1. Unplug unit and remove four
screws from bottom housing.
2. Carefully lift top of housing back to
access internal housing.
Your kit includes a diaphragm assembly to return your air pump back to proper
performance. Over time the air pressure and output will drop which typically requires
replacement of the diaphragm. This is considered normal “wear” and can be done on a
regular basis (every 6 to 12 months) or once loss of output is observed.
