Dampener can be installed vertically on a tee in the system piping. Vertical installation requires a cap be installed on the top
end of dampener. This type of installation, referred to as appendage installation, will cause product holdup and cannot be
used for mechanical (CIP) applications. If a flexible connector is used in the piping system, attach dampener to the pump’s
discharge outlet and connect the flexible connector to the downstream end of dampener.

Chargeable Model
Read Before Installation
Charging and Start-Up (see Charge Notes)
Chargeable models do not require an air line connection. Dampener should be pre-charged with 3A standard approved
compressed air or clean dry Nitrogen. Use a hand pump, Nitrogen tank or air compressor to charge dampener.
DO NOT
USE OXYGEN.
Charging hose kits are available from BLACOH.
Prior to starting the pump
, pre-charge the dampener to approximately
30%
of expected system pressure and replace fill
valve cap.
DO NOT USE OXYGEN.
The pre-charge pressure in the dampener must always be lower than pump discharge
pressure. Start the pump to generate system pressure. The dampener charge pressure may need to be adjusted up or down
to be most effective in reducing pulsation.
NOTE:
The most effective method to set the proper dampener charge is to install
a glycerin-filled pressure gauge downstream of the dampener and adjust the dampener to minimize needle movement on the
gauge.
Once system pressure is in contact with the bladder, the gas charge will be compressed to the system pressure and
the dampener gauge will read the system pressure, not the initial charge pressure.
Once working pressure is
achieved, adjustment may be necessary. Gradually increase or decrease the gas charge in the dampener by bleeding or
filling through the gas valve. Allow the system to respond to each adjustment (this may take a minute or two) before making
further adjustments.
NOTE:
It is important to replace the charge valve cap tightly after charging because pressure can be
slowly lost through a valve without a cap.
