Installer Tip:

Shut off main water supply before installing new faucet.
Step 1a: Installing the easy install assembly (without escutcheon) Shut off the water supply. Remove the old faucet. Clean the mounting surface.
Check for the proper thickness of the sink or countertop. Insert the base (a) into the sink or countertop. If your model does have a escutcheon, skip to step 1 b.
NOTE: “Front” on the base (a) must face the front of the sink or countertop. The two mounting plates (b)b) on the base (a) must be loose movable during the installation of the base (a).
Step 1b: Installing the easy install assembly (with escutcheon) Place the escutcheon (C) and the gasket (D)D) on the s or countertop. Insert the base (a) into the escutcheon (C). Note: If the surface is uneven, use silicone under the gasket (D).
NOTE: “Front” on the base (a) must face the front of the sink or countertop. The two mounting plates (b)b) on the base (a) must be loose movable during the installation of the base (a).
Step 2: Installing the easy install assemblyKraus KPF-2631 Single

assembly Press the base (a) so that it can not move, then turn the screw with the provided hex wrench (C, HEX: 6.0mm) clockwise, as shown in Fig 1. When the mounting plates (b) make contact with the sink (1), continue to turn the screw with the provided hex wrench (C, HEX: 6.0mm) clockwise, as shown in Fig 2, until the base (a) is completely tightened and secured, as shown in Fig 4.

Commercial Style Kitchen Faucet - counterweight Install the weight clip (G) at the point of the hose marking “weight here”. Insert the weight (F) onto the weight clip (G) by sliding it down onto the weight clip (G).
Step 5: Connect waterlines to main valve Attach waterlines to angle stops and tighten until snug. Turn on angle stops and check for leaks (DO NOT TURN FAUCET ON).
NOTE: Please make sure filter washers are installed before connecting to the main valve.
Step 6: Flush faucet NOTE: Please make sure the washer (1) is installed before attaching the spray head to the hose.
Pull the hose assembly out of the spout and remove the spray head (A) by unscrewing it from the hose in a counterclockwise direction. Be sure to hold the end of the hose down into the sink and turn the faucet on to the warm position where it mixes hot and cold water. Flush the water lines for one minute. This flushes away any debris that could cause damage to internal parts. Check for leaks. Retighten any connections if necessary, but do not overtighten. Reinstall the spray head (A) by hand tightening it back onto the sprayer hose. After installation is completed, turn on the hot and cold water supplies. Check for leaks.
