Warnings
WARNING
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 lowest 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.
• 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.
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 in the pump instruction manual included with your operating
system, 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.

Valve Assembly Installation
Grounding
The equipment must be grounded to reduce the risk
of static and electric shock by providing an escape
wire for the electric current due to static build up or in
the event of a short circuit.
Assemblies not originally
equipped with cycle pin
indicator pin/switch
1. Determine which valve section and side is the most
convenient location for the switch.
2. Disconnect the electrical system.
3. Relieve pressure. See Pressure Relief Procedure in
the pump instruction manual included with your
operating system.
NOTICE
Do not over torque. Excessive torque will cause
switch failure.
4. Remove piston plug and discard.
5. Install the appropriate proximity switch into the piston chamber using the supplied seal/gasket. For
MS and MH valve sections, torque to 6-8 ft-lb (8 10.8 N•m) for o-ring seal; 10 ft-lb (13.6 N•m) for
gasket seals. For MX and MGO torque adapter to
25-30 ft-lb (33.9 - 40.7 N•m) and the switch to 6-8
ft-lb (8 - 10.8 N•m).
6. Connect the electrical system.
NOTICE
Do not reuse gasket. If switch is removed for any reason, replace with new gasket, part no. 557717.
Assemblies equipped with cycle
pin indicator/electrical
micro-switch
(Two options: Method A or Method B)
Method A: Installation in any piston
chamber not occupied by the cycle pin
indicator
1. Determine which valve section and side is the most
convenient location for the switch.
2. Disconnect the electrical system.
3. Relieve pressure. See Pressure Relief Procedure in
the pump instruction manual included with your
operating system.
4. Remove the piston plug. (Do not discard plug if
removing the cycle indicator pin. It is reinstalled in
step 6e.)
5. Install the appropriate proximity switch into the
piston chamber using the supplied seal/gasket. For
MS and MH valve sections, torque to 6-8 ft-lb (8 10.8 N•m) (for o-ring seal; 10 ft-lb (13.6 N•m) for
gasket seals. For MX and MGO torque adapter to
25-30 ft-lb (33.9 - 40.7 N•m) and the switch to 6-8
ft-lb (8 - 10.8 N•m).
NOTICE
Do not over torque. Excessive torque will cause
switch failure.
NOTICE
Do not reuse gasket. If switch is removed for any reason, replace with new gasket, part no. 557717.
6. Either leave the cycle indicator pin installed for
visual indication of cycle or remove as follows:
a. Unscrew cycle indicator body from valve and
discard.
b. Grasp indicator pin and pull pin/piston assembly out of the feeder.

Valve Assembly Installation
NOTICE
Piston is a ground part and all caution must be taken
to avoid nicking, scratching or contaminating this
part or the feeder piston bore.
Wiring Instructions
c. Remove the indicator pin by sliding it through
the slot on models equipped with this arrangement (MS and late model MX type) or drive out
cross pin using a brass rod (old MX type).
The equipment must be grounded to reduce the risk
of static and electric shock by providing an escape
wire for the electric current due to static build up or in
the event of a short circuit.
d. Discard the pin.
In order to make proper electrical connections, a “Brad
Harrison” style connector cable must be used. The following connector cables are available:
e. Carefully insert piston back into the bore.
f.
Plug the hole with piston plug removed in step
4. Torque to 12 ft-lb (16.3 N•m) for MSP, 35
ft-lb (47.5 N•m) for MX.
7. Make electrical connection.
Method B: Replacing existing cycle
indicator pin/switch
1. Determine which valve section and side is the most
convenient location for the switch.
2. Relieve pressure. See Pressure Relief Procedure in
the pump instruction manual included with your
operating system.
NOTICE
Do not over torque. Excessive torque will cause
switch failure.
3. Remove the existing cycle indicator pin/switch.
4. Reverse piston so the proximity switch does not
sense slot end of piston.
5. Install the appropriate proximity switch into the piston chamber using the supplied seal/gasket. For
MS and MH valve sections, torque to 6-8 ft-lb (8 10.8 N•m) for o-ring seal; 10 ft-lb (13.6 N•m) for
gasket seals. For MX and MGO torque adapter to
25-30 ft-lb (33.9 - 40.7 N•m) and the switch to 6-8
ft-lb (8 - 10.8 N•m).
