components.
Warning and Safety Precautions
The CD-200 can develop fluid pressures in excess of 1000 pounds per square
inch. Everyone within 25 feet should wear eye protection when the system is
energized. Mechanical members are actuated under forces of up to 500 psi.
Maiming injuries can be incurred. Do not energize the system unless all
screens are in place, and fingers, tools, and other objects are outside of the
frame of the machine.
Become thoroughly acquainted with first-aid procedures recommended by your
resin supplier. If solvents are to be used for cleaning, personnel should
become thoroughly acquainted with their characteristics. Most solvents are
hazardous under all circumstances and extremely dangerous in non-ventilated
areas, or at elevated temperatures.
A thorough understanding of the Operator’s Manual is crucial to the safe
operation of the CD-200. Do not attempt to operate this system until thoroughly
familiar with it’s contents. Phone Lily Corporation if clarifications are needed.

Air Supply
Requirements & Connections
The volume of dispensed resin is determined by air pressure. An inadequate supply of air will result
in sluggish performance. 18 SCFM of air at 100 psi should be the minimum required for proper
operation of the CD-200 Dispenser. The maximum air pressure to the CD-200 Dispenser should not
exceed 125 PSI. For the air requirements of the transfer pumps, please refer to the manufacturers
operators manual.
As shown in the picture below, the air line from the compressor is connected to the lower fitting on
the back of the CD-200 Dispenser. There are fittings on the back of the CD-200 Dispenser for
connecting the air supply hoses that go to their respective transfer pumps also. These are labeled
“A” and “B”. The air pressure to the transfer pumps is controlled by the regulators on the front of the
machine.
The air supply must be clean and dry. Built into the
CD-200 Dispenser is a moisture separator and a
coalescing micro filter. Both of these units are auto
draining and will drain when the air pressure is
removed from the system. Both filters have a nylon
tube attached to allow the drained fluid to be directed
into a container if desired. The micro air filter also has
an indicator located on the top of the housing to
indicate when it needs to be serviced.
Always blow out air hoses before connecting them to
the machine to remove any accumulated moisture and
debris, preventing it from entering the dispenser. The
air connections used on the CD-200 are the Chicago,
or claw style fittings.

The Resin Supply
Fluid Connections
Connect the material supply hoses from the transfer pump outlet fittings to the material inlet fittings at
the rear of the CD-200 Dispenser. The material inlet fittings are labeled “A” and “B” while the transfer
pumps are identified as “A” and “B” also. The fluid fittings are 3/4” JIC.
If you are using 55 gallon drums then attach the suction hose to the inlet of the transfer pumps and
insert the steel pipe into the 2” opening on the top of the drum. There will also be a tee at the outlet
of the transfer pump with a section of hose and a valve. This valve should be mounted to the 3/4”
opening on the top of the drum. This is the re-circulation valve and is used after moving the “Stick”
from one drum to the next. It’s used to get rid of any air that may have been picked up during the
move. During normal operation this re-circulation should be closed. To re-circulate open the valve
and run the transfer pump for a couple of minutes. This should remove any air that might have been
picked up when the suction pipe was moved from one drum to another. Not removing air from these
lines could result in “off-ratio” material.
If you are using totes the suction hose is attached to the inlet at the bottom of the transfer pumps.
The 2” cam lock is then attached to the outlet of the tote. Be sure to open the valve at the outlet of
the tote as well as opening the lid on the top of the tote.
The dispense hoses are attached to the fittings at the front of the CD-200 Dispenser. They are
labeled “A” and “B”. For the initial setup it doesn’t matter which fittings are used. Once the dispenser
has been used though care must be taken to insure that the hoses don’t get mixed up!

Operation
●Purge the air hose from the compressor of water or other contaminants.
●Be sure that the cabinet On/Off switch is in the “Off” position.
●Reduce the dispenser air pressure to zero by turning the regulator counter-clockwise until it stops
turning.
●Attach the dispense hoses or valve assembly to the outlet fittings.
●Make sure all cabinet covers are in place.
●Energize the transfer system.
Connect the air supply, energize the transfer pumps and switch the dispenser “On”. Slowly increase
the air pressure at the dispenser regulator until the system begins to dispense material. Continue
increasing the pressure to approximately 100 psi while looking for fluid or air leaks. Following this test
reduce the air pressure to that required for the application at hand. The dispense pressure may be
altered at any time by adjusting the regulator. Once the pressure setting has been made the unit will
continue to dispense at that pressure until the setting is changed. NOTE: The dispense pressure
gauge will only register a reading during a dispense cycle
The regulator at the control panel regulates the air pressure only to the main air cylinder when on its
dispense stroke. The pressure it exerts on the metering pistons determines the pressure at which the
resin exits the dispenser. However, the air cylinder pressure is never the same as that of the resin
pressure.
To Begin With
Dispensing

6 Ver. 1.0
Because the resin components are not joined together within the dispenser, no flushing of the inside
of the unit is required. And, most epoxy resins may be left in the unit for a period of time with no
problems. Daily cleaning of the system includes the disposal of the static mixer and cleaning the
threads on the dispense nozzle and mixer retaining nut with solvent. After cleaning, an application of
grease should be applied to the threads to prevent the epoxy from bonding the components, making
future cleaning and removal of the nut much easier. Both metering pistons, inside the unit, should
also be wiped down with solvent and grease applied to them as well.
Although the resin components within the unit are not mixed they will crystallize over time. Therefore
for extended shutdowns it is recommended that the entire system be flushed with Acetone or Methyl
Ethyl Ketone to remove accumulations of resin from the unit. The solvent should then be followed
with hydraulic fluid. The hydraulic fluid will not evaporate or crystallize, keeping the system well
lubricated until required again.

WARNING! The CD-200 contains moving parts which are by definition wearing parts. Critical
components are wearing from the moment the system is energized. It is absolutely essential that this
wear be anticipated and monitored to assure proper ratio dispensing. Key personnel must become
familiar with the following procedure for monitoring the wear of metering seals, for if it does not
become routine, improperly metered material will result.
A check once each week of operation is usually sufficient to detect seal wear before it becomes a
problem. The frequency required will vary with the volume of material being dispensed. If the
application is especially critical, then the monitoring should be more frequent.
1. Start the ratio test with the air supply disconnected from the dispenser, the fluid lines from the
transfer pumps to the CD-200 connected, and the air lines from the transfer pumps to the CD-200
connected.
2. Make sure that the “ON/OFF” switch on the CD-200 is in the “OFF” position.
3. Make sure all the pressure regulators on the CD-200 are turned to Zero. You can do this by
turning the knob all the way to the left till the knob stops turning.
4. Disconnect the dispense hoses and allow the resin within the outlet fittings to drain.
5. Connect your air supply to the CD-200 dispenser and energize the air supply.
6. Slowly increase the air pressure to the transfer pumps to 80 psi.
7. Observe the outlet fittings for at least one minute for any signs of leakage. Depending on the
viscosity of the resin being dispensed it may take up to 15 minutes to see the flow of the resin to
slow or stop. If the flow of resin does not stop then the ball valves will need to be rebuilt by
replacing the ball valve seals. If there is no leakage then proceed to the next step.
8. Reduce the pressure to the transfer pumps to “ZERO”.
9. Switch the Isolation Valve to the “Closed” (down) position. (The isolation valve is located inside
the cabinet mounted on the base manifold).
10.While holding a waste bucket over the outlet fittings, move the “ON/OFF” switch to the “ON”
position. WARNING! Hold this bucket firmly! When switching the “ON/OFF” there could be a
blast of air from the outlet fittings.
10.Slowly increase the “Dispenser” air pressure until the machine starts to dispense resin into the
waste bucket.
11.Once this dispense cycle is complete, wipe the dispense fittings clean and allow accumulated
resin within the fittings to drain. Observe the fittings for at least one minute. It could take up to 15
minutes depending on the viscosity of the resin for the flow of resin to stop. If the flow does not
stop or at least slow down, the ball valves will need to be rebuilt by replacing the ball valve seals.
If there is no leakage then this means that the ball valve seals are good and the machine is “On
Ratio”.

14.While holding a waste bucket under the outlet fittings again, Switch the isolation valve to the “Open”
position (Up).
15.Move the dispenser “ON/OFF” switch to the “OFF” position. The machine will return to the “Park” position.
16.Turn all of the pressure regulators back to “Zero”
17.Re-connect the dispense hoses and replace any covers that were removed for testing.
Caution: The above procedure is the only procedure that assures ratio accuracy for the CD-200. Random
volumetric comparisons taken at low pressures or high flow rates do not reveal the condition of the ball
valve seals. Only an extended and significant fluid pressure can accurately reflect their condition.

Ratio Assurance Test

9 Ver. 1.0
Operation
Ratio is determined by the relative diameters of the catalyst and base pistons. If the ratio is 1:1, both
metering pistons will be the same. However, with any other ratio, the catalyst metering piston will be
of a smaller diameter. Ratio is therefore changed by exchanging one catalyst metering assembly for
another. A metering assembly consists of a metering cylinder, a metering piston, and the seals, etc.
component to them. Metering assemblies for alternate ratios are available from Lily. A few simple
steps are required to change ratio:
1. De-energize the transfer pumps by turning their
respective regulators to “0 PSI”. With air connected to
the CD-200 Dispenser, turn the dispenser “Off”. This
will open the inlet ball valves and close the outlet valves
and send the main air cylinder to the “Park” position.
3. Disconnect the catalyst (B) supply hose from the
transfer pump. Grip the catalyst metering piston and
press it in until it is all the way into the metering cylinder
The material in the metering cylinder will be forced to
flow back through the inlet fitting. If the piston does not
go down easily, use a strap wrench to free it and twist it
as it is pressed in.
4. Use a strap wrench to turn the catalyst metering
assembly counter-clockwise until it is free. Do not
attempt to remove the assembly with any other tool
than a strap wrench, as the chamber may be damaged
by any uneven grasping force.
5. Use the seal pick to remove the base manifold o-
ring. Clean the pocket thoroughly and install a new o-
ring in the proper groove.
6. Important! Lubricate the threads of the replacement
metering assembly with an anti-seize compound or
silicone lubricant. Thread the assembly into the
manifold by turning it clockwise until it is seated. Do not
over-tighten. As the chamber bottoms out in the
manifold you will feel a definite stop. Do not tighten
further.

2. Remove the right and left side panels.

SERVICING THE SYSTEM
If the CD-200 is properly maintained, service will involve little more than routine replacement of
dynamic seals
exposed to material being dispensed. The frequency of seal replacement will depend upon the
material dispensed. Thousands of gallons of non-abrasive resin with good lubricity may be dispensed
with little, if any,
service; while the use of an abrasive – and usually inexpensive – material is likely to necessitate
frequent seal
If the air supply is properly maintained, the system will deliver literally thousands of trouble-free
cycles. However, in the real world, that is not always possible. Therefore, periodic lubrication of the
air circuitry is recommended. To do so, deenergize the system and remove the right cover. Free the
four way air fitting (P-189) fixed to the bulkhead fitting (S-009) by pressing the collar of the elbow
down. Also disconnect the 1/4” tubing next to the four way air fitting. Squeeze a generous dose of
Lily Lube (P-315) into the rigid leg of the four-way fitting and the 1/4” tube. Reconnect the fitting and
tube. No other lubrication is needed. Never use WD-40 or similar products in the air circuit.
Disassembly
Make sure the dispenser switch is off and de-energize the transfer pumps. Disconnect the air supply
to the CD-200 and then remove the resin supply hoses from the rear of the dispenser. Remove both
side panels. Grasp the metering pistons and press them into their cylinders. This will purge the
cylinders of material, which will flow out of the fittings at the rear of the machine.Use a waste
container to catch this material. Then, follow the steps below:
1. Remove the fluid lines from the 3-way ball valve
2. Remove the 4 mounting bolts securing the ball valve to the
mounting bracket.
