5.7 HOSE CONNECTION
Make the hose connection(s) to the portable base and extend the hose(s) straight back from the portable base at least 10 feet (3
meters). If only one inlet of a double inlet base be used, a clapper valve will automatically close off the other inlet. Use caution when
turning on the water to the monitor on the portable base. As the hose fills it will become stiff and may cause the monitor and portable
base to slide or tip or both. Open the pumper valve to the monitor slowly.
5.8 PORTABLE BASE STORAGE
The portable base may be stored in a compartment, on the optional storage
bracket, TFT part number XF-B. This bracket is NOT designed to withstand the
reaction forces of an operating monitor stream. It is to be used for storage and
transportation only. The storage bracket may be mounted on a horizontal surface,
horizontally or vertically on a vertical surface, or on the underside of a horizontal
surface such as the top of a compartment. A strap helps hold the base on the
bracket. Mounting instructions are supplied with the bracket.

The optional pressure relief valve on the single inlet portable base can be adjusted
to open between 50 and 200 psi. The pressure relief valve, TFT part A1820, is set at
the factory to open at 150 psi. To change the relief pressure refer to the label on the
bottom side of the pressure relief valve. A pressure relief valve can be added to the
single inlet portable base by removing the cover on the side of the base. For

repaired or replaced immediately. Specific areas to check are as follows:
Truck Mount Base:
1) Sealing surface above swivel joint must be smooth.
2) Swivel joint must rotate freely.
Portable Base:
1) Sealing surface above swivel joint must be smooth.
