** These units have been manufactured with R134a refrigerant. Repairs to the system must be performed by a

Certified Refrigeration Technician only. Always refer to the data plate located on the base of the unit for the
proper refrigerant and charge.

WARNING:

A pressure regulator, such as a slow flow regulator, must be installed in front of the unit’s
water inlet if the water pressure (including any possible pressure spikes) could exceed 100
P.S.I.G. (690 kPA). Failure to comply will void the warranty. The manufacturer accepts no
liability for damage caused by excessive water pressure.

Do not use this drinking water system where the source water is microbiologically unsafe or with water of
unknown quality without adequate disinfection before or after the unit.

evidence of rough handling and concealed
damage. Damage claims should be filed with
the carrier.

Remove the foam packing blocks from between

- Failure to follow these procedures

Remove the access door on the front of the unit by

grasping the handholds on the sides and pulling
off the door. A tap with the palm of your hand
about 6” (15cm) up the side of the cabinet will
allow the door to pop off quite easily. Note
marked area on replacement parts drawing.

Remove the manifold assembly and quad filter

from the mounting brackets and set them outside
the cabinet. There is no need to disconnect the
tubing.

Install filters as stated in filter “Installation and

Service Guide”.

Note: For RO models, do not install the
membrane at this time.

Snap the access door back in place on the front of

the unit.

Note: There are snap points at the handholds
and near the base.

will void the warranty. The manufacturer
accepts no liability for damage caused by
excessive water pressure.

1) Determine the best installation location considering
customer preference, electrical outlet, water line
access, and if applicable, drain locations.

2) The water cooler should be located at least 2” (5cm)
from the wall to assure adequate condenser air
circulation.

3) Locate your best access to the water source. Tap
into the water line with a saddle tapping valve**, a
faucet fitting ball valve, a solder tee, or similar
device.

NOTE: Always check the local plumbing codes
before tapping into a water line. **(See the Saddle
Tapping Valve Installation Instructions in this
manual if applicable. Valves are available from the
Service Department).

Warning: Use only ¼” OD copper tubing to connect

4)

your water supply to the cooler access port. Connect
your water line to the port labeled “water inlet”. The
inlet fittings used on the OASIS
connect fittings. Simply push the tube into the fitting
until it firmly seats in the bottom of the fitting. To
remove the tube, push in the collet and pull the tube
from the fitting. Units are shipped with blue plugs in
each fitting. Remove the plugs in the same manner
described above before inserting the tube. A stop
valve (not included) is recommended near the inlet
connection to the cooler.

The cooler is equipped with a clamp that relieves

5)

stress on the water inlet and drain/product water
fittings when the cooler is moved. The copper tubing
can be coiled and secured in the clamp as shown in
the diagram below. This configuration will help to
reduce the leaks associated with moving a cooler
with plumbing still attached as well as removing the
stress from the fittings.

Reservoir and Filter Flushing procedures previously
outlined must be completed before cooler is
installed.

NOTE:

plumber to install cooler; AR, GA, MA, MI, OK, RI, SC,
SD, TX, VT and WI.
CA, KS, MN, NM and OR allow for a state-registered
installer or contractor as well.

WARNING: A pressure regulator, such as a
slow flow regulator, must be installed in front
of the unit’s water inlet if the water pressure
(including any possible pressure spikes) could
exceed 100 P.S.I.G. (690kPA). Failure to comply

The following states require a licensed

RO Cooler only - complete instruction 6,

6)

Filter models - proceed to instruction 7.

Connect a ¼” OD copper tube to the drain fitting
located on the back of the unit. This tube should
be routed to the most convenient drain location
such as a sink drain. (See the Drain Clamp
Assembly instructions in this manual if
applicable). Drain applications routing tubing
from a cooler to the ceiling and then into a drain
is acceptable. Some reduction in membrane
productivity may occur, however, depending on
the height of the ceiling and the source water line
pressure. Some local plumbing codes require
an air gap to be installed between the cooler and
the drain connection. Air gaps are available
from the service department. Check your local
plumbing codes to assure compliance.

To speed up the process of priming the unit, you

7)

may wish to pour 4 gallons (15 liters) of filtered
water into the reservoir. To do so, first remove
the cooler top and remove the reservoir lid (see
“Reservoir Replacement Procedure” under the
service information for the easiest method).
Replace the lid and top after pouring the water
into the reservoir.

Check the available power supply against the

8)

water cooler data plate to assure proper
electrical service. The voltage specification is
115v + 10% and voltage outside of this
specification will affect cooler performance and
could permanently damage the refrigeration
system.

Verify that the hot tank switch is in the “off”

9)

position. Plug power supply cord into receptacle.

Turn on water supply to cooler.

10)

Open each faucet until water flows freely.

11)

On hot tank models, turn on the hot tank by

12)

depressing the switch toward the reset position.
The switch is located inside the access door,
mounted on the column support.

CAUTION: WATER FROM HOT FAUCET CAN
SCALD.
DO NOT USE THE FIRST THREE
RESERVOIRS OF WATER.

SERVICE INFORMATION & GUIDELINES

Lubrication

A)

This unit is equipped with a hermetically sealed
compressor and no periodic lubrication is necessary.
Replacement filter/RO cartridge o-rings should be
lubricated with Dow Corning® Compound 111 or
equivalent, when they are installed.

B)

Periodic Maintenance

The black static condenser on the rear of the

1)

unit must be kept clean of dirt and lint. Visually
inspect every 3 months.

Cleaning Procedure:

Unplug the cooler.

a)

Clean condenser with a small stiff non-wire

b)

brush.

Periodic replacement of the filter/RO cartridges

2)

will be required. The frequency of the change
will be determined by the attributes of the source
water. Foul taste or odor may occur if filters are
not changed at proper intervals.

Filter change procedure:

Prepare a spare filter/RO vessel set in your

a)

shop. Clean and sanitize the vessels and
then install the replacement cartridges per
the instructions in the filter “Installation and
Service Guide”. Then continue with the
following flushing and installation
procedures.

On filtration versions, run a ¼” OD tube from

b)

the blue collet port of the manifold to an off­center port on the quad lead filter vessel.
Run a ¼” OD tube from the center port to
the nearest drain location. Plug the other
off-center port. Connect a ¼” OD tube from
the water supply to the white collet on the
manifold. Turn on water and flush filters for
10 minutes. Disconnect tubing and plug the
ports. Take this vessel set to the installation
and install it in place of the existing vessel
set. Take the old vessel set back to the
shop for refurbishment.

On reverse osmosis versions, run a ¼” OD

c)

tube from the blue collet port of the manifold
to an off-center port on the quad carbon filter
vessel. Run a ¼” OD tube from the center
port to the nearest drain location. Plug the
other off-center port. Connect a ¼” OD tube
from the gray collet elbow to the yellow collet
elbow. Connect a ¼” OD tube from the
water supply to the right hand white collet
port on pre-filter side. Plug the red collet
port and the smartap port located behind
pre-filter inlet and outlet ports. Turn on
water and flush pre-filter and carbons for 10
minutes. Turn off water. Remove
membrane vessel and discard water. Insert
membrane per “filter installation” on page 2
of the filter “Installation and Service Guide”.
Connect ¼” OD tube from red collet port to
drain. Turn on water and flush 3-4 minutes.
Disconnect tubing used for flushing and plug
all ports.

Reservoir cleaning and sanitizing should be done

3)

each time the filters are changed. Prepare a
spare reservoir assembly following the “Reservoir
Flushing” procedures outlined in the filter
“Installation and Service Guide”. On hot models,
inspect the o-rings in the hot tank fitting and the
reservoir which seal the hot tank opening. These
should be replaced if they show signs of a
flattened diameter.

Reservoir Replacement Procedure:

Remove the top by lifting it up and pressing

a)

in on the cabinet back about 4” (100mm) in
from the side and 2” (5mm) down from the
top.
