WARNING
!
High pressure can cause
serious injury.
Pressure is maintained in a
pressure tank after the
system has been shut down.
Always follow this
procedure to relieve pressure
from the tank.
77-2928-R5.2 (11/2015)
CAUSE
Solvents and coatings can be
highly flammable or combustible,
especially when sprayed.
Vapors from flammable liquids can
catch fire or explode.
Static electricity is created by the
flow of fluid through the pressure
tank and hose. If all parts are not
properly grounded, sparking may
occur. Sparks can ignite vapors
from solvents and the fluid being
sprayed.
Making changes to a pressure tank
will weaken it.
Halogenated hydrocarbon
solvents – for example 1-1-1
Trichloroethane and methylene
chloride – can chemically react
with aluminum parts and
components and cause an
explosion hazard. These solvents
will also corrode the galvanized
tank coating.
Improper operation or
maintenance may create a hazard.

PRESSURE RELIEF PROCEDURE

To reduce the risk of injury, follow the pressure relief procedure below
• Before checking or servicing
any part of the spray system
1. Turn off the main air supply to the tank.
2. Close the air inlet valve located on the tank air manifold.
3. Bleed off air in the tank by turning the air relief valve (5) thumb screw counterclockwise. Wait until all
the air has escaped through the valve before removing the pressure tank cover or fill port cap.
4. Leave the air relief valve open until you have reinstalled the tank cover or fill port cap.

SAFEGUARDS
1. Adequate exhaust must be provided to keep the air
free of accumulations of flammable vapors.
2. Smoking must never be allowed in the spray area.
3. Fire extinguishing equipment must be present in the
spray area.
Keep tank at least 10 feet away from sources of ignition.
Ignition sources include hot objects, mechanical sparks,
and arcing (non -explosion proof) electrical equipment.
1. Ground the pressure tank by connecting one end of
12 gauge (minimum) ground wire to the pressure tank
and the other end to a true earth ground. Local codes
may have additional grounding requirements.
2. See illustration on page 6 for grounding and
grounding hardware required.
1. Never drill into, weld, or modify the tank in any way.
2. Do not adjust, remove, or tamper with the safety
valve. If replacement is necessary, use the same type
and rating of valve.
1. Read the label or data sheet for the material. Do
not use materials containing these solvents with
galvanized pressure tanks. Stainless steel tank models
may be used with halogenated solvents.
2. Refer to specifications chart to ensure that fluids are
chemically compatible with the tank wetted parts.
Before placing fluids or solvents in tank, always read
accompanying manufacturer's literature.
Operators should be given adequate training in the safe
use and maintenance of the equipment (in accordance
with the requirements of NFPA-33, Chapter 15 in U.S.)
Users must comply with all local and national codes
governing ventilation, fire precautions, operation,
maintenance, and housekeeping (in the U.S., these are
OSHA sections 1910.94 and 1910.107, and NFPA-33.
• Before attempting removal of
fill port cap or tank cover
• Whenever the tank is left
unattended
