Fisher & Paykel dishdrawers have a different installation procedure than traditional front-loading dishwashers because dishdrawers install into a cabinet and not under a countertop. Dishdrawers open like a drawer and you place the dishes inside. This is especially handy in smaller kitchens or kitchen built in the 1950s which don't have space for a dishwasher. Even though the installation process is slightly different, dishdrawers require a drain connection, water connection and electrical connection just like traditional front-loading dishwashers.
Measure your cabinetry with a tape measure before purchasing your dishdrawer to ensure the Fisher & Paykel dishdrawer will fit into your cabinet. The size of your cabinet determines the size of the dishdrawer you can install.
Check with local building authorities to determine if you need a permit. In most cases, you need a permit if you need to modify your plumbing and electrical services. However, if you are installing the dishdrawer as a replacement unit and connecting to existing plumbing and electrical connections, you will not require a permit.
Contact a licensed plumber and have him connect a tee-junction to your hot water line along with a shut-off valve. This will allow you to connect a hose between your dishdrawer and your hot water line. Also, have your plumber install a waste tee onto your sink's drain. You need a waste tee installed so you can connect the drain for your dishdrawer. If you are confident and understand plumbing, you can tackle these tasks on your own. Make sure you follow all local building codes when installing the water and drain lines.
Contact a licensed electrician and have him install a 110-volt GFI (ground fault interruption) electrical outlet under your sink. He will place it in an area where it will not come into contact with water. If you feel confident running an electrical cable from your sink to your breaker box and then installing an electrical outlet, you can tackle the task yourself. Follow all local building codes when installing the outlet.
Drill a 1 ½-inch hole with a hole saw between the cabinet for the dishdrawer and the under-sink cabinet. This allows you to run your water, drain and electric connections.
Locate the two holes in each corner on the sides of the dishdrawer. Slide the two tabs on the end of the side-mounting brackets into the holes and snap the brackets into place with a screwdriver. Each bracket is labeled with an "A" or "B." Looking at the front of the dishdrawer, the "A" brackets go in the upper right corner and the lower left corner. The "B" brackets go in the upper left corner and the lower right corner. The mounting brackets are supplied with the dishdrawer.
Unroll the moisture barrier. It is made of felt and has a self-sticking adhesive on one side. The adhesive has a plastic cover over it. Pull the cover off the adhesive and stick the barrier inside the cabinet where you are mounting the dishdrawer. Place the sticky side against the inside top of the cabinet. This acts as a moisture barrier between the dishdrawer and the cabinet.
Place the dishdrawer in front of the cabinet hole and route the water line, drain hose and electrical cable through the 1 ½-inch hole you drilled in the side of the cabinet. Lift the unit up and slide it into the cabinet. As you do this, have a second person pull the hose through the hole so the hoses don't kink.
Open the drawer half way and pry the plastic grey plugs from each of the four front corners of the dishdrawer. The plugs are located inside the unit. Removing the plugs gives you access to the side-mounting brackets from inside the unit. With a Phillip's screwdriver, secure a screw through the side-mounting brackets and into the trim of the cabinet. The mounting screws are supplied with the dishdrawer. Once complete, press the grey plugs back into place.
Secure the drain hose to the waste-tee. Use the supplied drain hose joiner to complete the connection.
Thread the water supply hose onto the threaded shut-off valve. Turn on the shut-off valve and check for leaks. If you have any leaks, tighten the hose with a pair or channel locks.
Plug the dishdrawer into the electrical outlet.
