Maintenance of Your ECO-matic (Continued)
Cleaning The ‘Cell’
Mineral salts, calcium, etc. (scale) will accumulate onto the ‘Cell’ and may effect the efficiency of the ‘Cell’ in its production
of sanitizer. If allowed to build up unchecked, this scale can damage the ‘Cell’. It is therefore essential that the ‘Cell’ be
cleaned whenever necessary, as indicated by visual inspection, a drop in Output and/or RED LED(s).
The rate at which the scale accumulates on the ‘Cell’ varies from pool to pool and is influenced mostly by the Total
Hardness, Total Alkalinity and the ratio of these two important components of water balance. Rapid scaling on the ‘Cell’
indicates the need to adjust either the Total Hardness and/or the Total Alkalinity of the pool water (refer to Maintenance of
the Water).
Removing The ‘Cell’ For Cleaning
The ‘Cell’ leads connect to the ‘Cell’ Head with push-in bayonet type connectors.
Simply twist and pull each connector to disconnect. The Gas Sensor lead is a
push-on connection – simply pull to disconnect. Do not attempt to remove by pulling
on the wires. Be sure to color-match the connectors when reconnecting.
If a ‘Cell’ Head Cover is fitted to your ‘Cell’ it can be removed by undoing the screws
which holds it in place.
How To Clean The ‘Cell’
• Turn OFF filter pump before attempting to clean the ‘Cell’.
• Remove the ‘Cell’ from the ‘Cell Housing’ by unscrewing the ‘Cell’ Head (Note: left-hand thread. Turn in direction of
‘OPEN’ arrow on ‘Cell’ Housing).
• Immerse the ‘Cell’ into the weak acid solution (see below) for as short a time as necessary for the scale to be dissolved
off the ‘Cell’
• If necessary, remove the ‘Cell’ from the weak acid solution, brush with a soft brush (never use a metal brush) to help
remove stubborn scale, then re-immerse into the weak acid solution. Repeat until ‘Cell’ is completely clean of scale.
• Remember to also clean scale off head of Gas Sensor bolt (on inside of ‘Cell’ head).
• Either rinse the acid solution off the ‘Cell’ using fresh water, or immediately replace the ‘Cell’ into the ‘Cell Housing and
start the filter (so the pool water rinses the ‘Cell’).
NEVER tap or knock the ‘Cell’ against hard objects to help remove scale. ‘Cell’ will break.
NEVER clean the ‘Cell’ in undiluted acid solution (always dilute in water – see below).
NEVER leave the ‘Cell’ immersed for long periods in the acid solution (remove and rinse as soon as scale is removed).
When re-inserting the ‘Cell’ into the ‘Cell Housing’, ensure that the O-ring is in place (seated in the groove in the ‘Cell’
Head). If it is difficult to have the O-ring stay in its groove, apply lube gel to O-ring, then re-fit into groove. Do not over-
tighten the ‘Cell’ (hand tight is OK).
Weak Acid Solution
Add 10 parts water to the ‘Cell’ cleaning container, then add 1 part acid (pool acid, muriatic acid) to the water, to a total
depth which allows all of the ‘Cell’ mesh to be immersed.
Warning: NEVER add water-to-acid. ALWAYS add acid-to-water
The weak acid solution can be stored in a safe place (where children cannot access it) and re-used several times before
becoming ineffective (saves having to make the solution each time). Avoid getting the acid
solution on skin or in your eyes. If you accidentally do so, wash off immediately with fresh
water (or use the pool/spa water).
Please do not hesitate to contact your ECO-matic Dealer for any assistance regarding
‘Cell’ cleaning.
