SAFETY NOTICE
MAINTENANCE OF POWER SUPPLY:
Little or no maintenance is normally required with the exception of replacing blown Fuses. These Fuses can be
sourced from your local EcoSalt ™ Dealer. However it is essential that the wall or post to which the Unit is installed
be sprayed (not the Unit itself) periodically with a good surface type insect repellent, since penetration by insects
may cause damage, which is not covered by your warranty.
The back of the Unit has been designed as a heat sink. It is normal for this area to become very hot.
MAINTENANCE OF ELECTROLYTIC CELL:
The cell is composed of precious materials, and although proper maintenance can prolong its life to the
maximum, eventually the process of electrolysis will wear away its delicate coating, at which time it gradually
ceases to produce chlorine.
Mineral salts and calcium (scale) are deposited on the outer and the inner plate as electrolysis takes place. This
build up – will interfere with the flow of electrical current in the Cell and thus lowers sanitiser 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 control
• Water which has been chlorinated with calcium hypochlorite for an extended period
• 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 when either scale or a
blue/green soapy substance appears on the plate. You will then be able to determine the cleaning cycle necessary
for your pool (obviously more in summer). The intervals between cleaning could get longer to the point where
cleaning is only necessary a few times each year. One exception is the use of bore water or ground water, in which
case cleaning may always need to be as frequent as once a week.
The life of Eco Salt ™ electrolytic cells vary 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 Eco Salt ™ replacement cell to match your system. The
correct Eco Salt ™ Replacement cells to use are shown in the table below:
EcoSalt ™ BMSC: Reverse Polarity Cells
Model Replacement Cell Code
EcoSalt 13 MO681REP
EcoSalt 20 MO682REP
EcoSalt 26 MO683REP
ALWAYS INSIST ON GENUINE ECOSALT REPLACEMENT PARTS. If it is necessary to replace the Electrolytic
Cell, beware of “look alikes”. Only the Genuine EcoSalt Cell is designed and warranted to operate with the
EcoSalt Power Supply.
SERIOUS DAMAGE MAY RESULT TO THE ELECTRONICS INSIDE THE UNIT IF COPY ELECTRODES ARE USED
AND MAY VOID WARRANTY.
To clean the EcoSalt ™ cell: Ensure that the power supply is turned off- failure to do so may result in the pool
pump turning on while the cell is not in place. Disconnect the power lead from the underside of the cell. Remove
the cell from the pool return line by undoing the unions. Take care not to lose the o-rings.
METHOD 1
Add 1 part HYDROCHLORIC ACID to 10 parts WATER in a suitable container. The Cell should be placed on a
suitable surface that allows it to form a U shape and some of the solution can be poured safely into the up-turned
cell. Take care when doing this as the solution can foam and create a spill which must be cleaned up by dilution.
As an alternative the Cell can be immersed completely in a container.
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”.
NOTE:
In areas with hard water, reverse polarity systems may require occasional manual cleaning.
