About the Crystal Mountain GLED2WTW1AC
This guide covers the Crystal Mountain GLED2WTW1AC, a cold-and-room-temperature bottom-load water cooler listed as ENERGY STAR certified. It draws water from a bottom-loading bottle.
It dispenses cold and room-temperature water (ENERGY STAR calls room-temperature water "cook" water). Certification testing recorded cold water at about 45 °F (7 °C). Water is chilled in internal storage reservoirs, so a supply is ready on demand.
Rated on-mode energy use is 0.1 kWh per day — about 37 kWh a year. That is lower than 100% of the 23 cold and room-temp coolers in our database.

Safety information
- Plug the cooler into a grounded three-prong outlet. Do not use an extension cord or adapter, and keep the cord and plug away from spilled water.
- Unplug the cooler before cleaning, sanitizing, moving it or changing filters.
- Use the cooler indoors only, upright on a level floor, away from direct sunlight and heat sources.
Installation and first-time setup
- Choose the location
Place the cooler on a level, solid floor near a grounded outlet, out of direct sunlight (which encourages algae growth) and away from heaters. Leave a few inches of space behind and beside the cabinet so the condenser can release heat.
- Let it stand
If the cooler was transported on its side, stand it upright and wait before plugging it in so the compressor oil can settle — check the manual for the exact time, which can be up to 24 hours.
- Clean before first use
Wipe the reservoir area and taps, then flush the system as the manual directs by dispensing and discarding water from each tap.
- Load the bottle
Open the lower cabinet, remove the bottle cap, insert the probe assembly fully into the bottle and slide the bottle into place. The pump fills the internal reservoir automatically.
- Power on
Plug in the cooler and switch on the cooling switch if your model has them. Allow time for the first cool-down before drawing water.
Using your water cooler
Dispensing water
- Cold tap: chilled water, about 45 °F in certification testing. After heavy use, give the reservoir a little time to recover.
- Room-temperature tap: unchilled water for taking medication, drinking without a chill, or cooking.
- Place cups on the drip tray and avoid touching tap nozzles with the cup rim or your hands.
Changing and storing bottles
Replace the bottle when the cooler signals that it is empty or water stops flowing. Store spare bottles indoors, out of sunlight and away from cleaning products, gasoline or paint — plastic bottles can absorb odors. Wipe the bottle neck and the probe before each change.
Saving energy
- Keep the condenser coils at the back free of dust and leave space around the cabinet for airflow.
- Avoid placing the cooler in direct sun or next to heat-producing equipment.
Care and maintenance
| When | What to do |
|---|---|
| Weekly | Empty and wash the drip tray; wipe the taps and cabinet with a damp cloth. |
| Each bottle change | Wipe the probe and tubing with a clean, damp cloth before inserting it into the new bottle. |
| Every 3 months (or each bottle change, if the manual says so) | Unplug the cooler and clean and sanitize the reservoirs and water path with a food-safe sanitizer as the manual directs, then rinse thoroughly by dispensing several quarts from each tap. |
| Every 6 months | Unplug and vacuum or brush dust from the condenser coils at the back. |
| Before a long absence | Unplug the cooler, drain the reservoirs as the manual describes and leave the unit dry. |
Troubleshooting
Most water cooler problems come down to power, the water supply or cleaning. Try the checks below first, and consult your manufacturer's manual for model-specific indicators.
| Problem | Possible cause | What to try |
|---|---|---|
| Water is not cold | Cooling switch off or unplugged; recently installed; heavy use; blocked airflow or hot room. | Check the plug and switch, allow time to recover after heavy use, and clear space around the coils. |
| No water or slow flow | Empty bottle; probe not fully inserted; pump not running. | Replace the bottle and reseat the probe; listen for the pump after a bottle change. |
| Leaking | Probe not sealed; drip tray full; loose internal fitting. | Unplug, empty the drip tray, and reseat or replace the bottle. Call for service if water collects under the cabinet. |
| Odd taste or odor | Cooler due for sanitizing; bottle stored near chemicals or in sunlight. | Sanitize the cooler and store bottles properly. |
| Humming, clicking or gurgling | Normal compressor and fan sounds. | No action needed. Loud rattling usually means the cooler is not level or is touching the wall. |
| Pump runs continuously | Bottle empty; probe not sealed; air leak in the line. | Replace the bottle and reseat the probe. If the pump keeps running, unplug the cooler and consult the manual. |
Energy use and running costs
The Crystal Mountain GLED2WTW1AC is rated at 0.1 kWh per day in on mode under the ENERGY STAR test method. Over a full year of continuous operation that is about 37 kWh, or roughly $6.21 per year at $0.17 per kWh ($0.52 a month).
Its daily energy use is lower than 100% of comparable coolers in our database.
Without a hot reservoir to maintain, this cooler's energy goes almost entirely to chilling water, which keeps running costs low. Clean coils and good airflow keep it that way.
Frequently asked questions
How much electricity does the Crystal Mountain GLED2WTW1AC use?
