Installation and operating instructions Wilo-Rexa CUT GI
Installation and electrical connection
▪ Avoid pressure surges!
Pressure surges may arise in long discharge pipes with pronounced route profile. These
pressure surges could lead to pump destruction!
▪ Depending on the operating conditions and the pump chamber size ensure the cooling time
of the motor.
▪ To allow the product to be fixed securely and functionally, the structural components and
foundations must be of sufficient stability. The operator is responsible for the provision and
suitability of the structural components and foundations!
▪ Check that the available consulting documents (installation plans, layout of the operating
space, intake ratios) are complete and correct.
DANGER
Risk of fatal injury due to dangerous lone working practices!
Working in pump chambers and tight spaces as well as working where there is a danger
of falling is dangerous work. This work must not be carried out alone! A second person
must be present for safety reasons.
WARNING
Hand and foot injuries due to a lack of protective equipment!
During work there is a risk of (serious) injury. Wear the following protective equipment:
• Safety gloves that protect against cuts
• Safety shoes
• If lifting equipment is used, a protective helmet must also be worn.
NOTICE
Use only technically faultless lifting equipment!
Use only technically faultless lifting equipment to lift and lower the pump. Make sure
that the pump does not jam during lifting and lowering. Do not exceed the maximum
bearing capacity of the lifting equipment! Check that lifting equipment is functioning
properly before use!
NOTICE
Motor emerging during operation
If the motor emerges during operation, observe the instructions for "non-immersed op-
erating mode"! To ensure the necessary cooling of the motor for continuous duty, the
motor must be completely immersed before re-activation!
▪ Prepare operating space/installation site as follows:
– Clean, cleaned of coarse solids
– Dry well
– Frost-free
– Decontaminated
▪ If toxic or suffocating gases build up, immediately take countermeasures!
▪ For lifting, lowering and transporting the pump use the handle. Never carry or drag the pump
by the power supply cable!
