_. PRECAUTIONS
Always store primers, cleaner, and cements in cool,
dry, well ventilated places. Do not store them near
heat, sparks, or flames. Keep containers closed. Use
them in well ventilated areas. Wear impervious cloth-
ing while handling. Do not smoke, eat, or drink while
handling. Wash thoroughly after handling and before
eating. Wear eye protection when handling. If swal-
lowed, drink water, do not induce vomiting, and call a
physician or poison control center immediately. If
inhaled, get fresh air and seek medical attention if ill
feelings persist. In case of eye and skin contact, imme-
diately flush with plenty of water for 15 minutes and
seek medical attention if irritation persists. KEEP
OUT OR REACH OF CHILDREN.
All primers, cleaners, and cements must meet all local codes and
applicable standards of the American Society For Testing
Materials Standards.
Before using primers, cleaners, and cements, stir or shake, mak-
ing sure contents are liquid. Do not use if found to be lumpy or
jelly-like.
1. Cut pipe ends squarely removing all burrs and dirt.
2. Dry fit pipe and fittings to be connected for proper fit.
3. Clean pipe and fitting with a primer/cleaner.
4. Apply a thin coat of cement to fitting, avoiding puddling
inside.
5. Apply a liberal coat of cement to pipe leaving no voids.
6. QUICKLY assemble parts while cement is flui!! If you wait
too long, re-coat pipes.
7. Push pipe completely into socket of fitting, turning as it goes
until it bottoms.
8. Hold pipe and fitting together for 30 seconds. Then carefully
clean off"excess with a cloth. Allow connections a sufficient
time to cure before disturbing.
9. Remember that vent pipes must be adequately and securely
supported.

NOTE: Two 45 elbows are equivalent to one 90 elbow.
One 90° elbow equals 5 feet of equivalent vent length.
