4.3 Storage prior to assembly
„
Store the individual functional parts in a dry and weatherproof location in their original packaging.
„
Store the functional parts in the temperature range of -20 °C to +40 °C.
„
Cover open pallets with tarpaulins, and protect the functional parts from dirt (e.g. chips, stones, wire, etc.).
„
Frequent and, above all, abrupt temperature changes must be avoided during storage. This is especially harmful if
moisture is able to form condensation.
„
To avoid bearing damage, the fan must be rotated monthly if at a standstill for more than one month.
„
For storage periods of more than 1 year, check the ease of movement of the fans' bearings (by turning by hand)
before assembly.
„
Avoid distorting the housing or other damage during storage.
„
Damage resulting from improper packaging and storage are at the expense of the initiator.
