The closed circuit fluid contains food grade additives (rust inhibitor, anti-freeze agent,
colour) and is harmless to the environment. However, it is good practice to recover any
excess closed circuit fluid and remove from site for appropriate disposal.
Warning: Although non-toxic, the following first aid advice and procedures
should be followed if the closed circuit fluid concentrate comes into human
contact or is spilt:
• Swallowed - give milk or water and seek medical attention.
• Eyes - wash with running water.
• Skin - remove contaminated clothing and wash skin with water and soap.
• Inhaled - seek fresh air, rest and keep warm.
• Spilt - immediately remove contaminated clothing, stop leak source, absorb with a
dry agent and eliminate any ignition sources nearby.
Pre-commissioning Warnings
It is recommended to conduct the solar circuit commissioning procedure with
the solar collectors covered, otherwise during the commissioning and
checking procedure of the solar circuit, the closed circuit fluid may
experience solar gain as it passes through the solar collectors. This will
increase both the temperature and pressure of the closed circuit fluid and
vapour inside of the solar circuit.
The electrical supply must be switched off before the solar circuit is opened
either at the solar circuit relief valve or at the compression nut on either of the
solar hot or solar cold pipes at the top of the solar storage tank.
If it is necessary to open the solar circuit at the solar circuit relief valve or at
the compression nut on either of the solar hot or solar cold pipes at the top of
the solar storage tank, then care must be taken so as not to be scalded by
either the closed circuit fluid or the vapour escaping from the solar circuit.
Pre-Commissioning Notes
1. Before commencing the solar circuit commissioning procedure, check the solar cold
and solar hot pipe work to ensure:
• There is a continuous fall from the solar collectors to the solar storage tank of a
minimum 5° (1 in 10 grade).
• The maximum recommended pipe length is not exceeded.
• The maximum height from the base of the solar storage tank to the solar collector is
not exceeded.
Rectify the solar pipe work if there is either insufficient fall or not a continuous fall of
at least 5° from the solar collectors to the solar storage tank or if either of the
maximum pipe length or maximum height of the system has been exceeded, before
commencing the solar circuit commissioning procedure (refer to Maximum Total Pipe
Lengths table on page 12).
