CELL
Ensure that the EcoSalt2 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.
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.
