12. SAFETY
WARNING! Only approved, qualified personnel familiar with the assessment of hazards and risks associated
with fans, and with the use of tools and test equipment required to service such fans, should
install, operate and maintain the product.
CAUTION!
If the installer or user is unable to understand the information in this manual, or has any doubt
that a safe and reliable installation, operation and maintenance of the equipment can be assured,
Woods Air Movement or their representative must be contacted for advice.
WARNING! When fans are retained in storage, access by unauthorised persons must be prevented with the
use of guards, barriers or secure premises such that fan impellers which may be rotating do not
present a hazard.
13. INTRODUCTION & PURPOSE - GENERAL
The Aerofoil Axial Flow Fan is a highly efficient air movement product, designed to operate between a temperature range of
-40°F to +122°F (-4°F on starting). When operating at low temperatures, ice formation on the fan assembly must be prevented.
Some fans may also have a specification which requires them to operate in a high temperature emergency condition
(i.e. Smoke Extract). This capability will be identified on a special label affixed to the fan casing (see also Paragraph 16.4).
Please refer sections 1 to 11 of this document for specific guidance related to our HT Series Smoke venting equipment.
Each fan assembly has been manufactured to specifically to fulfil the requirement of the installation for which it was designed.
No deviation from the original requirement must be implemented without referring to Woods Air Movement USA
(sales.us@flaktgroup.com).
Any queries regarding safety or operating problems must be referred to your local Woods Air Movement office, sales center or
representative, together with full fan/motor nameplate details. Should a fan failure occur whilst the product is under warranty,
then please contact Woods Air Movement USA before any repair work is undertaken.
If speed control is to be provided by means of a frequency converter, then please seek drive selection and compatibility advice
from Woods Air Movement USA or Woods Air Movement UK.
14. STORAGE & HANDLING
WARNING!
While storing fan assemblies, please ensure that access by unauthorized personnel is prevented by using
guards, barriers or secure premises, so that fan impellers, which may be rotating (wind milling), do not present
a hazard.
If the fan assembly is to be stored; check immediately on receipt that it is as ordered and that it has not been damaged in
transit. Where the fan is delivered in a crate (or similar) the crate must be considered as a protective device only.
The crate must not have other equipment stacked on top of it and it must not be stacked on top of other equipment.
The crate structure must not be used as a lifting aid, unless otherwise indicated.
Where a fan is packed inside a crate, a fork-lift truck or similar must be used to transport the product. The fan must be
stored in a safe, clean, dry, vibration free location. If such storage conditions are not available, the motor space heater / anti-
condensation heater (if fitted) should be connected to an appropriate electrical power supply to prevent motor condensation
forming, while the fan should be stored in an appropriate enclosure. Each month, the fan impeller should be given a manual
rapid spin to help prevent grease from hardening and possible bearing brinelling; the impeller must not be in the same angular
position after rotation.
When dismantling the crate to gain access to the fan assembly care must be taken to avoid injury from sharp edges, nails,
staples, splinters, etc. If the fan is to be stored for 12 months or more, then we recommend that the fan is inspected by a
member of the Woods Air Movement service team before commissioning is undertaken.
