occur. Immediately remove the original rust preventive coating with petroleum solvent and clean with lint-free cloths.
Polish any remaining rust from surface with crocus cloth or fine emery paper and oil. Do not destroy the continuity
of the surfaces. Wipe clean thoroughly with Tectyl
surfaces or for occasional use, consider using Tectyl
REMOVING FROM STORAGE
As fans are removed 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.
Prior to assembly and installation of the Vektor fan and system components, inspect the fan assembly to make sure
it is in working order.
1. Check all fasteners, set screws on the fan, wheel, bearings, drive, motor base and accessories for tightness.
2. Rotate the fan wheel(s) by hand and assure no parts are rubbing. Access to the wheel is obtained through a
bolted panel located on the side of the fan housing.

General Information

To ensure a successful installation, the instructions in this manual should be read and adhered to. Failure to comply
with proper installation procedures may void the warranty.
Unit and System Identification Tags
Each fan has a permanently affixed manufacturer's engraved metal nameplate containing the model number and
individual serial number.
The tag shown is an example of an identification nameplate on the fan. The
information provides general details about the fan, as well as containing specific
information unique to the unit. When contacting your local manufacturer's
representative with future needs or questions, please have the information on
this label available. Tags are mounted in an area which is clearly visible, usually
on the side of the fan cabinet.
Vektor fan systems may arrive in component pieces due to shipping restrictions. Individual components of a system
have matching identification tags which should be used to identify and assemble the complete system. Assembling
systems with different identification tags can cause reductions in the fan(s) performance.
Prior to fully assembling and installing the Vektor-H or Vektor-HS fans, inspect bypass air plenums and the fan
assembly to make sure they are in working order.

Pre-Installation Information

Before installation, it is important to be certain the mounting surface will bear the operating weight of the unit. For
proper unit operation, it is also important that it be operated in a completely level position.
For further details on safety practices involving industrial and commercial fans, please refer to AMCA
Publication 410.

Electrical Disconnects

All fan motors should have disconnects located in close visual proximity to turn off electrical service. Service
disconnects shall be locked-out when maintenance is being performed.
Moving Parts
All moving parts must have guards to protect personnel. Refer to local codes for requirements as to the number,
type and design. Fully secure fan wheel before performing any maintenance. The fan wheel may start "free wheeling"
even if all electrical power has been disconnected. Before the initial start-up or any restart, check the following items
to make sure that they are installed and secure.
• Do not spin fan wheel faster than the maximum cataloged fan rpm.
• Adjustments to fan speed significantly affects motor load. If the fan RPM is changed, the motor current should be
checked to make sure it is not exceeding the motor nameplate amps.
Guards (Motor Cover, Weatherhoods)
Do not operate fans without proper protective devices in place. Failure to do so may result in serious bodily injury
and property damage. Check local codes to ensure compliance for all protective devices.
Air Pressure and Suction
In addition to the usual hazards associated with rotating machinery, fans also create a dangerous suction at the inlet.
Special caution needs to be used when moving around a fan, whether it is in operation or not. Before start-up, make
sure the inlet area is clear of personnel and loose objects.
