Installation

B
EFORE YOU BEGIN
On tiled wall surfaces, grouting must be either flush or raised for proper sealing of the cover plate.
IMPORTANT: It is not necessary to remove the cartridge from the valve during NORMAL soldering operations using
propane-butane gas. DO NOT USE OXYGEN-ACETYLENE. When soldering connections, do not solder within
4” of valve port. Do not use excessive heat. Open the stop valves when soldering inlets.
It is recommended that the pipes be flushed clean prior to installation, in order to avoid any future problems.
Ensure that the stop ring is properly installed, see below, otherwise a user could potentially disengage the cartridge
with minimal force to external handle. This would cause the valve to fail, losing control of flow & temperature.
Make sure valve is securely fastened to studs. Be sure to remove trim items, handles, escutcheons and plates before
installation. Wrap carefully and store until finished wall is completed.
Install the valve by positioning the 1/2” shower outlet in the up position. If installing showerhead & hand shower config-
uration, plumb showerhead from tub port (T) and hand shower from shower port (S). Finished wall must be within
dimensions shown in illustration 2. To test pipe joints, pressurize both hot and cold inlets.
Installing Trim
Thread plastic upper link into finished post. Insert assembled post onto end of diverter stem, then slide finished sleeve
over attached items and screw sleeve into diverter housing. Place coverplate on valve stem while sliding diverter trim
through rubber grommet. Screw on escutcheon trim and mark all-thread nipple where excess needs to be cut off.
(NOTE: For stem to be fully seated into cartridge, all-thread nipple and locking nut must be tightly secured against
retaining plate.) Place handle on stem. Measure excess between escutcheon and handle base. Remove handle and cut
previously measured excess from end of stem. Secure handle into place by tightening the handle setscrew or tightening
the bonnet depending on handle construction.Screw diverter knob onto finished post. (Refer to Illustrations 2 and 3.)
