INSTALLATION REQUIREMENTS

Electrical Requirements

A 120-volt, 60 Hz, AC-only 15 or 20 amp fused, grounded electrical supply is required. It is recommended that a separate circuit serving only your hot water dispenser be provided. Use an outlet that cannot be turned on/off by a switch.

Recommended ground method

This appliance is equipped with a power supply cord having a 3 prong ground plug. To minimize possible shock hazard, the cord must be plugged into mating, 3 prong, ground-type outlet, grounded in accordance with all national and local codes and ordinances. If a mating outlet is not available, it is the personal responsibility and obligation of the customer to have a properly grounded, 3 prong outlet installed by a qualified electrician.

Water Supply Requirements

If local codes permit, the hot water dispenser feed line should be connected to the cold water supply line using a saddle valve or another means for providing a 1/4

tube to connect to the dispenser. If a saddle valve is used, do not use a piercing type or 3/16" saddle valve, which reduces water flow and clogs more easily.

IMPORTANT: If local codes do not permit the use of saddle valves, special feed valves can be obtained from your local plumbing supply distributor.

Connection to hot water line is not recommended. Energy will be wasted in heating the water twice and may produce an undesirable taste.

A water filter is recommended if your water supply contains sand, grit or other particles, or has a known taste or odor issue. If a water filter system is used, the water pressure to the hot water dispenser system from the filter needs to be a minimum of 20 psi (138 kPa) for proper operation. If the water pressure to the hot water dispenser system is less than 20 psi (138 kPa), a booster pump can be added.

IMPORTANT: If the water pressure to the hot water dispenser system is less than 20 psi (138 kPa), performance may be affected.

INSTALLATION INSTRUCTIONS

Please complete the “Record your model’s information” section on the front cover before beginning installation.

This hot water dispenser is not a water purifier. Some installations may require a water filtering system to improve the quality of water.

Installing the Faucet

1. Determine where you will install your hot water dispenser. Check below sink to assure that reinforcing ribs, support brackets or cabinet construction will not interfere with faucet.

2. Knock out plug from hole in sink or cut a hole in sink or countertop.

NOTE: It is recommended that only a licensed plumber or professional installer cut an opening in the sink or countertop.

3. Carefully straighten tubing so that it will go through hole in sink or countertop.

4. Remove nut, metal washer and rubber washer from faucet.

Do not remove rubber o-ring in bottom of faucet base.

5. Feed tubing through hole in sink or countertop. Hold faucet in place while installing rubber washer, metal washer and nut on faucet from under the countertop. Securely tighten nut.

WARNING

Electrical Shock Hazard Plug into a grounded 3 prong outlet. Do not remove ground prong. Do not use an adapter. Do not use an extension cord. Failure to follow these instructions can result in death,

fire, or electrical shock.

Installing the Tank

1. Position tank vertically beneath faucet so that the longer copper tube from the faucet reaches the easy-connect fitting on top of the tank.

2. Use a pencil to mark on the wall where the top of tank needs to be located. Set tank aside. Mark a second line 2-1/4" (5.7 cm) below the first line.

IMPORTANT: The tank must be positioned so that the copper tubing and flexible tubing from the faucet does not kink.

3. Position mounting bracket on wall so that bottom of mounting bracket is even with the lower line.

4. Use two screws (and plastic anchors if attaching to dry wall) to fasten mounting bracket to wall. Hang tank on bracket.

IMPORTANT: Do not plug power supply cord into outlet at this time.

5. IMPORTANT: Do not lengthen, twist or tightly bend tubing. Do not use any sealing compounds.

Connect the longest 1/4" copper faucet tube to the rear easyconnect fitting on top of tank. Push tubing straight into fitting as far as it will go. Pull on tubing. The tubing should not come out when properly installed.

NOTE: If you need to remove tubing, push down on collet. Pull tubing out of easy-connect fitting. It is easier to push the collet down if a 1/4" or 7 mm open-end wrench is used as shown.

6. Connect the flexible tube from the faucet to the center tank tube. Make sure the flexible tube does not kink. To avoid kinking, the tube may be shortened.

The center tank tube is not an easy-connect fitting. To connect the flexible tube, use pliers and open the supplied hose clamp. Slide the clamp onto the flexible tube about 2" (5 cm) from the tube end.

7. Push the flexible tube down onto the tank tube as far as it will go. Position the hose clamp so that it is close to the end of flexible tube.

8. Install saddle valve kit or other plumbing parts as needed to connect 1/4" tubing from faucet easy-connect fitting to cold water supply line.

9. Flush line into bucket or pan to remove any debris that may have been trapped in supply line during plumbing connection.

10. Check that water flows freely and that there are no leaks.

11. Connect 1/4" water supply line tubing to faucet copper tubing

with the factory-assembled easy-connect fitting. Push water supply line tubing straight into fitting as far as it will go. Pull on tubing. The tubing should not come out when properly installed.

NOTE: If you need to remove tubing, push down on collet and pull tubing out of easy-connect fitting.

IMPORTANT: For proper operation, do not remove the factory-assembled easy-connect fitting from tube.

12. Open water line to faucet.

Complete Installation

IMPORTANT: The hot water dispenser can be damaged if the following steps are not followed.

NOTE: Do not plug power supply cord into outlet.

1. Turn Temperature Control counterclockwise to “Off” position.

2. Push down and turn the faucet cap clockwise to open faucet.

Hold cap open until water flows from the faucet (about 1 to 1-1/2 minutes).

3. Release faucet cap. Check for leaks.

NOTE: Make sure the Temperature Control is in the “Off” position

before plugging hot water dispenser into power supply. If tank is empty and thermostat is in an “On” position when the power supply cord is connected, the heater will overheat causing an unpleasant taste, black specks in the water, and permanent damage to the hot water dispenser.

4. Once water is flowing from faucet, the water heating tank has been filled with water. Plug power supply cord into grounded 3 prong outlet.

HOT WATER DISPENSER USE

Before first use:

After the tank has been in operation for a minimum of 15 minutes, push and turn the faucet cap and allow water to flow for about 1 minute. Release the faucet cap and allow the water to reheat for about 15 minutes prior to use.

Check that all installation steps were completed.

The Whisper Quiet

System helps to maintain a quiet home environment during the operation of the hot water dispenser.

Te mperature control

The water temperature is thermostatically controlled. It can be adjusted from “Off” to about 190°F (88°C).

To raise or lower the temperature, turn the Temperature Control. The “Max” setting is recommended for best performance. However, under certain conditions, it is possible for the water to boil when the Temperature Control is set at “Max.” If you see any vapor or hear boiling, turn Temperature Control to lower temperature as necessary.

Dispensing hot water

Push down and turn the faucet cap clockwise and hold until desired amount of hot water is obtained. There is a small delay from the time the faucet cap is turned until hot water is dispensed. This delay is normal.

5. Turn Temperature Control clockwise to highest position.

Water in tank will reach maximum temperature in about 15 minutes.

NOTES:

• When water is heating, you may hear gurgling noises coming from the tank.

• There may also be a small amount of spitting or hot water flow from the faucet. This is normal for the initial heat-up of the dispenser.

• The Temperature Control controls tank heater, not water delivery. Rotate Temperature Control clockwise to make water hotter, counterclockwise to lower water temperature.

• Turn Temperature Control to lower temperature setting if you notice vapor or hear boiling noise.

WARNING

Electrical Shock Hazard Plug into a grounded 3 prong outlet. Do not remove ground prong. Do not use an adapter. Do not use an extension cord. Failure to follow these instructions can result in death,
