Warnings
The following warnings are for the setup, use, grounding, maintenance, and repair of this
equipment. The exclamation point symbol alerts you to a general warning and the hazard
symbols refer to procedure-specific risks. When these symbols appear in the body of this
manual or on warning labels, refer back to these Warnings. Product-specific hazard symbols
and warnings not covered in this section may appear throughout the body of this manual where
applicable.
WARNING
SKIN INJECTION HAZARD
High-pressure fluid from dispensing device, hose leaks, or ruptured components
will pierce skin. This may look like just a cut, but it is a serious injury that can result
in amputation. Get immediate surgical treatment.
•Do not point dispensing device at anyone or at any part of the body.
•Do not put your hand over the fluid outlet.
•Do not stop or deflect leaks with your hand, body, glove, or rag.
•Follow the Pressure Relief Procedure when you stop dispensing and before
cleaning, checking, or servicing equipment.
•Tighten all fluid connections before operating the equipment.
•Check hoses and couplings daily. Replace worn or damaged parts immediately.
EQUIPMENT MISUSE HAZARD
Misuse can cause death or serious injury.
•Do not operate the unit when fatigued or under the influence of drugs or alcohol.
•Do not exceed the maximum working pressure or temperature rating of the low-
est rated system component. See Technical Specifications in all equipment
manuals.
•Use fluids and solvents that are compatible with equipment wetted parts. See
Technical Specifications in all equipment manuals. Read fluid and solvent
manufacturer’s warnings. For complete information about your material, request
Safety Data Sheets (SDSs) from distributor or retailer.
•Turn off all equipment and follow the Pressure Relief Procedure when equip-
ment is not in use.
•Check equipment daily. Repair or replace worn or damaged parts immediately
with genuine manufacturer’s replacement parts only.
•Do not alter or modify equipment. Alterations or modifications may void agency
approvals and create safety hazards.
•Make sure all equipment is rated and approved for the environment in which you
are using it.
•Use equipment only for its intended purpose. Call your distributor for information.
•Route hoses and cables away from traffic areas, sharp edges, moving parts, and
hot surfaces.
•Do not kink or over bend hoses or use hoses to pull equipment.
•Keep children and animals away from work area.
•Comply with all applicable safety regulations.

Warnings
43A5413F
FIRE AND EXPLOSION HAZARD
When flammable fluids are present in the work area, such as gasoline and wind-
shield wiper fluid, be aware that flammable fumes can ignite or explode. To help
prevent fire and explosion:
•Use equipment only in well-ventilated area.
•Eliminate all ignition sources, such as cigarettes and portable electric lamps.
•Ground all equipment in the work area.
•Keep work area free of debris, including rags and spilled or open containers of
solvent and gasoline.
•Do not plug or unplug power cords or turn lights on or off when flammable fumes
are present.
•Use only grounded hoses.
•Stop operation immediately if static sparking occurs or you feel a shock.Do
not use equipment until you identify and correct the problem.
•Keep a working fire extinguisher in the work area.
PERSONAL PROTECTIVE EQUIPMENT
Wear appropriate protective equipment when in the work area to help prevent seri-
ous injury, including eye injury, hearing loss, inhalation of toxic fumes, and burns.
Protective equipment includes but is not limited to:
•Protective eye wear, and hearing protection.

Pressure Relief Procedure
Follow the Pressure Relief
Procedure whenever you see this
symbol.
1. Turn off power supply to the pump or
close fluid shut off valve (B).
2. Open nozzle.
3. Trigger the metered dispense valve into
a waste container to relieve pressure.
•Pulse meters require an authorized test
dispense within the Pulse Fluid
Management Software to enable the
trigger.
•SDP meters require a preset dispense
activation to enable the trigger.
•SDP meters with Pulse FC enabled
require an enabled dispense card to
authorize a dispense to enable the
trigger.
•SDM meter triggers are always enabled.
4. Open any bleed-type master air valves
and fluid drain valves in the system.
5. Leave the drain valve open until you are
ready to pressurize the system.
Battery Replacement
NOTE: The metered dispense valve does not
have to be taken out of service to replace the
batteries.
•Replace batteries with four AA, alkaline
batteries.
•Be sure to follow the correct polarity as
shown on the installation labels located
on either side of the metered dispense
valve when installing batteries in the
battery compartment (FIG. 2).
•Do not mix different types of batteries
together or old batteries with fresh
ones. Always replace all 4 batteries with
4, fresh, new AA batteries.
To change the battery:
1. Remove screws (36) from the battery
compartment cover (5).
2. Use a small, flat screwdriver to gently pry
the cover away from the metered
dispense valve housing on the bottom
side of the cover, near the extension
attachment as shown in FIG. 1.
3. Remove and separately recycle
batteries according to all applicable
regulations.
4. Install 4 new batteries. See labels on the
each side of the housing and FIG. 2 for
battery orientation.
This equipment stays pressurized until
pressure is manually relieved. To help
prevent serious injury from pressurized
fluid, such as skin injection, splashing fluid
and moving parts, follow the Pressure
Relief Procedure when you stop
dispensing and before cleaning, checking,
or servicing the equipment.

5. Replace cover (5) and screws (36).
Tighten screws hand tight. Do not
over-tighten screws(FIG. 3).
Bezel Replacement
Pulse Meters use Bezel Replacement Kit
26C287
SDP Meters use Bezel Replacement Kit
26C403
SDM Meters use Bezel Replacement Kit
26C484
NOTE: The metered dispense valve does not
have to be taken out of service to replace the
bezel.
Disassembly
1. Relieve pressure. See Pressure Relief
procedure, page 7.
2. Remove batteries. See Battery
Replacement, page 7.
3. Remove 4 screws (21) and o-rings (20)
and carefully lift bezel (19) off housing
(12) (FIG. 4).
NOTE: The solenoid (Pulse and SDP
Models only) and power will still be
connected to the bezel via the power
connections as shown in FIG. 5. Before
the bezel can be completely separated
from the housing, these connections
must be detached.

4. Detach the red and white solenoid
connection (a) (FIG. 5).Pulse and SDP
Models only.
5. Detach the black and red power
connection (b) (FIG. 5).
NOTE: Be careful not to disturb the white
button board ribbon cable taped to the
bezel housing if reusing the bezel (19).
Reassembly
1. Connect the black and red power wires
(b) (FIG. 5).
NOTE: Be careful not to disturb the white
button board ribbon cable taped to the
bezel housing.
2. Connect red and white solenoid wires (a)
(FIG. 5).Pulse and SDP Models only.
3. There are three wire groupings that must
be carefully routed inside the housing.
•Wrap the red and white solenoid wire (a)
around the solenoid (37) (FIG. 6). Pulse
and SDP Models only.
•Route the red and black power wires (b)
between the central valve boss (c) and
the battery compartment (d) and under
the foam retainer (FIG. 7).

the central valve boss (c) and gear cover
screws (e) (FIG. 8).
NOTE: This wire runs between the two
battery compartments.
FIG. 9 shows the inside of the housing with all
wires routed correctly.
4. Take care that the wires will not be
pinched between the bezel (19) and
housing (12) and between the green
printed circuit board and the gear cover
when securing the bezel to the housing.
5. Verify o-ring (20) is in place on housing
(12). Install bezel (19) to housing using
o-rings (20) and 4 screws (21). Tighten
screws securely.
6. Install batteries and battery cover. See
Battery Replacement, page 7.
7. Recalibrate the metered dispense valve.
See Calibrate the Metered Dispense
Valve instructions provided in the
appropriate Metered Dispense Valve
Installation and Operation manual.
8. Pulse Pro meters must be registered and
configured per instructions found in
PulseTM Metered Dispense Valve
manual.
SDP meters with Pulse FC enabled must
be configured per instructions found in
SDP8/SDP18 Preset Metered Dispense
Valve, Pulse FC Enabled manual.
