Carlisle DEVILBISS HD-503 User manual

Important: Before using this
equipment, read all safety precautions
and instructions. Keep for future use.
NOTE
DESCRIPTION
This hose/gun cleaner provides a means of
cleaning the inside of material hose, fluid
passageways of spray guns and other paint
equipment. It is designed to mix solvents and
compressed air to pressure ush paint lines and
passages quickly and thoroughly, eliminating
color contamination and saving time. This re-
sults in clean and dry paint passageways using
less than 25% of cleaning solvents required in
wet ush systems.
SPECIFICATIONS
Fluid Capacity: 2 quarts
Dry Weight: 5 lbs.
Maximum Working Pressure: 50 PSI
Air Inlet Size Ball Valve: 1/4” NPS(M)
Fluid Outlet Size: Ball Valve 3/8” NPS(M)
WETTED PARTS
Wetted parts are aluminum, nickle plated brass,
PTFE and santoprene gasket.
Halogenated Hydrocarbon solvents -
for example; 1, 1, 1 - Trichloroethane
and Methylene Chloride - can
chemically react with the aluminum in
this hose/gun cleaner and cause an
explosion hazard. Read the label or
data sheet for the material you intend
to spray. Do not use materials
containing these solvents with the
hose/gun cleaner listed above.
!
WARNING
INSTALLATION
To prevent sparks from static electricity,
you must ground:
1. The hose/gun cleaner
2. The gun or tool attached to the uid
hose line from the equipment cleaner.
3. The waste container.
To ground equipment:
1. Use air hose containing a static electric-
ity grounding wire.
2. Attach one end of a ground wire to each
item listed above.
3. Attach the other end of the wire to a
water pipe, metal electrical conduit or
any pipe or structural member known
to be grounded.
A safety valve protects the cleaner from
over pressurization. During each use,
pull the ring on the safety valve to make
sure it operates freely and relieves air
pressure. If the valve is stuck, does not
operate freely or does not relieve air
pressure, it must be replaced. Do not
eliminate, make adjustments or substitu-
tions to this valve.
Static electricity is produced when
using this hose/gun cleaner. Static
electricity sparks may be created
during the cleaning operation. A spark
from static electricity may cause fire
or explosion. If the gun or tool
attached to the fluid hose line is not
grounded, it will build a static charge.
!
WARNING
Over pressurized equipment and
hoses may be damaged or subject to
hazardous bursting. Your hose/gun
cleaner is designed to have a
maximum working pressure (MWP) of
50 psi. Always use hose and
accessories designed for this
maximum fluid pressure.
!
WARNING
Air pressure loads that are higher
than design loads, or changes to the
hose/gun cleaner can cause it to
rupture or explode.
!
WARNING
The maximum working pressure of the
cleaner is 50 psi.
OPERATION
When spraying is complete, back ush remain-
ing material in spray gun and hose as follows:
1. Turn off air to material tank and bleed air
out of the material tank.
2. Loosen clamps on tank lid. Tip lid so material
will run out of uid tube into material tank.
3. Loosen air cap on gun several turns and hold
rag over cap. Pull trigger and force material
from gun and hose back into tank.
To clean hose and gun passages:
1. Fill hose/gun cleaner with suitable cleaning
solvent (see “Warning” in Column 1 on
Halogenated Hydrocarbon solvents). Close
lid on cleaner.
2. Connect air hose to 1/4” NPS(M) ball valve on
gun/hose cleaner. Close ball valve. Regulate
air pressure (must be remotely regulated) to
a maximum of 50 psig.
3. Disconnect material hose from material sup-
ply tank and connect to 3/8” NPS(M) ball
valve on hose/gun cleaner.
4. When ready to clean, open both ball valves
on hose/gun cleaner.
5. Turn metering valve on top of hose/gun
cleaner to adjust amount of solvent - air
ratio. Turn counterclockwise to increase,
clockwise to decrease. Fully clockwise shuts
off solvent completely. To begin, open coun-
terclockwise at least 2 turns for sufcient
solvent for cleaning.
6. Trigger gun with solvent going into spray
booth or properly grounded container. Con-
tinue spraying until solvent is clear with no
traces of paint.
7. Turn metering valve on hose/gun cleaner fully
clockwise shutting off solvent ow, while al-
lowing air to continue to ow. Continue until
solvent residue is removed.
8. Turn off air at source. Trigger gun to remove
residual air pressure. Close both ball valves
on hose/gun cleaner.
PREVENTIVE MAINTENANCE
Check lid gasket (7) and needle valve gasket
(2) for signs of wear or damage. Replace as
needed.
Changes to the hose/gun cleaner will
weaken it. Never drill into, weld, or
change the hose/gun cleaner in any
way.
