APPENDIX 3
REQUIREMENTS FOR AQUATIC SOLAR WATER HEATING SYSTEMS
1. Construction Materials
Materials used to construct the system shall not contaminate water, or be susceptible to corrosion under normal service conditions. 2. Temperature Control System
A temperature control system shall be installed. The temperature control system shall ensure pool users will not be exposed to water temperatures exceeding 380C. Thermostats used for this purpose shall be of a type that cannot be adjusted without the use of tools. 3. Water Pumping System
Solar pool heating systems shall be installed on a plumbing circuit that is separate and independent from the filtration system. A filter or strainer shall be installed to remove solids and/or debris, and shall be located upstream of the pump. 4. Suction Outlets
Suction outlets shall be installed in the wall of the pool at least 500mm above the floor level. Suction outlets shall be installed in accordance with the provisions of Clause 3.2.6 of this Code. 5. Drainage System
An automatic or manual drainage system shall be installed, to enable all water to be emptied from the system when not in use. The drainage system shall incorporate a back-flow prevention valve, to prevent water draining back to the pool through the filter. |
