SECTION 9. BALANCE VALVE INSTALLATION
Install the Piloted Balance Valve (PBV) so it is accessible for adjusting. Ensure that the
water connection is from the discharge side of the pump, and that the valve is correctly
oriented, with the water entering the bottom of the valve.
Note: Waterous will not accept responsibility for the performance of any systems with
an inaccessible PBV.

Figure 27 Piloted Balance Valve inlets and outputs, with push-on hoses
Caution: DO NOT use oil or hose clamps on the Auto-Sync system push-on hoses.
The push-on hose and fittings can be installed more easily if the hose ends are first
soaked in hot water with a small amount of dish soap.
Connect the Auto-Sync system air hoses as shown in the Auto-Sync Air Schematic, and
connect the water line from the discharge side of the fire pump.
Colored hoses are supplied with the compressor kit, long enough for an average
installation, with push-on hose fittings. The schematic is also color coded, which
simplifies the installation. Future service issues are easy to resolve as long as the
colored hose is used as suggested and supplied.
