Purchasing an Oasis Water Dispenser was a GREAT choice!
This unique design offers the benets of:
• No more struggling to lift heavy water bottles!
• No more spills during water bottle installation!
• No more unsightly bruised or battered recycled water bottles!
Please read the enclosed operating instructions carefully and retain this booklet for future reference. We have carefully
engineered your water dispenser to provide years of enjoyment and trouble-free operation.
• This dispenser is equipped with a grounded power cord plug for your safety.
• Do not operate this (or any other appliance) with a damaged power cord. Be sure that the plug is fully inserted
into the GFCI outlet and that no other appliance is plugged into the same outlet.
• Do not run the power cord over carpeting or other heat insulators, and do not cover it. Avoid laying the cord in
  hightrafcareas,andneversubmergeitinwater.
• Donotuseanextensioncordasitmayoverheat,increasingtheriskofre.
• Ifthesupplycordisdamaged,contactOasisoraqualiedelectriciantoreplaceitbeforepluggingitin.
• Never turn the dispenser upside down. If the dispenser has been resting on its side for a long period of time,
place the it in the upright position for approximately 12 hours before using.
• Forusewithupto5gallon(19liter)waterbottlesorlters.
• Never allow children to dispense hot water without proper and direct supervision.
• Always use known and microbiologically-safe bottled water.
• Keep your dispenser in a dry place away from direct sunlight.
• Do not use this dispenser outdoors.
• Neverputanythingammableclosetothedispenser.
• Leave a minimum clearance of 6 in (15 cm) in back and on both sides of the dispenser for proper ventilation.
• Alwaysinstallyourdispenseronaleveloor.
• Wait 5 minutes before restarting the dispenser after turning it off.
• Always unplug the dispenser before servicing.
• Regular cleaning of your dispenser is required to maintain your warranty.
• Please follow the cleaning instructions outlined in this manual and clean the dispenser every 6 months.
• To provide additional protection from the risk of shock, this dispenser MUST be connected to a ground fault
circuit interrupter (GFCI) outlet at all times. Use of an extension cord will void any warranties.
• This appliance must be grounded. Improper use of the grounding plug can result in a risk of electric shock,
causing serious injury and possibly death.
• This appliance is equipped with a power cord having a grounding wire with a grounding plug and must be
connected into a properly-grounded, polarized outlet.
• Consultaqualiedelectricianifthegroundinginstructionsarenotcompletelyunderstood,orifdoubtexistsas
to whether the appliance is properly grounded. If the wall outlet is a standard, 2-prong outlet, it is your
personal responsibility and obligation to have it replaced with a properly-grounded, 3-prong wall outlet.
• Do not under any circumstances cut or remove the third (ground) prong from the power cord plug.

This model is different from a traditional water dispenser with the water bottle upside down on the top. Instead, the water
bottle is placed upright in the lower cabinet with a pump drawing the water up to the dispenser.
IMPORTANT:
• Clean the top of the water bottle before installing.
• Alwayswashyourhandsrstbeforehandlingthewaterbottlecap.
• Avoid handling the siphon tube. If necessary, remove the tube, wash with soapy water and rinse thoroughly
before reinstalling into the water bottle cap.
• Much like a new refrigerator with an ice maker or water dispenser, it is recommended to run 1 to 2 gal (3.8 to 7.6 L)
ofwaterthroughthesystembeforetherstuse.
IMPORTANT: MAKE SURE THE DISPENSER IS NOT PLUGGED INTO AN ELECTRICAL OUTLET AND THAT BOTH
THE COOLING SYSTEM AND HOT WATER SWITCHES ARE OFF.
1. Open the lower cabinet door.

cap from the mouth of the bottle.
3. Insert the siphon tube into the mouth of the water bottle and press the
waterbottlecaprmlyoverthemouthofthebottle.
4. Slide the siphon tube down until it reaches the bottom of the bottle.
5. Slide the bottle inside the cabinet and close the lower cabinet door.
6. Plug the dispenser into a grounded GFCI power outlet. The water pump will
turnonforseveralminutestollthecoldandhottanks.
7. Once the pump has stopped, place a container under the water dispense
pointandpressthehotwaterdispensebuttonuntilwaterowsfreely.
8. Turn ON both the cooling system and hot water switches located on the
back of the dispenser. If you are not going to use hot water, turn the hot
water switch OFF to conserve energy.
9.Thersttimethedispenserisused,youwillhavetowaitatleast1hourfor

ADDING FILTRATION (OPTIONAL)

10
Formaximumefciencyandperformance,yourwaterdispenserrequirescleaningonaregularbasis(ie.every6
months). Regular cleaning will prevent potential growth of bacteria and will maintain a hygienic environment.
Never use harsh chemicals or abrasive cleaners.
Cleaning the Outside of the Water Dispenser
The outside of the dispenser may be wiped clean with a cleaning solution product or a mild soap and water mixture and
a soft cloth. Rinse thoroughly with clean water and dry.
Cleaning the Drip Tray
The drip tray should be emptied and cleaned regularly to remove spotting and any mineral deposits.
To remove the drip tray, lift the tray upward, dislodging it from the guides. Drain and clean with cleaning solution or a
mild soap and water mixture. For tough deposits, add vinegar and let it soak until the deposits loosen. Then wash, rinse
and dry throughly. Replace the grill on the drip tray and slide it onto the guides.
Cleaning the Condenser
Vacuumorsweepawaythedustfromthecondensercoils.Thiswillimprovecoolingandefciency.
Cleaning The Waterways
IMPORTANT: TURN OFF THE HOT AND COLD WATER SWITCHES BEFORE PERFORMING THIS PROCEDURE.
1. Make sure the power cord is plugged into an electrical outlet.
2.Openthelowercabinetdoor,pullthebottleforwardoutofthedispenserandplaceontheoor.
3. Remove the water bottle cap and siphon tube from the bottle and hang on the hook located on the inside of the
lower cabinet door. Be sure to keep the door open so that the water pump does not run. For bottle-less cleaning, re
peatthisprocedurebutipthewatersupplyswitchto“BOTTLE”duringthisprocedure.
4. Drain the cold reservoir by placing a container under the water dispense point and pressing the cold dispense
buttonuntilwaterstopsowing.Discardwater.
5. Using a clean container, mix 8 cups (2 L) of white vinegar with 8 cups (2 L) of hot water. Place the container inside of
the bottle storage compartment. Insert the siphon tube into the cleaning solution, keeping the container
upright, and close the lower cabinet door. The water pump will start automatically and run for several minutes to
draw the cleaning solution into the dispenser reservoirs. Once the pump has stopped, dispense 0.5 cups (0.12 L) of
water from each of the 2 dispense buttons. Allow the cleaning solution to sit inside the dispenser for 20 minutes.
6. Place a container under the water dispense point and press the hot and cold water dispense buttons
untilthecleaningsolutionstopsowing.Discardcleaningsolution.Thepumpwillcontinuetooperatefor
approximately30seconds,followedbyaashingyellowbottleemptylight.
7. Using a container, drain the remaining cleaning solution from the internal hot and cold tanks by unscrewing the hot
tank drain cap located at the back of the dispenser. Discard the cleaning solution. Re-install the hot tank drain cap.
Repeatforcoldtankdrain.RefertoPage11and12,“DrainingtheReservoirs”fordetailedinstructions.
8. Flush out the cleaning solution by repeating Steps 5-7 using 16 cups (4 L) of fresh hot water (no cleaning solution).
The cleaning process is now complete.
9.ReplacethewaterbottleoriptheswitchbehindtheunitbacktoPOU.(SeeINITIALSET-UP)
NOTE: To conserve energy when not using the dispenser for a long period of time, unplug the dispenser and drain the
reservoirs.
CLEANING AND MAINTENANCE

1. Turn off the hot tank with the red switch in the back of the unit. Dispense hot water from the water dispense point
until the temperature drops to a safe level to avoid the risk of scalding. This will empty the heated water from the
tank and replace it with cool water.
