California Faucets Thermostatic Cartridge - Manual (Page 4)

Carefully open both the hot and cold service
stops on the valve body using a small number one
(electrician type screwdriver). Do not rotate the
slotted head of the service stop screw beyond the
flat face of the hexagonal service stop housing.
Remove the shower arm and apply new Teflon
tape or thread sealant to all threads to ensure a
watertight connection to prevent a leak behind
the wall. Apply Silicone sealant or equivalent to
backside of shower arm and secure shower arm
to wall. Shower arm outlet should be downward.
Refer to installation instructions for Thermostatic
valve TH‐150 / TH‐175 for temperature
calibration and trim installation.
Here are examples of calcium build up, debris and
sediment that can cause a cartridge to become
stuck in a thermostatic valve body.
If hard water is present, the cartridge should be
removed and serviced every 1 or 2 years.
Annual service of the cartridge is as follows:
Soak cartridge in 100% undiluted white vinegar
for 2‐6 hours or until all calcium build up is
dissolved. Use old toothbrush to remove
deposits or debris on stainless steel screens.
Avoid excessive pressure on screens as this may
cause damage.
