NOTES
1. Schematic representation shown. Do not use for specific connection locations.
2. Install a 35 mesh straine r, in an easily accessible location, on the water/glycol
supply to prevent particles from entering the heat exchange r. Strainer bypass
valves are reccomended to allow the strainer to be cleaned while maintaining
flow to the cooling unit.
