Installation Requirements

The following list of installation requirements is provided to assure maximum performance of the Toro PVB. Read this list completely prior to installation.

■The installed height of the PVB, when measured at the Critical Level line, must be at least 12" (30.5cm) above the highest downstream water outlet (sprinkler, hose bib etc.). Refer to Figure 1 for location of the Critical Level line.

■Provide an accessible location for periodic inspection and testing of the PVB.

■The PVB must not be subject to standing water which can rise to less than 6" from the Criti- cal Level line.

■Install the PVB vertically with the top of the device in a level position.

■Do not install the PVB in a valve box below ground level.

■Do not install the PVB indoors or in an area where some water spillage is harmful.

■Do not install the PVB until the water supply line has been flushed of foreign material.

■Do not over-tighten inlet and outlet caps – hand-tight is sufficient.

■Do not use the PVB with fertilizer injection.

Caution: Do not allow the PVB to freeze or be subjected to downstream water hammer effect. Thermal water expansion and excessive pressure situations can cause severe damage to the PVB and the irrigation system.

Caution: Use teflon tape for sealing threaded connections. Use of other sealing com- pounds may cause thread deterioration.
