The Satchwell HOTFLO cistern type thermo-siphon solar system
1. SYSTEM INFORMATION / SYSTEM OVERVIEW The function of this Solar Water Heater (SWH) is to use the energy from the sun to heat water. The heating of the water is achieved via the Flat Plate Collector. The Flat Plate Collector is filled with water which is heated during the daylight hours and this hot water is stored in the main tank. The hot water rises in the Collector and is replaced by the cooler water which is at the lower level of the main tank. This cycle is repeated continuously throughout the day thus heating the water in the main tank. Cold water is supplied to the system as the hot water is drawn from the main tank. The cold water is supplied to the main tank via a header tank (cistern) which is mounted on top of the main tank. The cold water mains supply is connected to the cistern
The following minimum requirements are in addition and may be in duplication to any requirements as
specified by SABS or National Building Regulations.
6.3 (a)INSTRUCTIONS FOR SAFE AND CORRECT INSTALLATION
6.3 (a)(i) The Solar Water Tank, Collector & Frame (“The System”)
When viewed from the front or behind - No lean to left or right.
3
1. The Tank is a 100 liter vented cistern type and the system is classified as a split direct thermosiphon type
and is only to be used in coastal areas where no freezing is likely to occur
2. The flat plate must also not be used in water conditions where the dissolved solids / minerals are more
than 1000ppm (“hard water areas”) that can cause blockage in the panel (because of scale). As a
general rule, it is recommended, regarding the prevailing water conditions, that a inline water filter is
fitted during installation. This will ensure that the inlet valve does not become clogged.
3. Systems should be located as low as possible on roofs to reduce exposure to wind and/or a storm.
4. Systems must not be mounted with tanks on the lower inclination of the roof (where the weight of the
tank could cause The System to fall over backwards).
5. Wherever possible The System should sit on a single face of the roof rather than over the roof ridge.
6. Whenever possible The System should not straddle the roof ridge.
7. The System should be orientated as close due North as possible but must be between North East and
North West
8. The inclination of the Collector is 37° angular plus or minus 5° (32° to 42°).
9. The frame and system when viewed from the front or back, left or right must be vertical with no lean to
right or left. Check that the tank is horizontal, using a level. (Adjust the frame and mountings) Cross
braces supplied in the frame kit must be installed.
10. Frames of systems should be securely fastened to roof trusses with the weight of the tank evenly
distributed over a truss, and the front of the frame as close as possible to other roof trusses.
11. A load bearing beam/strap across the back and front legs of the system frame must be installed
protruding 300mm beyond each foot (ref: SANS1307:2012 Clause 4.5.5.1 a).
12. No sharp edges should ever rest against the roof materials and a foot or bearing plate should be utilized.
13. All frame connections into roof must be properly waterproofed.
14. Any adjustment to the legs beyond the pre-made adjustment holes must be made corrosion proof.
Where frames have been cut, (for example to accommodate inclination) the bare cut must be treated
with anti rust / corrosion paint.
15. The cold water cistern should lie as close to vertical as possible, but must not be off vertical by more
than 5˚.
16. Lids of cistern must be securely fastened to avoid blowing off in a wind, with the self threading screws
provided.
17. The overflow must be unobstructed and allow a safe discharge of water in the event of a failure.
18. The cistern valve float level is set in the factory and must not be altered.
4
19. All external pipe work must be copper or stainless steel, including cold water feeds to cisterns or header
tanks.
20. No plastic pipe to or from the system is allowed on the system, unless it is inside the building.
21. Isolating valves of the cold water feed to the SWH system must be a lever type, easily accessible and
below shoulder height.
22. Taps must be properly secured to the wall and suitable for the use of hot water.
23. Tempering valves must be fitted to comply with required maximum heat into the home (normally 60°
Celsius) and must be suitable for low pressure installation.
24. Cold and hot water to the mixing valves must be balanced pressure. High pressure one side (cold water)
/ low pressure (hot from the tank) do not work.
25. Where pipes go through roofs all holes must be properly waterproofed to avoid leaks.
26. All plumbing connections/fittings must comply with SABS requirements.
27. The inlet pipe must be supported correctly so as not to create a load on the cistern tank inlet.

6.3 (d) SAFETY PRECAUTIONS
Safety Installation Requirements For Cistern Type H ot Water System:
• Factory labels and markings may not be altered or rendered unreadable.
• All safety regulations apply when installing a system and all installations are to be done in accordance with
the Occupational Health & Safety Act and Regulations 85 of 1993 requirements and any relevant local
authority bylaws.
• Assess the risks specific to the area of installation and eliminate or reduce to an acceptable level to fall
within the H&S requirements, before starting with the installation.
• Assess weather circumstances to determine if safe installation will be possible e.g. high winds, rain, lighting,
etc.
• Inform home owners or building occupants of the time and place of work to be carried out as well as risks
involved. Ensure occupants are aware of access constraints and safety implications to them. Cordon off area
and ensure pets are secured.
• Beware of overhead power lines coming through the roof, crossing the roof overhead, or wiring running
through the ceiling, in the area where the installation need to take place.
• Ensure persons doing an installation are competent and in suitable physical condition. All personnel working
on an installation of a solar hot water system must be issued with the appropriate safety equipment e.g.
goggles, hard hats, gloves, safety wear, etc. and trained in their use. Be sure to comply with the specified
degree of protection.
• Working at heights should only be undertaken by suitable qualified personnel, using the proper safety
equipment. Installers must be trained and conversant with the assessment of height hazards, working at
heights safety procedures and assessment of safety equipment e.g. scaffolding, ladders, harness, etc.
• Scaffolding and safety equipment must be installed by certified personnel and be signed off accordingly.
• Water temperature can reach boiling point and the collector can reach stagnation temperatures of over
70°C. Shade collector during installation to prevent heating.
• Care should be taken not to touch the pipe work connecting the solar storage tank and the solar collector,
very high temperature hot water can be generated by the solar collector under certain conditions and will
flow through the pipe work from the solar collector to the solar tank.
• Take care when handling collector during installation to prevent breakage to glass and injury. Safety goggles,
work wear and gloves must be used to reduce the risk of injury.
Also, ensure to: • check that all bolts and nuts are tight on the Support Stand.
