SAFETY WARNINGS
HIGH PRESSURE FLUID CAN CAUSE SERIOUS INJURY.
FOR PROFESSIONAL USE ONLY. OBSERVE ALL WARNINGS.
Read And Understand All Instruction Manuals Before Operating Equipment.
All ELECTRICAL WIRING should be performed only by trained and qualified personnel
in compliance with all local, state and national codes.
FLUID INJECTION HAZARD
General Safety
This equipment conducts very high fluid pressure. Spray from the gun,
leaks or ruptured components can inject fluid through your skin and into
your body and cause extremely serious bodily injury, including the need
for amputation. Also, fluid injected or splashed into the eyes or on the skin
can cause serious damage.
Trigger Guard
Never operate the gun with the trigger guard removed. This guard helps
prevent the gun from triggering accidentally if it is dropped or bumped.
Spray Tip Safety
NEVER point the spray gun at anyone or at any part of the body. NEVER
put hand or fingers over the spray tip.
Use extreme caution when cleaning or changing spray tips. If the spray
tip clogs while spraying, engage the gun safety latch immediately. ALWAYS follow the Pressure Relief Procedure and then remove the spray
tip to clean it.
ALWAYS follow the Pressure Relief Procedure, right, before cleaning
or removing the spray tip or servicing any system equipment.
NEVER wipe off build–up around the spray tip until pressure is fully relieved and the gun safety latch is engaged.
NEVER try to stop or deflect leaks with your hand or body.
Be sure equipment safety devices are operating properly before each
use.
Medical Alert––Airless Spray Wounds
If any fluid appears to penetrate your skin, get EMERGENCY MEDICAL
CARE AT ONCE. DO NOT TREAT AS A SIMPLE CUT. Tell the doctor
exactly what fluid was injected.
Note to Physician: Injection in the skin is a traumatic injury. It is important to treat the injury surgically as soon as possible. Do not delay
treatment to research toxicity. Toxicity is a concern with some exotic
coatings injected directly into the blood stream. Consultation with a
plastic surgeon or reconstructive hand surgeon may be advisable.
Spray Gun Safety Devices
Be sure all gun safety devices are operating properly before each use. Do
not remove or modify any part of the gun; this can cause a malfunction
and result in serious bodily injury.
Safety Latch
Whenever you stop spraying, even for a moment, always set the gun
safety latch in the closed or “safe” position, making the gun inoperative.
Failure to set the safety latch can result in accidental triggering of the gun.
Pressure Relief Procedure
Always relieve the fluid pressure in the heater, pump and hoses before checking or adjusting any component in the system. This is to
reduce the risk of serious bodily injury , including fluid injection,
splashing fluid in the eyes or on the skin, burns from contact with
hot metal parts or fluid, and electric shock.
1.
Engage the gun safety latch.
2.
Shut off the main power to the heater.
3.
Circulate the fluid for at least 10 minutes to cool the heated
fluid and heater.
4.
Shut off all air and fluid supplies.
5.
Disengage the gun safety latch. Maintaining firm metal–to–
metal contact between the gun and a grounded metal pail,
trigger the gun into the pail to relieve pressure. Engage the
gun safety latch.
6.
Open the system fluid drain valve, having a container ready
to catch the fluid.
EQUIPMENT MISUSE HAZARD
General Safety
System Pressure
Any misuse of the spray equipment or accessories, such as
overpressurizing, modifying parts, using incompatible chemicals and fluids, or using worn or damaged parts, can cause them to rupture and result
in fluid injection, splashing in the eyes or on the skin, or other serious bodily injury, or fire, explosion or property damage.
This heater has a 3000 psi (210 bar) MAXIMUM WORKING PRESSURE. DO NOT exceed the maximum working pressure of any component or accessory used in the system.
NEVER alter or modify any part of this equipment; doing so could cause it
to malfunction.
Be sure that all accessories you add to the system are properly rated to
withstand the maximum air and fluid working pressure and temperatures
of this system.
CHECK all spray equipment regularly and repair or replace worn or damaged parts immediately.
Always wear protective eyewear, gloves, clothing and respirator as recommended by the fluid and solvent manufacturer.
Heat causes fluid to expand. If fluid in the heated portion of your system is
trapped with no where to expand, it can cause a system rupture. resulting
in serious bodily injury and property damage. To reduce the risk of overheating the fluid, be sure your system has an adequate way to handle
heat expansion: Use the heater in a circulating system, OR provide an
over–temperature safety relief valve, OR provide adequate heat dissipation. Never install any shutoff device between the heater and gun. If you
are using a fluid regulator before the gun, never use it as a shutoff device.
NEVER install any fluid shut off device at the fluid outlet of the heater or
filter. Shutting off the fluid at the outlet may cause overheating and high
back pressure which can cause component rupture and result in serious
bodily injury.
Fluid Compatibility
BE SURE that all fluids and solvents used are chemically compatible with
the wetted parts shown in the Technical Data on the back cover. Always
read the fluid and solvent manufacturer’s literature before using them in
this heater.
HOSE SAFETY
ALL FLUID HOSES USED WITH A FLEXING MOTION MUST HAVE
SPRING GUARDS ON BOTH ENDS! The spring guards help protect
the hose from kinks or bends at or close to the coupling which can result
in hose rupture.
High pressure fluid in the hoses can be very dangerous. If the hose develops a leak, split or rupture due to any kind of wear, damage or misuse, the
high pressure spray emitted from it can cause a fluid injection injury or
other serious bodily injury or property damage.
NEVER use a damaged hose. Before each use, check the entire hose for
cuts, leaks, abrasion, bulging cover, or damage or movement of the hose
couplings. If any of these conditions exist, replace the hose immediately.
DO NOT try to recouple high pressure hose or mend it with tape or any
other device. A repaired hose cannot safely contain the high pressure
fluid.
HANDLE AND ROUTE HOSES CAREFULLY. Do not pull on hoses to
move equipment. Do not use fluids or solvents which are not compatible
with the inner tube and cover of the hose.
TIGHTEN all fluid connections securely before each use. High pressure
fluid can dislodge a loose coupling or allow high pressure spray to be
emitted from the coupling.
MOVING PARTS HAZARD
Never operate the hose when it is coiled. Doing so causes excessive
heat buildup which can result in hose rupture and cause serious bodily
injury; including fluid injection, and property damage.
Moving parts can pinch or amputate your fingers or other body parts.
KEEP CLEAR of moving parts when starting or operating the equipment.
Follow the Pressure Relief Procedure on page 2 before checking or
servicing any part of the system, to prevent it from starting accidentally.
FIRE OR EXPLOSION HAZARD
Static electricity is created by the high velocity flow of fluid through the
pump and hose. If every part of the spray equipment is not properly
grounded, sparking may occur, and the system may become hazardous.
Sparking may also occur when plugging in or unplugging a power supply
cord. Sparks can ignite fumes from solvents and the fluid being sprayed,
dust particles and other flammable substances, whether you are spraying indoors or outdoors, and can cause a fire or explosion and serious
bodily injury and property damage. Do not plug in or unplug any power
supply cords in the spray area when there is any chance of igniting fumes
still in the air.
If you experience any static sparking or even a slight shock while using
this equipment, STOP SPRAYING IMMEDIATELY. Check the entire system for proper grounding. Do not use the system again until the problem
has been identified and corrected.
Grounding
To reduce the risk of static sparking, ground the pump and all other spray
equipment used or located in the spray area. CHECK your local electrical
code for detailed grounding instructions for your area and type of equipment. BE SURE to ground all of this spray equipment:
1.
Pump: use a ground wire and clamp as shown in your separate
pump manual.
2.
Air hoses: use only grounded air hoses.
3.
Fluid hoses: use only grounded fluid hoses.
4.
Heater: by wiring to a properly grounded power supply through the
electrical connections. In a mobile installation, be sure the truck or
trailer is grounded to a true earth ground, also.
5.
Air compressor or hydraulic power supply: follow manufacturer’s
recommendations.
6.
Spray gun: grounding is obtained through connection to a properly
grounded fluid hose and pump.
7.
Object being sprayed: according to your local code.
8.
All solvent pails used when flushing, according to local code. Use
only metal pails, which are conductive, placed on a grounded surface. Do not place the pail on a nonconductive surface, such as paper or cardboard, which interrupts the grounding continuity.
9.
To maintain grounding continuity when flushing or relieving pressure, always hold a metal part of the gun firmly to the side of a
grounded metal pail, then trigger the gun.
Electrical Wiring
All electrical wiring should be performed only by trained and qualified personnel in compliance with all local, state and national codes.
Never operate with covers removed. Conductors used for the supply
connection shall be suitable for at least 105) C (221) F).
This heater has a surface temperature code (identification code) of T3C,
indicating a maximum external (surface) temperature rating of 200) C
(392) F) in accordance with Article 500 – Hazardous Locations – of
NFPA 70 National Electrical Code and/or Section 18 – Hazardous Locations – of Part 1 of the Canadian Electrical Code. See and comply with the
requirements of these and similar codes as to the proper location of the
heater.
Flushing Safety
Reduce the risk of fluid injection injury, static sparking, or splashing by
following the specific flushing procedure given on page 8 of this manual.
Follow the Pressure Relief Procedure on page 2, and remove the spray
tip before flushing. Hold a metal part of the gun firmly to the side of a metal
pail and use the lowest possible fluid pressure during flushing.
IMPORTANT

WARNING
Heat causes fluid to expand. If fluid in the heated
portion of your system is trapped with no where to
expand, it can cause a system rupture. A system
rupture can result in serious bodily injury and property damage. Be sure your system has an adequate
way to handle heat expansion.
1. Use flexible hoses between the heater and gun.
2. OR, install a properly sized accumulator downstream from the heater.
3. OR, install a pressure relief valve (P – see the
installation drawing above), pre–set to relieve
pressure when it exceeds the system’ s maximum working pressure.
4. Never install any shutof f device between the
heater and gun. If you are using a fluid regulator
before the gun, never use it as a shutoff device.
INSTALLATION
Mounting the Heater
The Typical Installation shown above is only a guide to
setting up a basic, heated, circulating system. Contact
your Graco representative for assistance in designing a
system to suit your needs.
Use 1/4 in. diameter mounting screws (P) to install the
heat insulators (19) on each side of the bolt holes in the
heater housing (Q). See Fig 1. Mount the heater near the
object to be sprayed, but outside the spray area. Be sure
the surface on which you mount the heater can support
the weight of the heater, filters, hoses and fluid. See the
DIMENSIONAL DRAWING on page 15 and TECHNICAL DATA on page 15.
Q
Wiring
Remove the heater cover (20). Connect the electric wires
of the circuit to the heater leads (R & S) with connectors
(T). Crimp the terminal (24) onto the ground wire (U) of
the circuit and connect to the heater ground connection
screw (5). See Fig 2.
WARNING
All wire nuts used for heater connections must be
rated at 150 C or higher . NEVER use wire nuts
rated less than 150 C; they cannot withstand the
heat generated.
NOTE: Be sure your voltage supply agrees with the
heater voltage. The 120 volt heater draws 18
amps, and the 240 volt heater draws 9 amps.

Install a fluid shutof f valve (G) UPSTREAM from the
heater. This is used to isolate the heater when it requires
servicing. DOWNSTREAM, install a fluid filter and drain
valve (E). The filter removes sediment that may have collected in the heater, which could clog the spray gun.
24
Connect Hoses
Connect the fluids lines to the 1/2 npt(f) inlet and outlet of
the heater. See the TYPICAL INSTALLATION, on page
4.
To minimize heat loss, fluid lines should be insulated
when they are especially long if the environment is cool.

OPERATION
Flushing
This heater was factory tested with a lightweight oil. Use
low pressure and a compatible solvent to flush the system. While the system is pressurized, check it carefully
for leaks at all fluid connections. Pump out the solvent,
relieve the system pressure and tighten any leaking connections. Prime the system and check to be sure that all
leaks have stopped.
Priming the System
Pump the fluid until all air has been purged from the system, to permit proper heating and spraying. In a completely closed, circulating system, use a director valve (L)
attached to the pump intake to purge the system. See the
TYPICAL INSTALLATION drawing.
Setting Heater Controls
NOTE: The knob settings for Series E and older
Vis–Con heaters will dif fer from Series F
heaters (covered in this manual). It’s important
that you take this into consideration when
setting the heaters. Refer to the charts which
illustrate the difference.

Stop the pump, set the control knob (V) at 4 or 5 (trial setting) and let the heater warm up for about 10 minutes.
See Fig 4.
Adjusting for Spraying
Start the pump and check the fluid flow through the gun.
Readjust the control knob setting, if necessary, to obtain
the proper temperature for spraying.
In a Hydra–Sprayr system with a tip installed in the gun,
adjust the pump speed (use the pump air regulator) to the
lowest fluid pressure that will completely atomize the
fluid. In a circulating system, adjust the back pressure
valve also.
OPERATION
Determining the Proper Fluid Temperature
5. Subtract the lowest viscosity reading from the highest one. Multiply that result by 0.90. Subtract the new
result from the highest viscosity reading. Find this
number on your temperature and viscosity records.
This the temperature to use in your Under–Boil system.
CAUTION
Use the lowest temperature setting needed, for
maximum heater life. Operating the heater at its
highest setting – over 82) C (180) F) – for long
periods of time decreases the heater life.
Higher than necessary temperatures also cause the
fluid to dry out, resulting in a poor finish and clogging
the heater.

Effect Of Temperature In Reducing Two Fluids To A Sprayable Viscosity
The chart in Fig 6 shows the effect of temperature in reducing two fluids to a sprayable viscosity – in the range of 20 to 34
seconds using a No. 2 Zahn cup.
Notice that temperature has more of an effect on high solid fluids than on thin enamels. That is, for the same 10d temperature
rise, more viscosity reduction occurs in
the high solid fluid than the enamel. This
shows that high solid fluids are “temperature sensitive”, which needs to be taken
into consideration when planning your
system.

filters the fluid thoroughly . Always relieve system
pressure first, and cool the fluid, if possible. If not
possible wear protective eyewear and gloves to protect yourself from possible burns.
V
2. Flush the heater often enough to prevent a buildup of
dried sediment in it.
WARNING
9
Before flushing, always shut of f the main power to
the heater. Circulate the fluid through the system for
at least 10 minutes to cool the fluid and heater. This
reduces the risk of serious bodily injury from burns.
CAUTION
Clogged fluid passages can be very dif
ficult to
clean. They also reduce heating efficiency, flow rate
and pressure. To prevent clogged passages, do not
overheat or dry out the fluid, and flush frequently, including whenever the system or heater is not in use.
7
Fig 7
3. If the system runs dry, refill it immediately before fluid
can dry in it. Or flush the system thoroughly if you are
not going to use it immediately.
4. To drain the fluid from the heater, first relieve all system pressure. Cool the fluid if possible. Remove the
drain plug (7) in either end plate and drain the fluid
into a container. See Fig 7.
5. Shutdown.
CAUTION
When shutting down the system, turn the control
knob (V) to set point 1 and circulate the fluid for at
least 10 minutes before shutting off the pump. This
allows unheated fluid to gradually cool the heater
and heated fluid.
If Fluid Passages Are Clogged
Remove an end plate (21) and use a wire bottle brush to
clean. If necessary, use 1/2 in. (13 mm) hand reamer to
remove hard, caked deposits. When putting the end
plates back on, turn in all screws hand tight. Following the
sequence shown in Fig 8, torque each screw to 50 in–lb
(5.6 N.m), then torque them again, using the same sequence, to 170–180 in–lb (19.2–20.5 N.m).
