Figure 5.3
Power LED:
LED will be solid green when power is present
Position Indicator:
5 LEDs indicate valve position. One for full close (red at far right), one for full open (green
at far left), three yellow for 25%, 50 %, and 75% open. Two LEDs will light when position is
between two percentages.
Note: The position indicator will lose position if the manual override is used while the power is
off. Position location is restored after the first cycle of electric operation.
Control Buttons:
Manual Mode
When OPEN or CLOSE button is pressed, valve opens or closes until button is released.
Automatic Mode
When OPEN or CLOSE button is momentarily pressed, valve opens or closes fully.
During valve movement if STOP or the other direction is momentarily pressed the motor will
stop.
Changing Modes (Unit is shipped from factory in the Auto Mode)
Press CLOSE and STOP buttons together and hold for 3 seconds to change to Automatic
Mode.
Press OPEN and STOP buttons together and hold for 3 seconds to change to manual mode.
5.4 AIR VENT AND WATER DRAIN
CAUTION
Loss of prime can interrupt water flow and cause injury or death. Always bleed out air with air
valve to prevent possible loss of prime.
The BIV and Jumbo BIV come with an Air Vent/Drain situated on the side of the PRV pad. The BIV has a second plugged port on the
opposite side of the pad. An additional port on both the BIV and Jumbo BIV is located along side of the gearbox. To use a different
port position, relocate the factory supplied drain valve or install an additional drain valve. If the Air Vent/Drain is being relocated,
use a ¾”NPT plug to seal the empty port. The barb fitting must be removed from the Air Vent/Drain body to install and replaced once
the Air Vent/Drain body is tightened.
5.5 PRESSURE RELIEF VALVE
WARNING
Do not leave the pressure relief valve in the OFF position. The pressure relief valve is disabled
in the OFF position and offers no protection against over pressurization. The OFF position may
be used for controlled pump testing but should not be used for service conditions. Exercise
great care to avoid water hammer or other pressure spikes when the pressure relief valve is in
the OFF position.
WARNING
The Pressure Relief Valve may be damaged if frozen while containing significant amounts of
water. Such damage may to difficult to detect visually and can lead to possible injury or death.
Any time the Pressure Relief Valve is subject to possible damage due to freezing, it must be
hydrostatically tested by qualified personnel before being considered safe for use.
LDH valved appliances may be equipped with a pressure relief valve that can be set to any pressure between 90 and 300 psi. Its
function is to protect the pump and supply hose from excess pressure. A piece of hose or tubing may be mounted on the round
spout to direct water coming out of the relief valve away from the device. The relief valve may be mounted with its opening facing
the front, back, right, or left. To change the orientation of the relief valve, remove the four 7/16” bolts (5/8” wrench) on the corners of
the relief valve flange, orient the valve in the desired position, and replace the bolts. Use thread-locking compound on the threads
of the bolts to prevent them from vibrating loose.
See
LIA-202
Pressure Relief Valve Instructions for Safe Operation and Maintenance.
5.5.1 RELIEF VALVE SETTING PRESSURE
To set the relief valve pressure turn the adjusting
screw on the relief valve housing until the surface
of the screw is even with the desired pressure. A
9/16” (14mm) socket or a 1/4” Allen wrench may
be used to turn the adjusting screw. The Pressure
relief valve should not be disabled (IE: capped,
plugged, or set to the OFF position) for normal
service conditions. Disabling the relief valve may
result in system damage or hose rupture if the
system exceeds operating limits. The pressure
relief valve meets the requirements of NFPA 1901.
