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.
Table of Contents
Unit Identification
System Identification Tags
The tag shown is an example of an identification
label on the fan. The information provides general
details about the fan, as well as containing specific
information unique to the unit. When contacting
your Greenheck 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.
ERS and 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.
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.
Pre-Installation Checks
Prior to fully assembling and installing the ERS plenum
cabinet and Vektor fan bypass plenum components,
inspect plenums, coils, and fan assembly to make
sure they are in working order.
Storage
When an ERS plenum cabinet is not going to be
in service for an extended period of time, certain
procedures should be followed to keep the plenum
and coils in proper operating condition. Cover unit
with tarp to protect from dirt and moisture.
