WARNING
DO NOT PLACE PLASTIC BOWL UNIT IN SERVICE
WITHOUT METAL BOWL GUARD INSTALLED
Plastic bowl units are sold only with metal bowl guards. To minimize the danger of flying fragments in
the event of plastic bowl failure, the metal bowl guards should not be removed. If the unit is in service
without the metal bowl guard installed, manufacturer's warranties are void, and the manufacturer
assumes no responsibility for any resulting loss.
IF UNIT HAS BEEN IN SERVICE AND DOES NOT HAVE A METAL BOWL GUARD, ORDER ONE
AND INSTALL BEFORE PLACING BACK IN SERVICE..
CAUTION
Certain compressor oils, chemicals, household cleaners, solvents, paints and fumes will attack plastic
bowls and can cause bowl failure. Do not use near these materials. When bowl becomes dirty replace
bowl or wipe only with clean, dry cloth. Reinstall metal bowl guard or buy and install a metal bowl guard.
Immediately replace any crazed, cracked, damaged or deteriorated plastic bowl with a metal bowl or a
new plastic bowl and metal bowl guard.

CAUTION
EXCEPT as otherwise specified by the manufacturer, this product is specifically designed for com-
pressed air service, and use with any other fluid (liquid or gas) is a misapplication. For example, use
with or injection of certain hazardous liquids or gases in the system (such as alcohol or liquid petro-
leum gas) could be harmful to the unit or result in a combustible condition or hazardous external
leakage. Manufacturer's warranties are void in the event of misapplication, and manufacturer
assumes no responsibility for any resulting loss. Before using with fluids other than air, or for non-
industrial applications, or for life support systems consult manufacturer for written approval.
