floor and can then be vacuumed directly to waste (i.e. NOT through the filter). Following
this, the pool should gradually attain a clean, clear condition after constant filtration and
chlorination.
5. Finally, the use of LANTHANUM CARBONATE (or "Starver") is recommended to reduce the
phosphorous content to less than 1 part per billion. This starves algae of an essential element for
growth.
As a guide, the WATERMAID chlorinator may need to be run non-stop for several days
to overcome the addition of an algaecide containing ammonium compounds AND any
debris. Otherwise, a sufficient chlorine reading may be impossible to obtain for up to 4
weeks.
For spas, it is often best to drain, clean and refill. Follow the manufacturers recommended
procedure.
13. ELECTRICITY COSTS
When an Australian 240VAC model WATERMAID chlorinator is running at full capacity, it is using
420 watts of power.
{POWER (watts) = VOLTS X AMPS}
Therefore the cost to run a Watermaid chlorinator at full capacity is worked out using the
following formula:
COST = No. of X Hours X Cost Per
TO
Watts Run kWh
RUN
1000
As an example, a WATERMAID chlorinator run for 10 hours in Sydney, where the domestic cost of
electricity is 9.71 cents/kWh, will cost a total of:
= 420 / 1000 x 10 x 9.71
= 40.782
= 41 c / day

3. INSTALLATION
The WATERMAID chlorinator may be installed by the pool owner. However, these instructions
should be fully understood to ensure correct installation and safe operation. Incorrect
installation may pose a danger and/or may damage the unit thus voiding warranty. If there is
any doubt, then an experienced pool technician or plumber should carry out the installation.
(i) MEASURE THE POOL OR SPA SIZE
The size of the pool or spa determines the amount of salt to add. If the pool or spa is
rectangular, the length, breadth and average depth are multiplied. If the pool or spa has an
irregular shape, then the average of the measurements can be taken.
For pool water with no salt, align "0 ppm" in either of the following Metric or U.S.
Measurements tables with the column that represents the size of the pool, e.g. a 60,000 litre
pool with no salt would need 360 Kg (approx. 14 x 25 Kg bags) of salt.
For pool water containing salt, find the salt level (in ppm) using a WATERMAID hydrometer
or reading from a pool shop and align this value with the column that represents the size of
the pool, e.g. an 80,000 litre pool with a salt reading of 4000 ppm would need 160 Kg
(approx. 6 x 25 Kg bags) of salt.
Empty the contents of the required salt bags to the pool or spa. For pools, it is best to add the
salt to the shallow end and run the filter and pump simultaneously to circulate the water and
dissolve the salt. The WATERMAID should be turned OFF or to standby mode (refer to
section 4). The salt bag should NOT be thrown into the pool as chemicals and inks can
interfere with the water balance. Quality pool salt (with low levels of iron and other
impurities) should be used. Finer grades dissolve faster. Salt may take 24 - 48 hours to
dissolve in summer and longer in winter. Alternatively, sea water may be used.
If the pool has no main drain, place a vacuum hose head in the deep end, and sweep the salt
toward the vacuum head. The other end of the vacuum hose should be placed in the skimmer
box. Run the filter and pump with the WATERMAID chlorinator OFF to circulate the undissolved
salt in the water.
(ii) ADDING SALT TO THE POOL OR SPA
DO NOT add pool/spa chemicals directly to the
skimmer. This may damage the Cell.
Maintaining high salt levels above the
recommended range can contribute to corrosion
of
pool/spa
equipment.
Watermaid
recommends a salt concentration in the
water of 6000 ppm (refer to section 8).
If the chlorinator has already been
installed, it should be turned off or to
standby mode (refer to section 4) before
adding salt.
