󱚡 WARNING

Failure to safely control system pressure levels could result in the dangerous rupture or

explosion of system components. This may cause serious scalding injury and damage.

3.20. Water Quality & Inspection

a) In direct flow systems, the water flowing through the manifold header must qualify as potable water and

meet the following requirements:

Total dissolved solids < 600 p.p.m. Total hardness < 200 p.p.m.

Chloride < 250 p.p.m. Free Chlorine < 5 p.p.m

Magnesium < 10 p.p.m. Sodium < 150 p.p.m

pH 6.5 - 8.5 Electrical conductivity < 850 μS/cm

b) In areas with “hard” water (>200ppm), lime scale may form inside the header pipe (direct flow), or inside

the storage tanks/heat exchanger (closed loop). In such regions, it is advisable to install a water softening

or anti-scale device to ensure the long term efficient operation of the solar water heating system.

✖ Failure to install and maintain a water softening device in an area with “hard” water may void warranties.

c) Any heat transfer fluid MUST be GRAS (Generally Recognized As Safe by the FDA) or a dual wall heat

exchanger with leak detection must be used. Such liquids should be checked on a periodic basis, ideally

once annually, but no less than once every 3 years, or as determined appropriate given experience in that

climate and as may be specified by the manufacturer. Refer to 3.31 for more information on heat transfer

fluids. As a general rule the following tests should be completed (see also sections 11.5 & 11.9).

i) Check for cloudiness or “sludging” that would indicate fluid breakdown

ii) Check pH. It should be within the range specified by the manufacturer

iii) Use a hydrometer to check freeze protection level

✖ Performance losses due to scale formation is not eligible for warranty claims.

✖ Performance losses or any component failure related to fluid degradation are not eligible for warranty claims.

3.21. Metallic Corrosion

a) Chloride: Copper is susceptible to corrosion, especially if high concentrations of chloride are present.

The solar collector may be used for heating of spa or pool water, but levels of free chlorine must not exceed

5 ppm, otherwise the copper header may corrode.

b) Copper Corrosion: On rare occasions, corrosion of copper pipe may occur causing blue staining at the

point of hot water usage. This corrosion is generally due to either poor water quality or electrical current on

the copper pipe due to poor grounding or contact with some electrical appliance or electrical source causing

galvanic reactions.

c) Air Pollutants: Air pollutants such as acid rain, emissions from industrial exhausts and various

chemicals in the air may cause corrosion of the collector casing and frame. A site inspection should be

completed to identify any potential pollutants prior to installing system.

d) Coastal Regions: The 439, 301 and 304 grade stainless steels used for Apricus solar collector frames,

clips and fasteners are corrosion resistant to salt water. Installation near the sea is not normally a problem.

In some coastal regions, the combination of salt spray and living sea microbes can result in rapid corrosion

of the stainless steel. In such cases, the frame needs to cleaned thoroughly and sprayed with an enamel

paint to provide protection (zinc based paint is NOT suitable).

e) Refer also to water quality requirements above in section 3.20.

✖ Corrosion related damage is not eligible for warranty claims.
