Val-Matic 1-16 in. FloodSafe Inflow Preventer - Manual (Page 4)

WARNING:
Close the isolation valve underneath the
adjacent air valve. Failure to close the isolation
valve may allow discharge of air into the
FloodSafe
® and cause bodily injury.
MAINTENANCE
The FloodSafe ® requires no scheduled lubrication or
maintenance.
INSPECTION: The FloodSafe
® may be checked for
debris by following the disassembly and reassembly
instructions. The seat may be checked for cracks or
tears. The float check may be inspected for
indentations or deep scratches on the top sealing
portion.
TROUBLESHOOTING
Several problems and solutions are presented below
to assist you in troubleshooting the FloodSafe
® in an
efficient manner.
 Air valve water discharge: It is normal for air
valves to discharge some water before closing.
Continuous leakage requires maintenance of
the adjacent air valve.
 Leaks during field test: Clean and inspect the
resilient seats and the float checks.
DISASSEMBLY
Note: If the FloodSafe is connected to the optional
mounting bracket (80), the FloodSafe™ will need to
be removed from the bracket.
1. Remove the basket (12).
a) On sizes with side taps, use an allen wrench
to loosen the screws holding the basket to
the lower chamber (1B). Rotate the basket
counterclockwise and pull the basket down
and away from the chamber.
b) On sizes without the side taps, use an open-
end wrench to remove the bolts holding the
basket to the lower chamber flange.
2. Remove the lower chamber (1B) by removing
the bolts (7A) and nuts (7B) joining the two
chamber halves.
3. Remove the seat (4) by pulling it upward and out
of the chamber. Tilt the chamber to remove the
float check (5).
4. The upper chamber is removed in the same
manner as the lower chamber. Remove the
bolts joining the chamber and cover using care
to support the chamber. The seat and float
check can be removed in the same manner as
before.
REASSEMBLY
All parts must be clean. Worn or damaged parts
should be replaced during reassembly.
1. Install the float check (5A) into the chamber
(1A).
2. Insert the seat (4A) with the raised circular
surface facing down into the chamber (1A).
3. Connect the upper chamber (1A) to the cover (2)
with the bolts (7A) and nuts (7B) using the cross
over method. One washer is installed under the
head of the bolt and one underneath the nut.
4. Install the float check and seat into the lower
chamber per steps 1 and 2.
5. Connect the lower chamber (1B) to the upper
chamber (1A) by using the bolts (7A) and (7B).
One washer is installed under the head of the
bolt and one underneath the nut.
6. Install the basket (12) to the lower chamber (1B).
a) On sizes with the side taps, start the socket
head cap screws into the lower chamber
flange. Install the basket by pushing upward
and turning clockwise. Tighten the socket
head cap screws to secure the basket.
b) On sizes without the side bolts, install the
bolts through the bottom flange and into the
tapped holes on the basket screen. One
washer is used underneath the head of the
bolt.
CAUTION:
The FloodSafe ® chambers may be heavy.
Support the chambers when removing the
bolts in order to prevent bodily injury.
