e or

destruction if

ou do not follow instructions.

A note indicates additional helpful information.

WARNING

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 medical attention.

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

• Tighten all fluid connections before operating the equipment.

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

sure hose cannot be recoupled; replace the entire hose.

FIRE AND EXPLOSION HAZARD

• 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 and plastic drop cloths (potential static

arc).

• Do not plug or unplug power cords or turn lights on or off when flammable fumes are present.

• Keep the work area free of debris, including solvent, rags, and gasoline.

• Ground equipment and conductive objects.

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

equipment until you identify and correct the problem.

Warning

309525C 3

ELECTRIC SHOCK HAZARD

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

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

lations.

• Connect only to grounded power source.

• Turn off and disconnect power at the main switch before disconnecting any cables and before servic-

ing equipment.

EQUIPMENT MISUSE HAZARD

Misuse can cause serious injury or death.

• For professional use only.

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

• Read manuals, warnings, tags, and labels before operating equipment. Follow instructions.

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

• Do not alter or modify equipment. Use only Graco parts and accessories.

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

component. See page 14 and the Technical Data for all system components.

• 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.

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

• Comply with all applicable safety regulations.

BURN HAZARD

This equipment is used with heated fluid, which can cause equipment surfaces to become very hot. To

avoid severe burns:

• Do not touch hot fluid or equipment.

• Allow equipment to cool completely before touching it.

• Wear heat protective gloves and take special care if fluid temperature exceeds 110° F (43° C).

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 Material Safety Data Sheets (MSDS) 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.

Installing the Kit

Refer to FIG. 1 and FIG. 2

1. Mount pump (16) on the Xtreme Mix cart (D) using

the bracket (21), lockwashers (4), and nuts (2).

2. Mount VISCON HP heater (B-ordered separately)

on the cart using screws and lockwashers (A) sup-

plied with the heater, and the bracket (8), screws (9),

lockwashers (19), and nuts (20) supplied with the

kit.

3. Connect nipple (22) and air regulator (7) to Husky

716 pump. Connect 100 psi (0.7MPa, 7 bar) air sup-

ply to the air regulator using air tubing (5), and air fit-

ting (3). Refer to Husky 716 manual if needed.

4. Wire VISCON HP heater (B) to your voltage supply.

Follow wiring procedure in the VISCON HP manual.

5. Connect elbow (24), fitting (23), o-ring (17), and

reservoir tank (6) to Husky 716 pump (16). On other

side of pump, install bushing (11) and tube fitting

(10).

6. Connect tube fittings (12, 13) to the VISCON HP

heater (B).

7. Interconnect reservoir tank (6), Husky 716 pump

(16), VISCON HP heater (B), and heated hose

(C-FIG. 1), using tubing (1), tube inserts (15) and fit-

tings (10, 12, 13, 14) as described below.

a. Using tubing cutter (19), cut tubing (1) squarely

to desired lengths.

b. Insert tube inserts (15) in tubing (1) ends to

avoid leakage.

c. Insert tubing (1) through the back of the nut in

each of the plastic fittings (10, 12, 13, 14) until

the tube stops. Tighten the nut hand tight, then

tighten it 1-1/2 to 2 turns with a wrench.

Connecting Additional Hose Lengths

Up to six 50 ft. (15.2 m) sections of heated hose can be

attached for a maximum total length of 300 ft. (91.4 m).

1. Remove plastic u-turn fittings at the end of the

heated hose assembly. See FIG. 1.

2. Connect the next length of hose, using union fittings

supplied with the hose. Follow fitting assembly pro-

cedure in steps 7a-7c, above.

3. Tubes are color coded. Connect like colors.

The air regulator (7) controls pump (16) pressure.

WARNING

All wiring must be done by an electrician. See warn-

ings, page 2.

To ensure a leak-proof seal, use PTFE®tape on

all pipe thread connections.

Fitting nuts may need retightening as the system

reaches normal operating temperatures.

Operation

10 309525C

Operation

Refer to FIG. 2

1. Select fluid to use for heating circulation.

• If ambient temperatures (storage or operating)

are below 40° F (4.4° C), a 50% water and 50%

antifreeze mixture is recommended.

• If ambient temperatures are above 40° F (4.4°

C), water alone is okay.

2. Pour heating circulation fluid into the reservoir tank

(6), increase air regulator (7) pressure, and cycle

the pump (16). Continue to pour fluid into tank until

all air is purged.

3. Fill reservoir tank (6) about half full. Do not overfill;

fluid needs room to expand as the hose heats.

4. Set the flow rate of the circulation fluid to 2 gpm (7.6

lpm) by adjusting the pump’s air regulator (7) until

the pump cycles at 50 cycles/min. Do not use a

higher flow rate as doing so will decrease system

performance and pump life. Never exceed the

hose’s 95 psi (0.6 MPa, 6.6 bar) maximum working

pressure rating.

5. Adjust the heater thermostat to the desired hose

temperature. The setting should be about 10° F

(6° C) higher than the desired paint temperature.

Never exceed the hose’s 180° F (82° C) maximum

temperature rating.

WARNING

Read the warnings, page 2, before operating the

equipment.

Detailed diaphragm pump operating instructions

are in Husky 716 manual.

Each 50 ft. (15.2 m) heated hose section holds

approximately 1.25 gal. (4.7 liters) of fluid.

If the hose is not being used for more than one

hour, shut off VISCON HP heater and Husky 716

pump to lengthen heater life.
