About the Primo 601376/601376-C
The Primo 601376/601376-C is a hot-and-cold point-of-use water cooler certified under the ENERGY STAR program. It draws water from a plumbed (point-of-use) water line.
It dispenses hot and cold water. Certification testing recorded cold water at about 48 °F (9 °C) and hot water at about 166 °F (74 °C). Water is chilled and heated in internal storage reservoirs, so a supply is ready on demand.
Rated on-mode energy use is 0.64 kWh per day — about 234 kWh a year. That is lower than 62% of the 100 hot and cold coolers in our database.

Safety information
- Hot water can cause severe scalds. This model dispenses hot water at about 166 °F (74 °C), hot enough to burn skin almost instantly. Keep any child-safety lock on the hot tap engaged and do not let children use the hot tap.
- 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.
- Do not switch on the heater until the hot tank is full of water — heating an empty tank can damage the heating element.
- Connect the cooler only to a potable cold-water supply, through an accessible shutoff valve.
Installation and first-time setup
- Choose the location
Place the cooler on a level, solid floor near a grounded outlet and a cold-water line, 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.
- Connect the water supply
Run a 1/4 in. food-grade supply line from a cold-water shutoff valve to the cooler inlet, install any filter cartridges as the manual shows, then open the valve slowly and check every fitting for leaks. A leak detector or automatic shutoff under the cooler is inexpensive insurance.
- Fill the hot tank
Before turning on the heater, press the hot tap until water flows steadily. This confirms the hot tank is full.
- Power on
Plug in the cooler and switch on the cooling and heating switches if your model has them. Allow time for the first cool-down and heat-up before drawing water.
Using your water cooler
Dispensing water
- Cold tap: chilled water, about 48 °F in certification testing. After heavy use, give the reservoir a little time to recover.
- Hot tap: about 166 °F — suitable for tea, instant soup and oatmeal. Dispense slowly into a heat-resistant cup; if the tap has a child-safety lock, re-engage it afterward.
- Place cups on the drip tray and avoid touching tap nozzles with the cup rim or your hands.
Filters
Replace filter cartridges on the schedule in the manual or sooner if flow slows or taste changes. Flush new cartridges as directed before drinking the water.
Saving energy
- Keeping the hot tank hot is the largest load on a hot-and-cold cooler. If your model has a separate heater switch, turn it off overnight, on weekends or whenever hot water is not needed.
- 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. |
| Every 3 months | 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. |
| As scheduled | Replace filter cartridges and record the date on the cartridge or a label. |
| Every 6 months | Unplug and vacuum or brush dust from the condenser coils at the back. |
| Before a long absence | Unplug the cooler, let the hot tank cool, 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. |
| Water is not hot | Heater switch off; hot tank not filled before switching on; child lock not fully released. | Turn on the heater switch, dispense from the hot tap until water flows, and press the lock as the manual shows. If your model has a thermal reset, see the manual. |
| No water or slow flow | Supply valve closed; clogged filter; kinked supply line. | Open the valve, replace the filter and straighten the line. |
| Leaking | Loose fitting on the supply line or filter; drip tray full. | Unplug, empty the drip tray and tighten fittings with the supply valve closed. Call for service if water collects under the cabinet. |
| Odd taste or odor | Cooler due for sanitizing; filter overdue. | Sanitize the cooler and change the filter. |
| 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. |
Energy use and running costs
The Primo 601376/601376-C is rated at 0.64 kWh per day in on mode under the ENERGY STAR test method. Over a full year of continuous operation that is about 234 kWh, or roughly $39.71 per year at $0.17 per kWh ($3.31 a month).
Its daily energy use is lower than 62% of comparable coolers in our database.
Most of a hot-and-cold cooler's energy goes into keeping the hot reservoir at temperature. Switching the heater off when hot water is not needed — overnight and on weekends in an office — is the single biggest saving.
