desired position whilst still attached to the pump housing (see Fig. 2 for the per-
missible installation positions).
CAUTION! Risk of damage!
If for maintenance or repair work the motor head is detached from the pump
housing, the O-ring located between the motor head and pump housing must
be replaced with a new one. When installing the motor head, check that the
O-ring is correctly seated.

• Angled hexagonal recess screwdriver
• Ball-head hexagonal recess screwdriver
• ¼-inch ratchet wrench with appropriate bit

Do not damage the O-ring located between the motor head and the pump
housing. The O-ring must lie in the angled end shield that faces towards the
impeller, and must not be twisted.
• After the installation tighten the 4 socket-head screws again, working across
diagonals.
