Overview
Component Identification
Before you install the system you should be familiar with
the system components. See FIG. 1 for the
Therm-O-Flow system components.
Air Line Components
The following components are included with the unit.
See FIG. 1.
•
System Master Air Valve (A) is used to shut off the
air supply to the system.
•
Air Line Filter (B) removes dirt and moisture from
the compressed air supply.
•
Air Motor Air regulator (C) and (V) control the outlet
pressure by adjusting the air pressure to the air
motor.
•
Air Motor Master Air Valve (D) is used to shut off the
air supply to the air motor and bleed trapped air
from the air motor.
•
Air motor Air Supply Hose connects the air regulator
to the air motor.
Air and Fluid Hoses
The Therm-O-Flow 200 requires Graco single-circuit material hoses rated at a maximum of 1250
watts.
When installing a system make sure:
•
all air and fluid hoses are properly sized for your
system.
Heat Control Zone Selection
The Therm-O-Flow 200 has 6 or 8 heat zones. Zones 1
and 2 are always used for the heated drum platen and
the heated pump. Zones 3 and 4, 5 and 6, and 7 and 8
are each available as paired zones through 16-pin connectors. The heated hoses have a 16-pin connector on
the inlet end cable, and an 8-pin connector on the outlet
end cable. All heated valves, manifolds, and heaters are
equipped with an 8-pin matching connector.
Pneumatic Control Panel
The pneumatic control panel includes the following. See
FIG. 1.
•
Auto Depressurization Valve exhausts air from the
air motor at shutoff. The built-in control delays
start-up to allow material to thoroughly heat.
•
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.
•
Ram Up/Down Lever (R) changes the direction of
the ram.
•
Blow-off air regulator (T) controls the air pressure to
the platen blow-off valve.
•
Platen Blow-off Valve (S) directs air to the underside
of the platen when depressed.
User Display (EasyKey™)
•
A simple user interface consisting of an LCD display
and keypad.
•
Keypad contains the buttons which control the
Therm-O-Flow 200 operations.
Vent Hood Kit (if supplied)
The vent hood assembly is designed to efficiently draw
fumes to the factory exhaust system during drum
change-out. This assembly requires a connection to a
factory ventilation system that draws a minimum air flow
of 8.4 m3/min (300 scfm). This kit is recommended for
Polyurethane Reactive (PUR) applications.

code. Use only metal drums placed on a grounded
surface. Do not place the drum 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.
To reduce the risk of fire, explosion, or electric shock:
•
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.

Installation Procedure
Check the Resistance Between the Supply
Unit and the True Earth Ground.
To reduce the risk of fire, explosion, or electric shock
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.
To reduce risk of injury or damage to equipment, conduct these electrical checks with the main disconnect
OFF.
The package includes up to eight heat sensors and controllers for each of the 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.

Installation Procedure
Overview of the Temperature
Controller Settings
a. If the two substances are compatible omit the
remaining steps in this procedure and refer to
the start up and operation instructions.
Temperature controls are set in the zone configuration
setup screens. See Run Screens on page 24 for information about setting temperature controls.
b.
If the two substances are incompatible perform
the remaining steps in this procedure to flush
the system at ambient temperature.
P, I, and d settings are preset for device types and will
not need to be changed. Refer to the Zone Setup
Screens on page 25 for a list of device types and how to
set them for each zone.
Purging the System
Purging the system before its 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:
Use fluids that are chemically compatible with the
equipment wetted parts. See the Technical Data sections of all the equipment manuals.
3. Select a drum 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
drum is properly grounded. Refer to Grounding on
page 16.
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.
Remove any dispense valve orifices before purging. Reinstall after purging has been completed.
1. Select the material for the initial material load.
2. Verify whether the factory-test oil and the initial
material load are compatible:
6. Purge the material through the system for approximately 1 to 2 minutes.
7. Remove the drum if purge material was used.

Installation Procedure
Optional Low Level Kit 253559
This kit is standard on Code G options A,T, and S. The
kit must be purchased if Code G option B is selected.
The Low Level Kit is used to indicate that a drum 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 200 control panel. See
FIG. 6.
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
drum low condition. A flashing yellow light indicates a
drum empty condition. In a tandem system a red light
indicates both drums are empty.
When ordering this kit individually to connect to an existing Therm-O-Flow 200 unloader assembly, use the
bolts, screws and washers provided to mount to the
closest ram post to the control box. 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 drum empty sensor forces
the heated follower plate lower into the drum. If this is
set too low the pump could cavitate causing a system
alarm.

Drum Changing
Follow the procedure below to change the drum on a
fully heated machine.
CAUTION
Be sure to reload the empty supply unit with a full
drum of material immediately. Do not raise the ram
and remove the platen from the empty drum until you
are ready to immediately install a new drum.
In a Tandem system, after a drum change has
occurred on the inactive unloader, pressing the
Pump Ready button will allow five minutes of air to
the air motor to allow for the pump to be primed.
The inactive unloader must be within its warning
deviation setpoints and in the Ready or Heat On
state. If the five minute timer runs out before the
inactive unloader is primed, pressing the Pump
Ready button again will repeat the air to the air
motor.
1. Place the ram UP/DOWN lever in the UP position.
Do not raise the ram and remove the platen from
the empty drum unless the supply unit is at full
operating temperature. Drum changes can only be
performed when the system is heated.
An empty drum clamp can interfere with the up
and down operation of the ram. When raising or
lowering the ram, make sure the drum clamp stays
clear of the platen assembly.
Do not use a drum of material that has been
dented or otherwise damaged; damage to the
platen wipers can result.
TI8135A
2. Dial ram up regulator pressure to 0 psi.
No Proximity Sensors
The pump will cavitate and a motor 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.
With Proximity 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. If the light tower kit is
installed a flashing yellow light indicates that the drum is
empty and ready to change. In a tandem system a flashing red light means that both drums are empty and the
system has shut down.
Excessive air pressure in the material drum could
cause the drum to rupture, causing serious injury.
The platen must be free to move out of the drum.
Attempting to change a drum when the supply unit is
cold could result in injury, damage to the equipment,
or rupture of the material drum. Never use drum
blow-off air with cold adhesive or a damaged drum.

interrupt switch by pushing the TEST button.
Power in a Tandem System
In a Tandem System, the secondary unloader provides 24VDC power to the EasyKey display. This
allows the primary unloader to be powered down
for maintenance without interrupting production. All
accessories (light tower, swirl, etc.) and the display
board on the primary system will have power when
the secondary unloader is powered on and the primary unloader is powered off.
