emery paper and oil. Do not destroy the continuity of the
surfaces. Wipe clean thoroughly with Tectyl
® 506 (Ashland
Inc.) or the equivalent. For hard to reach internal surfaces
or for occasional use, consider using Tectyl
® 511M Rust
Preventive or WD-40 ® or the equivalent.
Removing from Storage
As fans are moved from storage to be installed in their
final location, they should be protected and maintained
in a similar fashion until the fan equipment goes into
operation. Purge grease before putting fan into service.
Installation
Service Access - Greenheck recommends all vane axial
installations be provided
with a means for service
access. This access may
be in the form of access
doors in the duct system,
removable duct sections,
inlet and outlet cones or
an optional inspection
section (Fig. 2).
Service access is necessary to inspect and repair
internal fan components, both at the inlet and outlet
ends of the fan. Fans installed without consideration
for service access can result in time consuming and
expensive removal of connected ductwork.
Airflow Direction - Airflow through a vane axial fan
enters at the impeller end and is exhausted out the end
of the fan containing the motor (direct drive) or drive
components (belt drive). Additionally, an arrow decal is
affixed to the fan indicating direction of airflow.

Electrical Connection
Electrical connections are made to wires located in
the junction box located on the fan housing for direct
drive fans or in the junction box located on the motor
for belt drive fans. The electrical supply must be
compatible with the motor with regard to voltage, phase
and amperage capacity. The electrical supply must be
provided with a lockable disconnect switch, proper
fusing and comply with local and national electric
codes.
Greenheck recommends a vibration switch be installed
in the electrical circuit to disable the fan in event of
abnormal vibration. These switches are available
through your nearest Greenheck representative.
