INSTALLATION
Remove the packing from the top and bottom of
the FloodSafe
® that is used to protect the floats
during shipping. Install the basket per step 6 in
the REASSEMBLY section on page 3. The
installation of the FloodSafe
® is important for its
proper operation. The FloodSafe ® should be
installed plumb in the vertical position with the
basket facing downward. Thread or bolt the
FloodSafe
® to the outlet of an air valve using
standard connection practices. The bolting for 6"
and larger devices conforms to ANSI B16.1 for class
125# flanges. An optional mounting bracket (80)
may be used to mount the device to wall supports.
Flanged connections should only be mated with flat-
faced pipe flanges equipped with full-face or ring
type resilient gaskets. The bolts should be tightened
in gradual steps using the crossover method.
Recommended torque values are given in Table 1.

FLOODSAFE ® CONSTRUCTION
The standard FloodSafe ® is constructed of ductile
iron. Stainless steel type 316 float checks are the
only moving elements and seal against a low
hardness resilient seat. The general details of
construction are illustrated in Figure 3 and identified
in Table 2.
