E-Flo Plus Electric Circulation Pumps

Check your pump’s identification plate (ID) for the 6-digit part number of your

pump. Use the following matrix to define the construction of your pump, based

on the six digits. For example, Pump Part No. EP2160represents electric

power (E), pump (P), 230/460V motor (2), sensor circuit installed (1), and 2000

cc Maxlife lower (6). The last digit (0) is unassigned. To order replacement

parts, see the Repair-Parts manual 311594.

Maximum Working Pressure and Pump Operational Limits

1000 cc Pumps: 460 psi (3.22 MPa, 32.2 bar) Maximum Working Pressure

1500 cc Pumps: 330 psi (2.31 MPa, 23.1 bar) Maximum Working Pressure

2000 cc Pumps: 250 psi (1.75 MPa, 17.5 bar) Maximum Working Pressure

See Technical Data, page 21, for pump operational limits.

Approvals

The E-Flo Plus Pump meets requirements of the follow-

ing approval agencies.

Refer to the individual components for other specific

hazardous location listings.

Warnings

The following warnings are for the setup, use, grounding, maintenance, and repair of this equipment. The exclama-

tion point symbol alerts you to a general warning and the hazard symbol refers to procedure-specific risk. Refer back

to these warnings. Additional, product-specific warnings may be found 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. 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 arc).

• 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.

• Ground all equipment in the work area. See Grounding instructions.

• Use only grounded hoses.

• Hold gun firmly to side of grounded pail when triggering into pail.

• If there is static sparking or you feel a shock, stop operation immediately. Do not use equipment

until you identify and correct the problem.

• Keep a working fire extinguisher in the work area.

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 Data in all equipment manuals.

• Use fluids and solvents that are compatible with equipment wetted parts. See Technical Data in all

equipment manuals. Read fluid and solvent manufacturer’s warnings. For complete information

about your material, request MSDS forms from distributor or retailer.

• Check equipment daily. Repair or replace worn or damaged parts immediately with genuine manu-

facturer’s replacement parts only.

• Do not alter or modify equipment.

• 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.

ELECTRIC SHOCK HAZARD

Improper grounding, setup, or usage of the system can cause electric shock.

• Turn off and disconnect power at main switch before disconnecting any cables and before servicing

equipment.

• Connect only to grounded power source.

• All electrical wiring must be done by a qualified electrician and comply with all local codes and

regulations.

Warnings

311592B 5

PRESSURIZED EQUIPMENT HAZARD

Fluid from the gun/dispense valve, leaks, or ruptured components can splash in the eyes or on skin and

cause serious injury.

• Follow Pressure Relief Procedure in this manual, when you stop spraying and before cleaning,

checking, or servicing equipment.

• Tighten all fluid connections before operating the equipment.

• Check hoses, tubes, and couplings daily. Replace worn or damaged parts immediately.

MOVING PARTS HAZARD

Moving parts can pinch or amputate fingers and other body parts.

• Keep clear of moving parts.

• Do not operate equipment with protective guards or covers removed.

• Pressurized equipment can start without warning. Before checking, moving, or servicing equipment,

follow the Pressure Relief Procedure in this manual. Disconnect power or air supply.

TOXIC FLUID OR FUMES HAZARD

Toxic fluids or fumes can cause serious injury or death if splashed in the eyes or on skin, inhaled, or

swallowed.

• Read MSDS’s to know the specific hazards of the fluids you are using.

• Store hazardous fluid in approved containers, and dispose of it according to applicable guidelines.

• Always wear impervious gloves when spraying or cleaning equipment.

PERSONAL PROTECTIVE EQUIPMENT

You must wear appropriate protective equipment when operating, servicing, or when in the operating

area of the equipment to help protect you from serious injury, including eye injury, inhalation of toxic

fumes, burns, and hearing loss. This equipment includes but is not limited to:

• Protective eyewear

• Clothing and respirator as recommended by the fluid and solvent manufacturer

•Gloves

• Hearing protection

BURN HAZARD

Equipment surfaces and fluid that’s heated can become very hot during operation. To avoid severe

burns, do not touch hot fluid or equipment. Wait until equipment/fluid has cooled completely.

Power Supply Requirements

See TABLE 1 for power supply requirements. The system

requires a dedicated circuit protected with a 20 A circuit

breaker.

Power Disconnect Switch

See FIG. 1 on page 7. Install a power disconnect switch

(E) in the non-hazardous area. This switch must shut off

and lock-out all electric power to the system.

Hazardous Area Cabling and

Conduit Requirements

(Explosion Proof)

All electrical wiring in the hazardous area must be

encased in Class I, Division I, Group C and D approved

explosion-proof conduit.

Wire passages from the hazardous to the non-hazard-

ous area must be secured by explosion-proof seal fit-

tings (L).

Increased Safety (European)

Use appropriate cables, connectors, and cable glands

rated for ATEX II 2 G. Follow all National and Local elec-

tric codes.

288036 Power Module

The 288036 Power Module transforms the high voltage

power supply to a 24 Vdc input for the pump sensor cir-

cuit. See manual 311608 for further information.

See FIG. 1 on page 7. Install the power module (G) in

the non-hazardous area.

See FIG. 2 Electrical Schematic for module wiring con-

nections.

Improper wiring may cause electric shock or other

serious injury if work is not performed properly. Have

a qualified electrician perform any electrical work. Be

sure your installation complies with all National, State

and Local safety and fire codes.
