5.3 Filling the Drycooler System
We recommend installing hose bibs at the lowest point of the system.
When filling a glycol system, keep air to a minimum. Air in glycol turns to foam and is difficult and time consuming to
remove. (Consider anti-foam additives.)
To fill the system:
1. Open all operating systems to the loop.
2. With the top vent(s) open, fill the system from the bottom of the loop.
The glycol will push the air out of the top of the system, minimizing trapped air.
3. Fill to approximately 80% of calculated capacity, then continue to fill slowly from this point, checking fluid
levels until full.
NOTE: For glycol solution preparation and periodic testing, follow manufacturer's recommendations. Do not mix
products of different manufacturers.
