Safety Instructions For Installation And Maintenance Work; Unauthorised Modification And Manufacture Of Spare Parts; Improper Use; Transport And Interim Storage - Resol PSW Basic Manual De Uso

WARNING! Danger due to strong magnetic field!
Inside the machine there is always a strong magnetic field that can cause
injury and damage to property in the event of incorrect dismantling.
• It is only permitted to have the rotor removed from the motor housing by
qualified personnel!
• There is a crushing hazard! When pulling the rotor out of the motor, it may be
suddenly pulled back into its initial position by the strong magnetic field.
• If the unit consisting of impeller, bearing shield and rotor is pulled out of the
motor, persons with medical aids, such as cardiac pacemakers, insulin pumps,
hearing aids, implants or similar are at risk. Death, severe injury and damage to
property may be the result. For such persons, a professional medical assess-
ment is always necessary.
• Electronic devices may be impaired functionally or damaged by the strong
magnetic field of the rotor.
• If the rotor is outside the motor, magnetic objects may be attracted very
suddenly. That can result in injury and damage to property.
In assembled condition, the rotor's magnetic field is guided in the motor's iron
core. There is therefore no harmful magnetic field outside the machine.

Safety instructions for installation and maintenance work

The operator must ensure that all installation and maintenance work is carried
out by authorized and qualified personnel, who are sufficiently informed from their
own detailed study of the operating instructions.
Work to the product/unit must only be carried out when at a standstill. It is man-
datory that the procedure described in the installation and operating instructions
for shutting down the product/unit be complied with.
Immediately on conclusion of the work, all safety and protective devices must be
put back in position and / or re-commissioned.
4.7

Unauthorised modification and manufacture of spare parts

Unauthorised modification and manufacture of spare parts will impair the safety
of the product/personnel and will make void the manufacturer's declarations re-
garding safety.
Modifications to the product are only permissible after consultation with the manu-
facturer. Original spare parts and accessories authorised by the manufacturer ensure
safety. The use of other parts will absolve us of liability for consequential events.

Improper use

The operating safety of the supplied product is only guaranteed for conventional
use in accordance with Section 6 of the operating instructions. The limit values
must on no account fall under or exceed those specified in the catalogue / data
sheet.

Transport and interim storage

Immediately after receiving check the product for damage in transit.
CAUTION! Risk of damage to property!
Incorrect transport and interim storage can cause damage to the product.
The pump must be protected from moisture, frost and mechanical damage due to
impact during transport and interim storage.
Transport conditions
The device must not be exposed to temperatures outside the range of -40 °C up
to +85 °C The transport conditions must be applied max. three months.
Storage conditions
The device must not be exposed to temperatures outside the range 0 °C up to
+40 °C. The storage time can be up to two years. The remaining water, in case of
customer production tests, cannot lead to frost damages.

Intended use

The circulation pumps of the Wilo-Yonos PARA series are designed for hotwater
heating systems and other similar systems with constantly changing volume flows.
Approved fluids are heating water in accordance with VDI 2035, water/glycol mix-
ture at a mixing ratio of max. 1:1. If glycol is added, the delivery data of the pump
must be corrected according to the higher viscosity, depending on the mixing ratio
percentage.
Intended use also includes following these instructions.
Any other use is regarded as incorrect use.
