Installation and Service Instructions

Installation

Caution: Be sure to turn off hot and cold water supplies
before installing or servicing faucet.

1. Loosely install the anchor bar (KN-23), spacer (KN-26) and

nut (L-36) on the mounting bolts and place gasket on base
of faucet. Push faucet supplies and anchor bolt/spacer/nut
assemblies with gasket through holes in sink. Secure faucet
to sink by tightening nuts from underside. (If sink or coun­ter surface is uneven, use putty or sealant to make proper
seal under base.)

2. Connect hot supply to le tube and cold supply to right
tube using appropriate connectors.

3. Pop-up drain installation:
a) Remove pop-up plug, tail piece and ange from the drain

body. Make sure that locknut is threaded all the way
down onto the body with at friction washer in middle

and beveled washer on top.
b) Apply plumbers putty or sealant to bottom of ange.
c) Install drain body through drain opening in lavatory

and screw ange onto the drain body making sure that

the threads are completely engaged for proper sealing

and strength of the connection. Apply joint compound

to all threaded parts to insure proper seal. Apply putty or

teon tape to tail piece before attaching to drain body.
d) Tighten locknut to compress the beveled ange evenly

across the bottom of the drain opening taking care not to

over tighten the locknut, causing damage to the lavatory.
e) Remove one of two ball washers from inside the

threaded cavity. Insert pop-up plug and pivot rod into

body. Add one ball washer (the second ball washer

should remain inside the body) to the outside of the ball.

Tighten the retaining nut until the ball is seated on the

internal and external ball washers.
Note: e pop-up plug can be installed either in the remov-

able or non-removable position, depending on the location

of the hole located in the guide at the bottom of the plug.
f) Slide the pivot rod through one side of the spring clip,

then the appropriate adjustment hole and then other

side of the spring clip.
g) Insert li rod through faucet housing and the top of the

li strap and secure it in place by tightening the screw.
Note: To ensure proper operation of li rod and pop-

up, some adjustment of the linkage may be required.

ere are two possible adjustment points: 1) li strap to

li rod and 2) li strap to pivot rod.

4. It is very important to thoroughly ush the supply lines to
prevent foreign matter, i.e. copper chips, sand, stones, etc.
from damaging the sealing surfaces of cartridge.

Remove aerator and turn valve handle on to full cold posi-

tion, open cold supply. Without closing, turn handle to full
hot and open hot supply. Let water run in hot only and cold
only positions long enough to ush supply lines thoroughly.
Shut o faucet and replace aerator. Check for leaks.

5. e handle limit stop can be
set to limit handle turn to
the hot position. e limit
mechanism is factory set to
allow full handle travel. To
adjust the limit stop, turn
handle to the full hot position
and li handle to open faucet
approximately half way to
obtain a smooth ow for
correct initial temperature
measurement.

6. If when faucet is on and in
full hot position and water is
too hot, remove plug button
(KN-157), loosen set screw (L-

22) and remove handle (KN-3RB, KN-3BRB or LN-135).
Li limit stop ring (KN-4L) using a small at head screw
driver and rotate counter clockwise to lower temperature.
If water is not hot enough, rotate clockwise (See Figure
1 on reverse side). Aer correct temperature is achieved,
reattach handle, reversing procedure above.

Replacing cartridge (KN-4)

1. Remove plug button (KN-157), loosen set screw (L-22) and
remove handle (KN-3RB, KN-3BRB or LN-135).

2. Engage tabs in cartridge wrench (LN-34) with slots in com­pression ring (KN-2) and use screwdriver in wrench holes or
pliers on wrench and turn counter clockwise until compres­sion ring engages with cap (LN-8). Continue turning counter
clockwise so that cap/ring assembly is removed from the body
(LN-371). Remove cartridge and three ring seal (KN-4).

3. Install new cartridge while taking care to maintain position
of the three ring seal at the base of the cartridge. Match
posts in base of cartridge with alignment holes in valve
body during assembly.

4. Reassemble faucet in reverse fashion. read cap onto body
rmly by hand. Do not use a wrench which may damage
the nish. Tighten compression ring (KN-2) nger tight
using the wrench (LN-34) then 1/4 to 1/2 turn further.

5. Set hot water limit stop in accordance with installation step
5 above.
