5.0 GLYCOL SYSTEMS
5.1 Glycol Concentration
Thesystemmustbelledwithwaterandtheappropriateamountofglycol(eitherethyleneorpro-
pylene) to protect against winter freeze-up. To achieve the approximate glycol concentration, it is
necessarytoknowthetotalsystemvolume.Thisconsistsofthesumoftheuidcoolervolume,the
evaporator unit volume and the volume of the inter-connecting piping.
The following tables can be used for arriving at an approximate system volume. After installation,
the glycol percentage should be checked. The glycol percentage should also be checked at regular
intervals to ensure freeze protection.
