Step 1 — Installation Position

Install the dampener in-line, as close as possible to and before the device causing the water hammer pressure

spike (see FIGURE 2). For example, if a quick closing valve is causing water hammer, install the dampener on a

tee or elbow as close as possible upstream of the valve. Dampener installation should be no more than ten pipe

diameters from the valve. It is advisable to install an isolation valve between the dampener inlet and the

mounting tee so maintenance and pressure checks can be done while the system is operating.

Step 2 — Charging and Start-Up (see Pre-Charge Notes)

Chargeable models do not require an air line connection. Dampener can be pre-charged with compressed air up

to a maximum pressure of 150 psi (10.3 bar). If maximum pressure will exceed 150 psi (10.3 bar), dampener must

be pre-charged with Nitrogen only. Use a hand pump, Nitrogen tank or air compressor to charge dampener. DO

NOT USE OXYGEN. Charging hose kits are available from BLACOH.

The dampener must be pre-charged after installation but prior to system operation. The only method to get an

accurate pressure charge in the dampener is to charge it prior to system start up or with a closed isolation valve at

the dampener inlet. Pre-charge the dampener with 90% to 95% of expected system pressure. DO NOT USE

OXYGEN. A fill valve similar to a Schrader type tire valve but designed for suppressors, is mounted to the top of

the dampener. Replace fill valve cap after charging dampener and re-check dampener charge every month.
