WARNINGS
High Pressure Spray Can Cause Serious Injury. Observe All W arnings.
Read and understand all instruction manuals before operating equipment.
FLUID INJECTION HAZARD
General Safety
This equipment is used in a system which generates very high
fluid pressure. Spray from leaks or ruptured components can in -
ject fluid through your skin and into your body and cause ex-
tremely
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 try to stop or deflect leaks with your hand or body .
Keep
hands away from the end of the drain valve when opening
the drain valve.
Medical Alert – Airless Spray W ounds
If any fluid appears to penetrate your skin, get emergency
medical care at once. Do not treat as a simple cut. T ell the
doctor exactly what fluid was injected.
NOTE TO PHYSICIAN: Injection into the skin is a traumatic
injury. It is important to treat the injury surgically as soon
as possible. Do not delay treatment to research toxicity . T ox-
icity is a concern with some exotic coatings injected directly
into the blood stream. Consultation with a plastic surgeon or
reconstructive hand surgeon may be advisable.
Pressure Relief Procedure
To reduce the risk of serious bodily injury , including fluid injec -
tion,
splashing in the eyes or on the skin, or injury from moving
parts, always follow this procedure whenever you install,
remove,
clean or repair any part of the system.
1. Engage the spray gun safety latch and any other equip-
ment safety locks.
2.
Shut of f the air or hydraulic supply to the pump.
3. Disengage the gun safety latch.
4. Hold a metal part of the gun firmly to the side of a grounded
metal pail, and trigger the gun to relieve pressure.
5. Engage the gun safety latch.
6. Keeping your hands away from the end of the drain valve,
slowly open the drain valves (required in your system) hav -
ing
a container ready to catch the drainage.
7. Leave the drain valves open until you are ready to use the
system again.
EQUIPMENT MISUSE HAZARD
General Safety
Any misuse of the equipment or accessories, such as
overpressurizing, modifying parts, using incompatible chemi-
cals 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 , or fire, explosion or
property damage.
Never alter or modify any part of this equipment; doing so could
cause it to malfunction.
System Pressure
Do not exceed 3000 psi (210 bar) Maximum Working Pressure ,
or the maximum working pressure of the lowest rated compo-
nent or accessory in your system.
Be
sure all components and accessories are rated to withstand
the maximum working pressure of your pump.
Fluid Compatibility
Be sure that all fluids and solvents used are chemically compat -
ible
with the wetted parts shown in the T echnical Data on
page 1 and in all other components used in the system.
Installation
To clean or service the filter without shutting down the system,
install a dual filter or a filter bypass system as explained below .
The
numbers and letters in parentheses refer to Figs. 1, 2, and
3 and the Parts Drawing. Accessories and T echnical Data are
on the front page.
NOTE: Allow 3 in. (76 mm) minimum clearance below the filter
for easy removal of the bowl (10).
Fluid Drain V alve (required in all systems)
WARNING
A fluid drain valve is required in the base of each fluid filter .
Use
this drain valve to relieve fluid pressure in the filter , to
reduce the risk of serious injury , including fluid injection and
splashing in the eyes or on the skin.
Remove the 3/4 unf plug (12) from the bottom of the filter and
install
a high pressure adapter and drain valve (A,B). See Fig.
1.
Dual Filter System
This setup enables you to redirect the fluid to another filter while
one filter is cleaned or serviced.
Install two filters as shown in Fig. 1. Install four suitable shutof f
valves
(D), one at each filter and outlet, to redirect the fluid and
isolate the filter not in use.
Filter Bypass System
This setup enables you to redirect the fluid through pipes which
bypass the filter while cleaning or servicing the filter .
Install
the filter and bypass pipes as shown in Fig. 2. Install four
suitable shutof f valves (D), one each at the filter inlet, the filter
outlet, the bypass pipe inlet, and the bypass pipe outlet. These
valves redirect the fluid and isolate the filter while cleaning and
servicing.

Service
CAUTION
If the filter will not be used for a while, thoroughly clean all
the parts in solvent and blow them dry before the paint dries
and clogs the filter . T o help prevent damaging the parts, do
not clean them with a wire brush or sharp object.
Indicator
The indicator provides gradual warning of a dirty element. When
the indicator shows 3/4 red, clean the element. If not cleaned
promptly, the filter bypass valve opens and fluid will not be
filtered.
Replace
the indicator assembly (1) if the indicator is not working
correctly (it is always red or never red). See Fig. 3.
Bypass V alve
The valve opens when a dirty element causes the filter ’ s outlet
pressure to drop 15 psi (1 bar) below the inlet pressure. This
keeps the system pressure steady and prevents the element
from
collapsing.
Replace the bypass valve (2) if it is damaged or worn.
VitonO-Ring and O-Ring Backup
The o-rings seal the bowl (10) to the housing (3). If material
leaks
around the bowl, replace the o-ring (6) and o-ring backup
(7).
Follow
the Pressure Relief Procedure on page 2. Remove the
bowl and o-rings. Clean the parts in a compatible solvent. Be
careful
not to damage the o-ring or sealing surfaces of the bowl
and housing. Before assembling, lubricate the parts with No. 2
grease. Be sure the o-ring backup is installed with the groove
facing
up.
Bowl, Element and Spring
To reduce downtime, keep a spare bowl (10), element (8) and
spring (9) on hand. Before removing the bowl, direct the fluid
through
the bypass pipes or shut down the system. Relieve fluid
pressure by opening the drain valve (B). Have a container ready
to catch the drainage.
Remove the bowl, element and spring. Replace immediately
with
the spare bowl, element and spring to keep the paint from
drying on the housing (3) and other parts. Install the element
with
the dome end up. Lubricate the threads of the bowl before
screwing it into the housing. T ighten it securely .
Clean the bowl, element and spring you removed with a
compatible solvent before the paint dries. Do not use a wire
brush
or sharp object to clean. Store until needed.
NOTE: Clean the filter element (8) with a small paint brush. Blow
out lodged particles with air , and inspect for damage. Replace
if ruptured, damaged or too dirty to clean.
