Extended Product Information
FAQs
Can I use this in an oil-based medium?
This unit is designed primarily for liquid heating applications; please verify the fluid compatibility with Incoloy 800 before installation.
Is the thermostat accurate?
The thermostat is a standard industrial control component designed for process regulation within a 30–85°C range.
Does this require a neutral wire?
Yes, it is designed for a 230V single-phase supply which requires phase, neutral, and earth connections.
What happens if the element is not fully submerged?
Operating the heater without full immersion will cause overheating, likely leading to the failure of the heating element.
Can the cable be extended?
It is recommended to use an appropriately rated junction box and cable if an extension is necessary, handled by a qualified electrician.
What is the IP45 rating?
IP45 indicates protection against solid objects over 1mm and low-pressure water jets from any angle.
Troubleshooting
Heater fails to activate
Check the power supply and ensure the thermostat is set to a temperature higher than the current liquid temperature.
Pilot light is on but liquid is not heating
Verify the element has not been dry-fired; check continuity across the element terminals with a multimeter after disconnecting power.
Thermostat does not reach desired temperature
Ensure the thermostat probe is correctly positioned and not obstructed; verify the supply voltage is consistently at 230V.

Setup, Compatibility & Care
Installation requires a G1½" threaded boss. Ensure the unit is installed vertically or horizontally depending on the specific tank design, provided the element remains fully submerged. For long-term performance, periodically inspect the Incoloy 800 elements for scale buildup, especially in hard water environments. Always disconnect power before opening the IP45 terminal box for inspections or adjustments. Ensure the M20 cable gland is tightened to maintain the IP45 seal, preventing moisture ingress that could compromise internal connections.
