Components supplied:
- Complete pump.
- Two-part heat insulation (for single pump only).
- 2 seals (for threaded connections only).
Installation guidelines:
- Installation should only take place once all welding and soldering work has been completed and the pipe network has
been rinsed. Dirt can have an adverse effect on the functioning of the pump.
- The flow direction of the pump must correspond to the directional arrow on the pump housing.
caution
Crash damage. Risk of damage to the O-ring. When turning the motor housing round, ensure the O-ring
-
between the can pot and the pump housing does not become damaged. The O-ring must not be turned and
must remain at the edge of the can pot pointing towards the impeller.
Damage by water. Risk of build-up of condensation water. For units that require insulation and for which the
-
standard insulation provided cannot be used, only the pump housing may be insulated. The condensation water
openings on the motor flange must be left open.
