OPERATION, MAINTENANCE AND INSTALLATION

INTRODUCTION

This manual will provide you with the information to
properly install, maintain and ensure a long service
life for the FloodSafe
FloodSafe
release or air/vacuum valve to prevent cross
contamination of the potable water system due to
flooding and malicious tampering as described in
ASSE Standard 1063. The FloodSafe
with two float checks that are open during normal
pipeline operation to allow full airflow in both
directions. The float check(s) will rise and seal when
the surrounding atmosphere is filled with water.

is to be installed on the outlet of an air

RECEIVING AND STORAGE

Inspect the FloodSafe
shipment. Unload all devices carefully to the ground
without dropping. Remove all blocking material
inside of the metal basket.

The devices should remain boxed, clean and dry
until installed to prevent weather related damage.
For long term storage greater than six months, the
rubber seat should be coated with a thin film of FDA
approved grease such as Lubriko #CW-606. Do not
expose rubber seat to sunlight or ozone for any
extended period.

DESCRIPTION OF OPERATION

The FloodSafe
lower chamber and upper, redundant chamber. Both
chambers contain identical float checks that are
open during normal pipeline operation and allow full
airflow in both directions. If flooding occurs the
lower float check will rise, preventing floodwater from
reaching the outlet of the air valve and subsequently
the pipeline. If the lower float check fails the upper,
redundant float check will close preventing
floodwater from reaching the air valve. The basket
screen prevents debris from interfering with the
operation of the FloodSafe

basket facing downward. Thread or bolt the
FloodSafe
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 flat­faced 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.

The use of excessive bolt torque may damage

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
