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
FIRE AND EXPLOSION HAZARD
Flammable fumes, such as solvent and paint fumes, in work area can ignite or explode. Paint or
solvent flowing through the equipment can cause static sparking. To help prevent fire and explosion:
• Use equipment only in well-ventilated area.
• Eliminate all ignition sources; such as pilot lights, cigarettes, portable electric lamps, and plastic
drop cloths (potential static sparking).
• Ground all equipment in the work area. See Grounding instructions in your pump manual.
• Keep work area free of debris, including solvent, rags and gasoline.
• Do not plug or unplug power cords, or turn power or light switches on or off when flammable fumes
are present.
• Use only conductive grounded fluid lines.
•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.
Static charge may build up on plastic parts during cleaning and could discharge and ignite flammable
vapors. To help prevent fire and explosion:
• Clean plastic parts only in well-ventilated area.
• Do not clean with a dry cloth.

Warnings
4 3A8861C

• Turn off and disconnect power at main switch before disconnecting any cables and before servicing
or installing equipment.
• Connect only to grounded power source.
• All electrical wiring and repairs must be done by a qualified electrician and comply with all local
codes and regulations.
• Do not expose to rain. Store indoors.
Ordinary Locations Pumps (cord and plug connection)
This equipment must be grounded. Improper grounding, setup, or usage of the system can cause
electric shock.
• Turn off and disconnect power cord before servicing equipment.
• Connect only to grounded electrical outlets.
• Only use 3-wire extension cords for 2-phase models. Only use 4-wire extension cords for 3-phase
models.
• Ensure ground prongs are intact on power and extension cords.
• Do not expose to rain. Store indoors.
• Wait five minutes after disconnecting power cord before servicing.
PRESSURIZED EQUIPMENT HAZARD
Fluid from the equipment, leaks, or ruptured components can splash in the eyes or on skin and cause
serious injury.
• Follow the Pressure Relief Procedure in your pump manual when you stop spraying/dispensing
and before cleaning, checking, or servicing equipment.
• Tighten all fluid connections before operating the equipment.
• Check fluid lines and connections daily. Replace worn or damaged parts immediately.
WARNING

Warnings
3A8861C 5
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

• Turn off all equipment and follow the Pressure Relief Procedure in your pump manual when
equipment 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 fluid lines, cords, and cables away from traffic areas, sharp edges, moving parts, and hot
surfaces.
• Do not kink or over-bend fluid lines, cords, or cables. Do not use fluid lines, cords, or cables to pull
equipment.
• Keep children and animals away from work area.
• Comply with all applicable safety regulations.
BURN HAZARD
Equipment surfaces and fluid that is heated can become very hot during operation. To avoid severe
burns:
• Do not touch hot fluid or equipment.
PERSONAL PROTECTIVE EQUIPMENT
Wear appropriate protective equipment when in the work area to help prevent serious injury, including
eye injury, hearing loss, inhalation of toxic fumes, and burns. Protective equipment includes but is not
limited to:
• Protective eyewear, and hearing protection.
• Respirators, protective clothing, and gloves as recommended by the fluid and solvent
manufacturer.

Installation
Prepare the Pump
Always complete the following procedure before
performing any service or repair to the equipment.
1. Relieve the pressure. Follow the Pressure Relief
Procedure in your related pump manual. See
Related Manuals, page 2.
2. Verify that the pump is turned off and power to the
system is disconnected before performing any
service or repair procedure.
Install the Leak Sensor
See FIG. 3–FIG. 4.
Required Tools:
• 7/8 in. open-end wrench
• 3/8 in. hex wrench
• 3/4 in. open-end wrench (for pumps certified for
use in Ordinary Locations only)
Remove the Leak Sensor
If a leak sensor is currently installed, remove the current
leak sensor before installing the new leak sensor.
1. Follow Prepare the Pump, page 7.
2. Remove the control cover. See your related motor
manual. See Related Manuals, page 2.
3. Disconnect the leak sensor wire (A) from the port in
the control housing (S). See Electrical
Schematics, page 13.
4. Pumps Certified for Use in Ordinary Locations
only: Loosen the fitting (B) behind the leak sensor
