Installation
Grounding
WARNING
FIRE AND EXPLOSION HAZARD
Before operating the pump, ground the
system as explained below. Also read
the section FIRE AND EXPLOSION
HAZARD on page 4.
1. Pump: use a ground wire and clamp as shown in
your separate pump manual.
2. Air hoses: use only electrically conductive air
hoses.
3. Fluid hoses: use only electrically conductive 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 connec-
tion 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 con-
ductive, 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.

HEATED CIRCULATING SYSTEM
WARNING
To reduce the risk of serious injury, including fluid
injection, splashing in the eyes or on the skin,
burns from hot fluid or heated surfaces, electric
shock or property damage, always follow these
precautions when installing the heater.
1. Shut off the electric circuit.
2. Relieve air and fluid pressure in the system.
3. Have a trained and qualified person install and
wire the heater.
4. Be sure the installation is in compliance with all
local, state, and national codes.
5. Do not install any shutoff devices downstream
from the heater.
WARNING
Heat causes the fluid to expand. If fluid in the
heated portion of your system is trapped with
nowhere to expand, it can cause a system rupture.
A system rupture can result in serious 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 down-
stream from the heater.
3. OR, install a pressure relief valve (P – see the
Installation drawing above), preset to relieve
pressure when it exceeds the system’s maxi-
mum working pressure.
4. Never install any shutoff device between the
heater and gun. If you are using a fluid regula-
tor before the gun, never use it as a shutoff
device.

307363 7
Installation
Mounting the Heater
This Typical Installation is only a guide to setting up
a heated, circulating spray system. For assistance in
designing a system to suit your needs, contact your
Graco distributor.
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. 2. 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 Dimensions on page 22 and
Technical Data on page 20.
Fig. 2
Q
P
19
Install a fluid shutoff valve (G) UPSTREAM from the
heater. This is used to isolate the heater when it re-
quires 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.
Connecting the Hoses
Connect the fluid lines to the 1/2 npt(f) inlet and outlet
of the heater. See the Typical Installation, on page
6.
To minimize heat loss, fluid lines should be insulated
when they are especially long if the environment is
cool.
WARNING
When using a flexible power cord, the attached
equipment is no longer explosion proof rated. To
reduce the risk of serious injury from a fire or
explosion, do not use the heater near flammable
materials or vapors.
Locate the heater where operators will not come in
contact with the hot metal surfaces.
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. 3.
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.

Operation
Pressure Relief Procedure
WARNING
SKIN INJECTION HAZARD
Fluid under high pressure can be in-
jected through the skin and cause
serious injury. To reduce the risk of an
injury from injection, splashing fluid, or moving
parts, follow the Pressure Relief Procedure
whenever you:
Dare instructed to relieve the pressure,
Dstop spraying,
Dcheck or service any of the system equipment,
Dor install or clean the spray tip.
1. Lock the gun trigger safety.
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. Unlock the gun trigger safety. Maintaining firm
metal-to-metal contact between the gun and a
grounded metal pail, trigger the gun to relieve
pressure. Lock the gun trigger safety.
6. Open the fluid filter drain valve, having a container
ready to catch the fluid.

307363 9
Operation
Flushing the Heater Before First Use
The heater was factory tested in 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.
WARNING
To reduce the risk of serious injury when flushing:
1. Use the lowest possible pressure to reduce the
risk of fluid injection and splashing solvent in
the eyes or on the skin.
2. Maintain firm metal-to-metal contact between a
metal part of the gun and a grounded metal pail
to reduce the risk of static sparking which can
cause a fire or explosion.
WARNING
To reduce the risk of serious injury from a fire or
explosion, never operate the heater with its covers
removed.
Priming the System (Refer to page 6)
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 on page 6.
Setting the Heater Controls (See Fig. 4)
NOTE: The knob settings for Series E and older
Vis–Con heaters will differ 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.
1. Stop the pump.
2. Set the control knob (V) at 4 or 5 (trial setting) and
let the heater warm up for about 10 minutes. See
Fig. 5.
NOTE: Start the pump and circulate the fluid at a low
speed – 10 to 20 oz/min. (0.30 to 0.35 liter/min.) –
during the warmup.
Adjusting for Spraying
1. Start the pump and check the fluid flow through
the gun.
2. Readjust the control knob setting, if necessary, to
obtain the proper temperature for spraying.
3. In a Hydra–Sprayrsystem 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.
4. In a circulating system, adjust the back pressure
valve, also.

NOTE: Shaded area indicates continuous op-
eration capability of one heater. Use more heat-
ers if your needs exceed these guidelines.

Operation
Determining the Proper Fluid Temperature
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 peri-
ods of time decreases the heater life.
Higher than necessary temperatures also causes the
fluid to dry out, resulting in a poor finish and clogging
the heater.
The chart in Fig. 6 is used on determining the Under–
Boilrtemperature. It also shows the effect of tempera-
ture on reducing viscosity. Notice that most of the
viscosity reduction occurs by 55_C (130_F).
Under–Boil is the Graco method of hot, airless spray-
ing in which the fluid is heated to a temperature just
under the boiling point of its most volatile solvent.
To find the Under–Boil temperature of your fluid:
1. Pour a small sample into a heat–proof container.
2. Measure and record the temperature and viscosity
of the fluid. Use a No. 2 Zahn cup.
3. Heat water in a large container to 93_C (200_F).
Place the sample in the water.
4. At every 10_temperature rise, measure and
record the viscosity and temperature. Do this until
solvents start boiling off and the viscosity starts to
level off – usually 71_to 77_C (160_to 170_F).
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 viscos-
ity records. This is the temperature to use in your
Under-Boil system.

TEMPERATURE (_F)
The chart in Fig. 7 shows the effect of tempera-
ture in reducing two fluids to a sprayable vis-
cosity – 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 10_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.
Also note that once the fluid is reduced to
about 34 on the chart, viscosity reduction starts
to level off. Therefore, high temperatures will
not significantly improve sprayability, but will
use more energy.

Maintenance
Flushing After Use
1. Drain and clean the fluid filter frequently to be sure
it 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.
2. Flush the heater often enough to prevent a buildup
of dried sediment in it.
WARNING
Before flushing, always shut off 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 injury from burns.
CAUTION
Clogged fluid passages can be very difficult 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.
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. Re-
move the drain plug (7) in either end plate and
drain the fluid into a container. See. Fig. 8.
5. Shut down.
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.

Unclogging Fluid Passages
1. 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.
2. Put the end plate back on, turning all screws hand
tight.
3. Follow the sequence shown in Fig. 9, torquing
each screw to 50 in-lb (5.6 NSm).
4. Torque them again, using the same sequence, to
175–225 in-lb (20–25 NSm).
