Installing an Instant Hot Water Dispenser

How to Install an Instant Hot Water Dispenser

The following are helpful instant hot water installation instructions.

  • Turn off the water supply

To begin the installation process, you need to turn off the water supply. After that, unpack the faucet and straighten the copper tubing carefully.

  • Drill a mounting hole

Using a stainless steel bit and a cordless drill, drill a ¾-inch hole into your sink. You can also use a slung buster to cut the hole.

  • Mount the faucet

The next thing you need to do is mount the dispenser faucet. Ensure that the seal sits properly on the unit’s body and that it surrounds your sink’s mounting hole.

  • Tighten the faucet

Now that the faucet is already in place, it’s time you fastened it. Working from under your sink, place the mounting plate on the stud and attach the hex nut. Tighten the nut sufficiently to prevent the faucet from rotating when in use.

  • Mount the dispenser’s hot water tank

For excellent results, mount the hot water tank vertically and in a level location where it’s easy to make plumbing and electrical connections.

Don’t extend electrical or plumbing lines when mounting the tank. If necessary, allow for drainage from under the sink.

Choose a spot under your sink and mount the tank vertically. It should be within easy reach for both electrical and plumbing connections.

Place the tank at least 16” or less of the water lines and 30 inches or less of a grounded outlet.

  • Connect the tubes

And now, it’s time to connect the tubes. Place the connector fitting of the blue tube onto the plastic fitting on the left of your tank. Push it until it clicks perfectly into place.

Slip the white tube over the barbed fitting and connect the clear vinyl tube into the middle fitting.

  • Connect the plumbing

This step involves making tubing connections. Here you’ll find some minor variations depending on the system you’ve purchased.

One thing to note is that when connecting the tubing between components, you need to do it so that it won’t interfere with your cabinet storage area.

Ensure that there are no sharp bends and leave enough length to ease servicing when needed. Once this is done, cut the tubing to lengths of choice and insert them into the connector fittings.

You also need to be careful when cutting copper or plastic tubing by removing all the burrs that might harm the fittings. Insert the tubing into the fittings altogether to avoid future disappointments.

Install the filter and finish the installation

To complete this process successfully, you need to install the head and the unit’s filter bracket.

This should be done carefully to prevent stretching or kinking of the tube when making plumbing connections.

You also need to choose a location that allows for easy replacement of the filter cartridge. Also, don’t mount the filter over any electrical outlet.

Next, mark the locations for the mounting hole and then attach the bracket using the screws provided. Insert the polythene tubing into the filter head’s inlet. Repeat the same process with the filter head’s outlet.

If your dispenser dispenses hot water only, you’ll have to insert its outlet tubing into the connector fitting and the faucet copper tube when installing the filter.

If it’s a hot/cold model, insert the outlet tubing into the quick-connect fitting and the unit’s faucet copper tubing when installing the filter.

After this is done, connect the tube to the compression fitting.

  • Fill the tank

Before plugging the dispenser into the electrical socket, switch on the cold water supply. After this is done, turn the hot tap on to fill the tank.

  • Plug in the tank

Plug in the tank and wait for about 10 to 15 minutes. After this, the water will have reached its target temperature.

Note that some water might drip from the faucet in the first heating cycle, which is quite normal.

  • Adjust the temperature

After 24 hours, it’s time to adjust the temperature of your water. This is because you mustn’t allow the water to boil. Should this happen, water and steam will start dripping from the tap.

You should also know that extended boiling could harm the dispenser.
