General Installation
CAUTION: Sheet metal parts, screws, clips and similar
items inherently have sharp edges, and it is necessary
that the installer and service personnel exercise cau-
tion.
The installation of this equipment shall be in accordance
with the regulations of authorities having jurisdiction and
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 and build-
ing services.
CAUTION: Disconnect power and lock out power source
before installing or servicing. Failure to disconnect power
can result in electric shock, fire or serious injury.
1. Do not operate the fan beyond the maximum cata-
loged RPM. The current should be verified any time
the RPM is adjusted to ensure it is below the
nameplate amperage value.
2. Verify the equipment is compatible with the power source.
3. Allow motor to cool down before servicing to avoid
injury.
Receiving
When the equipment is received, all items should be
carefully checked against the bill of lading to ensure all
items have been received. Inspect each package for
shipping damage before accepting delivery.
If any damage occurred, notify the carrier, who will make
proper notation on the delivery receipt acknowledging
the damage. Damages should be noted on all copies of
the bill of lading and have all copies countersigned by
the delivering carrier. A Carrier Inspection Report should
be filled out and forwarded to the Traffic Department.
If units are damaged in transit, it is the responsibility of
the receiver to make all claims against the carrier. Twin
City Fan is not responsible for damages incurred during
shipment or after acceptance.
Short Term Storage
If fan installation is to be delayed, store the unit in a
protected area, preferably indoors. Protect fan bearings
and motor from moisture and vibration.
Long Term Storage
Prior to storage, grease fan bearings and motor bearings
per manufacturer's specifications. Note, motors which
contain ball bearings are permanently lubricated as built.
No additional lubrication is required. On belt drive units,
belts should be removed or at least the belt tension
reduced to prevent a sag/set from forming in the fan
shaft and belts. Rotate wheel and shaft monthly and
leave in a different position. When unit is to be removed
from storage and activated, check for corrosion and
damage. All bearing grease should be purged and
replaced with fresh grease.
Unpacking
Verify that all required parts and proper quantities have
been received for each item. Report shortages or miss-
ing items to your local representative to arrange for
replacement parts.
Sometimes it is not possible for all items to ship togeth-
er due to availability of carriers and truck space.
Verification of shipments must be limited to only items
on the bill of lading.
