INSTALLATION INSTRUCTIONS Pressure Balancing Valve Valve

INSTALLATION INSTRUCTIONS Pressure Balancing Valve Valve
Pressure Balancing Valve
Valve Body No. 1-685
as used with Tub and Shower Fittings
This valve is precision engineered to provide satisfactory performance provided it is installed and operated in
accordance with our recommendations contained in these instructions. In order to fully enjoy the comfort,
safety and the reliability of this valve, be certain to familiarize yourself with these instructions.
The pressure balancing cartridge contained in this valve
compensates for pressure fluctuations in the water supply system through a spool and sleeve pressure balancing
mechanism. The outlet temperature will change by no
more than a mere ±2°F (1°C) with a 50% drop in either
the hot or cold water pressure. Even if the cold water
pressure fails completely, the anti-scald design will reduce
the flow rate to a safe level ensuring reliable protection
against scalding. The built-in check valves prevent cross
flow between the hot and cold supplies.

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 configuration, 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.)

Setting the Temperature Limit Stop
This valve has an upper temperature limit stop , which can allow desired and safe hot water temperature
(recommended maximum is 110°F). This stop may be adjusted once the valve is installed.
Before making this adjustment, run water with the valve turned to the hot setting. If the water temperature
is too high in this position, then perform the following adjustments:
1. Remove the trim (handle, escutcheon and cover).
2. Remove the all-thread nipple, (item 7), hex nut (item 8) and stem plate (item 6).
3. Remove the broach stem (item 5) and the limit stop (item 4).
4. Close the valve by turning the cartridge stem clockwise until it stops, (Illustration 4).
5. From the CLOSED position, rotate the cartridge stem counter-clockwise until the desired temperature is
achieved.(Illustration 5).
6. Place the limit stop (item 4) on the cartridge stem against the stop block (Illustration 6). Rotate several
times to make sure the stop is at the desired temperature setting.
7. Install the broach stem (item 5), stem plate (item 6), all thread nipple (item 7) and hex nut
(item8).(NOTE : For broach stem to be fully seated onto cartridge, the all thread nipple (item 7) and hex
nut (item 8) must be tightly secured against the retaining plate).
