Installation
Sizing Valve
For assistance in sizing and selection of the proper
valve, consult your local representative or Symmons
Customer Service.
Installing Valve
1) Flush piping thoroughly prior to installing.
2) Install valve so as to allow clearance for replacing
cartridge. Valve can be installed in any orientation.

3) Connect valve input/ouput to supply ports.
a. Hot port marked (H)
b. Cold port marked (C)
c. Mixed output port marked (M)
Setting Valve Temperature
1) Turn hot and cold water supply on.
2) Open faucet to allow hot water to ow for a
minimum of one minute. For two handle faucets
turn on hot water only. For single handle faucets
turn on to the hot position.
3) Remove screw and cap.
4) Place thermometer in the outlet stream. Measure
and accurately set temperature. Inlet temperature
must be ± 10°F (5.55°C) of desired output.
5) To increase temperature turn stem counter-clock-
wise. To decrease temperature turn stem clock-
wise.
For single temperature applications adjust valve
outlet temperature with full ow of tempered
water from tting.
For dual temperature applications open
approximately 50% of all faucets to their full hot
position to ensure proper operating temperature
at peak demand.
6) Replace cap and screw once desired tempurature
has been met
Note: Once the safety cap and screw have been
installed the outlet temperature cannot be changed
without repeating steps 2-6.
Warning: Water temperatures in excess of
110°F (43°C) may cause scalding, or
severe injury!

Operation & Maintenance
Initial 30 Day Inspection
Inspect cartridge within 30 days of initial operation.
If inspection determines that your water system is
causing deposits and foreign matter to build-up,
then adjust cartridge maintenance accordingly.
Cartridge Replacement
1) Shut off hot and cold water supplies to valve.
2) Remove screw and cap. This will expose the
cartridge stem and cartridge retaining nut.
3) Remove retaining nut by turning counter-clockwise
with adjustable wrench. Grasp cartridge with
pliers and remove from body by pulling straight
out. A slight rocking rotation may be required to
loosen while removing.
4) Lubricate cartridge o-rings with a small amount of
silicone lubricant prior to reinstalling. Insert replace
ment cartridge into valve body, applying enough
force to ensure cartridge is fully seated. Install
retaining nut back onto valve body.
5) Refer to “Setting Valve Temperature” section (pg.3)
to properly set valve to desired temperature.
Seasonal Use
If valve is used seasonally, such as in schools or
campgrounds, then perform the following steps to
avoid damage caused by freezing water when valves
are not in use:
1) Shut off hot and cold water supplies.
2) Remove valve cartridge and drain all water.
3) Drain water from the supply lines and valve body.
Service Instructions
Cleaning screens & check valves:
1) Shut off hot and cold water supplies.
2) To clean screens leave cap installed. Remove
retaining nut and remove cartridge. Clean debris
from screens and body. Apply silicone lubricant to
O-rings and reinstall.
3) To Replace the check valves, remove the supply
lines and remove check valves from center body.
Reinstall new check valves. Reconnect supply
lines.

Care and Cleaning
Trouble Shooting Chart
Problem Cause Solution
Water ow is less than normal. Screen in cartridge is dirty or
clogged.
1) Remove cartridge and clean un-
der running water.
2) Remove cartridge and clean in
household vinegar or replace by
ordering cartridge replacement kit.
Water continues to run colder than
original temperature setting.
Check valve is not completely
sealed allowing cold water to mix
with hot.
Remove screen/check valve and
clean under running water.
Valve is leaking around the cap
retaining nut area. Water leaking from o-ring seal. Replace cartridge by ordering cartridge replacement kit.
Tempered hot water temperature is
not hot enough.
Hot water supply into valve is not
10°F (5.55°C) above desired set
point temperature. Temperature
setting it to low.
Increase hot water supply
temperature into valve. Reset
temperature according to "Setting
valve temperature" instructions.
Remove cartridge and clean valve body in household vinegar to remove corrosive mineral build up. Rinse
under running hot water to ensure valve is free of foreign debris.
