with a listed suction outlet fitting and one of the four vacuum breaker installation methods on the
following pages.
These MDX instructions provide four design methods to choose from. Your local codes may require additional safety
measures. Paramount Pool & Spa Systems and its representatives cannot recommend or endorse installation
methods other than those provided in these MDX instructions.
NOTICE — Maximum Pump Size:
MDX is rated for a maximum of 90 GPM. While system flow rate will vary with pump size and the Total Head Loss
for a given system, virtually any modern pump is capable of exceeding this limit, therefore it is the responsibility of
the system designer to make sure it is not possible to exceed 90 GPM.
