necessary to carry out the following operations:

1. The diameter of the suction and lines should correspond to
the diameter of the connections of the pump housing (1”).
See fi gure 2. For a suction height of over 12 ft., a suction
hose with a greater diameter should be used.

2. Fit the suction lines with the foot valve to the pump (at
point 1, Fig 2), avoiding siphons, counter slopes and stand
the pump on solid, fl at level ground.

switch should be run from the meter or breaker box and
properly grounded.

6. Open all shut-off devices in the pressure system of the
pump (e.g.) DEF nozzle, so that air can escape during the
priming operation

7. The temperature of the DEF must never exceed 35° C or
100° F.

8. Always unplug the pump before working on it, in case of
maintenance.
