Page 3: Installer Competency
1. Installer competency The installer must be an accredited installer, qualified in plumbing and knowledgeable with SANS 10106, the installation, maintenance, repair and replacement of domestic solar water heating systems and SANS 10254, the installation, maintenance, replacement and repair of fixed electric storage water heating systems. -
Page 4: Understanding The Split Pumped Circulation Method
4. Understanding the split pumped circulation method It is not always possible or convenient to install the solar water heater in a higher position than the solar flat plate collector or manifold of the vacuum tubes (thermosyphon circulation method), so the pumped circulation method has to be used. Split pumped circulation method Split pumped circulation method A circulating pump either 220V AC electrical or a 12V DC Pump with a PV Panel can be used. - Page 5 2. Direct frost resistant system - Close Coupled system (Thermosyphon circulation method) The Direct system with solar vacuum tubes is used in areas where the ambient temperature falls below 5°C and the water quality is good (less than 600ppm total dissolved solids/minerals. The water to be used from the solar water heater circulates through the manifold of the solar vacuum tubes, transferring solar energy into the storage tank.

Page 6: Features Of Solar Flat Plate Collector Panel
6. Features of solar flat plate collector panels • Black coated aluminium frame, 4mm toughened prismatic and non-reflective anti-hail tempered glass. • Durable copper waterway tubes. • Rubber seals ensure durability and reliability in extreme climatic conditions. • Semi-selective black chrome surface on copper substrate offers maximum absorption efficiency. -
Page 7: Roof Location Of A Solar System
For a flat roof, a flat roof frame with a load spread beam on the rear legs, that protrude at least 300mm past each leg, is available from Kwikot. • Careful inspection must be carried out to ensure that the roof can support the weight of the entire solar installation once it is filled with water. - Page 8 This procedure is not relevant for a split system. • A Pitch Roof Support with Panel Hooks is available from Kwikot. The hook is fed under the roof tiles and hooked around a strip of the roof brandering. •...

Page 9: Installation Of A Solar Water Heater System
All systems must be installed in accordance with SANS 10106 and SANS 10254, which must include a 400kPa Pressure Control Valve, Vacuum Breakers on both the cold water supply and the hot water draw off, Kwikot Drain Cock and Kwikot Safety Valve. Solar water heating systems can reach very high temperatures and it is recommended to install a thermostatic mixing valve. - Page 10 Installation Diagram: Direct Rear view Hot water Cold water Installation Diagram: Indirect 1.

Page 16: Filling A Solar System
In a split system, these pipes must be lead to the exterior of the building or roof, with a continuous downward fall and the outlets being left open to the atmosphere. NB! All Kwikot Kwiksol Solar Water Heating systems are supplied as pitched roof mounting and no flat roof frame is included. Flat roof frames are available as an optional extra. - Page 17 b. Indirect System - Thermosyphon circulation method • A dilution of Propylene Glycol and water has to be used in this system. • The dilution ratio’s as follows: Ambient temperatures in winter 5 °C to - 8 °C, one part Propylene Glycol to three parts water i.e. Propylene Glycol 1L with 3L of water.
-
Page 18: Draining An Indirect Solar System
11. Draining an Indirect Solar System The solution of Propylene Glycol and water must be drained from the system and replaced every three years. • Connect a 15mm (½”) flexible hose to the lever ball valve at the bottom of the solar flat plate collector panel. -
Page 19: Warranties - For The Homeowner
14. Warranties - for the homeowner* It is important to note that the warranty on the solar system installation is separate to that of Kwikot’s warranty on certain specified solar system products and components. 1. Installer warranty •... - Page 20 Damages due to loadshedding or power surges. Kwikot shall not be liable for any claims, losses, liabilities, damages, costs or expenses whatsoever and howsoever arising out of or in connection with the use, functioning or malfunction of the solar system or any part thereof including defects.
- Page 21 The tubes if cracked or broken from whatever cause, is not covered by the warranty. 15. To validate the warranty (Please register online) Kwikot has taken a significant step towards enhancing their customer service by introducing new Water Care product registrations. Through this new process, customers and installers can register their water...
