OMPONENT UPTURE
The air actuated control valve, and all of the fill piping
and connections between the air actuated control
valve and the fluid delivery pump, must be designed
for use with pumped delivery, and be able to handle
the maximum pressure produced when the pump
continues to operate after the air actuated control
valve closes.
The maximum working pressure of the components
in the fill piping may vary. Over pressurization of any
component may cause them to rupture, resulting in
property damage and serious injury, such as skin
injection, or injury from splashing fluid.
To reduce the risk of injury and property damage
from component rupture:
• Be sure to know the maximum working pressure
of each component in the system
• Never exceed the maximum working pressure of
any component in the system
• Only connect fluid delivery pumps which are able
to be operated with a closed outlet
• Only connect fluid delivery pumps with a
maximum outlet pressure lower than the
maximum rated pressure of the system
Pressure Relief Procedure
f
The equipment connected to the air control solenoid
valves may stay pressurized until pressure is
relieved. To help prevent serious injury from
pressurized fluid, such as skin injection, splashing
fluid, and moving parts, follow the Pressure Relief
Procedure for the connected equipment when you
stop dispensing and before cleaning, checking, or
servicing the equipment.
1. Turn off the bleed-type master air valve located
upstream of all connected equipment.

2. Turn the Fluid Defender keyed power control off to
de-energize the connected air control solenoid
valves.
3. Follow the pressure relief procedure for all
connected equipment, such as pumps and
dispense valves from your component instruction
manuals.
Installation of Air Control
Solenoid Valves
1. Mount the air control solenoid valve, using the two
mounting holes, to a sturdy mounting surface.
NOTE: Mounting inline with hard plumbing is
acceptable.
2. Connect Port 1 to the air supply (F
3. Connect Port 2 to the downstream controlled
equipment. (F . 4).
IG
Install the user supplied connected equipment
downstream of the air control solenoid valve
following manufacturer requirements.
4. Install the muffler into Port 3. Port 3 is an exhaust
port. Do not plug the port because when the air
control solenoid valve deactivates under alarm
conditions, the downstream air pressure vents
through Port 3 (F . 4).
