(High Pressure Steel Tubing - .049" wall thickness)
(4)
3/8” Bite Fitting (Compression) x 1/4” Male Adapter
(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
INSTRUCTIONS:
-
Screw
the Float and 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
of an inch of each other for proper installation. Due to the many tank
configurations,
it is the installer's 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 a 4” bung of the
tank and
tighten
the Tank Bushing. (See Important Notes Below)
-
Screw
a 2” nipple into the top of the Tank Bushing.
If a drop tube is required, it may now
be installed through the 2” nipple.
-
Install
the discharge side of the Shutdown Valve on the 2” nipple. Align the Valve
inlet for the supply pipe.
-
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
refrigeration grade 1/4” OD tubing, following color coding for the Vent
and Pressure 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
