(1)
4 1/2' x 1/4" Copper Tubing
SUPPLY PUMP MUST BE CAPABLE OF MAINTAINING 7 psi FLOWING PRESSURE AND
HAVE A FUNCTIONING BYPASS RELIEF VALVE SET AT 50 psi MAXIMUM.
INSTALLATION
-
Screw
the Float & Float Arm into the Pilot Valve.
-
Screw 3/8" Bite fittings into the
Pilot Valve without pipe sealant.
-
Screw 3/8" Bite fittings into the
bottom edge of the Tank Bushing without pipe sealant, the side that will
be inside the tank after the bushing is installed in the tank bung.
-
Cut
the Gauge Tubing to the appropriate length.
The two lengths of tubing must be within 1/64
an inch of each other for proper installation.
(Due to the many tank configurations, it is the
installers responsibility to calculate the actual tubing length for the
specific installation.
The actual shut-off level of this valve is at the poppet of the Pilot
Valve.)
-
Matching
Blue-to-Blue and Red-to-Red, install the Gauge Tubing from the bottom of the
Tank Bushing to the Pilot Valve.
-
Test Tank Bushing / Pilot Valve Assembly.
-
Apply
air pressure (30-50 psi) to RED port on top of the Tank Bushing while the
Float is in the down position. Air
should flow through the tubing, Pilot Valve, and back out the BLUE port on top
of the Tank Bushing.
-
While
air pressure is being applied, squeeze the Float Arm Clevis upward to compress
the poppet. Air should stop
flowing out the BLUE port.
-
Apply
air to BLUE port while the Float is in the down position.
It should flow through the RED port.
Squeeze the Float Arm Clevis upward. The
air should stop flowing through the RED port and flow through the clearance
around the poppet.
-
IF OFP
CONFIGURATION INCLUDES OPTIONAL FUNCTIONAL TEST KIT, INSTALL FTK AT THIS
POINT.
-
Slip
the Tank Bushing/ Pilot Valve/ Float Assembly into the 4” bung of the
tank and tighten the Tank Bushing. (See Important Notes Below)
-
The discharge of the
Shutdown Valve is 3" female pipe thread. It must be installed in a
bung opening that is separate from the Tank Bushing. If the bung is
not a 3" bung, a reducing bushing must be installed in the tank bung. Screw
a 3” nipple into a 3” bung on top of the tank. If a drop tube is required,
it may now be installed through the 3” nipple.
-
Install
the three (3) 1/4” Compression x 1/4” Male Adapter Straights into the top of the Tank
Bushing. Install the two (2) 1/4” Compression x 1/8” Male Adapters Elbows into the
side of the Shutdown Valve.
Install one
(1) 1/4” Compression x 1/8” Male Adapter Elbow into the vent on top of the
Valve.Install
the discharge side of the Shutdown Valve on the 3” nipple. Align the inlet
for the supply pipe.Screw
the discharge side of the Shutdown Valve on to the 3” nipple.
-
Install
refrigeration grade 1/4” OD tubing, following color coding for the Vent and
Fuel Tubing connections between the
Shutdown Valve and the top of the Bushing.
-
Install
pipe from the inlet side of the Shutdown Valve to the appropriate connections
terminating with a Dry Disconnect.
-
Care
should be taken to properly align Float in tank to stay clear of all
obstructions. (The
Float runs parallel with the RED and BLUE marks on the top of the Bushing and
faces in the direction of the RED marking.)
-
All threads (except where
instructed otherwise) should be doped using a suitable UL approved pipe
sealant.
