SAFETY CONSIDERATIONS
Hazards may exist within each Fan Module Unit because
it contains electrical and powerful moving components.
Only qualified service personnel should install or service
this equipment. Observe precautions as marked in
literature and on labels attached to each unit.
Main power must be disconnected via the main
disconnect and ‘locked out’ before performing any
service to at each unit(s) – failure to do so could result
in an electric shock which could cause personal injury or
death.
Improper installation, adjustment or alteration to a
unit(s) could cause property damage, personal injury or
death.
During Construction and/or Installation the following
Safety Codes must be observed:
฀Safety Shoes, Safety Glasses, Hard Hats and
Work Gloves must be worn.
฀Fire Extinguishers must be on Site for any
Cutting, Welding and/or Brazing, as required.
INSPECTION on ARRIVAL
All Rosenberg Fan Products are carefully constructed
and inspected prior to shipment to insure the highest
level of quality and performance.
A Visual Inspection of Fan Modules and/or UnoBoxes as
well as optional components should be carried out for
any damage that may have occurred during shipment or
material handling. In addition the Packing List should be
compared to the quantity of items received.
Should any damage be evident or if there is a
discrepancy, with regard to missing items – the Carrier’s
Bill of Lading should be signed indicating damage and
items missing.
INSPECTION prior to INSTALLATION
After all forms of Packaging have been removed from all
the Units, a further inspection of the Fan Wheel in all
cases is required to ensure freedom of rotation and that
there is an equal distance/clearance between the
Wheel Cone and the Inlet Cone through 360o.
If there is a discrepancy in freedom of rotation, the Fan
in question should not be installed and immediately
reported to the Sales Office located in Mississauga,
Ontario.
INSTALLATION of MODULES and UNOBOXES
Prior to installing Modules and/or UnoBoxes, the
supporting structure must be found to be level
horizontally and vertically plum.
Frame Construction with Modules begins with the
installation of the Inlet Cone Plate on to an Engineered
Structure, capable of carrying both static and dynamic
loads, resulting from the operating system. The next
step is to connect the Fan Assembly (Motor Cable
Connectors pointing to floor) with the (4) Struts to the
Inlet Cone Plate. The final assembly of each Module in
the FanGrid requires attaching the Inlet Cone to the
Cone Plate with the Pitot Tube connection pointing
down to the floor.
UnoBox Construction, requires connection angles at
each level, to provide stability at both the Inlet and
Outlet of each UnoBox.
FanGrid , requires that the Design of the Support
Structure, shall be suitable not only for static and
dynamic loads but also have a natural frequency
separation of at least 20% from the Fan System
operating speed/speed ranges.

INSTALLATION of CONSTANT VOLUME CONTROL
SYSTEM
A FANGRID System requires the measurement of
negative Air Pressure within the Space in front of the
Inlet Fans Area. The measurement device consists of ¼”
nylon tubing and 1/8” nylon tees forming a circular
‘Loop’ in the interior of the Space. The distance of the
circular ‘Loop’ from the Inlet Fan Face Area is calculated
by the following
Formula, where (a) and (b) represent the width and
height of the space:
INTERFACE of the CONTROL SYSTEM
The Flow Control of the FANGRID is established by the
connection of the circular ‘Loop’ and the ‘Pitot Ring’ on
each of the Inlet Cones to a DIFFERENTIAL PRESSURE
TRANSDUCER, which converts the Differential Pressure
with Calibration Factor (k-factor) of the Fan System.
ELECTRICAL CONNECTIONS
When installed, the FANGRID and optional Controls
shall be wired and electrically grounded in accordance
with local codes as well as with the National Fire
Protection Association (National Electrical Code),
ANSA/NFPA70 and/or the Canadian Electrical Code CSA
C22.1. The FANGRID installation must have an
uninterrupted, ground to minimize possible personal
injury, should any electrical fault occur. Failure to follow
this procedure could result in that the Installer being
liable for personal injury to others.
Electrical characteristics of each individual Fan in the
FANGRID, specifies maximum voltage and amperage
requirements, for optimum performance.
Required Line Voltage(s) and/or Control Voltage(s) are
detailed and specified in the attached APENDIX A, B, C &
D.
Pre START-UP Check
A – Lock-Out Main Power disconnect to the FANGRID,
prior Module or UnoBox check.
B – On outlet/discharge side check for visible damage
resulting from installation.
C – Check backdraft damper(s) for smooth operation, if
supplied and move dampers to ensure full range of
motion.
D – On inlet side check for damage to inlet cone plate
and inlet cone.
E – Rotate the fan wheel(s) by hand and ensure that
they are properly aligned with inlet cone.
F – Check VFD sizing and ratings for voltage and
horsepower.
G – Check in coming voltage at main disconnect against
phase to phase on three phase electrical system. – if is
not within 5% of Fan Nameplate Rating or 2% of phase
to phase, the condition must be corrected prior to start-
up.

START-UP PROCEEDURE
To ensure proper operation of the FANGRID as per
design, qualified personnel should perform the start-up
as outlined below:
1. Energize incoming main power to the FANGRID.
2. Bump-start the Fan(s) in the FANGRID, to
ensure Fan Rotation is correct – if not check motor
leads, for correct connection.
3. Perform start-up on AC Motor(s) which are VFD
controlled, as specified by the VFD Manufacturer –
adjust the Fan Motor(s) for the correct air volume/Hertz
4. Perform start-up on EC Motors(s) which are (0
to 10 vdc) controlled from Fan Motor.
5. Check if the Constant Volume or Constant Static
Pressure monitoring system is functioning (if supplied)
