Start-up settings are based on historical data for
average chlorine consumption in Public Pools
according to pool or spa type. Outdoor Pools and
Spas consume considerably more chlorine than Pool
and Spas that are indoors. Weather, Stabilizer level
and Bather load all have a major impact on chlorine
consumption.
Important:
Always attempt to increase feed rate by
first increasing the inlet flow rate to attain the desired
free chlorine residual. If the desired free chlorine
residual can’t be attained by increasing the inlet flow
rate, add tablets to an additional cartridge.
Note: Remove unused cartridges from the Hopper
prior to start-up and store for future use.
Below are the feed rates for the CCH Feeder with the
different grids, flow rates and # of cartridges filled
with tablets. If the current feed rate is know from using
either liquid chlorine (Bleach) or trichlor, set the CCH
Feeder feeder to produce that feed rate. If the feed
rate is unknown, use either the chart or the graph to
determine the appropriate Start-up setting for the pool/
spa type and size.
Note: 1 lb of Trichlor has the equivalent of 0.9 lbs of
Av. Cl. 1 gallon of 10-12% bleach has the equivalent
of 1 lb of Av. Cl.
The CCH Feeder is NSF listed for an output rate of 18#’s of Av. Cl./day. State and local health codes will
determine the maximum pool/spa size that can be treated with a single CCH Feeder. Some states may allow the
use of multiple feeders to treat larger pools.
Calculations:
The first calculation is for a state code that requires a specific weight of Av. Cl./10,000 gallons per day.
Example 1:
The state health code requires 3 lbs Av. Cl. /10,000 gallons per day.
With an output rate of 18 lbs. Av. Cl./day the CCH Feeder will treat a pool up to 60,000 gallons per the health code.
The calculation is as follows:
18/3 x 10,000 = 60,000 gallons
