remove it and the  stem extension.  Grasp the cartridge stem with pliers and pull it STRAIGHT out of the housing.

FOR HUB MODEL 62977:  Pry off knob insert.  Remove handle screw and pull off know handle.  Remove hub (if it is cover-
ing the wrench flats on the cartridge nut) and loosen the cartridge nut with an adjustable wrench and remove it and the

Disassembly

CAUTION:

Failure to follow these instructions might cause the cartridge to be damaged beyond repair.

Before installing cartridge, turn the stem to the ON position, waterway holes in the cartridge are lined up.

FOR WALL TUBE MODELS:   Insert the cartridge STRAIGHT into the housing making sure that the lug on the cartridge is
engaged in the notch in the valve body.  Place the stem extension over the cartridge stem and replace the cartridge nut,
START BY HAND, DO NOT CROSS THREAD, tighten the nut firmly with an adjustable wrench.  Push on the wall tube, replace
escutcheon retainer and escutcheon.  Replace handle parts.

FOR HUB MODEL 62977:  Assemble the handle knob to the new cartridge using the handle adapters and tighten the handle
screw.  This will aid in locating the cartridge properly in the valve body.  Place the cartridge into the valve body and push
inward.  Now push firmly while rotating handle knob counterclockwise.  This will align the KEY on the cartridge with the
NOTCH in the valve body.  When the key enters the notch, you will feel it drop in and the cartridge will be in place.  To be cer-
tain, rotate the handle clockwise and then counterclockwise with gentle force.  You should feel the handle knob stop in both
directions.  If so, the cartridge is in place.  Do not turn water on yet.  Unscrew handle screw and remove handle knob in order
to replace the cartridge nut.  Replace o-ring and nut, START BY HAND, DO NOT CROSS THREAD.  Tighten the nut firmly with

This valve is designed for either CC or IPS connections, depending on the discretion of the installer.  If
using the IPS connections, thread sealing tape should be used liberally on all threads.

Connect the valve to the supply lines by either means desired.  The hot supply should be on the left, the
cold supply on the right.

Connect the shower riser pipe to the top outlet and the tub drop pipe to the bottom outlet.  Make all
connections firm and tight.  Block and secure all pipes to the inside wall.

Installation

MAKE SURE ALL WATER SUPPLIES ARE OFF

SHOWER:  Assemble shower arm flange to the long end of shower arm.  Put thread seal tape on the threads at both
ends of the shower arm.  Screw shower arm into ell inside wall, do not install showerhead at this time.  When a pipe
lookout nipple is used, put thread seal tape on the pipe thread and screw the tub diverter spout into the lookout
nipple.  

* CAUTION:  spout is ABS plastic and will crack upon contact with some pipe thread compounds.  We

recommend the use of thread seal tape.

Pull out while turning so as not to scratch the wall.  If a final turn by a

wrench is needed, use a small one with smooth jaws to grip spout end.  Do NOT insert a tool into the spout end to
turn.  You could damage the spout.

Trim

For water supply lines plummed ceiling to floor, please follow these instructions:

Hold the valve with the valve connections in the down position as illustrated below.  Use a large flat blade screwdriver and
remove the flow director, located in the center port, as illustrated.  After removing the flow director, turn the valve over so
that the valve connections are in the up position, and reinstall the flow director.

Now the casting can be turned over, with the valve connections facing the ceiling, to accept ceiling-to-valve water supplies.

IMPORTANT:

Pipe chips, sand, stones, and other solids found in new and renovated plumbing can damage the sealing
surface of the cartridge and cause a leak.

1.  After installing and connecting your new faucet, install shower arm and tub spout, open both hot and cold cartridges.
