9.1 Deinstallation/installation of the motor
WARNING! Danger of personal injury!
• Touching the pump can cause burns!
Depending on the pump or system operating conditions (fluid temperature),
the entire pump can become very hot.
• At high fluid temperatures and system pressures there is risk of scalding due
to escaping hot fluid.
Before deinstallation of the motor, close the existing check valves on both
sides of the pump, allow the pump to cool to room temperature, and drain the
isolated branch of the system. If no check valves are fitted, drain the whole
system.
• Risk of injury due to the motor falling when the securing screws have been
undone.
Comply with national regulations for accident prevention and also with the
operator's internal works, company and safety regulations. If necessary,
wear protective clothing and equipment!
• During installation/deinstallation of the motor head, the rotor unit can fall
out and injure personnel. Do not hold the motor head with the impeller facing
downward.
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. 1 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.
• The release the motor, undo 4 socket-head screws. Tools that may be required:
• Angled hexagonal recess screwdriver
• Ball-head hexagonal recess screwdriver
• ¼-inch ratchet wrench with appropriate bit
CAUTION! Risk of damage!
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.
