5.2.1 SUPPLY MONITOR FROM THE SIDE A INLET
Blue shading in Figure 5.2.1 indicates water delivered to the monitor from the Side A
Inlet. When a water supply is introduced from a standpipe or hydrant below the Booster,
the swing-check valve (clapper) within the Booster will remain closed to keep Port C3
sealed. Clapper position can be verified visually by viewing the position indicator shown
in Figure 5.1. The water supply will flow through the Booster to the monitor with minimal
pressure loss as described in Section 6.0 .
To boost the discharge pressure or introduce foam solution to the monitor, (see section
5.2.2) .
5.2.2 SUPPLY MONITOR FROM LDH INLET PORT C3 (BOOST PRESSURE OR INTRODUCE FOAM)
Blue shading in Figure 5.2.2A and B indicates water delivered from
the standpipe or hydrant below, and purple shading indicates water
that has been supplemented by a pump and/or foam injection device.
To boost the discharge pressure or introduce foam solution to the
monitor, follow the steps below.
When the water supply is from an HUM installed below the Booster,
see LIZ-055 for complete instructions. For water supplies from other
sources, follow the instructions below.
1. Close valve installed upstream of the Booster Side A Inlet.
2. Connect a hose from the water supply to LDH Inlet Port C3 of
the Booster. Pumps and/or foam injection devices should be
connected in this hose line.
3. After all connections have been made, introduce the water
supply. When water reaches the Booster, the swing-check
valve (clapper) will swing open and the monitor will begin to
flow. Clapper position can be verified visually by viewing the
position indicator shown in Figure 5.1.
4. The pump may now be throttled to achieve the desired nozzle
performance. The pressure ratings of the Booster and the
monitor must not be exceeded. To estimate pressure loss
through the Booster (see section 6.0) .
5. When operation is completed, shut off the water supply and
disconnect all hoses. The Side A Inlet of the Booster must be
drained through the upstream device to which it is mounted.
See Section 5.3 on page 19.
NOTICE
To avoid back flow into the water supply, a valve must be closed upstream of the Side A Inlet. The
TFT HUM and IVUM are suitable valves for this purpose.
