2 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 evacuated glass tubes. The evacuated glass tubes 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 evacuated glass tubes 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 an integral direct thermo siphon type and can be used where freezing is likely to occur 2. The system must not be used in areas where the water conditions are outside the parameters as stated below. Using the system in areas with water conditions outside these parameters ( hard water areas ) will cause damage to the system (blockage in the system because of scale) and will not be covered as a warranty claim. PH Total Dissolved Solids 600 mg/l Calcium carbonate Level(Hardness) 200 mg/l Chlorides 250mg/L Magnesium 10mg/L 3. Recommended, regarding the prevailing water conditions that an inline water filter is fitted during installation. This will ensure that the inlet valve does not become clogged. 4. Systems should be located as low as possible on roofs to reduce exposure to wind and/or a storm. 5. 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). 6. Wherever possible the System should sit on a single face of the roof rather than over the roof ridge. 7. Whenever possible the System should not straddle the roof ridge. 8. The System should be orientated as close due North as possible but must be between North East and North West 9. The inclination of the Collector is 35 angular plus or minus 5 (30 to 40 ). 10. 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. (Refer section 4 page 9) 11. 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. 12. 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 a). 13. No sharp edges should ever rest against the roof materials and a foot or bearing plate should be utilized. 14. All frame connections into roof must be properly waterproofed. 3

4 15. 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. 16. The cold water cistern should lie as close to vertical as possible, but must not be off vertical by more than Lids of cistern must be securely fastened to avoid blowing off in a wind, with the self-threading screws provided. 18. The overflow must be unobstructed and allow a safe discharge of water in the event of a failure. 19. The cistern valve float level is set in the factory and must not be altered. 20. All external pipe work must be copper or stainless steel, including cold water feeds to cisterns or header tanks. 21. No plastic pipe to or from the system is allowed on the system, unless it is inside the building. 22. Isolating valves of the cold water feed to the SWH system must be a lever type, easily accessible and below shoulder height. 23. Taps must be properly secured to the wall and suitable for the use of hot water. 24. 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. 25. 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. 26. Where pipes go through roofs all holes must be properly waterproofed to avoid leaks. 27. All plumbing connections/fittings must comply with SABS requirements. 28. The inlet pipe must be supported correctly so as not to create a load on the cistern tank inlet. 4

10 Unscrew the cap from the Adjustable socket to allow the EVT to slide through it with the open end facing the geyser. Fill the EVT with water. This is to prevent the EVT from overheating in the sun while the installation is in progress. Use soapy water to spray onto the open end of the EVT. Also spray soapy water into the rubber seal in the geyser. (This helps to lubricate the EVT during fitment into the geyser.) Now slide the EVT into position of the selected hole in the geyser. The first part (about 35mm) will insert fairly easy. Thereafter it will become more difficult, this is normal. Insert the EVT for the last section into the geyser with a twisting while pushing it in motion. Be careful not to damage the seal in the geyser!!! Note: The seals are designed to protrude from the geyser. This is normal, but it could get pushed in during transit or handling. Before inserting the EVT pull the seal gently forward until resistance is felt. This means that the seal s inner shoulder has properly seated against the inside sealing surface of the geyser. Line up the bottom end of the EVT with the Adjustable socket (D4). The pointed section of the EVT should just protrude from the female section of the Adjustable socket. Now screw back the male part of the adjustable socket taking EXTREME care not to damage or break the pointed section of the EVT!! Note: Damaging or breaking this pointed section will render the EVT ineffective. Continue to complete the remainder of the EVT s in the same manner. 10

11 6.3 (b) INSTRUCTIONS FOR SAFE AND CORRECT OPERATION OF COMPLETE SYSTEM Once the Safety Precaution list below ((6.3 (d)) has been checked proceed with the following steps: 1. Connect the cold water supply line and hot water to user line as marked on the schematic. 2. Make sure that all systems connections are fastened. 3. Fill the geyser with potable water ensuring that there are no airlocks. 4. Check carefully for leaks and fix if any. 5. Make sure the pipes going out of the collector to the geyser are on a constant slope upwards. 6. Best performance achieved with well insulated pipes. The hot line from the collector must be insulated to reduce heat losses. 7. The geyser is designed to be installed in a horizontal position only - a vertical installation must not be attempted and will also invalidate the warranty. 8. The geyser must not be wall mounted a wall mounting is unsafe and will also invalidate the warranty. 6.3 (c) INSTRUCTIONS FOR REGULAR MAINTENANCE (Please read and note a safety instruction that follows) Regularly inspect the solar system for any leaks or damages Turn off main water supply and open Drain cock to flush tank with fresh water once a year to flush any settled sediment. Clean or replace additional inline water filter, recommended during installation. For optimum performance clean and wipe the EVT every 3 months, removing dust, bird droppings, leaves etc. Use a soft cloth or mop. Problem Possible Cause Corrective Action 1 Constant water over flow from header tank. 2 No hot water although the weather has been sunny. Float valve does not shut off water when the header tank is full. No mains water supply. Check float valve is operating correctly. Check for debris in the float valve that might be preventing the float valve from shutting off. Check and restore mains water supply. Check that the inline filter and strainer (in inlet of valve) are clean and free of debris. In case of emergency, like broken EVT or leaking tank, close cold water supply to system immediately and call the authorized service provider for rectification of the problem. 11
