8.FRefill Fthe Funit Fwith Fwater Fby Ffollowing Fthe F"Startup" procedure in the OPERATION section. - FDispense water out of the unit until the discharge is clear and all deliming solution has been removed and rinsed.

Figure 9. Deliming the Dispenser
5.FTurn Fthe FPOWER FON/OFF F(I/O) Fswitch Fto Fthe FON F(I) position, Fand Fallow Fthe Funit Fto Frun Fat Fthe Foperating temperature for 1-2 hours.
- FWhile Fthe Finit Fis Fat Foperating Ftemperature, Fdispense 1/2 quart (0.4 liters) of the deliming solution through the dispensing port. This exposes the port to the deliming solution. (Safely discard dispensed solution.)
6.FTurn Fthe FPOWER FON/OFF F(I/O) Fswitch Fto Fthe FOFF F(O) position and allow the deliming solution to remain in the unit for a minimum of 4 hours (preferably, over night.)
NOTE: Steps 7 and 8 may need to be repeated until all deliming solution has been removed.
Resetting the High Temperature Safety Switch
The Atmospheric Water Dispenser is equipped with a manually-resettable Fhigh Flimit Fsafety Fswitch Fthat Fprevents Fthe Fwater temperature from getting dangerously high.
If the water inside the unit exceeds 200^ F ( 93^ C), the safety high Flimit Fswitch Fwill Fshut Fthe Funit Foff. FSetting Fthe Fsetpoint temperature over 195^ F ( 91^ C) will cause nuisance tripping of this safety switch. Hatco does not recommend adjusting the setpoint temperature above 195^ F ( 91^ C).
To reset the safety high limit switch after it activates, follow the following procedure.
1.FTurn Fthe FPOWER FON/OFF F(I/O) Fswitch Fto Fthe FOFF position, unplug the unit from the power source, and allow to cool.
- FThe high limit Fswitch Fcannot be Freset until Fthe water temperature drops below 150°F (66°C).
2. FRemove the front shelf by lifting the shelf up and off of the mounting screwheads.
3.FRemove the front panel.
a.FRemove the six screws that hold the front panel in place.
b.FPull the front panel down and off of the dispenser valve. The rubber grommet should stay attached to the hole in the front panel.
4.FPress the small red button on the high limit safety switch until it clicks. The high limit safety switch is located on the water tank, near the left heating element and the bottom of the tank.
•FThe high limit safety switch is now reset.
5.FReinstall the front panel.
a.FPosition Fthe Ffront Fpanel Fback Finto Fplace. FThe Frubber grommet Fshould Fbe Fpositioned Funder Fthe Fdispenser valve.
b.FAlign Fthe six screw Fholes Fon the Ffront Fpanel with the screw holes on the side panels, and secure in position using the six screws removed in step 3.
6.FReinstall the front shelf.
NOTE: If the high limit safety continues to trip, verify the setpoint is 195^ F ( 91^ C) or lower. If the temperature setpoint is above 195^ F ( 91^ C), adjust the setpoint down to an acceptable level. See “Programming the Dispenser” for adjustment instructions.
NOTE: Contact an Authorized Service Agent if the high limit safety continues to trip and the temperature setpoint is 195°F (91°C) or below.

Error Codes
There are four error codes that may show in the display:
E1: Indicates that the display temperature is out of range or display temperature Fprobe Fis Fmalfunctioning. Contact Authorized Service Agent or Hatco for assistance.
E2: Indicates that the control temperature is out of range or control Ftemperature Fprobe Fis Fmalfunctioning. FContact Authorized Service Agent or Hatco for assistance.
E3: Flindicates that the low water probe has not been satisfied. The heating elements are not yet submersed. Check water supply and water shut-off valve.
H2O: Indicates that the inlet water solenoid has been running continuously for an excessive period of time. Check for problems with the water supply or internal water leak.
Water Filtration System
The water filtration system is available for AWD units as an accessory. The water filtration system helps eliminate sediment buildup inside of the tank leading to a longer life of the unit.
Installing a Water Filtration System
Use the following procedure to install a water filtration system.
NOTE: Before beginning installation, verify that the incoming water pressure is between 50–80 psi (345–552 kPa) and the water temperature is less than 100°F (38°C).
1.FShut off the water supply to the unit.
2.FMove the POWER ON/OFF (I/O) switch to the OFF (O) position, and unplug the unit from the electrical receptacle.
3.FThread Fa Fpush-on Ffitting F(included) Fcoated Fwith Fthread sealant into both the inlet and outlet ports on top of the water filtration valve. Tighten securely.
NOTE: To minimize the effects of restricted flow rate, use the least total amount of 1/4" (6 mm) tubing possible. The total length of tubing from the water supply to the hot water dispenser should not exceed 8' (244 cm). One 10' (305 cm) length of 1/4" (6 mm) tubing is supplied with the water filtration system.
4.FMount the water filtration valve bracket to a solid structure in Fa Fconvenient Flocation Fnear Fthe Fhot Fwater Fdispenser (mounting hardware not supplied).
5.FConnect the water supply to the water filtration valve inlet port using the supplied 1/4" (6 mm) tubing.
NOTE: To identify the inlet port, refer to the arrow on the filtration valve between the ports that indicates the water flow direction through the valve.
a.FCut the 1/4" (6 mm) tubing Fto Fthe appropriate Flength.
Make sure to make clean, straight cuts on the tubing for proper connection to the push-on fittings.
b.FConnect one end of the 1/4" (6 mm) tubing to the water supply shut-off valve and the other to the water filtration valve inlet port. An additional push-on fitting is included for the connection between the water supply shut-off valve and the tubing.

6.FConnect Fthe Fwater Filtration Fvalve Foutlet Fport Fto Fthe Fhot water dispenser using the supplied 1/4" (6 mm) tubing.
a.FCut the 1/4" (6 mm) tubing to the appropriate length. Make sure to make clean, straight cuts on the tubing for proper connection to the push-on fittings.
b.FConnect one end of the 1/4" (6 mm) tubing to the water filtration valve outlet port and the other to the hot water dispenser inlet fitting.
- Install Fthe Fwater Ffilter Fcartridge Funderneath Fthe Fwater filtration valve.
a. FInsert the filter up into the valve.
b.FTwist Fthe Ffilter Fclockwise F1/4 Fturn Funtil Fit Flocks Finto position.
8.FMove both the water supply shut-off valve and the water filtration system shut-off valve to the open position, and check for proper operation/leaks.
