• When dismantling/installing the motor head, the rotor unit can fall out and
injure personnel. Do not hold the motor head with the impeller facing down-
wards.
The motor does not have to be completely removed from the pump housing if
only the terminal box is to be repositioned. The motor can be rotated to the
desired position whilst still attached to the pump housing (see fig. 2 for the per-
missible installation positions).
CAUTION! Risk of damage to property!
If the motor head is detached from the pump housing for maintenance or
repair work, the O-ring located between the motor head and pump housing
must be replaced with a new one. When installing the motor head, check to
ensure the O-ring is correctly seated.
• To release the motor, undo 4 internal hexagon screws.
CAUTION! Risk of damage to property!
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 the impeller,
and must not be twisted.
• After installation tighten the 4 internal hexagon screws again crosswise.
• To commission the pump refer to chapter 8.
