Before starting, turn off the water supply. Then unpack the dispenser faucet and carefully straighten the copper tubing. Keep in mind that each model contains slightly different components. For example, only the Series 1100 models have the filter as a standard component.


You can choose either the HC or HC1100 models, offering both hot and cool drinking water..or the GN, GN1100, 770 or 990 models, dispensing hot water only.Select the model that applies to you to learn how to install your hot water dispenser.


You'll first mount the dispenser faucet. Make sure the seal is properly seated on the dispenser/valve body and that it surrounds the sink mounting hole.If you are installing Model GN1100, H990 or HC 1100, continue on to step 04a.If you are installing Model GN or HC, skip to step 04b.If you are installing Model H7700, skip to step 04c.


Working from under the sink, place the semi-circular mounting plate on the threaded stud.Attach the hex nut, then, using the tool provided, tighten the nut sufficiently to keep the faucet from rotating.


Remove the wing nut from valve body.For a 1-1/4" sink hole, stack the 1-5/8" rubber washer, the 1-5/8" stainless washer or the 2-1/4" colored washer.For a sink hole greater than 1-1/4", stack the 1-5/8" rubber washer with the 2-1/4" stainless or the 2-1/4" colored washer.Have a helper hold the head assembly from above and slide the 2-1/4" fiber washer into place under the sink and tighten the assembly using the plastic wing nut.


Place the dispenser head with #10-24 mounting screw and gasket attached down through the mounting hole.Then, while a helper holds the dispenser head in place above the sink, align the semi-circular metal mounting washer over the head of the mounting screw under the sink.Secure the mounting washer by tightening the screw.


The next step is to mount the hot water tank. Mount it vertically and level in a location where the plumbing and electrical connections can be made. Do not extend plumbing or electrical lines. Also, allow for drainage from the underside if necessary.

Select a spot under the sink to mount tank vertically within reach of both plumbing and electrical connections. The tank should be within 16 inches or less of faucet water lines and within 30 inches or less of a standard grounded outlet. While holding the tank in place on the spot selected for installation, use a pencil to mark locations for 2 hanging screws. Drill two eighth-inch holes for the wood screws. Secure the tank to the wall.



Install the head and filter bracket assembly in such a way that all plumbing connections can be made without stretching or kinking the tube. Also, make sure the mounting location allows for the filter cartridge to be replaced. The filter should never be mounted over an electrical outlet.

Mark the mounting hole locations and attach the bracket with the screws provided. If you wish to redirect water discharge when the filter is replaced, slide one end of the 6" tube over the vent line that opens when the cartridge is removed..and attach the other end to the hole on the head & bracket assembly.

1-2 ounces of water is discharged during cartridge replacement - this 6" gray tubing redirects it downward where it is more easily captured in a pan or towel.


Next, make the plumbing connections. This involves making tubing connections and here you'll find a couple minor variations depending on which System you've purchased. But first let's go through some guidelines that should be followed regardless of system.Make sure that when routing the tubing between components, you keep it from interfering with the cabinet storage area. Avoid sharp bends, leave extra lengths for ease of servicing, then cut the tubing to desired lengths and insert them completely into the quick-connect fittings. When cutting either plastic or copper tubing, care must be taken to remove all burrs that may harm the quick connect fittings and be sure to insert tubing completely into the quick connect fittings. To remove, depress the release ring and gently pull out tubing.


If you are installing the F-201 filtration system: Completely insert the 3/8" polyethylene tubing into the inlet side of the filter head. Do the same with a similar length of tubing into the outlet side of the filter head.If you are installing Model GN1100, continue on to step 10a.If you are installing Model HC1100, skip to step 10b.For all other models, skip to step 11.


If you're installing the GN 1100 model, you'll now insert the outlet tubing into the quick-connect union fitting…and then insert the dispenser faucet copper tube - marked with white tape - into the quick-connect union fitting.


To install the Model HC 1100 model, insert the tubing from the outlet side of the filter head into the quick-connect "Y" fitting. Then insert both dispenser faucet copper tubes - one white taped, one untaped - into the "Y" fitting.


To connect the polyethylene tube from the input side of the filter to your cold water supply line, use the brass nut, ferrule and tube insert supplied. Slide the nut and ferrule over the tube, and push in the tube insert. Then insert the tube into the standard compression fitting, and tighten. Do not plug in the unit yet.


Without plugging the unit into the electrical outlet, turn on the cold water supply. Then turn the hot faucet handle on and hold it to fill the tank. The tank will fill up and cold water will come out of the faucet. Run the faucet for 3 minutes to flush the system, making sure all connections are watertight.


Now you can plug in the tank. It will take 10 to 15 minutes for the water to reach its target temperature. YOU MAY EXPERIENCE SOME WATER DRIPPING FROM THE FAUCET DURING THE FIRST HEATING CYCLE. THIS IS NORMAL. SIMPLY TURN ON THE HOT WATER FOR 15 SECONDS AND ALLOW TO REHEAT.


You're ready to go, with near-boiling, hot water at your command. After 24 hours of operation, you may want to adjust the temperature of your hot water. The thermostat is preset at the factory at approximately 200°F. Care must be taken not to allow the water to boil. If this happens, you will experience steam and water dripping from the faucet and extended boiling may harm the unit. Simply adjust the temperature by 1/2 dial-mark increments clockwise to increase the temperature and counterclockwise to decrease the temperature.
