5. Installation
Proper installation is crucial for the accurate and safe operation of the thermostat. If you are unsure about any step, consult a qualified technician.
- Stromabschaltung: Ensure the hot water pressure washer is completely powered off and disconnected from its power source before beginning installation.
- Montage des Thermostats:
- Select a suitable panel location for the thermostat unit. The location should be easily accessible for temperature adjustment and protected from excessive moisture or vibration.
- Cut an appropriate opening in the panel for the thermostat body.
- Secure the thermostat unit to the panel using the provided mounting hardware.
- Attach the control knob to the thermostat shaft.
- Capillary Tube and Bulb Installation:
- The copper sensing bulb must be inserted into the hot water stream or a thermowell within the pressure washer system where accurate temperature measurement is required.
- Use the provided brass fitting to secure the sensing bulb in place, ensuring a watertight seal.
- Route the 60-inch capillary tube carefully, avoiding sharp bends, kinks, or contact with hot surfaces that could damage the tube or affect its accuracy. The tube should be protected from physical damage.
- Ensure the capillary tube is not under tension.
- Elektroverkabelung:
- Connect the thermostat's electrical terminals to the pressure washer's heating element control circuit. Refer to your pressure washer's wiring diagram for specific connection points.
- The thermostat is rated for 16(4)A-380V. Ensure your system's electrical load and voltagWir sind kompatibel.
- Sämtliche Verkabelungen müssen den örtlichen Elektrovorschriften und -normen entsprechen.
