Potential scald or thermal shock injury could result due to cross ow if outlet at the shower is
blocked or restricted (e.g., pause control on hand shower). Be sure to point hand shower away
from you when re-starting ow or install inlet check valves on both supply lines to prevent
possible injury.
Maintenance
Cannot receive more than a trickle of water:
Both hot and cold supply lines must be pressurized.
If only one side is pressurized, the system will not
allow adequate ow of water.
Faucet leaks from shower outlet: Remove the
hand shower then turn the water on and o󰀨 to verify
if the cartridge is leaking or the hand shower is
draining slowly (the hand shower may need to be
cleaned if water drains slowly).
If leak persists -SHUT OFF WATER SUPPLIES
Replace cartridge assembly - RP47201.
Unable to set or maintain mixed water temperature:
SHUT OFF WATER SUPPLIES. Remove handle
assembly, trim sleeve, and bonnet nut. Check to make
sure the “H” marking on the cartridge aligns with the
hot inlet and the “C” marking on the cartridge aligns
with the cold inlet to the valve body. The thermostatic
cartridge cannot function if hot and cold inlets are
reversed.
Low ow:
Low ow may be caused by clogged screens within
the thermostatic cartridge. To clean the hot and cold
screens in the cartridge, follow the steps below:
1. SHUT OFF WATER SUPPLIES.
2. Remove the handle assembly.
3. Unscrew the hex shaped portion of the cartridge
from the brass section of the cartridge. The brass
section must be held securely by the ats while
the hex is rotated counter-clockwise. Failure to
secure the brass section while rotating the
hex can result in damage to the cartridge.
(See illustration below)
4. Carefully clean any debris from the screens
under running water. If the debris is di󰀩cult to
remove then soak the screens overnight in a
50% water and 50% vinegar solution.
5. Reassemble the cartridge.
6. Replace the handle.
7 Turn the water back on.
8. Reset the limit stop before using the valve.
