Overview
Component Identification
Before installing the system you should be familiar with
all the Therm-O-Flow system components. See FIG. 1.
Contact your Graco distributor for help in designing a
system to suit your particular needs.
The air-powered ram extruder forces high viscosity fluids into the intake valve of the fluid pump. Wiper rings
and other accessory equipment for use with this ram are
listed in 253154 and 253160 Controls on page 58.
•
Air Motor Air Regulator (C) controls the pump outlet
pressure by adjusting the air pressure to the air
motor.
•
Ram Up/Down Lever (R) changes the direction of
the ram.
•
Ram Air Regulators (N, P) control the air pressure
to the ram. There are separate air regulators to control the ram pressure in the up and down directions.
EasyKey Display and Keypad
Air Line Components
The following components are included with the unit.
See FIG. 1.
EasyKey is a simple user interface consisting of an LCD
display and keypad (L) which controls Therm-O-Flow 20
operations.
Air and Fluid Hoses
The Air Motor Bleed-type Master Air Valve (D) is
required in your system to relieve motor air pressure.
Trapped air can cause the pump to cycle unexpectedly, which can result in serious bodily injury.
The Therm-O-Flow 20 requires Graco single-circuit
material hoses rated at a maximum of 1250 Watts.
When installing a system make sure that all air and fluid
hoses are properly sized and pressure rated for the system.
•
System Bleed-type Master Air Valve (A) is used to
shut off the air supply to the entire system.
Fluid Line Accessories (Typical)
•
Air Line Filter (B) removes dirt and moisture from
the compressed air supply.
•
Air Motor Enable Solenoid/Depressurization Valve
(V) opens to allow air to the Air Motor Air Regulator
(C) and exhausts air from the air motor at shutoff.
The built-in control delays start-up to allow material
to heat thoroughly.
A pressure compensator valve controls fluid pressure to
the gun/valve, and dampens pressure surges. Install a
pressure compensator valve in the fluid line, using
adapters as necessary.
•
The Air Motor Remote Piloted Air Regulator (X) regulates air pressure to the air motor.
•
Air Motor Bleed-type Master Air Valve (D) shuts off
the air supply to the air motor and bleeds trapped air
from the air motor.
Pneumatic Control Panel
The Pneumatic Control Panel (M) includes the following.
See FIG. 1.
•
Platen Blow-off Valve (S) directs air to the underside
of the platen when depressed.
•
Blow-off Air Regulator (T) controls the air pressure
to the platen blow-off valve.

Installation
Grounding
Ground the supply unit as instructed here and in the
individual component manuals.
The power source conduit is not an adequate ground
for the system. The unit must be bonded to either the
building ground or a true earth ground. To reduce the
risk of static sparking, ground the pump, the object
being dispensed to, and all other spraying/dispensing
equipment used or located in the spraying/dispensing
area. Check your local electrical code for detailed
grounding instructions for your area and type of
equipment.
•
Air and fluid hoses: Use only electrically conductive
hoses.
•
Dispensing/Spray Gun: Follow the dispensing/spray
gun grounding instructions.
•
Object material is applied to: Ground according to
your local code.
•
Material pails: Ground according to your local code.
Use only metal pails placed on a grounded surface.
Do not place the pail on a nonconductive surface,
such as paper or cardboard, which interrupts the
grounding continuity.
•
Maintain grounding continuity when flushing or
relieving pressure: Follow the instructions in your
separate gun manual for safely grounding your gun
while flushing.
Check Resistance
Check the Resistance Between the Supply
Unit and the True Earth Ground
The resistance between the supply unit components
and true earth ground must be less than 0.25 ohms.
Have a qualified electrician check the resistance
between each supply unit component and the true earth
ground. The resistance must be less than 0.25 ohms. If
the resistance is greater than 0.25 ohms a different
ground site may be required. Do not operate the system
until the problem is corrected.
Use a meter that is capable of measuring resistance at this level.
Sensor Resistance Checks
Conduct these electrical checks with the main disconnect OFF.
The package includes a heat sensor and controller for
each of the six heated zones. To check sensor resistance:
1. Make sure the power is off and that the disconnect
switch is in the OFF position.
2. Make electrical resistance checks for the components.
3. Replace any parts whose resistance readings do
not comply with the ranges listed in Table 2.
Check resistance at ambient room temperature
(63°– 77°F [17°– 25°C]).

Installation
Purging the System
Purging the system before the initial use can prevent
material contamination, which may cause the material to
fail or perform poorly.
CAUTION
Purge the system before performing the initial material
loading procedure. The system was factory- tested
using a light soluble oil, a soybean oil, or some other oil
as tagged. Flush the system to avoid contaminating
the material that has been designated for initial material loading.
To purge the system perform the following procedure:
1. Select the material for the initial material load.
2. Verify whether the factory-test oil and the initial
material load are compatible:
3. Select a pail of material that can eliminate the factory-test oil from the system. If necessary, check
with Graco or the material supplier for a recommended solvent.
4. Before purging be sure the entire system and waste
pail are properly grounded. Refer to Grounding on
page 14.
5. Turn all heat zones to 70°F (21.1°C). This allows air
to the air motor, with no alarms, in a cold state. Heat
soak must = 0 or you will need to wait for the preset
time to elapse (default is 45 minutes).
Remove any dispense valve orifices before purging. Reinstall after purging has been completed.
6. Purge the material through the system for approximately 1 to 2 minutes.
7. Remove the pail if purge material was used.
a. If the two substances are compatible omit the
remaining steps in this procedure and refer to
the start up and operation instructions.
b. If the two substances are incompatible perform
the remaining steps in this procedure to flush
the system at ambient temperature.
Use fluids that are chemically compatible with the
equipment wetted parts. See the Technical Data sections of all the equipment manuals.
This equipment should not be used with more than one
type of fluid due to potential compatibility issues which
could result in an unpredictable reaction. Graco recommends using new hoses when chemicals are changed
or care must be taken to assure that all traces of one
chemical are removed before introducing a second
chemical.

Operation
Pail Changing
1. Place the ram UP/DOWN lever in the UP position.
Follow the procedure below to change the pail on a fully
heated machine.
CAUTION
Be sure to reload the empty supply unit with a full
pail of material immediately. Do not raise the ram
and remove the platen from the empty pail until you
are ready to immediately install a new pail.
Do not raise the ram and remove the platen from
the empty pail unless the supply unit is at full
operating temperature. Pail changes can only be
performed when the system is heated.
Do not use a pail of material that has been dented
or otherwise damaged; damage to the platen wiper
can result.
No Pail Low/Empty Sensors
The pump will cavitate and a pump runaway error will
appear in the EasyKey status bar. The air motor will
shut off and the heat will continue to be applied for
approximately 1 hour.
TI8141A
2. Dial ram up regulator pressure to 0 psi.
Excessive air pressure in the material pail could
cause the pail to rupture, causing serious injury. The
platen must be free to move out of the pail. Attempting to change a pail when the supply unit is cold could
result in injury, damage to the equipment, or rupture
of the material pail. Never use pail blow-off air with
cold adhesive or a damaged pail.
Positive pressure is released from the pail when
the platen seal is pulled clear.
3. Adjust the platen blow-off air regulator (T) to 20-30
psi (138-207 kPa, 1.4-2.1 bar).
With Pail Low/Empty Sensors
“Drum Empty” will appear in the EasyKey status bar.
The air motor will shut off and the heat will continue to
be applied for approximately 1 hour. The pump icon will
flash in the status bar. If the light tower kit is installed a
flashing yellow light indicates that the pail is empty and
ready to change. In a tandem system a flashing red light
means that both pails are empty and the system has
shut down.
In a Tandem system, after a pail change has
occurred on the inactive unloader, pressing the

Light Tower Kit (253547)
The optional light tower kit has the following color and
flashing lights to signal warnings and alarms. See FIG.
25.
Green denotes an active system where the pump will
activate when material is needed.
Yellow denotes user attention is required.
Flashing yellow denotes a pail is empty (when
equipped with proximity sensors).
Red denotes immediate user attention is required due to
an alarm condition or interruption of material flow. The
user should be aware that in the case of a motor error
on a Single or Tandem system, or a Tandem system
with both pails empty, heat may be applied to the platen
and pump to allow for a pail change.

Pail Low and Empty Sensor Kit
(255233)
The Pail Low and Empty Sensor Kit is used to indicate
that a pail is EMPTY or LOW, depending on the adjustment of the proximity switch. The kit contains a sensor
mounting bracket (A), activator (B), sensors (C), and a
cable for connecting to the Therm-O-Flow 20 control
panel. See FIG. 28.
The low and empty conditions will be displayed in the
status bar of the EasyKey display. An optional light
tower is also available.
With the optional light tower a yellow light indicates a
pail low condition. A flashing yellow light indicates a pail
empty condition. In a tandem system a red light indicates both pails are empty. See Light Tower Kit
(253547), page 61.
When ordering this kit individually to connect to an existing Therm-O-Flow 20 unloader assembly, use the bolts,
screws and washers provided to mount to the closest
ram post to the control panel. Mount the limit switches to
the bracket as shown.
Increasing the distance between the low and empty sensors (C) increases the heat up time for the tandem secondary system. Lowering the pail empty sensor forces
the heated platen lower into the pail. If this is set too low
the pump could cavitate causing a system alarm.

Ethernet Kit (253566)
This kit is intended for use with the unloaders and
accessory box. The Ethernet kit is designed so that the
user will have network access to the Therm-O-Flow 20
unit and can clear, display, download, restore, and reset
various values from a remote location. This kit includes
a Graco Ethernet Expansion Board (15H816), internal
Cat 5E patch cord, and the RJ45 panel mount jack.
