• No equipment damage. Feeds sanitizer directly to pool.
• NSF 50 Certified when paired with flow rate indicator (such as P/N R172082)
installed on inlet line.
INSTALLATION
This feeder is designed for hard plumbing installation using
1” PVC pipe and includes standard threaded inlet and
outlet fittings. It operates by pressure differential which
circulates through the feeder. The inlet line (control valve
side of feeder), connects to the plumbing between the
pump and filter. The outlet side of the feeder connects
to pool return line after the filter and/or heater, pool
cleaner, diverter valves or any other piece of equipment
(if installed). A corrosion resistant check valve such as
Rainbow’s R172288 should be installed between the
feeder inlet and outlet and the equipment to help prevent
equipment damage. DAMAGE TO THE HEATER OR
OTHER EQUIPMENT COULD RESULT FROM A HIGH
CONCENTRATION OF SANITIZER BACK FLOWING INTO
IT WHEN PUMP IS SHUT OFF. It is recommended that
feeder be bolted down.
OPERATING INSTRUCTIONS
Exercise extreme caution when operating or servicing feeder. NEVER
OPEN FEEDER WHEN PUMP IS RUNNING. DO NOT INHALE
FUMES, especially in hot weather which can create more gases.
Wear protective gear. Follow chemical manufacturer’s instructions for
handling the chemical. Before start up of feeder your pool should be
properly conditioned and the chlorine residual should be 1.0 to 1.5 ppm
(Bromine 2.0 to 4.0 ppm). Consult your local dealer for water conditioning
information in your area. Because the sanitizer demand in your pool is
dependent on many factors (sunlight, high temperatures, bather load,
etc.) your valve setting may have to be changed from time to time to
adjust to these conditions. When possible, increase the feed rate a day
or two in advance. The recommended start up setting is #1. Use a test kit
to determine the sanitizer residual. It is recommended that the sanitizer
residual be checked daily for the first 5 days to find the ideal setting.
NOTE: Higher numbers dispense more chemical. Small gradual changes
are imperative for control.
READ CAREFULLY.
This feeder is designed to use only CLEAN Trichlor-s-trizinetrione OR CLEAN Bromine tablets - slow dissolving type.
Never use dirty tablets. UNDER NO CIRCUMSTANCES MIX Trichlor or Bromine with Calcium Hypochlorite, with other
forms of concentrated chlorine or with other chemicals. Keep inside of feeder clean of dirt and debris at all times. FIRE
AND/OR TANK SEPARATION MAY RESULT.
NEVER use oils or grease to lubricate o-ring. Oil in contact with Trichlor OR Bromine may result in FIRE. Lubricate o-ring with Lifegard
Silicone o-ring Lubricant ONLY, available at your dealers. If shock treatments or Algaecides containing chemicals other than sanitizers
tablets in feeder must be used, turn off Feeder OR remove tablets until the shock or Algae treatment is complete and all granules have
dissolved. Failure to do so may result in granules mixing in feeder causing FIRE AND/OR TANK SEPARATION. The shock or algae
treatment dissolved in water is safe with tablets. If you are not the original owner of this feeder, not sure which chemicals was used, or if dirt
and/or debris inside feeder, be SAFE and flush thoroughly with fresh water. CAUTION SHOULD BE USED WHEN REMOVING CAP. DO
NOT INHALE FUMES.
CALCIUM HYPOCHLORITE IS NOT TO BE USED IN ANY FORM. Use of chemicals other than those recommended by manufacturer
may be hazardous.
READ CAREFULLY.
It is important to read all information BEFORE proceeding with the
installation. The information will guide you in installing your feeder properly and avoiding problems
due to improper isntallation. IF INSTRUCTIONS ARE NOT FOLLOWED FIRE OR TANK
SEPARATION MAY RESULT, CAUSING PROPERTY DAMAGE AND/OR PERSONAL INJURY.
IF YOUR POOL HAS COPPER PLUMBING...STOP! Never Install feeder into copper plumbing
as pipe dmage may occur.
NOTE: If a heater is used, a FIREMAN’S SWITCH or equivalent must be installed to prevent
possible damage and improper operation of CHECK VALVE and other equipment subject to heat
damage.
