The Mialuz MZTS030 is a professional-grade solar thermal system collector designed for residential and commercial hot water applications. It features high-efficiency evacuated tubes, a durable aluminum frame, integrated mounting hardware, frost protection, and compatibility with standard solar water heating systems. Proper installation is crucial for optimal performance and safety. Below are key sections covering safety, components, installation steps, system integration, commissioning, and maintenance.
Installation must be performed by qualified personnel in accordance with local codes and regulations.
| Hazard | Precaution |
|---|---|
| Falling objects/collector | Use proper lifting equipment and secure the collector during assembly. |
| Electrical shock | Disconnect all power sources before making electrical connections. |
| Hot surfaces & fluids | Allow system to cool before servicing; wear protective gloves. |
| Roof/work at height | Use fall arrest systems, secure ladders, and ensure stable footing. |
| Pressure & leakage | Pressure test system before final operation; check all joints. |
Unpack carefully and verify all parts against the packing list.
WARNING! Do not discard packaging until all components are verified. Report any damage or missing parts immediately.
Proper site assessment ensures optimal solar gain and system efficiency.
CAUTION! Never install under trees, near chimneys, or where debris may accumulate.
Use only recommended pipes and fittings. All connections must be leak-free.
Tools Required: Pipe cutter, deburring tool, adjustable wrenches, torque wrench, pressure gauge.
Hydraulic Schematic: Collector -> Insulated pipes -> Pump station -> Heat exchanger -> Storage tank -> Return line. Ensure expansion vessel is installed on the closed loop side. Fill system with recommended heat transfer fluid (propylene glycol mix). Bleed air from all high points using manual air vents.
For systems with differential temperature controller and circulation pump.
Tip: Use conduit for outdoor cable runs and seal entry points against moisture.
Follow this sequence to start up the system safely.
WARNING! Do not expose empty collector to direct sunlight. Always fill with fluid before sun exposure.
Default controller settings are optimized for most installations. Monitor system for first few days.
Regular maintenance ensures long-term performance and efficiency.
Monthly: Check for fluid leaks, unusual noises, and controller readings.
Annually: Inspect tube condition (clean if dirty), check fluid pH and freeze protection level, tighten mounting hardware, verify insulation integrity.
CAUTION! Never use abrasive cleaners on glass tubes. Use soft cloth and mild detergent only.
| Symptom | Possible Cause | Corrective Action |
|---|---|---|
| No hot water | Pump not running | Check power to pump; verify controller settings and sensor connections. |
| Low system pressure | Fluid leak or air in system | Pressurize system; inspect for leaks; bleed air from high points. |
| Reduced efficiency | Dirty tubes or scaling | Clean tubes with soft cloth and water; descale heat exchanger if needed. |
| Unusual noise from pump | Air lock or bearing wear | Bleed air; if noise persists, replace pump. |
| Fluid discoloration | Degraded glycol or corrosion | Test fluid chemistry; flush and replace fluid if necessary. |
Reset: Power cycle controller to reset electronic faults.
Service: Contact authorized technician for complex issues. Refer to warranty terms.
