PREVENTATIVE MAINTENANCE
EVERY 6 MONTHS
1 Check and adjust the temperature setting
EVERY 12 MONTHS
1 Shut off the water supply
2 Open up checkstops
3 Clean strainers and check for free movement of checkstop poppet
4 Replace seals if cracked, cut, or worn
5 Re-assemble
6 Adjust stem to the desired temperature
TROUBLESHOOTING
1 If the flow of water is less than desired
• Valves upstream from supply not fully open
• Low supply pressures
• Accumulation of lime deposit is in hot water pipes, restricting the flow of water
• Checkstops not fully open
• Clogged strainer screens in the checkstops
• Clogged cartridge
2 Flow of water is completely cut off
• Valves upstream from supply completely closed
• Failure of cold water supply pressure (mixing value is designed to shut off on a cold water supply failure)
• Checkstops completely closed
3 Flow low is untempered hot or cold water
• Valves Accumulation of time deposits in hot water pipes, restricting the flow of hot water
• Thermostatic actuator failure; replace with new thermostatic actuator
• Hot and cold water supplies are connected to the wrong ports
4 Maximum temperature specified for the mixing valve cannot be obtained
• Accumulation of lime deposits in hot water pipes restricting the flow of hot water
• Hot water supply temperature is too low
5 Variable discharge temperature occurs
• Extreme pressure variations in supply lines
• Valve operating below minimum capacity requirements
