- Page 7 NOTE Maximum heating output is based on average irradiation levels of 6000W/m /day prevailing in September- March and minimum Heating output is basedon average irradiation levels of 4000W/m /day prevailing in June/July and are for indicative purposes only. 3. WARNING AND SYMBOLS The installation of the solar system must be in accordance with the relevant requirements of the local authority building regulations as well as regulations for the prevention of...
- Page 8 Steam can escape from the expansion relief valve of the solar pump unit if the system is shut down. To avoid injuries an expansion relief valve must be connected to a collecting container with a hose line In order to ensure a seamless operation of the product, the safety valve should be cleaned periodically and checked for proper functions.
- Page 9 SOUTH OF THE EQUATOR 5. INSTALLATION Ultrasun UFS solar heaters are provided with drilled frames incorporating a support cross bar. On roofs the preferable mounting arrangement is by means of hooks affixed to the cross bar and secured to an appropriate mounting point on the roof beams. Suspension from the hooks is generally sufficient and fixed location is not necessary.
- Page 10 The units can be installed using a gravity system or pressurised supply. Pressurised systems are preferable as they give higher line pressures up to a maximum of 3 Bar. Note that in the case of pressurised supply hot and cold lines must be pressurised at the same pressure to ensure even temperature control.
- Page 11 The various installations are shown below: Flat roof Installation Pitch Installation Single Panel Installation Pitch Roof Bracket Assembly Step 1 Fit the top part of the solar tank bracket to channel 3 using M8 x 25 screws as shown.
- Page 12 Step 2 Select the holes in the angled section that are required for the specific installation. It is suggested that the holes be marked according to the specific type of installation required. Two types of angled sections are provided, a set for a single panel installation and a set for a double panel installation.
- Page 13 Step 4 Select which slotted holes the bottom angled section should be bolted onto. The selection should be based on the size of the solar collectors supplied. Two sizes are available: 2.0m² Approximately 2000 mm in length Ÿ 2.4m² Approximately 2000 mm in length Ÿ...
- Page 14 Step 6 Remove the tank feet supplied as shown below: Step 7 Fit the tank to the completed bracket frame as shown below on both sides. This step is to confirm that the two longitudinal channel beams are appropriately spaced to accommodate the tank.
- Page 15 Step 8 Fit the collectors to the bracket by placing them between the angled sections as shown below. Adjust the bottom angled section position by means of the slotted holes in order to fit the panel/s closely. Fasten the panels through the 6mm holes by means of the M5 x 16 self drilling screws.
- Page 16 The strips can be used to fit the system to the battens of the roof to provide additional support. Please note that longitudinal channel should coincide with or be as closely located to the rafters of the roof structure as possible. The strip fastening method is depicted below in section view.

Adjust the bottom angled section position by means of the slotted holes in order to fit the panel/s closely. Fasten the panels through the 6mm holes by means of the M5 x 16 self drilling screws.
- Page 23 ROOF SEAL This is a bonded seal to the roof surface which normally has a metal surround that can be easily manipulated to fit the profile of roof clading. Before applying the seal, a 25mm hole has to be drilled in the roof cladding. For metal roofs a hole saw for metal can be used while a core drill of 25mm suitable for concrete can be used on tiled roofs.
