HAZARD
General Safety
This equipment generates very high fluid pressure. Spray from
the gun, leaks or ruptured components can inject fluid
through your skin and into your body and cause extremely
serious bodily injury, including the need for amputation. Also,
fluid injected or splashed into the eyes or on the skin can
cause serious damage.
NEVER point the spray gun at anyone or at any part of the
body. NEVER put hand or fingers over the spray tip. NEVER
try to “blow back” paint; this is NOT an air spray system.
ALWAYS

below,
before cleaning or removing the spray tip or servicing any
system equipment.
Spray Gun Safety
Devices
Be sure all gun safety devices are operating properly before
each use. Do not remove or modify any part of the gun; this
can cause a malfunction and result in serious bodily injury.

Diffuser
The gun diffuser breaks up spray and reduces the risk of fluid
injection when the tip is not installed. Check diffuser operation
regularly. Follow the Pressure Relief Procedure,
below,
then remove the spray tip. Aim the gun into a metal pail,
holding the gun firmly to the pail. Using the lowest possible
pressure, trigger the gun. If the fluid emitted is not diffused into an irregular stream, replace the diffuser immediately.
NEVER try to stop or deflect leaks with your hand or body.
Be sure equipment

properly
Spray Wounds
lf any fluid appears to penetrate your skin, get EMERGENCY
MEDICAL
CARE AT ONCE. DO NOT TREAT AS A
SIMPLE CUT. Tell the doctor exactly what fluid was injected.
NOh
to
Physician:
Injection
in the skin is a traumatic
in-
jury. It is Important to treat the Injury surgically as soon
as possible. Do not ddey treatment to research toxicity.
Toxicity is a concern with some exotic coatings injected
directly into the blood stream. Consultation
with 8 plsstic
surgeon or reconstructive
hand surgeon may be edviseble.
Tip Guard
ALWAYS have the tip guard in place on the spray gun while
soravina. The tie guard alerts YOUto the fluid iniection hazard
and he@ reduce,-but does noi prevent, the risk-of accidentally placing your fingers or any part of your body close to the
spray tip.
Trigger Guard
Always have the trigger guard in place on the gun when spraying to reduce the risk of accidentally triggering the gun if it is
dropped or bumped.
Spray Tip Safety
Use extreme caution when cleaning or changing spray tips. If
the spray tip clogs while spraying, engage the gun safety latch
immediately. ALWAYS follow the Pressure Relief Procedure and then remove the spray tip to clean it.
NEVER wipe off build-up around the spray tip until pressure is
fully relieved and the gun safety latch is engaged.
Pressure
Relief Procedure
To reduce the risk of serious bodily injury, including fluid injection, splashing fluid or solvent in the eyes or on the skin, or injury
from moving parts or electric shock, always follow this procedure whenever you shut off the sprayer, when checking or servicing any part of the spray system, when installing, cleaning or changing spray tips, and whenever you stop spraying. (1) Engage
the gun safety latch. (2) Turn the ON/OFF switch to OFF. (3) Unplug the power supply cord. (4) Disengage the gun safety latch.
(5) Hold a metal part of the gun firmly to the side of a grounded metal pail, and trigger the gun to relieve pressure. (6) Engage the
gun safety latch. (7) Open the pressure relief valve, having a container ready to catch the drainage. (8) Leave the pressure relief
valve open until you are ready to spray again.
lf you SUSp8Ct thet the spray tip or hose is completely clogged, or that pressure has not been fully relieved after following the
steps 8bov8, VERY SLOWLY loosen the tip guard retaining nut or hose end coupling and relieve pressure gradually, then loosen
tip or hose.

FIRE OR EXPLOSION HAZARD ,.L : ;
General Safety
Any misuse of the spray equipment or accessories, such as
overpressurizing,
modifying
parts, using incompatible
chemicals and fluids, or using worn or damaged parts, can
cause them to rupture and result in fluid injection, splashing in
the eyes or on the skin, or other serious bodily injury, fire, explosion or property damage.
NEVER alter or modify any part of this equipment;
could cause it to malfunction.
doing so
CHECK all spray equipment regularly and repair or replace
worn or damaged parts immediately.
Always wear protective eyewear, gloves and clothing
recommended by the fluid and solvent manufacturer.
System
as
Pressure
This sprayer can develop .5YZ23psi 1207 bar) MAXIMUM
WORKING PRESSURE. Be sure that all spray equipment and
accessories are rated to withstand the maximum working
pressure of this sprayer. DO NOT exceed the maximum working pressure of any component or accessory used in the
system.
Fluid and Solvent
Compatibility
Always read the fluid and solvent manufacturer’s
before using them in this sprayer.
If you experience any static sparking or even a slight shock
while using this equipment, STOP SPRAYING
IMMEDIATELY. Check the entire system for proper grounding. Do not
use the system again until the problem has been identified and
corrected.
Grounding
To reduce the risk of static sparking, ground the sprayer and
all other spray equipment used or located in the spray area.
CHECK your local electrical code for detailed grounding instructions for your area and type of equipment. BE SURE to
ground all of this spray equipment:
literature
High pressure fluid in the hoses can be very dangerous. If the
hose develops a leak, split or rupture due to any kind of wear,
damage or misuse, the high pressure spray emitted from it can
cause a fluid injection injury or other serious bodily injury or
property damage.
ALL FLUID HOSES MUST HAVE SPRING GUARDS ON
BOTH ENDS! The spring guards help protect the hose from
kinks or bends at or close to the coupling which can result in
hose rupture.
TIGHTEN all fluid connections securely before each use. High
pressure fluid can dislodge a loose coupling or allow high
pressure spray to be emitted from the coupling.
NEVER use a damaged hose. Before each use, check the entire hose for cuts, leaks, abrasion, bulging cover, or damage or
movement of the hose couplings. If any of these conditions
exist, replace the hose immediately. DO NOT try to recouple
high pressure hose or mend it with tape or any other device. A
repaired hose cannot contain the high pressure fluid.
HANDLE AND ROUTE HOSES CAREFULLY. Do not pull on
hoses to move equipment. Do not use fluids or solvents which
are not compatible with the inner tube and cover of the hose.
DO NOT expose Grace hose to temperatures above 1WF
(82°C) or below -40°F (-46°C).
Hose Grounding
Static electricity is created by the high velocity flow of fluid
through the pump and hose. If every part of the spray equipment is not properly grounded, sparking may occur, and the
system may become hazardous. Sparking may also occur
when plugging in or unplugging a power supply cord. Sparks
can ignite fumes from solvents and the fluid being sprayed,
dust particles and other flammable substances, whether you
are spraying indoors or outdoors, and can cause a fire or explosion and serious bodily injury and property damage.
Always plug the sprayer into an outlet at least 26 feet (6 ml
away from the sprayer and the spray erea. Do not plug in or
unplug any power supply cords in the spray area when there is
any chance of igniting fumes still in the air.
Continuity
Proper hose grounding continuity is essential to maintaining a
grounded spray system. Check the electrical resistance of your
fluid hoses at least once a week. If your hose does not have a
tag on it which specifies the maximum electrical resistance,
contact the hose supplier or manufacturer for the maximum
resistance limits. Use a resistance meter in the appropriate
range for your hose to check the resistance. If the resistance
exceeds the recommended limits, replace it immediately. An
ungrounded or poorly grounded hose can make your system
hazardous. Also read FIRE OR EXPLOSION HAZARD.
1.
plug the power supply cord, or extension cord,
each equipped with an undamaged three-prong plug, into
a properly grounded outlet. Do not use an adapter. All extension cords must have three wires and be rated for 15
amps.

Safety
Reduce the risk of injection injury, static sparking, or splashing
by following the specific flushing procedure given on page 12
of this manual. Follow the Pressure Relief Procedure on
page 4, and remove the spray tip before flushing. Hold a metal
part of the gun firmly to the side of a metal pail and use the
lowest possible fluid pressure during flushing.
Moving parts can pinch or amputate your fingers or other
body parts. KEEP CLEAR of moving parts when starting or
operating the sprayer. Unplug the sprayer, and follow the
Pressure Relief Procedure on page 2, before checking or
servicing any part of the sprayer to prevent it from starting
accidentally.

PELIGRO POR MAL US0 DEL EQUlPO ” :i ,
PELIGRO DE INCENDIO 0 EXPLOSION
Seguridad
El flujo a alta velocidad del fluid0 al pasar por la bomba y
manguera crea electricidad estatica. Si todas las partes del
equip0 pulverizador no tienen buena tierra, pueden ocurrir
chispas, convirtiendo al sistema en algo peligroso. Tambien,
pueden producirse chispas al enchufar o desenchufar el cord6n ektrico.
Estas chispas pueden inflamar 10s vapores de
10s solventes y el chorro de fluid0 pulverizado, particulas de
polvo y otras sustancias inflamables, sea al aire libre o bajo
techo, lo que podria causar una explosi6n o incendio y graves
lesiones corporales y dahos a la propiedad. Enchufar siempre
la pulverizadora a un tomacorriente que se encuentre a por lo
menos 6 m (29 pies) de la maquina y del area que se va a
rociar. No enchufar o desenchufar ningun corddn electrico en
el lugar donde se esta rociando cuando todavia exista la
posibilidad de que queden vapores inflamables en el aire.
Si ocurre una chispa de electricidad estatica o incluso un ligero
choaue electrico mientras se usa el equipo, DEJAR DE
PULVERIZAR DE INMEDIATO. Revisar todo el sistema en
busca de una tierra apropiada. No usar de nuevo el sistema
hasta haber identificado y solucionado el problema.

RELIEF VALVE
MAIN FLUID HOSE
WHIP HOBE
Your new Ultimate NovaTM 1000 Sprayer functions and
operates differently than other airless paint sprayers.
This section will help you become familiar with the
sprayer before operating it.
Pressure Control
The pressure control includes an ON/OFF switch for the
sprayer, the pressure adjusting control knob, a pressure
sensing device, and a current overload circuit breaker
with a manual reset button. Its function is to control the
motor speed so that the sprayer maintains constant
fluid pressure at the pump outlet.
Motor
The DC motor has sealed bearings and replaceable
motor brushes. Its function is to drive the displacement
pump at the rate needed to supply sufficient paint
volume at the selected pressure.
Working together, the pressure control and motor
cause the pump to cycle whenever there is fluid or
pressure demand. When the pump is cycling, the motor
sounds like an automobile starter cranking. When the
pump is not cycling, the motor hums, hums intermittently, or appears to have shut itself off. However, there
will still be power to the sprayer and it will stay
pressurized and ready to use unless you manually shut it
off and relieve pressure.
Because the motor is DC, it is less sensitive to low
voltage or voltage fluctuations than an AC motor, and a
heavy gauge extension cord of up to 150 feet (45 ml
can be used.
Drive Assembly
The sealed drive assembly transfers power from the DC
motor to the displacement pump.
8
820-047
Displacement
Pump
The positive displacement, volume-balanced pump provides equal fluid delivery on both the up and down
pump strokes. The pump has a wet-cup which, when
filled with Grace Throat Seal Liquid, helps prevent
damage to the throat packings and piston rod.
Hoses
The grounded, nylon spray hoses have spring guards on
both ends. The 50 foot (15.2 ml hose has a l/4 in. ID.
The 3 foot (0.9 ml, 3/16 in. ID whip hose allows flexible gun movement. The nylon hose material acts as a
pulsation dampener to absorb pressure fluctuations.
Spray Gun 8 Reverse-A-Clean@ Ill Spray Tip
The high pressure spray gun has a trigger safety which
prevents accidental triggering when it is engaged (see
below). The Reverse-A-Clean Ill spray tip uses high
pressure fluid to remove clogs from the spray tip
without removing it from the gun. It includes a safety tip
guard which helps reduce the risk of injection injury.
SAFETY LATCH
SHOWN ENGAGED
Reverse-A-Clean” Ill is a registered tradename of Grace Inc.
Connect
Hose and Gun
Remove the plastic plug from the pressure control
outlet nipple. Connect the main fluid hose to the fluid
outlet of the pressure control. See Fig 1. Connect the
shorter hose to the main hose and then connect a spray
gun to the other end of the hose. Don’t use thread
sealant, and don’t install the spray tip yet!
WARNING
If you are supplying your own hoses and spray
gun, be sure they are electrically grounded and
rated for at least m
psi (210 b8r) Working
Pressure and that the gun has a tip guard. This is
to reduce the risk of serious bodly injury caused by
static sparking, fluid injection or overpressurizing
and rupturing the equipment.
For two gun hookup, remove the plastic cap plug from
the l/4 npsm(f 1 nipple and connect an accessory hose
and spray gun. See Fig 1.
CAUTION
Fig 1
To avoid damaging the pressure control, which
may result in poor equipment performance and
component damage, follow these precautions:
1. Always use at least 50 ft (15 ml of nylon
spray hose.
2. Never use a wire braid hose as it is too rigid to
act as a pulsation dampener.
3. Never install any shutoff device between the
fluid outlet of the pressure control and the
first 50 ft (15 m) of spray hose.
4. Always use the main fluid outlet for one-gun
operation. Never plug this outlet.
Fill Packing Nut/Wet Cup
Pour throat seal liquid, supplied with the sprayer, into
the packing nut/wet-cup until it is l/3 full. Keep the
wet-cup filled to help protect and prolong the life of the
pump throat packings. See Fig 2.
SECONDARY
Fig 2
Check Electrical Service
Be sure the electrical service is 126 V, 60 HzAc,
15 amp (minimum) and that the outlet you use is properly grounded.
Use an extension cord which has 3 wires of minimum 12
gauge size, rated for 15 Amps, and a maximum of
150 ft (45 m) long. Longer lengths may affect sprayer
performance.
Plug In Sprayer
Be sure the ON/OFF switch is OFF. Plug the power supply cord into a grounded elec:rical outlet that is at least
26 ft (6 m) away from the spray area to reduce the
chance of a spark igniting the spray vapors. See Fig 3.
Do not remove the third prong of the power supply cord
plug, which is the grounding prong, and do not use an
adapter.
Flush the Pump
Flush the pump to remove the lightweight oil which was
left in to protect pump parts after factory testing. Refer
to page 12 for WHEN and HOW to flush.
Fig 3
Prepare the Paint
Prepare the paint according to the manufacturer’s
recommendations.
Remove any skin that may have
formed, and stir the paint to dissolve hard pigments.
Strain the paint through a fine nylon mesh bag
(available at most paint dealers) to remove particles that
could clog the spray tip. This is probably the most important step toward trouble-free spray painting.

Install the Spray Tip and Tip Guard
Be sure the gun safety latch is engaged. Install the tip
and tip guard as instructed in the separate gun or tip instruction manual.
Adjusting the Spray Pattern
Increase the pressure adjusting knob setting just until
spray from the gun is completely atomized. Refer to Fig
3. To avoid excessive overspray and fogging, and to
decrease tip wear and extend the life of the sprayer,
always use the lowest possible pressure needed to get
the desired results.
If more coverage is needed, use a larger tip rather than
increasing the pressure.
Test the spray pattern. To adjust the direction of the
spray pattern, engage the gun safety latch and loosen
the retaining nut. Position the tip so the groove is
horizontal for a horizontal pattern or vertical for a vertical pattern. Then tighten the retaining nut.
Operating Tips
These suggestions will help prevent the motor from running too hot or operating intermittently.
ODecrease the pressure when using a small tip.
l Keep the sprayer in a shaded area when spraying
outdoors.
l Turn off the sprayer and relieve pressure whenever
you stop spraying.
Cleaning a Clogged Tip
IARNING
To reduce the risk of serious bodily injury from
fluid injection, use extreme caution when clean or
changing spray tips. DO NOT hold your hand,
body, or a rag in front of the spray tip when cleaning or checking a clogged tip. Always point the
gun toward the ground or into a pail when checking to see if the tip is clear.
Never wipe off buildup around the spray tip until
pressure is fully relieved and the gun safety latch is
engaged.
DO NOT try to “blow back” paint; this is NOT an
I air spray sprayer.
Fig 4
Hold a metal part of the gun firmly against the side of a
grounded metal pail, and trigger the gun into the pail.
Hold the trigger open, turn the sprayer ON, and slowly
increase the pressure setting until the sprayer starts.
Refer to Fig 4. This procedure reduces the risk of static
electric discharge and splashing. Keep the gun triggered
until all air is forced out of the system, and the paint
flows freely from the gun. Release the trigger and
engage the gun safety latch.
10
820-047
Follow the instructions given in your separate gun or
spray tip instruction manual for cleaning a spray tip.
SHUTDOWN
AND CARE
Check the packing nut/wet-cup daily. First follow the
Pressure Relief Procedure Warning on page 10.
Keep the wet-cup l/3 full of throat seal liquid at all
times to help prevent fluid buildup on the piston rod and
premature packing wear. The packing nut should be
tight enough to stop leakage, but no tighter. Overtightening may cause binding and excessive packing
wear. Use a screwdriver and light hammer to adjust the
nut. See Fig 5.
Flush the sprayer at the end of each work day and fill it
with mineral spirits to help prevent pump corrosion and
freezing. See “Flushing Guidelines” on’page 12.
CAUTION
Never leave water or any type of paint in the
sprayer over night to: (1) prevent pump corrosion;
(21 to prevent the fluid from freezing in the pump
and pressure control which can cause loss of
pressure, stalling or serious sprayer damage.
Always use mineral spirits for the final flush.
Relieve pressure. This leaves a protective coating
of mineral spirits in the pump.
For very short shutoff periods, leave the suction tube in
the paint, follow the Pressure Relief Procedure
Warning, page 10, and clean the spray tip.
Coil the hose and hang it on the hose rack when storing
the sprayer, even for overnight, to help protect the hose
from kinking, abrasion, coupling damage, or other
damage.
Fig 5
CAUTION
When adjusting the packing nut, be careful not to
nick the cylinder threads which may be protruding
above the bearing housing. Nicks to these threads
may strip the threads in the bearing housing when
the displacement pump is removed or installed.

1. When disconnecting wires in the pressure control
assembly, use needle nose pliers to separate mating
connectors.
When reconnecting the wires, be sure the flat blade
of the insulated male connector is centered in the
wrap-around blade of the female connector when
the connection is made.
Route wires in the pressure control assembly
carefully through the legs of the U-shaped bourdon
tube, where appropriate, to avoid interfering with
the bourdon tube which moves as the pressure setting changes and to avoid pinching the wires between the pressure control box and cover.
CAUTION
Improper wire routing can result in poor sprayer
performance or damage to the pressure control.
Keep all screws, nuts, washers, gaskets, and electrical fittings removed during repair procedures.
These parts are not normally provided with replacement assemblies.
Test your repair before regular operation of the
sprayer to be sure the problem is corrected.
If the sprayer does not operate properly, review the
repair procedure again to verify that everything was
done correctly.
If necessary,
refer to the
Troubleshooting Guide to help identify other possible problems and solutions.
WARNING
To avoid serious bodily injury, including electric
shock, DO NOT touch any moving parts or electrical parts with your fingers or a tool while
inspecting the repair.

9. Perform the pressure control calibration procedure
starting on page 27, before regular operation of the
sprayer.
Stall Pressure Calibration
WARNING
USE EXTREME CAUTION WHEN PERFORMING THIS CALIBRATION
PROCEDURE to reduce the risk of
an injection injury or other serious bodily injury which can result from splashing, component rupture, electric
shock, fire, explosion, or moving parts.
NEVER attempt to increase the fluid outlet pressure
by performing this calibration in any other way.
NEVER EXCEED 3000 psi (210 bar) MAXIMUM
WORKING PRESSURE. Normal operation of the
sprayer at higher pressures could result in component rupture, fire or explosion.
AVOID touching the wires in the pressure control
assembly with your fingers or tools when the control
box cover is removed to reduce the risk of electric
shock.
This procedure sets the sprayer to 3000 psi (210 bar)
MAXIMUM WORKING PRESSURE. This procedure
must be performed whenever a new or used circuit
board, or pressure control assembly is removed and
reinstalled or replaced, to be sure the sprayer is properly calibrated.
Improper calibration can cause the sprayer to overpressurize and result in component rupture, fire or
explosion. It may also prevent the sprayer from obtaining the maximum working pressure which would
result in poor sprayer performance.
Calibration Setup (See Fig 18 and 19)
1. Follow the Pressure Relief Procedure Warning on
page 13. Remove the spray hose and gun. Install a
0.015” spray tip in the gun. Connect the gun to the
new test hose and connect the hose to the sprayer
outlet.
2. Remove the pressure control screws and cover.
lO.Remove the test gauge assembly. Flush out water
with mineral spirits.
3. Remove the elbow (88). Holding the nipple (341)
with a wrench to prevent it from turning, rotate the
tee (85) up and install the test gauge 1x1 in the tee
(851. See Fig 18.
4. Place the pump suction tube in a 5 gallon pail of
clean water.
5. Be sure the gun safety latch is engaged.
6. Use a 3/8” ignition wrench to turn the pressure adjustment nut (S) counterclockwise about two full
turns. See Fig 19.
7. With the pressure control knob at the minimum setting, turn the sprayer switch ON. See Fig 18.
THE SPRAYER SHOULD NOT STARTI
Fig 18
If it does start, shut the sprayer switch OFF,
disengage the gun safety latch, trigger the gun into a
waste container until pressure is relieved. Engage the
gun safety latch. Turn the pressure adjustment nut
IS) a little further counterclockwise. Turn the sprayer
on to be sure it does not start.
8. Slowly turn the pressure control knob clockwise to
the maximum setting and hold it there. Use a 3/8”
ignition wrench to slowly turn the pressure adjustment nut (SI clockwise until the test gauge reads
EXACTLY 3000 psi (210 bar).
