WARNING: HAZARDOUS GAS IS PRESENT IN THIS EQUIPMENT DURING
NORMAL OPERATION. TO AVOID POSSIBLE SEVERE PERSONAL INJURY
OR DAMAGE TO THE EQUIPMENT, READ THIS INSTRUCTION BOOK AND
THE APPROPRIATE GAS MANUAL BEFORE CONNECTING THIS EQUIP-
MENT TO A SUPPLY OF GAS. OPERATION AND MAINTENANCE OF THIS
EQUIPMENT MUST BE RESTRICTED TO TRAINED, QUALIFIED PERSONNEL

4.1 General
WARNING: EXCEPT WHEN DETECTING LEAKS OR MAKING CALIBRA-
TION ADJUSTMENTS, TO AVOID POSSIBLE SEVERE PERSONAL INJURY
OR EQUIPMENT DAMAGE, THE GAS SUPPLY MUST BE SHUT OFF AT
THE GAS SUPPLY CONTAINER(S) AND THE GAS IN THE SYSTEM MUST
BE COMPLETELY EXHAUSTED BEFORE BREAKING ANY CONNECTIONS
AND SERVICING THE EQUIPMENT. TO DO THIS, TURN OFF THE GAS
SUPPLY AT THE CONTAINER VALVE, WAIT UNTIL THE SUPPLY VACUUM
GAUGE READS FULL SCALE AND THE ROTAMETER FLOAT RESTS ON THE
BOTTOM STOP, AND THEN TURN OFF THE INJECTOR WATER SUPPLY.
NOTE: Refer to the automatic controller and the positioner Instruction Books
for service instructions, if the automatic version is used.
Maintenance is simplified if certain general precautions are taken. These are
usually easy to accomplish and will contribute to reducing maintenance costs
by maintaining normal operating conditions. Before reassembling removed
parts, apply Halocarbon grease U27546 to all ACME threads and Teflon tape
to all tapered threaded joints.
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 SEVERE PERSONAL INJURY OR EQUIP-
MENT 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.
For checking leakage of chlorine gas at joints, valves etc., hold the moistened
dauber of the ammonia close to the joint or suspected leakage area. If leakage
exists, a white cloud will form. When a leak is found, immediately shut off
the gas supply and remove the escaped gas by ventilation. Continue injector
