Receiving, Inspection & Unpacking
Installation
When the equipment is received all items should be carefully checked against the bill of lading to be sure all crates
and cartons have been received. Before accepting delivery, carefully inspect each carton or crate for visible shipping
damage. If any damage is noticed, the carrier should make the proper notation on the delivery receipt acknowledging
the damage. Make notations of all damage on all copies of the bill of lading and have all copies countersigned by
the delivering carrier. The carrier should also fill out a Carrier Inspection Report. The factory Traffic Department should
then be contacted. File claim for damage with the carrier. Physical damage to the unit after acceptance is not the
responsibility of Twin City Fan Companies, Ltd.
Unpack each carton or crate and verify that all required parts and proper quantities of each item have been received.
Refer to drawings for part descriptions. Report shortages or missing items to your local representative to arrange for
replacement parts.
Due to availability of carriers and truck space, it is not possible to guarantee that all items will be shipped together.
Verification of shipments must be limited to only those items on the bill of lading.
The unit nameplate must be checked to make sure the voltage agrees with the power supply available.
CAUTION: Sheet metal parts, screws, clips and similar
items inherently have sharp edges, and it is necessary
that the installer and service personnel exercise
caution.
The installation of this equipment shall be in accordance
with the regulations of authorities having jurisdiction and
with all applicable codes.
This equipment is to be installed by an experienced
installation company and fully trained personnel.
The mechanical installation of the exhaust ventilator
consists of making final connections between the unit,
building services, and duct connections.
1. Before setting unit on curb (if damper is to be used),
make sure that the damper is installed correctly and
that it is operative. See diagram, page 6.
2. Position unit on roof curb so that the wiring can be
run through one of the knockouts provided. Wiring to
the unit may be run through knockouts provided in
the curb cap or the side of the unit. Provide enough
slack in the wiring to the unit to allow lifting, and
removal for cleaning, and inspection.
3. Connect supply leads to the disconnect switch.

attached instruction cards.

subject to misalignment in shipping or installation.

tional label in motor compartment.
7. Lag bolt the unit to the roof curb using a minimum
of four bolts, one at each corner. Replace unit top
