Overview
Component Identification
Before installing the system you should be familiar with
all the system components. See FIG. 1 for
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) shuts off the air supply to the air motor and bleeds 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 the 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.

not need to be changed. Refer to the Zone Setup
Screens on page 24 for a list of device types and how to
set them for each zone.
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:
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 are 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.

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.
Positive pressure is released from the drum when
the platen seal is pulled clear.

Light Tower Kit (253547)
The optional light tower kit has the following color and
flashing lights to signal warnings and alarms. See FIG.
26.
Green denotes an active system where the pump will
activate when material is needed.
Yellow denotes user attention is required.
Flashing yellow denotes a drum 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 drums empty, heat may be applied to the
platen and pump to allow for a drum change.

Drum Low and Empty Sensor Kit 253559
Drum Low and Empty
Sensor 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 Drum Low and Empty Sensor 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. 29.
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. See “Light Tower Kit
(253547)” on page 80.
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.
