Before fitting this unloader please study and action this VIDEO of an important safety step.

Please see the image with the 'arrows' and follow these instructions:

• A. These ports are the bypass ports and at least one must never be blocked or closed.
• B. These are the inlet ports – the one not used must be blanked off.
• C. This is the outlet port.
• D. This is the pressure regulating wheel - BEFORE powering the system the unloader valve MUST be set at MINIMUM pressure. Then set the unloader to the required pressure (which MUST be LESS than the maximum unloader pressure of the unloader valve AND LESS than the maximum pressure of your equipment); 4. Set the locking nuts so this pressure (the running pressure and the lock line pressure) cannot be exceeded.
