Safety Precautions

Installation must be performed by qualified personnel in accordance with local codes and regulations.

HazardPrecaution
Falling objects/collectorUse proper lifting equipment and secure the collector during assembly.
Electrical shockDisconnect all power sources before making electrical connections.
Hot surfaces & fluidsAllow system to cool before servicing; wear protective gloves.
Roof/work at heightUse fall arrest systems, secure ladders, and ensure stable footing.
Pressure & leakagePressure test system before final operation; check all joints.

Package Contents & Components

Unpack carefully and verify all parts against the packing list.

  1. Main Collector Assembly: Evacuated tube array mounted on aluminum frame.
  2. Mounting Brackets & Hardware: Stainless steel brackets, bolts, nuts, washers.
  3. Manifold & Header Kit: Pre-insulated manifold with inlet/outlet ports.
  4. Installation Template & Spirit Level: For accurate positioning.
  5. Sealant & Pipe Clamps: High-temperature sealant and stainless steel clamps.
  6. User Manual & Warranty Card: This document and registration materials.

WARNING! Do not discard packaging until all components are verified. Report any damage or missing parts immediately.

Pre-Installation Planning

Proper site assessment ensures optimal solar gain and system efficiency.

  1. Location: Select a south-facing roof or ground area (Northern Hemisphere) with minimal shading.
  2. Roof Structure: Verify roof can support collector weight (approx. 35 kg dry).
  3. Orientation & Tilt: Aim for true south azimuth; optimal tilt angle equals local latitude.
  4. Pipe Routing: Plan shortest possible pipe runs from collector to storage tank.
  5. Local Codes: Check building permits, zoning laws, and solar access rights.

CAUTION! Never install under trees, near chimneys, or where debris may accumulate.

Mounting & Assembly

Piping & Hydraulic Connections

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.

Electrical Connections (if applicable)

For systems with differential temperature controller and circulation pump.

  1. Turn off main power supply at circuit breaker.
  2. Connect pump and sensor cables to controller as per wiring diagram.
  3. Route sensor cables away from hot pipes and secure with cable ties.
  4. Ground all metallic components according to local electrical code.

Tip: Use conduit for outdoor cable runs and seal entry points against moisture.

System Commissioning

Follow this sequence to start up the system safely.

  1. Pressure Test: Fill hydraulic circuit and pressurize to 1.5x operating pressure for 30 minutes.
  2. Leak Check: Inspect all joints, manifolds, and connections for any signs of leakage.
  3. Fluid Circulation: Start pump manually; verify flow through collector and air purge.
  4. Controller Setup: Set temperature differential (ON: 6°C, OFF: 2°C) and high-limit safety.
  5. Insulation: Ensure all pipes, especially outdoor sections, are properly insulated.
  6. Final Inspection: Verify mounting security, pipe support, and clear access for maintenance.

WARNING! Do not expose empty collector to direct sunlight. Always fill with fluid before sun exposure.

Operation & Settings

Default controller settings are optimized for most installations. Monitor system for first few days.

Maintenance Guidelines

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.

Troubleshooting

SymptomPossible CauseCorrective Action
No hot waterPump not runningCheck power to pump; verify controller settings and sensor connections.
Low system pressureFluid leak or air in systemPressurize system; inspect for leaks; bleed air from high points.
Reduced efficiencyDirty tubes or scalingClean tubes with soft cloth and water; descale heat exchanger if needed.
Unusual noise from pumpAir lock or bearing wearBleed air; if noise persists, replace pump.
Fluid discolorationDegraded glycol or corrosionTest 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.
