00 · Scope

What this manual covers

This manual is written for homeowners, installers, technicians and distributors who run SunAura heating products. It is organised by product family because products in a family share the same installation, maintenance and fault patterns — even when sizes and ratings differ.

  • A
    Overview — what the product is and what it is designed for.
  • B
    Key specifications — rated power, voltage, dimensions, IP rating and certifications.
  • C
    Routine maintenance — an actionable checklist for reliable long-term operation.
  • D
    Troubleshooting — common fault symptoms with likely causes and remedies.
  • E
    Support — verified contact channels for technical and after-sales assistance.
01 · How to use

How to use this manual

  1. Identify your product. Read the model and rating from the product label.
  2. Find the family chapter using the table of contents in the PDF, then confirm your exact model appears in that chapter.
  3. Check the rating first. Verify supply voltage and connection against the label before any work.
  4. For a fault, go to troubleshooting. Match the symptom and work the causes top-to-bottom.
  5. When in doubt, contact support — never operate a heater that behaves abnormally.
02 · Safety & electrical

General safety & electrical warnings

  • Disconnect the power supply before installation, inspection, cleaning or maintenance of any heating product.
  • Verify that the supply voltage matches the product rating before connection. Operating outside the rated voltage range can cause damage or a fire risk.
  • Respect the waterproof (IP) rating: use only rated models in the intended environment and keep all electrical connections dry and inside approved junction boxes.
  • PTC self-regulating cables limit their own temperature — do not cover them beyond the design limit and never operate them coiled or overlapping.
  • Do not cut or shorten film busbars or heating cables unless the product is explicitly designed for field cutting.
  • Do not overlap heating film or cable on itself; overlapping can cause local overheating.
  • Install in accordance with national electrical codes; use an RCD/GFCI-protected circuit for wet-area applications.
  • If a product fails to heat or behaves abnormally, switch it off and have a qualified electrician inspect it before reuse.
03 · Routine maintenance

Keep it running

Most heating faults trace back to a skipped check. Work through the interval that matches how the system is used.

Before each use Check the surface is clear of debris, sharp objects and heavy furniture. User
Monthly Inspect the thermostat, junction box and visible cable for damage or moisture. User / Installer
Annually Verify the RCD / GFCI and protection respond correctly; test sensor accuracy. Qualified electrician
Annually Check film / mat connections are tight and dry; confirm insulation resistance. Qualified electrician

    Can you help with wiring for a heating system I already installed?

    Yes — send photos of the thermostat backplate and junction box, tell us the load, and our engineers will confirm the correct wiring and settings by WhatsApp or email.

    Do you offer a warranty for bulk / OEM orders?

    Yes, the same factory warranty applies to wholesale and OEM orders. We record batch numbers at production so every unit is traceable for its full warranty period.

    How do I get a replacement under warranty?

    Use the form above, choose Warranty claim as the request type, and attach photos of the fault plus your order number. We will diagnose and, if confirmed, dispatch a replacement from the factory.
