Introduction

Congratulations on your purchase of our revolutionary Bottle-less
Water Cooler! Our coolers are all designed to replace the conventional
5-gallon water bottles while eliminating the hassles of deliveries,
lifting bottles, and by 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.

G3 and G4 Models Both of these models have two temperature
faucets. The cold water is chilled around 44ºF and the hot water is
heated at 180ºF.

All Global Water models are manufactured and marked as “RO” or

“F” assemblies. The “RO” assembly utilizes Reverse Osmosis water

purification technology that produces pure and safe water from city or
well water. The “RO” assembly is comprised of a 5-micron sediment
filter, a carbon (GAC) 10-micron filter, 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 2 carbon filter
system, but not the RO membrane. Therefore, it does not require a
drain line connection.

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.

Please read all the instructions in this manual before operating this
unit.

Receiving the Cooler

Unpacking

Global Water 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 in tact. Look at the back of the cooler to see if the compressor
is secure and has not broken from the mounting. Inspect the filter
system to see that nothing is damaged or dislodged from shipping.

Description (Model G3 and G4)

The Models G3 and G4 both provide water at two temperatures.
The water is dispensed from two spigots—one “hot” and one “cold.” The
assembly drawing is shown in Figure 1 for the G3 and Figure 2 for the
G4. Water flows from the filter system into the top tank, also known as
the cold water tank. This tank then feeds the hot tank that is heated by
internal heaters. The level in the cold water tank is controlled by a float
valve mechanism. This mechanism controls a solenoid valve on the
water feed line to maintain a constant level of filtered water. Both
models are available with reverse osmosis (RO) or standard filter (F)
versions.

The water production flow chart is shown in Figure 3.
