Glycol is recommended when a supply water temperature of +5°C or below is required or
when static water can be exposed to freezing temperatures.

Waste glycol needs to be handled responsibly, recycled or turned over to professional
personnel for correct disposal. Most anti-freeze manufacturers recommend that used anti-
freeze be collected and disposed according to Local Legislation. Waste glycol should NOT be
drained onto the ground, rainwater drainage system or natural waters.
If the glycol contains heavy metals or other contaminants from gas or oil, the level of hazard
posed by the glycol is increased and could be characterised as hazardous waste.
STEPS IF GLYCOL IS RELEASED/SPILLED
Small spill - soak up with absorbent material.
CAUTION
Large spill - contain spill and pump to suitable container for disposal.
