Thank you for purchasing this TAClWlNA product. Please read this manual
carefully in order to ensure that you use this pump safely and correctly.
Be sure to keep this manual in a place where it will be easily available for
If the CSll series pump you bought conforms to special specifications not
described in this OPERATlOlV Manual, handle the pump according to

For the Safe Use of This Product-\
This manual is intended to help the operator to handle the product safely and correctly. In support of this aim, important
safety-related instructions are classified as explained below.
Be sure to follow them at all times.
/!\(warning)
* If the product is operated incorrectly in contraventionof this instruction, it is possible that an accident resulting in death
or serious injurywill occur.
I
0 This indicates that improper operation can result in an injury or physical damage to the product.
(G+sz-]
Thisindicates information that should always be followed to maximize the product's performanceand service life.
(Note)
a This indicates supplementary explanations.
Conditions of Use
* This pump cannot be used in explosion-proof areas, and in explosivelignitable atmospheres.
This pump can be used for injection of chemicals only. Do not use this pump for other applications. Doing so might cause
accidents or malfunction.
This pump cannot be used for transferring fluids that contain slurry.
Q Do not exceed the following operating ranges. Doing so might cause the pump to malfunction.

* Installthe chemical tank at a place higher thanthe pump.
Also, note that the viscosity that can be transferred or discharge volume change according to the pipingconditionsand the
nature of the chemical.
( Transportation, Installation and Piping )
,+,(-I
Install this pump in a location where it will not come into contact with children or other people besides the operator.
,+,(cX)
If you drop or damage this pump, contact your supplying agent. Continued use in this state might cause accidents or mal-
function.
Do not install this pump at humid or dusty locations. Doing so might cause electric shock or malfunction.
* If the discharge piping is provided with a cut-off valve, and when there is the danger that the piping will choke, install a
relief valve on the piping immediately after the discharge side of this pump.
When using water-diluted solutions in cold areas, chemicals may freeze in the pump head or piping, damaging the pump
and peripheral parts. Be sure to install heating apparatus or heat insulation.
Waterused inthe pre-shipment test may remain on pump liquid-end parts.When using chemicals that generate gas or
harden due to reaction with water, be sure to drain any water and allow liquid-end parts to dry before use.
The discharge volume cannot be adjusted by operating the valves on the discharge piping.
* This pump generates pulsation. Install an air chamber or other pulsation attenuator.
The durability of the hose varies greatly according to the chemicals used, temperature, pressure and degree of exposure
to ultraviolet light. Inspect the hose, and replace with a new one if it has deteriorated.

ff Checking the Product 1
When unpacking,please confirm the following items:
(1 ) Isthe enclosed product the same model you ordered?
(2) Dothe details on the pump nameplate match your order?
(3) Are all the accessories present and correct?
Please refer to the accessory list below.
(4)Can you detect any damage due to vibration
or shock during transportation?
(5) Are there any loose or disconnected screws?
All TACMINA products are carefully checked prior to shipment. If, however,you find a defect, please contact your supplying
agent.

1 Product Description I i
The CSll Series Diaphragm-typeMotor-DrivenMetering Pump can accuratelytransfer f~xedvolumes of liquids at fixed
intervals.
The CSll's pump head has two check valves that allow liquidto pass in only one direction. which helps ensure a fixed
discharge volume per single pump operation.
The CSllSeries is simply designed and iseasy
to maintain.Itcan bedisassembledand inspectedby the user, which
reducesmaintenancecosts.

1 Operation
When handling chemicals, be sure to use protec-
tive coverings (rubber gloves, face mask, protec-
tive goggles, chemical-resistant work clothes,
etc.) matched to the chemicals you are using.
If you forget to open the discharge-side valve or
if foreign matter clogs the discharge piping, the
pressure in the piping and pump head may
increase beyond the range indicated in the pump
specifications. This may result in the chemicals
leaking or spurting, or in damage to the pump or

To adjust the injection amount, turn the adjusting dial.
The scale on this dial is divided into two scales, a pri-
mary dial scale and secondary dial scale.
The primary dial scale indicates the stroke length in
millimeters (mm).
The secondary dial scale is divided into ten equal sec-
tions, with one turn of the dial corresponding to 1 mm.

@ Set the desired stroke length by the primary
dial scale, and make stroke length adjust-
ments of lessthan

*Turningthe adjusting dial CCW increases the dis-
charge volume, while turning it CW decreases the
discharge volume.
* Turning the adjusting dial beyond the effective adjust-
ment range does not increase the discharge volume.

(Important)
For details on the relationship between scale and
~njectionamount, see the performance curves on
pages 31 and 32.
The values Indicated in these performance curves
were obta~nedusing clean water under flxed con-

example, tightening will be uneven if the bolts are
tightened in the order

Avoid installingthe pump inthe direct sunlight. Also,
prevent it from beingexposedto wind and rain.
Thoughthis pump is designed for outdoor use, metal
parts sometimes heat up due to direct sunlight, plas-
tic parts sometimes deterioratedue to UV rays, and
scratches or rust sometimes appears due to grit and
dirt, or rainfall.To prolongthe service life of the pump
when it is used outdoors, we recommendattachinga
shade or cover.
Installthe pump in a locationthat is well-ventilated
during summer, and where chemicalswill not freeze
in winter.
Leave enough space to allow easy access for mainte-
nance and inspectionwork.
Installthe pump on
a flat horizontalsurfaceand fix it
securely to prevent it from vibrating during the opera-
tion.
If the pump is installed on an inclined surface,
the pump may not be able to discharge properly or at
all.
Use the four pump set bolts (provided) for fixing the
pump in positionat the positions shown in the figure
below.

it at the position inthe figure shownbelow.
About the cooling air inlet port
Do not block the cooling air inlet port on the bottom

The mounting of the upper and lower casings of this pump can bechanged 90" so that the
pump head faces three different directions.
Change the mounting orientation when, for example, installation of the pump is
subject to piping restrictions.

cover.
When removing the terminal box cover and partition plate,
and disassembling the upper and lower casings, provide
additional slack for the power leads so that the cases are
not pulledtogether by the power leads.

* Make sure that the 0 ring is fitted into the ter-
minal box cover.
An indent and a protrusion for positioning are locat-
ed on the upper casing (inside)and lower casing
(outside), respectively. After you have changed the
pump head's orientation by turning the upper cas-
ing, make sure that you hear the protrusion click in
place into the indent.
