Electrical Connections
Mains Connection
The Power Supply has a power cord attached to the left-hand side of its bottom panel. The power cord should be
connected to mains power using the correct sized male plug or by hardwiring straight into the control box. The earth
must be connected. The General Purpose Outlet / Control Box to which the unit is connected should be protected by a
Residual Current Device (RCD Safety Switch), see local electrical regulations.
The electrical supply to the unit should be interlocked to the main pump(s). That is, if the main pump(s) are turned off, so
is power to the unit.
Connecting the electrolytic cell to the power supply
The Power Supply is fitted with a flexible power lead terminated with brass compression connectors. These must be
securely fitted to the rod terminals on the underside of the cell. Fit black connectors to the outer rods and fit the white
connector to the middle rod. Use spanners to tighten the nuts on the brass connectors for a secure fit.
The blue flow sensor must be pushed onto the thread of the small bolt on the top of the
cell and fitted securely.
Pre Start-Up Procedure
Before operating your ECO-matic chlorinator please ensure the following items have been added to your pool:
Salt
Load salt into the pool at a minimum rate of 35 to 50 lbs per 1,000 gallons. It is best to allow 24 Hrs for salt to dissolve,
use vacuum system if fitted to assist in dispersing salt.
Brushing may be necessary to move salt towards the main drain
Salt is available at most pool supply stores, home improvement centers, hardware stores, etc, usually in 40 lb, 50 lb, or
80 lb bags.
Chlorine
For a new pool installation that has not yet been chlorinated, add sufficient chlorine (liquid or granular) to achieve a
reading of 3 ppm (free CI2) (with a suitable test kit), or run the chlorinator system continuously for at least 24 hours or
until a reading of 3 ppm (free CI2) is reached.
Stabilizer
For outdoor pools it is essential that pool stabilizer be added and maintained at the rate of 25 ppm (25 mg/L) at all times.
Do not exceed 50 ppm.
