3 Installation
Read the instructions carefully and pay special attention to the warnings! Always check the pump before operation.
- See pre-use check in section 3.3 Pre-use check - pump without impeller screw.
The large pump sizes are very heavy.
Alfa Laval therefore recommends the use of a lifting crane when handling the pump.
3.2 Installation
Step 1
Always read the technical data thoroughly.
(See chaper 6 Technical data)
Always use a lifting crane when handling the pump.
Always have the pump electrically connected by authorised
personnel. (See the motor instructions).
CAUTION
Alfa Laval cannot be held responsible for incorrect installation.
WARNING:
Alfa Laval recommends the installation of a lockable repair
breaker. If the repair breaker is to be used as an emergency stop,
the colors of the repair breaker must be red and yellow.
Caution:
The pump does not prevent back flow when
intentionally or unintentionally stopped. If back flow
can cause any hazardous situations, precautions
must be taken e.g. check the valve to be installed
in the system preventing hazardous situations from
arising.
Step 2
Ensure at least 0.5 m (1.6 ft) clearance around the pump.
Step 3
Check that the flow direction is correct.
