Wear suitable PPE before installation and follow appropriate site safety procedures. Before installation, ensure that all valves are in the closed position. Parker Hi-Pro manifold uses either integral fitting (A-LOK/CPI) or NPT female connections. For connection, please refer to the appropriate installation instruction.
For anti-tamper designs only use the correct key for Parker manifolds. MAINTENANCE Parker Hi-Pro Manifolds are not user-serviceable, except for gland adjustment of the vent needle valve. Gland adjustment becomes necessary when the valve is visibly leaking through the spindle just below the operating handle, or prior to operation when no torque or resistance is evident when operating the valve handle.
