Install HOT on left and COLD on right
according to valve markings.
1. Install piping and ttings with valve
body as shown in Figure 2 or 3.
IMPORTANT: Valve rough-in is 23/8”
(60mm) min. — 3” (76mm) max.
from CENTERLINE OF SUPPLIES
TO FACE OF FINISH WALL. Install
so that surface indicated on plaster
shield on valve is ush with nish
wall as shown in Figure 1.

2. When nishing tile wall REMOVE
(pull off; don’t turn) ENTIRE PROTECTIVE PLASTER SHIELD and
FILL AREA AROUND VALVE BODY
WITH GROUT OR PLASTER. DO
NOT PLASTER OVER SC-2 CAP OR
SERVICE STOPS IF SO EQUIPPED.
3. Turn on hot and cold supplies, valve
will not operate unless both hot and
cold water are turned on.
4. This valve is equipped with a limit
stop screw to be used to limit
valve handle from being turned to
excessively hot water discharge
temperatures. To adjust, remove
dome cover, place handle (VT-112)
on stem, open valve to maximum
desired temperature and turn
in limit stop screw until it seats.
WARNING: Failure to adjust the limit
stop screw properly may result in
serious scalding.

WARNING: This shower system may
not protect the user from scalding when there is a failure of other
temperature controlling devices
elsewhere in the plumbing system.
5. Check packing nut (SC-7) for positive frictional resistance to handle
turn throughout adjustment cycle
and at shut-off position, tighten if
neccessary. Check valve cap, packing nut and all valve, pipe and tting
connections for leaks. Reattach
dome cover back onto packing nut.
6. After nish wall is completed,
remove protective backing from
escutcheon gasket (T-149) exposing
adhesive and adhere to inside top
diameter of escutcheon (SC-144).
This step should not preclude sealing valve body in wall as directed in
installation instruction step #2.
7. Push escutcheon and gasket
against wall and secure to valve
with escutcheon screws (WO-20A).
Mount temperature control handle
(VT-112) on valve spindle spline,
secure with screw (SC-15A). Install
shower arm, ange and shower
head. See Figures 2 and 3. Install
tub spout on diverter twin-ell stub
out (1-215-X only). Use putty or sealant on back edge of spout to make
proper seal with nished wall.
8. ALLOW VALVE TO RUN IN WARM
POSITION FOR A FEW MINUTES
TO TOTALLY FLUSH SYSTEM.
IF SYSTEM IS QUITE DIRTY,
REMOVE VALVE SPINDLE OR STOP
SPINDLES (IF SO EQUIPPED) TO
INSURE PROPER FLUSHING. See
service instructions.
9. Do not install positive shut-off
devices on the outlet of this valve or
devices that do not allow the valve
to ow at least 1 GPM at 50 psi inlet
pressure. EXCEPTION: If a self-closing or slow-closing valve is installed
on the outlet, the supplies of the
valve must be equipped with checks
to eliminate hot to cold by-pass in
the event the valve’s handle is not
turned to off after use. Contact your
factory representative or Symmons
directly for information on available
checks.

FIBERGLASS WALL
INSTALLATION
When installing Safetymix in berglass or panel walls and it is desired to
sandwich wall between valve body and
escutcheon, cut hole in wall as shown
in Figure 4 and mount valve from rear.
Note: It is always recommended to
secure valve piping to rough construction and not depend on berglass wall
for valve mounting security. On panel
walls over 1” thick, install in conventional manner. (See gure 1).
SC-130
SC-126 TO BE DISCARDED BEFORE INST ALLING TRIM
OPERATION OF VALVE
The main handle of the Safetymix valve
is for control of temperature only. From
the OFF position, the handle is turned
counter-clockwise through a minimum
cold position, through a warm and hot
position for a maximum turn of approximately one revolution. This allows for
innite temperature adjustments to suit
the requirements of any user.
CARE AND CLEANING
The lustrous nish on your Safetymix
valve should be treated with care. It
can be readily damaged by improper
handling or abusive treatment. To clean
the nish wipe gently with a soft damp
cloth and blot dry with a soft towel. Use
only a mild soap solution if required. DO
NOT USE ABRASIVE CLEANERS. USE
OF POLISH, ABRASIVE CLEANERS,
SOLVENTS OR ACID CLEANERS WILL
DAMAGE THE FINISH AND VOID THE
SYMMONS WARRANTY.

SERVICE
1. Shut off water supply to valve.
2. Loosen set screw (SC-15A) and
remove handle (VT-112), dome cover
(SC-13), and escutcheon (SC-144) in
that order.
3. Open valve to about warm position
and unscrew cap (SC-2). Warning:
Failure to OPEN VALVE will damage
cap and spindle. Spindle assembly
(C-5) will be removed with cap. Leave
packing nut (SC-7) in place while
unscrewing cap to avoid distortion.
4. Ordinary service to eliminate dripping or not shutting off requires only
the replacement of parts supplied in
washer and gasket kit (KIT-B). Hold
spindle with (VT-112) handle while
removing hot washer screw and cold
washer retainer (remove retainer with
channel
lock pliers).
5. Inspect surfaces of renewable seat
(SC-3). If seat surfaces are worn or
wire drawn or if NEW SPINDLE IS
VERY LOOSE IN SEAT, replace SC-3
renewable seat. Use renewable seat
socket wrench (C-50). Clean seat
surfaces for proper sealing of top
seat o-ring (SC-20A) and bottom seat
gasket (SC-21). Tighten seat to 15
foot pounds of torque.
6. The perforated end of the (C-5)
spindle assembly houses the
balancing piston which is the heart
of this pressure-balancing valve. The
piston should be free to move back
and forth and should click when
the spindle assembly is shaken. If
deposits block this action, tap the
handle end of the spindle against
a solid object to free the piston.
Soaking in household vinegar will
help free foreign matter. If this does
not free piston, replace (C-5) spindle
assembly.

procedure. Be sure spindle assembly
is drawn close to the cap before
screwing cap back into valve.
Warning: Failure to do this will
damage cap and spindle.
