Note
Pure water exposed to the
atmosphere will absorb CO2. This
will lower resistivity and pH.
1
Using average tap water. Delivers deionized water in continuous flow at atmospheric pressure. Although the
cartridge holder can be operated at inlet pressures up to 700 kPa (100 psig), the cartridge holder cannot
without any back pressure. Ensure that maximum flow rate is not exceeded, the outlet is open to atmosphere,
and there are no tubing restrictions.

Provided with 1.7 m (5-1/2”) electrical cord and plug.

High Capacity
This cartridge (catalog no. D0803) has the
capacity to remove 113 grams (1740 grains) of
dissolved ionized impurities (as NaCl) to an
endpoint of 50,000 ohm-cm. This high capacity
configuration produces water with an electrical
resistivity of about 175,000 ohm-cm. Each
cartridge will purify about 660 liters (175
gallons) of water containing 170 mg/liter (10
grains/gallon, as NaCl). The pressure drop
across the cartridge is less than 7 kPa (about 1
psig) at 38 L/hr (10 GPH) when the cartridge is
new.
Ultrapure (Mixed Resin)
This cartridge (catalog no. D0809) has the
capacity to remove 65 grams (750 grains) of
dissolved ionized impurities (as NaCl). About
3/4 (75%) of the capacity is capable of
producing water with an electrical resistivity
greater than 1 megohm/cm. Each cartridge will
purify about 380 liters (about 100 gallons) of
water containing 170 mg/liter (10 grains/gallon,
as NaCl) to 20,000 ohms. The pH is 6.8 to 7.2,
and the water produced is largely free of silica.
The water is also free of CO2until exposed to
atmosphere. The pressure drop across the
cartridge is less than 7 kPa (about 1 psig) at 38
L/hr. (10 GPH) when the cartridge is new.

Unpacking
Unpack the Bantam Holder carefully so that none
of the parts will be marred or damaged. Ensure
that any loose parts — such as tubing and fittings
for the plumbing service connections — are not
discarded with the packing materials.
Choosing a Site
Move the Bantam Holder to the desired operating
location. The holder should be installed in a
location accessible to a water supply (raw water
faucet). Also, the unit should be accessible to an
electrical outlet. The holder is equipped with a
1.7m (5-1/2') electrical cord.
Mounting
The Bantam Holder is shipped assembled for
bench mounting. Four screws are provided for
wall mounting if desired.
Plumbing Service Connections
The Bantam Holders are supplied with
polypropylene elbows, inlet and drain tubing, and
straight connectors. The plumbing service
connections are accomplished as follows:
1. Remove the fitting and screen from the
raw water faucet opening.
2. Install a customer-supplied 3/8" NPT x
1/8" NPT brass bushing in the faucet
opening. The 1/8" NPT portion of the
brass bushing is used to connect the
Installation
Note
It is suggested that the Bantam
Holder inlet be connected to a raw
water faucet. Other means of
connecting the holder inlet to a raw
water supply can be used, if
desired.

7
1/8" NPT x 1/4" OD straight connector
provided to connect the Bantam Holder
inlet to the raw water supply. If the raw
water supply service connection is not
3/8" NPT, use another brass fitting as
required.
3. Cut a piece of tubing from the 2.1m (7')
of 1/4" OD tubing (part no. TU1494X1)
provided to make the plumbing service
connection between the raw water faucet
and the plumbing service connection
marked “inlet” on the Bantam Holder.
Ensure that sufficient tubing is left to
drain the holder through the plumbing
service connection marked “drain” on the
Bantam Holder to the sink and to make
the plumbing service connection
between the holder effluent connection
at the top of the unit and the point of
distribution.
4. Thread the 1/8" NPT x 1/4" OD straight
connector provided (part no. 15451) into
the brass bushing at the faucet opening
and connect the tubing between this
connection and the plumbing service
connection marked “inlet” on the holder.
5. Ensure that the 1/8" NPT x 1/4" OD
polypropylene elbow (part no. 15847) is
threaded into the effluent connection at
the top of the holder and connect tubing
between this connection and the point of
distribution. See Elbow-Tubing Assembly
in this manual to ensure that the
connection is made properly to prevent
leakage.
INSTALLATION

Elbow Tubing Installation
6. Connect the remaining tubing to the
plumbing service connection marked
“drain” and extend the tubing into the
sink to allow the holder to be drained in
an unrestricted manner.
Elbow-Tubing Assembly
Assembling the tubing and polypropylene elbow
is accomplished as follows to ensure against
leakage.
1. Remove the adapter nut, being careful
not to lose the o-ring, backup ring, and
stainless steel grab ring.
2. Remove the o-ring from the elbow.
3. Install the metal grab ring and backup
ring in the adapter nut, and install the
nut on the elbow. Do not install the
o-ring at this time.
4. Push the tubing through the nut until it
bottoms out in the elbow.
5. Remove the adapter nut, then install the
o-ring on the tubing. Do not push the
backup or metal grab rings back on the
tubing when installing the o-ring on the
tubing.
6. Install the adapter nut on the elbow and
hand-tighten the nut.
INSTALLATION
Caution
Do not restrict the tubing and run
the tubing in an upward direction
from the top of the unit. Any
restriction on the outlet can result in
a cartridge bursting and flooding.
Caution
Do not apply a wrench to the nut—
the nut should be hand-tightened
only to prevent leakage.

9
Cartridge Installation
Install a cartridge in the holder as follows:
1. Install the large o-ring (part no. 06419)
on the cartridge holder. A small o-ring
should be on the bottom of the cell.
The large o-ring is packaged
separately during shipment.
2. Install the fresh cartridge in an upright
position, the large opening toward the
bottom. The lower tightening wheel
should be turned down to allow the
cartridge to be centered between the
top and bottom o-ring.
3. Turn the lower tightening wheel until
the cartridge seats against the top
o-ring.
INSTALLATION
Note
Water purified by the
ion-exchange method is not
necessarily free from odor and
color. In some instances, color or
odor could be introduced by trace
quantities of free amines or low
molecular weight polymers which
are present in fresh untreated
resin. Generally, the amine odor
lessens or disappears after
passing a few gallons of water
through the holder.
Caution
Do not over-tighten the tightening
wheel.

10
Operate the Bantam Holder as follows:
1. Close the drain valve.
2. Open the inlet valve one to two turns
and allow a couple of minutes for the
cartridge to fill. If leakage occurs at an o-
ring, close the inlet valve, loosen the
lower tightening wheel enough to rotate
the cartridge 90°, and retighten. Open
the inlet valve and recheck for leakage.
3. When water issues from the tubing,
adjust the inlet valve to the desired flow
rate (see Cartridge Technical Character-
istics ).
Purity Meter Operation
Operate the Direct Reading Meter by setting the
on/off switch to the “on” position. When the purity
meter drops below the acceptable minimum
purity, or when the purity meter needle registers
in the 0.05 to 0.025 megohm red range, the
cartridge should be replaced. The meter provides
a constant indication of the water purity. The
meter scale is calibrated 0 to 19 PPM (ionizable
impurities) with equivalent indications in
megohms resistance from 0.025 to 18, making
possible constant monitoring of the water purity.
To stop the meter from operating, set the on/off
switch to the “off” position.
Operation
Caution
Do not exceed a flow rate of 38
LPH (10 GPH). Leakage will occur if
this flow is exceeded.
Caution
Do not over-tighten the tightening
wheel.

11
Maintenance of the Bantam Holder should be
minimal, involving cartridge replacement and
o-ring seal replacement. Also, an occasional
calibration check of the purity meter might be
necessary. Cartridges should be stored away
from heat.
Calibration
Calibrate the Direct Reading Meter as follows:
1. Set the on/off switch to the “off” posi-
tion.
2. Check the zero alignment of the meter
needle to the meter scale. If required,
rotate the zero adjustment screw until
the meter needle is aligned with the
line indicating the beginning of the
meter scale. The zero adjustment
screw is located on the face of the
meter below the scales.
3. To calibrate the meter further, connect
a known resistance across the cell
terminals. A 50,000 ohm resistance
should correspond to “0.05” on the
meter scale.
4. With the on/off switch set to “on,”
adjust the potentiometer (screwdriver
adjustment) at the bottom of the meter
case to make the scale reading
correspond to the simulated resis-
tance.
Maintenance and Servicing
Warning
To avoid electrical shock, always
disconnect the power supply
before maintenance and
servicing. Refer servicing to
qualified personnel.
