Gas Boosted Integrated Plumbing Arrangement
Solar Circuit
It is imperative that both the collector hot and cold pipes must fall
continuously by at least 5º, or a 1 in 10 fall, to ensure proper drain back of
heat exchange fluid into the storage cylinder.
Each collector should be angled 10-15mm from horizontal towards the hot
outlet to ensure proper drain back of heat exchange fluid and to ensure that
the hot sensor is located in fluid when the pump is on. Likewise it is
essential that the collector connections are angled slightly downwards.
Failure to provide correct fall for the hot and/or cold pipes, collector(s) and
collector connections will result in incorrect operation of this appliance.
The solar hot and solar cold pipes between the solar storage tank and the
solar collectors MUST BE of copper and fully insulated with closed cell
polymer insulation or similar (minimum thickness 13 mm). Thicker insulation
may be required to comply with the requirements of AS/NZS 3500.4. The
insulation must be weatherproof and UV resistant if exposed. All
compression fittings must use brass or copper olives.
Plastic pipe MUST NOT be used, as it will not withstand the temperature of
the closed circuit fluid generated by the solar collectors.
Solar pipe work which is oversized or is too long can result in the drain back
system not operating effectively.
