6.0 GLYCOL SYSTEMS<br />
6.1 Glycol Concentration<br />
The system must be fi lled with water <strong>and</strong> the appropriate amount of ethylene or propylene glycol<br />
to protect against winter freezing. To achieve the approximate glycol concentration, it is necessary<br />
to know the total system volume. The total system volume consists of the fl uid cooler volume, the<br />
evaporator unit volume <strong>and</strong> the volume of the inter-connecting piping.<br />
The following tables can be used for arriving at an approximate system volume. After installation,<br />
the glycol percentage should be checked. The glycol percentage should be checked at regular<br />
intervals to ensure against freeze protection.<br />
