Leak Testing

WARNING
Hazard of Explosion!
Never use an open flame to detect gas leaks. Explo-
sive conditions may occur. Use a leak test solution
or other approved methods for leak testing. Failure
to follow recommended safe leak test procedures
could result in death or serious injury or equipment
or property-only-damage.

WARNING
Hazardous Pressures!
If a heat source is required to raise the tank pressure
during removal of refrigerant from cylinders, use
only warm water or heat blankets to raise the tank
temperature. Do not exceed a temperature of 150°F.
Do not, under any circumstances apply direct flame
to any portion of the cylinder. Failure to follow these
safety precautions could result in a sudden rise of
pressure possibly resulting in a violent explosion
which could result in death or serious injury.
To leak-test a chiller containing full refrigerant charge,
raise chiller pressure using a controlled hot water or
electric-resistance system to a maximum of 8 psig. Do
not use nitrogen, which will cause excessive refrigerant
discharge by the purge system.
