There is a high voltage device
that can induce an electrical

Parts being sprayed must be supported on
conveyors or hangers that are properly grounded.
The resistance between the part and earth ground
must not exceed 1 meg ohm. (Refer to NFPA-33.)
Operators must be grounded. Rubber soled
insulating shoes should not be worn. Grounding
straps on wrists or legs may be used to assure
adequate ground contact.
Operators must not be wearing or carrying any

When using an electrostatic handgun, operators
must assure contact with the handle of the applicator

Use a mask or respirator whenever there is a chance
of inhaling sprayed materials. The mask must be
compatible with the material being sprayed and its
concentration. Equipment must be as prescribed
by an industrial hygienist or safety expert, and be
NIOSH approved.
Chemical HazardToxic Substances
Sprayapplicatorsrequirethataluminuminletttings
be replaced with stainless steel.
Aluminum is widely used in other spray application
equipment - such as material pumps, regulators,
triggering valves, etc. Halogenated hydrocarbon
solvents must never be used with aluminum
equipment during spraying, ushing, or cleaning.
Read the label or data sheet for the material you
intend to spray. If in doubt as to whether or not a
coating or cleaning material is compatible, contact
your coating supplier. Any other type of solvent may
be used with aluminum equipment.
Halogenated hydrocarbon
solvents for example:
methylene chloride and
1,1,1,-Trichloroethane are not
chemically compatible with the
aluminum that might be used
in many system components.
The chemical reaction
caused by these solvents
reacting with aluminum can
become violent and lead to an
equipment explosion.

OPERATION
The DR-1TM Plastic Regulator is designed to provide remote
controluidregulationforautomaticcoatingapplications.
Theregulatorfeaturestwoindependentlycontrollableow
pressurerangesfromtheuidoutputport.Thehighow
rangeportaccomm-odateshigheruiddeliveriesandmin-
imalcolorchangetimes.Thelowerowrangesprovide
preciseuiddeliverycontrol.Therearesevenlowerrange
models available (1:1, 1:2, 1:3, 1:4, 1:6, 1:8, and 1:10)
whichcanbeselectedbasedontherequireduidowrate.
Separate pilot signals modulate each of the regu-lator’s two
diaphragms to control the amount of paint being delivered
from the regulator to the spray applicator. These pilot
signals can be controlled manually or automatically with
the AdaptaFlowTM5000,closedloopowcontrolsystem.
Because of the regulator’s dual range capabilities, it provides
theuserexibilityofselectingeitherthehighowrangeor
thelowowrange.Differentcoatingmaterialviscosities
and quick color change requirements may necessitate the
use of both ranges. If color change time is not a factor
or if material viscosity remains relatively constant, either
portmaybeuseddependingonowraterequirements.
All regulators, regardless of ratio designation, have the
highowport.
Thelowow(i.e.1:2,1:4,etc.)portprovidesalower,more
preciseowresponsecurve.Fluidoutput,asaresult,is
less likely to be affected by pilot signal errors. An increase
in the ratio (i.e. from 1:2 to 1:4) provides a lower slope in the
ow/airsignalpressurecurve,but,morepreciseresponse
curve. This same increase in ratio, however, will reduce
ow capacity and should be considered when selecting
the proper regulator ratio.
The following factors must then be considered when se-
lectingtheregulatorratiorequiredforproperuidcontrol:
• Fluid tubing inside diameter (ID) and length
• Fluid feed tube inside diameter (ID) and length
• Fluid viscosity
• Fluid input pressures
Preliminary testing will determine which regulator ratio
should be used. If conditions change after installation
whichrequireadifferentlowowratio,thisregulatorcan
be altered easily by replacing the existing ratio spacer ring
and upper retainer with the desired ratio (ratio designation
is etched on the side of the spacer ring).

PRELIMINARY PROCEDURES
Prior to removing the regulator for service or repair, perform
the following:
1. Ifpossible,ushtheregulatorwithsuitablecleaning
solvent.
2. Turn the uid and air "OFF" to the regulator and
disconnecttheairanduidlinesfromtheregulator.
3. Remove the regulator for service.
DISASSEMBLY PROCEDURES
(Refer to Figure 1)
TOOLS REQUIRED
• 3/4-inch Open End Wrench
 •AdjustableWrench
• Screwdriver
• Repair Kit, 73913-01
1. Remove Item 4 (8-screws) holding the regulator as-
sembly together with the screwdriver.
2. Remove Item 1 (cap), Item 9 (diaphragm), spacer ring
assembly and the lower housing assembly.
3. With screwdriver, remove Item 15 (screw) from the
spacer ring assembly.
4. Separate Item 6 (lower diaphragm retainer), Item 10
(o-ring), Item 8 (lower diaphragm), Item 16 (bleed
spacer), Item 14 (center diaphragm) and Item 5
(upper diaphragm retainer) from the spacer ring
assembly.
5. With the 3/4-inch open-end wrench, remove Item
13 (retaining plug), Item 12 (spring) and Item 11
(regulating needle) from Item 3 (lower housing).
6. Remove Item 11 (regulating seat) and Item 10
(o-ring) from the lower housing assembly.
7. Clean all metal parts with suitable cleaning solvent.
DO NOT use solvent on the diaphragms or o-rings.
Unless replacing the cap or spacer ring, it is NOT
necessarytoremovetheairttings.
The regulating needle and seat are a matched
set with matching serial numbers. Care must be tak-
en to not use needles and seats with non-matching
serialnumbersasuidleakagemayoccur.Ifeither
component needs to be replaced, a new matched
set must be used.
When separating parts it may be necessary to
use a small screwdriver. Care should be taken to
NOT damage the plastic components. Damage of
these parts may cause leakage.
Care MUST be taken while cleaning the coated
parts of the regulator to prevent scratching.

ASSEMBLY PROCEDURES
(Refer to Figure 1)
1. Place Item 10 (o-ring) in the slot on Item 6 (lower
diaphragm retainer).
2. Place Item 8 (lower diaphragm) on the lower diaphragm
retainer with the side of the diaphragm contacting the
retainer (o-ring side).
3. Stack the following parts on the lower diaphragm, in
the following order:
• Item 7 - Center Diaphragm Retainer
• Item 16 - Bleed Spacer
• Item 14 - Center Diaphragm
• Item 5 - Upper Diaphragm Retainer
• Item 15 - Screw
4. Ensure that clearance holes in Items 8 and 14
(diaphragms) and Item 16 (bleed spacer) are aligned
properly and tighten Item 15 (screw). Use adhesive
222 on screw threads. Set this assembly aside.
5. Place lower housing on table with bottom threaded
openingfacing"UP".
6. Insert Item 10 (o-ring) and Item 11 (regulating seat) into
the lower housing. The beveled side of the regulating
seatmustbe"UP".

Rotate the spacer ring, without rotating the diaphragm
assembly, so that the alignment mark in the spacer
ring is directly over the correct letter stamped on Item
3 (lower housing). (See Figure 2 for correct tting
alignment based on your applicator.)
12. Place Item 9 (diaphragm) on Item 2 (spacer ring) and
align holes.
13. Place Item 1 (cap) on diaphragm. Rotate the cap,
without rotating the diaphragm assembly, so that
the alignment mark is in line with the mark on Item 2

TEST PROCEDURES
(Refer to Figure 1)
After repair is complete, test the regulator in the
following manner:
1. Setairanduidregulatorstozeroandattachairand
uidlinestotheregulator.
2. Gradually increase air pressure to the regulator to 80
psi, visually checking for leaks. Tighten Item 4 (screws)
if leakage occurs.
PREVENTIVE MAINTENANCE
1. Rebuild with 73913-01, repair kit, and 74160-00, needle
and seat, at 6 months minimum, 12 months maximum.
2. Retorque eight (8) screws at the following intervals:
• 2 days after rebuild
• Immediately before installation
• 6 month intervals
3. Set air regulator to zero. Gradually increase uid
