Fan safety guideline
- We will guarantee the reliability if the application of our products is not exceeded the limitation, which is specified on this specification.
- In case of changes of the specification specified on this document, a written notice is requested in advance.
- Please do not touch the impeller with the pressure and never throw the fan. The bearings inside may be damaged.
- The products would not come with a guarantee if the safety problems or defects are caused by the introduction of powder, droplets of water or insects into the hub. Some special designs are exceptions.
- All the condition mentioned above are typical example and views as the first reference prior to all other information.
- If there is any data or related documentation different from this data sheet this data sheet is the principal reference.
- Please do not use the fan in the environment of corrosive gas or liquid or any detrimental gas.
- Please do not store the fan in the environment of high/low temperature, high humidity or dust. Please do not store or idle the fan in long term;Zaward suggests performance testing is conducted before shipping , if the fans have been stored over 6 months。
- For safety reason, finger guard will be need on the inlet and outlet sides of fan. Do not try to touch or hold the impeller from rotating fan. It could make fan overheat and damage.
- During the installation of the fan, please pay substantial attention to prevent the fan twist, it is possible noise cause by resonance vibration.
- It is very important to notify that use dropped products are not suggestion when in any movement or operation, it will impact the balance of blade. All type fans especially ball bearing type should be avoided to drop down.
- The performance of the products shall be guaranteed by Zaward if the products operate under the parameter defined in the specification.
- Please kindly have an attention that the following application conditions will cause damages,
- The pressure is applied to the impeller
- The fans are lift by dragging the lead wire
- The fans are hard-dropped to the floor
- Zaward fans are not suitable for the environment where is filled with any corrosive fluids.
- Not all fans are provided with the Lock Rotor Protection feature. If you impair the rotation of the impeller for the fans that do not have this function, the performance of those fans will lead to failure.
- Attention to safety is important when testing or using the fans. A suitable fan guard should be fitted to the fan to guard against any potential for personal injury.
- Except of specific statement, all tests are carried out at relative(ambient) temperature and humidity conditions of 25°C, 65%RH. The test value is only for fan performance itself.
- Be certain to connect an “over4.7µF”capacitor to the fan externally when the application calls for using multiple fans in parallel, to avoid any unstable power.
- Positive (+) and Negative (-):
- Connecting the fan to the power source with correct polarity is vital.
- The connection with reverse polarity would cause damages since there is no easy way to prevent such error.
