I. Common Oasis Water Cooler Repair and Troubleshooting Information

    I. Common Oasis Water Cooler Repair and Troubleshooting Information

    #1 Most Common Cause of Water Cooler Problems:
    According to Oasis technical support, the most common cause of water cooler problems is a dirty condenser. Oasis recommends taking a look at the condenser and making sure it is clean. A dirty or clogged condenser can affect the thermostat, resulting in water that is either to warm, too cold or frozen. The condenser is located on the top right side of the water cooler. One way to check if the condenser in your water cooler is clogged is to put your hand on top of the cooler. If the cooler is warm to the touch, then that is an indication that the condenser is dirty.

    How to Clean Water Cooler Condenser

    How to clean the condenser:
    To remove dirt and lint from the condenser, disconnect the power supply cord from the electrical outlet, and then clean the condenser with a small stiff non-wire brush or vacuum cleaner attachment brush.

    Oasis recommends inspecting the condenser every 3 months.

    Why is the water cooler still not cooling (condenser is clean and functioning)?
    The fan and the compressor can also cause the water cooler to not properly cool. Make sure both the fan and the compressor are functioning properly.

    • If both the compressor and the fan are not running, the thermostat or a bad service cord could be the culprit. Oasis suggests making sure the two thermostat leads are connected to the inside gold colored tabs. If connected to the silver or outside lead, the breaker will blow because this is the ground terminal.
    • If just the compressor is not functioning, the cause could be open windings, relay, overload, and or start/run capacitors.
    • If both are running and the water cooler is still not cooling, contact Oasis tech support for more help.

    When does the water control cartridge need to be replaced?
    The top 3 signs that the water control assembly cartridge needs to be replaced:

    • Water won’t shut off (water dribbles out of bubbler head)
    • Water leak from unit going to the floor
    • Water pressure will not adjust

    II. General Oasis Unit Questions

    II. General Oasis Unit Questions

    Where can I find the model number of my Oasis drinking fountains?
    Oasis model numbers are found on the bottom of the drinking fountain, water cooler, or bottle filler. The model number can be found most often on a sticker located on the bottom of the frame on the outside.

    Is there an antimicrobial option for water cooler finishes?
    Yes, some Versacooler units are available with antimicrobial parts. The antimicrobial parts available include the basin, front nose, and buttons. Note that the standard bubbler and bubbler button (when manual) that come with all units are antimicrobial.

    Are Oasis units available in heavy duty stainless steel?
    Yes. Some versions of Oasis water coolers are available with heavy-duty, 14-gauge stainless steel. Note that this option is only available for vandal resistant style units.

    In what configuration does an Oasis bi-level unit come in terms of set up, and can it be installed in the opposite way?
    Oasis split level (also known as bi-level) units arrive in packaging ready to be set up with the right side high, left side low. When bi-level units include a bottle filler, the bottle filler comes ready to be installed on the lower left unit.

    These units can be converted to right side high, left side low with no additional parts needed. The changes that need to be made to install the unit in this configuration include:

    1. Moving the panel from one side to the other to hide the hole in the panel.
    2. The waste or drain tailpieces also need to be switched.

    Note: the compressor must stay on the right side no matter which configuration is chosen.

    Does Oasis have retrofit bottle filler kits?
    Yes. There are two add-on bottle filler options: a manually activated retrofit bottle filler (Oasis model PWSBF) and a sensor activated retrofit bottle filler (Oasis model PWEBF)

    Which water coolers can be retrofit with an Oasis bottle filler?

    Oasis Units: Oasis PG8AC, P8AC, and P8AM model water coolers (and variations thereof) can be made into bottle filler water cooler combination units.

    Sunroc Units: Oasis bottle filler retrofit kits can also fit Sunroc ADA8AC units as well as some Older Sunroc ADA series units (ex: Sunroc model number: ADA8)

    *Note that when retrofitting an older style Sunroc, you need an additional gasket for the Oasis retrofit kits. The gasket is Oasis model: 036689-101.

    Elkay Units: Oasis bottle filler retrofit kits can also fit Elkay Series EZ or LZ units. When retrofitting Elkay EZ or LZ units with an Oasis bottle filler, you must buy an additional gasket. The gasket is Oasis model: 036689-201.
