WARNING: TO AVOID POSSIBLE SEVERE PERSONAL INJURY OR DAMAGE
TO THE EQUIPMENT, EXCEPT IN CASES OF LEAK DETECTION OR CALIBRA-
TION ADJUSTMENTS, THE GAS SUPPLY MUST BE COMPLETELY SHUT OFF
AT THE GAS SUPPLY CONTAINER(S), AND THE GAS IN THE SYSTEM EX-
HAUSTED BEFORE SERVICING THE EQUIPMENT. TO DO THIS, TURN OFF
THE GAS SUPPLY AT THE CONTAINER VALVE, WAIT UNTIL THE SUPPLY
VACUUM GAUGE SHOWS 100 INCHES OF WATER AND THE ROTAMETER
FLOAT RESTS ON THE BOTTOM STOP, AND THEN TURN OFF THE INJEC-
TOR WATER SUPPLY.
4.1 General Care of Equipment
Maintenance is simplified if certain general precautions are taken. These are
usually easy to accomplish and contribute to reducing maintenance costs by
maintaining normal operating conditions. The recommended precautions are
as follows.
4.1.1 Checking for Leaks
WARNING: TO AVOID POSSIBLE SEVERE PERSONAL INJURY, IT IS GOOD
PRACTICE TO HAVE AN APPROVED GAS MASK AVAILABLE WHEN MAK-
ING LEAK CHECKS.
• CHLORINE LEAKS
WARNING: TO AVOID POSSIBLE SUFFOCATION, SEVERE PERSONAL INJURY,
OR EQUIPMENT DAMAGE, DO NOT TOLERATE ANY LEAKS. THEY ALWAYS
GET PROGRESSIVELY WORSE AND MUST BE CORRECTED PROMPTLY.
NOTE: For leak testing, use Evoqua Water Technologies U409 or Commercial
26° Baume’ aqua ammonia. Household ammonia is not strong enough.
A bottle of aqua ammonia is furnished for checking leakage of chlorine
gas at joints, valves, etc. Hold the moistened dauber close to the joint or
suspected leakage area. If leakage exists, a white cloud will form. When
a leak is found, immediately shut off gas supply and remove the escaped
gas by ventilation. To remove all gas from the equipment, continue injector
operation until the supply vacuum gauge reads 100 inches of water and
the rotameter float rests on the bottom stop.
WARNING: ESCAPED GAS MUST BE EXHAUSTED TO OUTSIDE ATMO-
SPHERE. THE EXHAUST SYSTEM MUST TERMINATE IN AN AREA WHERE
GAS FUMES CANNOT CAUSE INJURY TO PERSONNEL OR DAMAGE TO
EQUIPMENT. DO NOT TERMINATE THE EXHAUST SYSTEM AT A LOCATION
ROUTINELY USED BY PERSONNEL, SUCH AS WORK AREAS OR PATHWAYS,
NOR NEAR WINDOWS OR VENTILATION SYSTEM INTAKES.
Eliminate the leak before proceeding.
