Note 1) Initial power and power consumption are nominal values.
Note 2) Heaters are not available for size 16.
Note 3) For mounting, refer to the Specific Product Precautions 2 on page 5. For installation, refer to
"Precautions for use 2" on page 6 and "Parts replacement procedure" on page 19.
Note 4) As the stable temperature of the heated product may vary by approx. ±10 to 15% due to instrumental
error, be aware that the temperature specifications are to be used as a guide only (H4: 100°C and H5:
120°C)
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
o
200 C, then it may fail. The maximum operating
temperature for the valve is 150
temperature is over 200
o
over 150 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.
