Notes
1) At lower relief valve settings, weights and capacities are higher. See Fill
Weight Table in Section 4.
2) Peaks of up to 4X continuous flow rates can be sustained for 5 minutes
if the vaporizer coils are allowed to thaw in between.
3) Height may vary on caster base models depending on specified wheel
diameter.
