NOTICE: Stir the solvent cement
frequently while using. Use a natural
bristle brush or the dauber supplied
with the can. The proper brush size is
one inch.

WARNING: DANGER
OF FIRE OR BODILY
INJURY - Solvent cements
and primers are highly
flammable. Provide
adequate ventilation and do
not assemble near heat
source or open flame. Do not
smoke. Avoid skin or eye
contact. Observe all cautions
and warnings on material
containers.
CAUTION:
For proper installation:
DO NOT use solvent cement
that has become curdled,
lumpy or thickened.
DO NOT thin solvent
cement. Observe shelf
precautions printed on the
containers.
For applications below 32°F
use only low temperature
type solvent cement.
Appropriate solvent and
cleaner must be used for the
type of vent pipe used (PVC,
CPVC or ABS).
NOTICE: All pipe, fittings, solvent cement, primers and procedures must conform to American
National Standards Institute and American Society for Testing and Materials (ANSI/ASTM) standards.
