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.
PERSONAL PROTECTIVE EQUIPMENT
You must wear proper 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: and
hearing loss;. This equipment includes but is not limited to:

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.
