*Model 248842 is designed for remote feed pumps and a remote mix manifold. It does not include hoppers, mix

manifold, hose, or spray gun. Refer to manual 310794 for application layout.

Model 248842 is limited to 5000 psi (34.5 MPa, 345 bar) for use in “quick set” packages where heated hoses, whip hoses, and spray accessories are limited to 5000 psi (34.5 MPa, 345 bar). If all your downstream components are rated for 7000 psi (48 MPa, 483 bar), you can replace the standard relief valve with relief valve

113498.

Warnings

The following general warnings are related to the safe setup, use, grounding, maintenance, and repair of this equipment. Additional more specific warnings may be found throughout the text 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 equipment and conductive objects in 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 fire extinguisher in the work area.

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.

SKIN INJECTION HAZARD

High-pressure fluid from gun, 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 gun at anyone or at any part of the body.

• Do not put your hand over the spray tip.

• Do not stop or deflect leaks with your hand, body, glove, or rag.

• Do not spray without tip guard and trigger guard installed.

• Engage trigger lock when not spraying.

• Follow Pressure Relief Procedure in this manual, when you stop spraying and before cleaning, checking, or servicing equipment.

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.

Warning

EQUIPMENT MISUSE HAZARD

Misuse can cause death or serious injury.

• Do not exceed the maximum working pressure or temperature rating of the lowest rated system com-

ponent. 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.

• Check equipment daily. Repair or replace worn or damaged parts immediately.

• Do not alter or modify equipment.

• For professional use only.

• Use equipment only for its intended purpose. Call your Graco distributor for information.

• Route hoses and cables away from traffic areas, sharp edges, moving parts, and hot surfaces.

• Do not kink or overbend hoses or use hoses to pull equipment.

• Comply with all applicable safety regulations.

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.

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.

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

RECOIL HAZARD

Gun may recoil when triggered and cause you to fall and be seriously injured if you are not standing securely.

Overview

Usage

The Xtreme Mix can mix most two-component epoxy and urethane paints. Only Model 248842 is for use with “quick-setting” paints (those with a pot life of less than 15 minutes). Other models cannot be used with such paints without modification. Contact your distributor for information.

The Xtreme Mix is operated with the User Interface, Air Controls and Fluid Controls, described below and on page 9. Refer to F

IG. 1 and FIG. 2.

User Interface

The User Interface has 6 main interfaces.

1. Knob to select functions:

Icon Function

Spray: proportion and spray material

Run pump A: operate pump A independent

of pump B (priming, flushing) for 12 cycles Run pump B: operate pump B independent

of pump A (priming, flushing) for 12 cycles Batch Dispense: dispense proportioned

amounts of A and B Pump Test: dispense predetermined

amount of A and B to verify pump operation and metering

Cycle Counter: totalize A and B pump cycles

3. Stop button to terminate functions

4. Key switch to change ratio or reset pump cycle

counter

5. Display (five-digits) to view:

•Ratio

• Alarm codes

• Pump cycles

The display includes an alarm code label in English. See page 2 to order additional languages.

6. Data port allows for connection to a PC serial port

to download cycle count, operation, ratio setting, and error alarm data.

WARNING

The PC must be in a non-hazardous location and a safety barrier must be installed between the PC and Xtreme Mix unit. See Xtreme Mix software manual.

Overview

Air Controls

A. Main air shutoff valve (bleed-type) to shutoff all

air to Xtreme Mix (including controller power)

B. Supply air pressure gauge to monitor air pressure

to Xtreme Mix

A minimum air pressure supply of 50 psi (0.35 MPa, 3.5 bar) must be maintained for the Xtreme Mix to operate properly.

C. Pump air pressure regulator with gauge to adjust

and monitor pump air pressure

Push in regulator knob to lock setting. Be careful when pulling knob out to change setting as knob is removable. To reinstall, push knob to snap into place.
