Descriptions:
1. Delta will not guarantee the performance of the products if the application
condition falls outside the parameters set forth in the specification.
2. A written request should be submitted to Delta prior to approval if deviation from
this specification is required.
3. Please exercise caution when handling fans. Damage may be caused when
pressure is applied to the impeller, if the fans are handled by the lead wires, or if
the fans are hard-dropped to the production floor.
4. Except as pertains to some special designs, there is no guarantee that the products
will be free from any such safety problems or failures as caused by the
introduction of powder, droplets of water or encroachment of insect into the hub.
5. The above-mentioned conditions are representative of some unique examples and
viewed as the first point of reference prior to all other information.
6. It is very important to establish the correct polarity before connecting the fan to the
power source. Positive (+) and Negative (-). Damage may be caused to the
fans if connection is with reverse polarity, as there is no foolproof method to
protect against such error.
7. Delta fans are not suitable where any corrosive fluids are introduced to their
environment.
8. Please ensure all fans are stored according to the storage temperature limits
specified. Do not store fans in a high humidity environment. We highly
recommend performance testing is conducted before shipping, if the fans have
been stored over 6 months.
9. 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.
10. Please be cautious when mounting the fan. Incorrect mounting of fans may cause
excess resonance, vibration and subsequent noise.
11. It is important to consider safety when testing the fans. A suitable fan guard should
be fitted to the fan to guard against any potential for personal injury.
12. Except where specifically stated, all tests are carried out at relative (ambient)
temperature and humidity conditions of 25oC, 65%. The test value is only for fan
performance itself.
13. Be certain to connect an “over 4.7µF” capacitor to the fan externally when the
application calls for using multiple fans in parallel, to avoid any unstable power.
