Installation and operating instructions Wilo-Rexa CUT GE 15
▪Place the pump upright (vertical) on a firm bearing surface and secure it against slip-
ping and falling over!
▪The max. storage temperature is -15°C to +60°C (5°F to 140°F) at a max. relative hu-
midity of 90%, non-condensing. Frost-proof storage at a temperature of 5°C to 25°C
(41°F to 77°F) with relative humidity of 40% to 50% is recommended.
▪Do not store the pump in rooms in which welding work is carried out. The resulting
gases or radiation can corrode the elastomer parts and coatings.
▪Seal the suction and pressure connection tightly.
▪Protect power supply cables against kinking and damage.
▪Protect the pump from direct sunlight and heat. Extreme heat can cause damage to the
impellers and the coating!
▪Elastomer parts and the coating are subject to natural brittleness. Contact customer
service if the pump must be stored for more than 6months.
After storage, remove any dust and oil from the pump and check the coating for dam-
age. Repair damaged coatings before further use.
6 Installation and electrical con-
nection
6.1 Personnel qualifications

▪Horizontal installation
6.3 Operator responsibilities
▪Observe locally applicable accident prevention and safety regulations of trade associ-
ations.
▪Observe all regulations for working with heavy loads and under suspended loads.
▪Provide protective equipment and ensure that the protective equipment is worn by
personnel.
▪Observe local sewage technology regulations for the operation of sewage systems.
▪Avoid pressure surges!
Pressure surges can occur in long pressure pipes with steep terrain. These pressure
surges can lead to the destruction of the pump!
▪Ensure the cooling time of the motor depending on the operating conditions and the
size of the pump chamber.
▪Structural components and foundations must be of sufficient stability in order to allow
the device to be fixed securely and functionally. The operator is responsible for the pro-
vision and suitability of the structural component/foundation!
▪Check that the available consulting documents (installation plans, design of the operat-
ing space, inflow conditions) are complete and correct.
