COMMISSIONING

Closed Circuit Fluid
The water heater is supplied charged with closed circuit fluid and it is not
necessary to add further closed circuit fluid to the system. If the closed circuit
fluid has been completely drained or discharged from the solar circuit and
needs to be replaced, then the amount to be added is:
• 4.5 litres of concentrate, mixed with
• 11.5 litres of water.
It is necessary to undertake the solar circuit commissioning procedure if the
closed circuit fluid has been replaced.
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.
