Leonard Type XL Thermostatic Water Mixing Valves are
simple in design and may be easily cleaned, adjusted and
repaired. If the installation is accessible, servicing may be
completed without disconnecting the valve.
NOTE: Thermostatic Water Mixing Valves are
REGULATING mechanisms, which must be regularly
maintained to provide best performance. Frequency of
cleaning depends on quality of local water conditions and
usage. (See Maintenance Guide and Record MGR-1000).
TROUBLESHOOTING INSTRUCTIONS
SERVICE
WARNING
WARNING! This Thermostatic Mixing Valve has an Locking
Temperature Regulator (LTR) which must be checked. If the temperature
is too high, the installer MUST RESET this adjustment immediately.
Always check the temperature of the mixed water after installation.
Excessively hot water is DANGEROUS AND MAY CAUSE
SCALDING!
The LTR is factory set at approximately 120°F (49°C) with an
incoming
hot water supply temperature of 150°F (65°C) If the incoming hot water
supply for your installation is higher than 150°F (65°C), the valve may
deliver water in excess of 120°F (49)° and the LTR MUST BE RESET
BY THE INSALLER.
