When filling from a hydrant, use the lay-flat hoses stored in the OSM Locker and the Standpipe in
the OSR Locker.
Filling the tank from a hydrant:
1.
Position the appliance in range of the hydrant.
2.
Retrieve the standpipe, the standpipe pry bar, a QRT Spanner and the 64mm lay-flat hose
from their storage locations in the OSM Locker.
3.
Connect the standpipe to the fire hydrant.
4.
Ensure the outlet is pointing safely away from the appliance and personnel, then briefly
open and close the standpipe to flush any contaminants.
5.
Connect the lay-flat hose to the Hydrant Fill Point and the Stand Pipe and, using the
appropriate tools, ensure the couplings are tight.
6.
Open the Hydrant Fill Valve (appliance side).
7.
Open the Standpipe Valve. Water will fill the lay-flat hose and will start to fill the tank.
8.
Monitor the water level via the sight tube on the rear face of the tank.
9.
When the float in the sight tube reaches the top, the tank is full. Shut off the Standpipe
Valve.
10.
Shut off the Hydrant Fill Valve on the Hydrant Fill Point (on the appliance).
11.
Disconnect the lay-flat hose from the appliance and the standpipe and drain.
12.
Place the cap back on the Hydrant Fill Point on the appliance.
13.
Remove the Standpipe from the fire hydrant and return it to its storage location.
14.
Roll up the hose and return the hose to its storage location.
15.
Return the standpipe key and any other tools or fittings to their storage location.
13.3.5 Water Delivery
There are three options for water discharge on this appliance:
2 x 64mm QRT outlets (Delivery 1 and Delivery 2), on the Discharge Manifold.
Hose Reel on the NS or OS.
Handline Outlets on the NS or OS.
To discharge water from the manifold Delivery Outlets:
1.
Select which discharge outlet to use Delivery 1 or Delivery 2.
2.
Remove the relevant lay-flat hoses from their storage location.
3.
Roll out hoses and connect them to the relevant outlet.
4.
Ensure the other end of the hose is coupled correctly to the destination receptacle or
branch.
5.
Select Water Source, i.e. Tank or Inlet Suction (refer to section 13.3.1 Page 61).
6.
Start the pump set as per instructions in section 13.2.6 (Page 59).
7.
Once the pump has started and is up to pressure, open the ball valve for the relevant
discharge outlet to discharge water into the lay-flat hose.
NOTE
To avoid water wastage, carefully monitor the onboard tank being filled. Reduce the water flow
when the water level float nears the top. Shut off the fire hydrant once the tank is full.
