Storage

If  fans  are  stored  for  any  length  of  time,  they  should 

be stored in a clean, dry location to prevent rust and 

corrosion. Outdoor storage is not recommended. When 

outdoor storage is necessary, fans should be protected 

from the elements as completely as possible. Cover the 

fan inlet and outlet and keep motors dry and clean.
For extended storage (more than 3 months) motor shafts 

and bearings should be rotated monthly. If stored longer 

than 6 months, bearing grease in motor and fan should 

be  purged  and  replaced  with  compatible  grease.  Belts 

should be rechecked for proper tension. Storage records 

should  be  kept  to  assure  proper  maintenance.  The 

factory  can  advise  warranty  centers  to  provide  motor 

and bearing service if needed.

Seller  warrants  to  the  original  purchaser  that  the 

goods  sold  hereunder  shall  be  free  from  defects  in 

workmanship and material under normal use and service 

(except in those cases where the materials are supplied 

by the buyer) for a period of one year from the date of 

original installation or eighteen (18) months from the date 

of shipment, whichever occurs first. The liability of seller 

under this warranty is limited to replacing, repairing, or 

issuing  credit  (at  cost,  F.O.B.  factory  and  at  seller’s 

discretion) for any part or parts which are returned by 

buyer during such period provided that:
a.  Seller  is  notified  in  writing  within  ten  (10)  days 

following  discovery  of  such  defects  by  buyer,  or 

within  ten  (10)  days  after  such  defects  should 

reasonably have been discovered, whichever is less;

b.  The defective unit is returned to seller, transportation 

charges prepaid by buyer;

c.  Payment in full has been received by seller or said

d.  Seller’s examination of such unit shall disclose to its 

satisfaction that such defects have not been caused 

by  misuse,  neglect,  improper  installation,  repair, 

alteration, act of God, or accident.

No  warranty  made  hereunder  shall  extend  to  any 

seller  product  whose  serial  number  is  altered,  effaced 

or  removed.  Seller  makes  no  warranty,  express  or 

implied,  with  respect  to  motors,  switches,  controls, 

or  other  components  of  seller’s  product,  where  such 

components are warranted separately by their respective 

manufacturers. THIS WARRANTY IS EXPRESSLY IN LIEU 

OF ALL OTHER WARRANTIES, EXPRESS OR IMPLIED, 

WHETHER  STATUTORY  OR  OTHERWISE,  INCLUDING 

ANY  IMPLIED  WARRANTY  OF  MERCHANTABILITY  OR 

FITNESS  FOR  A  PARTICULAR  PURPOSE.  In  no  event 

shall  seller  be  liable  to  buyer  for  indirect,  incidental 

collateral,  or  consequential  damages  of  any  kind.

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 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 building services, duct connections.

Sheet  metal  parts,  screws,  clips  and  similar  items 

inherently  have  sharp  edges,  and  it  is  necessary 

that  the  installer  and  service  personnel  excercise 

caution.

CAUTION

The  unit  nameplate  must  be  checked  to  make  sure 

the voltage agrees with the power supply available.
