Introduction
Congratulations on your purchase of our revolutionary Bottle-less Water
Cooler! Our coolers are all designed to replace the conventional 5 gallon
water bottle while eliminating the hassles of deliveries, lifting bottles
and eliminating plastic bottles from landfills. Our coolers are designed
to produce pure great tasting water for the whole family that is clean
and safe to drink.
Our coolers are connected to your city or well water supply to efficiently
filter out tastes and odor, and to remove microscopic contaminants by
using reverse osmosis purification technology. We manufacture a wide
range of models to fit any home or office application.
The H2O-2000 Model has 3 temperature faucets; cold water is chilled
around 44ºF, hot water is heated at 180ºF and ambient.
All International H2O models are manufactured and marked as “RO” or
“F” assemblies. The “RO” assembly utilizes CSM Reverse Osmosis water
purification technology which produces pure safe water from city or
well water. The “RO” assembly is comprised of a 5-micron sediment
filter, a carbon (GAC) 10-micron filter, CSM RO membrane and a post
carbon filter to improve taste. The “RO” filter assembly requires a drain
line connection to be installed which removes rejected water to the
sewer.
The “F” assembly is comprised of sediment and carbon filter system, but
not the RO membrane; therefore, it does not require a drain line
connection.

4 | P a g e
CAUTION: The filter version “F” must be used only with softened
water or water that has less than 3.5-grains of hardness to prevent
scaling and premature burnout of the heating elements.
Receiving the Cooler
Unpacking
International H2O products are shipped completely assembled and
ready to operate. Remove the top of the box and slide the water cooler
out and save the box and packing materials.
Inspection
Inspect the cooler for shipping damage. Look at the exterior panels to
see if they have been dented or damaged. Check the dispensing spigots
in the front. Open the bottom panel to assure that the filter system is
intact. Look at the back of the cooler to see if the compressor is secure
and has not broken from the mounting. Inspect filter system to see that
nothing is damaged or dislodged from shipping.
Description Model H2O-2000
The H2O-2000 Model provides water at 3 different temperatures,
dispensed from three spigots, “hot”, “cold” and ambient. The assembly
drawing is shown in Figure 1. Water flows from the filter system into the
ambient tank and the cold water tank simultaneously. The cold tank
then feeds the hot tank which is heated by internal heaters. The level in
the cold water tank is controlled by a float valve mechanism which
controls a 4 way auto-shut off valve on the water feed line to maintain a

5 | P a g e
constant level of filtered water. Both models are available with reverse
osmosis (RO) or standard filter (F) versions.

Operation
When installation is complete,
the unit will fill up with water
and shut off when the tanks are
full. Plug the unit in to an outlet
and press the cold/hot faucets
until a steady stream of water
comes out.
Figure 2. Faucet operation
*Make sure the tanks are filled
with water before continuing to
the next step.
Turn on the hot/cold switches
located on the back of the cooler.
Both hot/cold elements will begin
chilling and heating the water
inside the unit. Indicator lights will
also illuminate of the front of the
cooler.

Positioning the Cooler
1) It is not recommended to install this cooler in an area were water
may cause severe or costly damage.

11 | P a g e
2) Do not position the cooler where it can be hit or bumped by
Vacuum cleaners or floor waxing machines. This can cause breaks in
the waterline, connection fittings and compressor tubing.
Water Cooler Connections
When you receive the water cooler, the water connections on

12 | P a g e
the back have of the cooler have tube plugs in them. These tube
sections must be removed before making all your connections. To
remove the tube sections see figure 7 “Disconnect”. The 1/4" plastic
tubing should be used for making the Feed Water and Drain
connections. If hard copper tubing is used for the Feed Water and
Drain connections the bulkhead fittings must be changed to a metal
fitting.
Figure 4. Water Cooler Connections
Feed Water Connections
To connect the feed water, use the supplied self-piercing
saddle valve to connect to the cold water supply line under the sink.

13 | P a g e
Attach the 1/4-inch tubing to the compression fitting on the side of
the valve. Clamp the saddle valve over copper or plastic feed line
(cold water only). Turn the handle on the valve until the needle stem
pierces the tube. Then retract the needle 1-2 turns to start water
flow. See Photo inset.
Drain Connection
(Applies to models with Reverse Osmosis “RO” only)

14 | P a g e
The drain line in the back (Fig. 4) must be hooked to the
drain line ahead of the normal sink water trap.
See Figure 5 below. Place the 2 part drain saddle on the drain pipe
before the drain trap. Allow proper space for the drilling operation.
Tighten the saddle bolts evenly on both sides. Using the opening in
the drain outlet saddle as a guide, drill a 1/4” hole in the drain pipe.
Clean any debris out of the drain saddle connection. Connect the
drain line to the cooler using the 1/4” black tubing supplied.
Figure 5. Drain Connections for “RO” models
EZ Connections
The standard tubing connections on the water coolers are EZ connect fittings. Use
the tubing and follow the instructions below in fig. 7 to make the connections. If you
cut the tubing, make sure it is a square cut, fits squarely in the fitting and seals

15 | P a g e
properly.
Cut the tube square
Cut the tube square. It is essential that the outside diameter is free of score marks and that burrs and
sharp edges be removed before inserting into fitting. For soft thin walled plastic tubing we
recommend the use of a tube insert.
Insert tube
Fitting grips before it seals. Ensure tube is pushed into the tube stop.
Push up to tube stop
Push the tube into the fitting, to the tube stop. The collet (gripper) has stain-less steel teeth which
hold the tube firmly in position while the “O” ring pro-vides a permanent leak proof seal
Pull to check secure
Pull on the tube to check it is secure. It is good practice to test the system prior to leaving site and/or
before use. Push in collet and remove tube
Disconnect
To disconnect ensure the system is depressurized before removing fitting. Push in collet squarely
against face of fitting. With the collect held in this position, the tube can be removed.
Start-Up Flush
Open lower front door to access filter assembly, turn the water
on at the at the water connection, this brings water to the ball valve.

Disconnect the tube from the 2nd stage carbon filter (circle in figure
below) and place a cup or pan right underneath the hole to catch water.
Open ball valve inside the cooler 1/4-turn (handle in line with tube is
“on” and let water flow through filters into the bucket or pan to push out
air and carbon fines. When water runs clear, turn off ball valve and re-
connect the tube to the filter.
Turn on the water to the filter system by opening the ball valve inside the
cooler 1/4-turn (handle in line with tube is “on”). Check all connections
to assure there are no leaks.
Figure. 6 Filter configuration model “F” with cooler door opened
Tank Flush
Flush tanks out by draining all water through the (1) drain
plug located on the back of the cooler and drain water through the

17 | P a g e
dispensing spigots. Fill and empty the tanks 3 times with the filtered
water, this ensures great tasting water. When the tank has filled
again with filtered water the cooler is ready to dispense water. You
may now turn on the Hot and Cold buttons on the back of the
machine. NOTE: You should always turn on the Hot and Cold
elements when they have water inside the tanks.
CAUTION. DO NOT TURN ON HOT OR COLD POWER CONTROLS
YET.
Remove the top cover of the cooler by removing 2 screws from back
of top cover. Pull the cover off, exposing the main tank. This model
uses a mechanical float valve to control flow to the tank. The unit
does not have to be plugged in to start water flow.
Water will flow into the ambient, cold and then the hot tank as well.
Let cooler tanks fill with the filtered water until full - about 1-hours
for the ‘RO’ version, about 10-15 minutes for the ‘F’ version.
Observe the water level when full, and see that water input to the
tank stops when it is full.

Cleaning and Maintenance

18 | P a g e
Sanitize

19 | P a g e
Fill main water tank with water. Add 1-2 teaspoons of liquid
chlorine bleach. Let stand for 5-10 minutes. Drain the water then let
water from filters refill tank and drain a second time. Remember to
drain from dispensing spigots also.
Note: Upon completion of cleaning, wait at least 10 minutes
after the power cord is plugged in before turning on the Hot and
Cold Water buttons.
Filter Replacement

20 | P a g e
The filter elements must be replaced at regular intervals to
maintain the quality of the water.
The H2O-2000F has 3-stages of mechanical filtration. 1st stage 5-
micron sediment filter, 2nd stage activated carbon filter and a 3rd
stage post carbon filter. The filter elements in all stages must be
replaced every 6 months.
The H2O-2000RO model has the 3-stages of filtration plus an
additional Reverse Osmosis membrane filter. The 3 pre filters must
be replaced every 6 months. The Reverse Osmosis membrane must
be replaced every 3 years.
Replacement Procedures, Filtration Versions (F) H2O-2000F
Coolers
a) TURN OFF POWER TO HOT/COLD ELEMENTS
b)Swing open the front hinged cover.
c) Close the ball valve to stop water flow through the filters.
d)Place a towel under the filters to catch water. The filters will
have water in them which will run out when the filters are
unlocked.
e) Twist the filters to remove them from their housings.
f) These filters are disposable, encapsulated filters. Remove and
discard the entire filter body. Replacement filters are sold as a
set:
1st Stage sediment filter
2nd Stage carbon filter
3rd Stage post carbon filter or (optional Nano silver)
f) Twist new filters counter clockwise into the housing brackets.
g) Open ball valve and let water flow through filters, when the
cooler is full empty out the water into a bucket. This will
eliminate the first batch of water which is full with carbon
fines.
h)After the cooler fills up again turn on the power to the cold
and hot tanks. Wait a few minutes to assure there are no leaks
and close the filter door.
