VERY IMPORTANT SAFETY PRECAUTIONS - CHLORINE
This and the following pages titled “Very Important Safety Precautions” provide, in brief, information of
urgent importance relative to safety in the installation, operation, and maintenance of this equipment.
WARNING
TO AVOID POSSIBLE SEVERE PERSONAL INJURY OR EQUIPMENT DAMAGE, OBSERVE
THE FOLLOWING:
THISEQUIPMENTSHOULD BE INSTALLED,OPERATED,ANDSERVICE ONLYBYTRAINED,
QUALIFIED PERSONNEL WHO ARE THOROUGHLY FAMILIAR WITH THE ENTIRE CON-
TENTS OF THIS INSTRUCTION BOOK AND THE CHLORINE GAS HANDLING MANUAL.
CHLORINE GAS IS A RESPIRATORY IRRITANT. EXPOSURE TO CHLORINE GAS IN SUFFI-
CIENT CONCENTRATION PRODUCES IRRITATION OF THE MUCOUS MEMBRANES, THE
RESPIRATORY SYSTEM, AND THE SKIN. IN EXTREME CASES, SUFFOCATION AND DEATH
CAN OCCUR.
WHEN CHANGING CHLORINE CYLINDERS, IT IS RECOMMENDED PRACTICE TO HAVE
AN APPROVED GAS MASK AVAILABLE THAT YOU HAVE BEEN TRAINED TO USE AND
YOU MUCH BE COMPLETELY FAMILIAR WITH YOUR LOCAL PLANT OPERATING AND
EMERGENCY PROCEDURES AND CHLORINE INSTITUTE RECOMMENDED EMERGENCY
PROCEDURES.
DO NOT TOLERATE ANY CHLORINE LEAKS. CHLORINE LEAKS NEVER GET BETTER.
CHLORINE LEAKS ALWAYS GET PROGRESSIVELY WORSE IF THEY ARE NOT PROMPTLY
CORRECTED.ITIS RECOMMENDED PRACTICE TOHAVEAN APPROVED GAS MASK AVAIL-
ABLE WHEN MAKING LEAK CHECKS.
AS SOON AS THERE IS ANY INDICATION OF CHLORINE IN THE AIR, TAKE IMMEDIATE
STEPS TO CORRECT THE CONDITION.
IMPORTANT INFORMATION RELATED TO SAFETY OF CHLORINATION EQUIPMENT IN-
STALLATION IS PROVIDED IN THE CHLORINE GAS HANDLING MANUAL. IN THE INTER-
EST OF SAFE OPERATION, THIS INFORMATION MUST BE READ, UNDERSTOOD, AND
PRACTICED BY EQUIPMENT OPERATORS AND THEIR SUPERVISORS.
AT TIME OF INITIAL INSTALLATION, WHEN CHLORINE SUPPLY LINES HAVE BEEN DIS-
CONNECTEDFORANYREASONANDONAROUTINEDAILY BASIS, THOROUGHLY CHECK
ALL JOINTS, CONNECTIONS, AND EQUIPMENT FOR POSSIBLE CHLORINE LEAKS AND
IMMEDIATELY CORRECT ANY THAT MAY BE FOUND.

VERY IMPORTANT SAFETY PRECAUTIONS - CHLORINE (CONT’D)
WHEN ANY CONNECTION IS BROKEN EVEN FOR A SHORT TIME, IMMEDIATELY PLUG
THE RESULTANT OPENINGS WITH A RUBBER STOPPER OR EQUIVALENT TO PREVENT
THE ENTRANCE OF MOISTURE. MOISTURE MUST BE EXCLUDED FROM ANY PART OF
THE EQUIPMENT THAT IS NORMALLY EXPOSED TO DRY CHLORINE ONLY. WHILE DRY
CHLORINE IS NON-CORROSIVE, MOIST CHLORINE IS EXTREMELY CORROSIVE TO COM-
MON METALS, SUCH AS BRASS OR STEEL.
THE TWO MOST COMMON CAUSES OF CHLORINE PIPING LEAKS ARE:
1. RE-USE OF GASKETS. THIS SHOULD NEVER BE DONE. ALWAYS HAVE AN AD-
EQUATE SUPPLY ONHANDAND ALWAYS USE NEWGASKETSOF THE CORRECT
MATERIAL AND SIZE AS IDENTIFIED ON THE EQUIPMENT PARTS DRAWING.
2. IMPROPERLY MADE-UP THREADED PIPE JOINTS. SEE CHLORINE GAS HAN-
DLING MANUAL FOR RECOMMENDED PROCEDURE.
EXCEPT IN CASES OF LEAK DETECTION OR CALIBRATION ADJUSTMENTS, THE CHLO-
RINEGASSUPPLY MUST BE SHUT OFF ATTHEGAS SUPPLYCONTAINERSANDTHE CHLO-
RINE GAS IN THE SYSTEM EXHAUSTED BEFORE SERVICING THE EQUIPMENT.
USE ONLY USF/W&T LISTED PARTS, EXCEPT FOR COMMERCIALLY AVAILABLE PARTS
ASIDENTIFIEDON THE PARTS LIST.THEUSE OF UNLISTED PARTS CAN RESULTINEQUIP-
MENT MALFUNCTIONS HAVE HAZARDOUS CONSEQUENCES.
DO NOT DISCARD THIS INSTRUCTION BOOK UPON COMPLETION OF INSTALLATION.

2.9 Injector Suction Connection
Except in those instances where the injector is installed in the control
module, a line must be provided to carry the gas from the module to the
injector. The piping must be sized as required to obtain six inches of
mercury minimum vacuum at the module.
2.10 Injector Water Supply
Theinjectorrequiresasupplyofreasonablyclean water. Equip the water
supplyuptoandincludingtwo-inchsizeswithastrainer,asindicatedinthe
Typical Installation drawing in this section. The pressure and quantity of
water required varies from one installation to another.
2.11 Drain
Two-inch bellofram type injectors used for start-stop operation require a
1/4-inchIDdrainhosetodisposeofashortspurtofwaterwhentheinjector
is operated. Run the drain hose to a suitable floor drain or waste pipe.
Forone-inchand3/4-inchfixedthroatinjectors,nofloordrainisrequired;
however, a drain is always desirable to facilitate injector service.
2.12 Injector Discharge
For3/4-inch fixed throat injector,the tailway (beige color) is designed to
accept3/4-inchpolyethylenetubingor3/4-inchthreadedpipeconnection.
NOTE: For pipe thread connection, do not cut off the serrated sec-
tion.
For one-inch fixed throat injectors, a rigid PVC pipe or USF/W&T solu-
tionhoseisrequiredbetweentheinjectordischargeandthepointofappli-
cation.Thepipe size depends on the size ofthethroat and tailway used in
the injector, the operating water pressure, and length of the solution line.
Solution hose may be connected directly to the injector tailway. If rigid
PVCpipe is used,apieceofstraight pipe atleasteightinches long should
be coupled to the end of the injector tailway before any elbows, tees, or
Saunders valves are used. This is to prevent any flow disturbances that
could affect the hydraulic performance of the tailway connections (see
Dwg. 25.200.003.010).

if possible, and is located in a nonstagnant area.
2.14 Vacuum Regulator
A vacuum regulator (or vacuum regulator-check unit), which is a gas
pressure reducing valve (and check), is connected to the control module
inlet. Refer to the separate instruction book supplied with the unit for
installation instructions for the unit.
2.15 Leak Check

2.16 Injector Arrangements for Intermittent Start-Stop Operation
Ifthegasfeederistobeoperatedintermittentlyinconjunctionwithapump
orotherequipment, this is usually accomplished by oneof the following:
• Two-inch injectors with three-way shut-off valves may be fitted with
solenoid valves as shown in Dwgs. 25.100.006.122, 25.100.006.142,
and/or 25.100.006.152 in this section. Material for this purpose is
furnished only when specifically listed in the order.
• Other injectors may be shut off by means of an electrically operated
valve in the water supply line to the injector. In this case, flexible
polyethylene or rigid PVC pipe is recommended for a minimum of
three feet immediately upstream of the injector. This should reduce
corrosionofmetalpipe and components (valves, pump impellers, etc.)
caused by diffusion of chlorine solution during shut-down periods.
