Basin

The basin is constructed from one of the following materials of construction and the following maintenance applies to all basin
materials of construction.
•
Galvanized steel
•
TriArmor Corrosion Protection System
®

Welded Type 304 stainless steel

Water Levels

•
Height is measured from unit's base (mounting point) to water level. Depth is measured from the interior basin floor to
water level.
•
The operating water level in the basin will vary with system thermal load (evaporation rate), the bleed rate employed, and
the make-up water supply pressure.
•
The make-up valve controls the operating level, which should be maintained at the levels shown in Table 3.
•
Check the operating water level monthly and readjust the float when necessary to maintain the recommended operating
level.
