Commissioning of system

1.1 Commissioning - General
Solarflo TM system uses an indirect sealed primary circuit which
must be filled with the heat transfer fluid provided. This is
mixed to the appropriate strength (40% glycol/60%water) and
should not be diluted further. Use only the fluid supplied.
Additional solar fluid is available in 10 litre containers - Baxi
Sales Number 5130651.
DO NOT mix the fluid with other types.
The system should be filled when there is no direct radiation
from the sun. If direct radiation is likely to occur the
collector(s) should be shaded by covering them during filling
and flushing.
Although the solar heat transfer fluid is non corrosive and
biodegradable appropriate precautions should be taken when
handling.
- Wear protective gloves and goggles.
- Wash with soap and water if the fluid comes into
contact with skin.
- If fluid gets into eyes, rinse immediately with large
quantities of clear running water.
- A full safety and specification sheet can be obtained
by request.
The solar heat transfer fluid must be pumped into the system.
The pump can be electric or manual but must be capable of
producing a pressure of at least 2 bar.
The system should be thoroughly flushed with heat transfer
fluid to remove any contaminants in the solar primary circuit
prior to filling with the heat transfer fluid.
