PWC – 500/1000/1010/1500 PureWaterCooler • Faucet Repair Cont. 6.4 Lift out the lever assembly. Obtain a new lever assembly and install in the faucet base. Hand tighten the lever assembly securely. 6.5 Fill the cooler with water and check for leaks (shown with front panel removed) Button Seal Note: When removing and replacing the lever assembly, make sure the rubber seal and the lever are connected together.
PWC – 500/1000/1010/1500 PureWaterCooler 7. Hot Tank Reset Button 7.0 Observe that there are two circular sensors attached to the hot tank. The lower one is the main controller at 82 ºC and the upper senor is the over-temp cut off. The power switch for the hot tank (at the back of the cooler) should not be turned on until water can be dispensed from the hot spigot. If the hot power is turned on without water in the hot tank the heating element will over heat.
PWC – 500/1000/1010/1500 PureWaterCooler 8. Remove/Replace Thermal Sensor 8.0 The hot tank thermal sensors are located on the outside of the hot tank. There are two thermal sensors. The sensor located lower on the hot tank controls the daily operation of the heating element. The upper thermal sensor is an overheat safety switch and cuts power to the hot tank should a malfunction occur and the tank starts to overheat. 8.1 Unplug cooler from power source for this operation. 8.
PWC – 500/1000/1010/1500 PureWaterCooler • Remove/Replace Thermal Sensor cont. 8.4 There are (2) thermal sensors attached with screws to the hot tank. The lower sensor automatically turns the heating element on and off to maintain the water at 180 ºF. The upper sensor is the over temperature sensor. This sensor activates if the temperature on the tank goes over 212 ºF. If this sensor is activated due to a overheat condition, it will cut the power to the heating element.
PWC – 500/1000/1010/1500 PureWaterCooler 9. Cold Tank Temperature Adjustment 9.0 The cold water temperature adjustment is located on the back of the cooler on the right side. An expansion tube senses temperature in the cold tank and open and closes the thermostat. 9.1 The cold adjustment is a shaft with a screw driver slot on the end. 9.2 To make the water colder, using a screw driver, rotate the shaft clockwise. For warmer water rotate the shaft counter clockwise. There are stops on the adjustment shaft.
PWC – 500/1000/1010/1500 PureWaterCooler 10. Draining Cooler Tanks Completely draining the tanks is required when shipping the cooler or when one the of the tanks needs replacing. This procedure will allow you to remove all the water from the cooler. 9.0 Hot and Cold Tank Drain: Using a flat head screw driver, pry the hot tank plug out until you can grasp it with your fingers. 9.1 Remove the plug with fingers. Water will pour from the port 9.
PWC – 500/1000/1010/1500 PureWaterCooler 11. Remove/Replace Cold Tank Sensor 11.0 The cold tank sensor is extremely reliable and rarely needs replacing. Its function is to control the cold water temperature by turning the compressor on or off as needed. 11.1 Remove the top cover of the cooler (sec. 3) 11.2 Remove the float assembly )sec. 4) 11.3 Remove the silicon rubber sealing ring 11.4 Remove the silicon over flow tube 11.

PWC – 500/1000/1010/1500 PureWaterCooler • Remove/Replace Cold Tank Sensor cont. 11.9 Remove cold sensor switch and sensor tube from cooler 11.10 To remove the sensor tube, carefully pull the sensor out of the copper tube at the bottom outside of the cold tank 11.11 With new cold sensor, carefully install sensor tube into copper tube at bottom of cold tank. 11.12 Install the sensor switch using (2) screw to cooler cabinet. 11.13 Adjust sensor tube so it is routed close to the outside of the cold tank.
PWC – 500/1000/1010/1500 PureWaterCooler 12. Sanitization Procedure The sanitization procedure is performed to reduce/eliminate any bacteriological growth in the cooler tanks and dispensing plumbing. Bacteriological growth can be the cause of some taste and odor in the water. The procedure is as follows: • • • • • • • • • • Mix 1 teaspoon of common household bleach (5.25%) in 2 gallons of clean water. Unplug the cooler from the power source. Drain all water from the cooler tanks.
PWC – 500/1000/1010/1500 PureWaterCooler 13. Trouble Shooting Water not cold from cold tank (Water dispenses from spigot but is not cold) Solution Possible causes 1. Cooler not plugged in . Make sure power cord is plugged into wall socket 2. Power switch not on Make sure cold power switch on the back panel is on. 3. Adjust temperature control The thermostat temperature control adjustment is located on the back of the cooler. (see section 9) 4.
PWC – 500/1000/1010/1500 PureWaterCooler 13. Trouble Shooting Cont. No Hot Water from Hot Tank Possible Causes Solution 1. Cooler not plugged in Make sure power cord is plugged into wall socket 2. Power switch not on Make sure Hot power switch on back panel is on and hot power light on front is illuminated 3. Electrical terminal disconnected Check to see that both wires are connected to the heating element terminals. These are located at the bottom of the hot tank 4.
PWC – 500/1000/1010/1500 PureWaterCooler 13. Trouble Shooting Cont. No Hot Water from Hot Tank Possible causes Solution cont. . 5. Thermal sensor failure The thermal sensors are attached to the hot tank. The upper sensor is a 96 ºC sensor and functions as an over heat safety. The lower sensor is a 82 ºC sensor and controls the heating element function. The lower sensor would be the problem if there was no hot water. To see if the sensor is functioning properly, first unplug the cooler from the wall.
Trouble Shooting Cont. No Hot Water from Hot Tank cont. An indicator of a hot tank problem can also be the lights on the front control panel. Below is a table of trouble shooting help.
PWC – 1000/1010 PureWaterCooler 14. Model PWC-1010 The model PWC-1010 has room and cold temperature water dispensed from the two spigots. Nearly all functions and construction of the PWC-1010 cooler are the identical to the PWC-1000 (hot and cold) cooler except as follows: 1. There is no heating element in the room temperature holding tank 2. There are no power switches on the back of the cooler 3. The cold power (compressor) turns on as soon as the cooler is plugged in. 4.
