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 (SC-2), packing nut
and all valve, pipe and fitting connec-
tions for leaks. Reattach dome cover
back onto packing nut.
6. Be sure that Step 2 has been com-
pleted properly and finish wall is
in place before proceeding. Slide
escutcheon assembly (VT-105) over
dome cover (SC-13/18) already on
valve body. Carefully align thermometer
probe with hole in valve body and
gently push escutcheon against wall.
Secure escutcheon to valve body with
two escutcheon screws (WO-20A).
Mount control handle (VT-112) on valve
stem. Check handle alignment. Tighten
handle screw (SC-15A) to mesh slot
in valve stem. Snap On/Off indicator
(VT-104) into slot in escutcheon con-
cealing escutcheon screws.
7. Install shower arm, flange and shower
head. See figures 2 and 3. Install tub
spout (1-2100VT only). Use putty
or sealant on back edge of spout to
make proper seal with finish 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 flow 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.
