Key specifications
 Power: 1.4 kW
 Thread type and size: 5/4" TSE threaded connection
 Mounting: Immersion (in-line) heater suitable for direct installation into tanks or boilers
 Intended medium: Water and compatible liquids
 Application: Domestic and light industrial heating
How to use
Before installation, ensure the tank or boiler is drained and isolated from power. Verify that the 5/4" TSE thread on the vessel matches the heater connection and that the immersion depth is appropriate for effective heat transfer. Fit the heating element into the threaded port and secure it to the recommended torque for the fitting material, using appropriate sealing where required. Refill the tank, restore electrical supply through a correctly rated circuit and protection device, and monitor the first heating cycle to confirm normal operation and absence of leaks.
Usage recommendations
Use a thermostat or temperature controller compatible with 1.4 kW load and install overcurrent protection and residual current device (RCD) according to local wiring regulations. Avoid energizing the heater when not fully immersed to prevent overheating. For safe long-term operation, periodically inspect the element and connections for corrosion or scale buildup and follow manufacturer guidance for maintenance.
