Note 1) Initial power and power consumption are nominal values.
Note 2) Heaters are not available for the size 16 models.
The heaters are PTC thermistor type design.
These thermistors self regulate their temperature
by switching the resistance at certain critical
temperatures, so a separate temperature
controller is unnecessary.
If the temperature of the PTC heaters fitted exceeds
200
o
C, then it may fail. The maximum operating
temperature for the valve is 150
o
C. If the heater
temperature is over 200
o
C or valve temperature is
over 150
o
C, please use thermostat to control the
heaters to prevent overheating.
With PTC type heaters, there is an initial surge of current (inrush current) after the power is supplied.
These inrush current will reduce overtime. If multiple heater assemblies are used, the inrush current to
the heaters will be magnified and care should be taken. When multiple heater assemblies or valves
are used, do not apply power to the heater assemblies simultaneously. Keep approximately 30
seconds between applications of power to each heater assembly. This will allow for incremental
spacing to prevent harmful large initial surge.
