Espa NOX - Maintenance; Disposing of the Product

EN
The power supply socket for the apparatus must be
at least 3.5m from the pool.
6. DISPOSING OF THE PRODUCT
When the pump is eventually disposed of, please
note that it contains no toxic or polluting material.
All main components are material identified to allow
selective disposal.
Single-phase motors have thermal protec-
tion.
All of three phase motor pumps do not
incorporate this protection. They must be
This product or parts of it must be disposed of in an
environmentally sound way, use the waste
collection service. If this is not possible, contact the

breaker that can be adjusted manually. Set
the circuit breaker according to the current
given in the rating plate plus 10%.

Follow instructions given on fig.1 for correct
electrical connection.
3.5. Pre-start checks
Ensure the voltage and frequency of the
supply corresponds to the values indicated
on the electrical data label.
Ensure that the pump shaft is rotating freely.
Fill the pump body with water through the filter
cover to the bottom level of the suction line.
Check all joints and connections for leaks.
Set the prefilter cover back in place and screw it to

Connect power supply. There will be a delay before
water appears at the end of the discharge pipe.
Viewings from the fan ensure that the rotation of the
motor is clockwise. On three phase pumps the
motor may rotate anticlockwise. If this is happening,
the flow will be lower than expected. To rectify this
situation the two supply phases need to be re-
versed.

5. MAINTENANCE
Under normal conditions these pumps require no
special or planned maintenance.
Clean the pump with a damp cloth without using
harsh products.
If the pump is not to be operated for a long
period it is recommended to remove it from
the installation, drain down and store in a dry,
well ventilated place.
