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

•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.

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.

FIG. 1

Service

83A5413F

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.

FIG. 2

FIG. 3

Service

3A5413F 9

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).

•Route black and white wire (f) between

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.
