Summarization of Contents
Important Information
Local standards
Installation must comply with relevant local standards and regulations.
Qualified Installer
Installation must be completed by qualified plumbing professionals.
Pressure and Temperature Control and Relief
Solar loop design for operation <600kpa; pressure release at no more than 1000kpa.
Water quality
Water must meet potable requirements and specific limits for solids, hardness, chloride, and magnesium.
Metallic corrosion
Copper & stainless steel susceptible to corrosion; limit free chlorine to 2ppm for spa/pool heating.
Freeze Protection
Incorporate low manifold temperature setting or use glycol-water mix for freeze protection.
System design and installation
Read instructions carefully before design/installation; ensure compliance with local regulations.
Lightning protection
Collectors require lightning protection; use a lightning rod 1.5m higher and 3m away.
Unpack and Inspect
Tube inspection
Check evacuated tubes for intactness and silver bottom; replace if damaged.
Heat pipes
Heat pipes are durable; ensure they are relatively straight before insertion.
Frame
Unpack frame kit; components for flat/low-pitched roofs may be packed separately.
Plumbing
Plumbing Connection
Connect manifold header to the system plumbing after frame and manifold attachment.
Choice of Piping Material
13mm or 15mm OD copper piping is typical; larger pipes increase cost and heat loss.
Pressure Levels
Install pressure release valves, expansion vessels; design for <600kPa with mains pressure.
Tempering value
Fit a temperature control device to reduce scalding risk, aiming for below 50°C.
Temperature Sensor Insertion
Insert sensor with thermal paste; seal port to prevent water ingress.
Wind and snow load
Consider wind resistance; standard frame withstands 120km/h winds and 30cm snow.
Heat transfer fluid
Use glycol/water mix for freezing protection, complying with local standards.
Stagnation and Overheating
Stagnation Prevention
Cover collectors or use heat dissipation for extended periods to prevent overheating.
Frame Installation
Figure size
Table detailing dimensions (A-H) for various SCM collector models.
Roof mounting
Mounting Components
Illustrations and labels for roof mounting components like front track and mounting sheet.
Installation Collector
Collector Direction
Face collectors towards the equator for optimal heat output, allowing up to 10° deviation.
Collector Angle
Install at an angle corresponding to latitude (15-85 degrees) for best heat pipe performance.
Location
Position collectors close to the storage cylinder to minimize pipe runs and heat loss.
Collectors connection
Use opposing spanners, moderate torque; seal compression fittings and use flexible pipes between collectors.
Maintenance
Cleaning
Clean evacuated tubes with soft cloth and soapy water or glass cleaner; high pressure spray is effective.
Leaves
Remove leaves accumulated between tubes to ensure performance and prevent fire hazards.
Broken Tube
Replace broken tubes promptly to maintain performance; system operates with broken tubes.
Precautions
Solar for Central Heating-Preventing Overheating
Consider spa/pool or heat dissipation device for central heating systems to manage summer excess heat.
Metallic components
Handle metallic components with gloves; be aware of potential sharp edges.
Evacuated tubes
Handle evacuated tubes carefully; they break if knocked or dropped. Wear gloves for broken glass.
High temperatures
Heat pipes can reach >200°C; collector header/pipes can reach 160°C. Exercise caution.
Media Liquid Filling
Air Purge
Purge air from the collector loop by running the pump at full speed, opening taps or loosening connections.
Plumbing Check
Confirm plumbing is leak-free and air is purged before installing heat pipes and evacuated tubes.
In proper order
Step-by-step guide for filling the medium liquid, closing valves, and connecting the expansion vessel.
