General Instructions
(In-line Fan)
CFT-CPF-CCK-CPA Series
IGB017.E1/0703
This manual is to assist the engineer to avoid the most common fan problems caused by improper
storage, installation, operation and maintenance. HANDLING AND MAINTENANCE SHOULD
ALWAYS BE PERFORMED BY EXPERIENCED AND TRAINED PERSONNEL.
RECEIVING, HANDLING AND STORAGE
Rough handling during shipment and improper storage can cause damage that is not noticeable until the
fan is in operation. This can be avoided with proper storage and handling techniques.
Touch up the scratch coated surfaces during lifting, to prevent corrosion to occur at this area. Store the
fan in a clean and dry place, preferably indoor to ensure fan shaft, bearing and fan casing are protected
against dust and corrosion. Do not store the fan in a location where it will be subjected to high vibration.
This can cause the internal surface to rub against each other and damage the bearings.
START-UP CHECK LIST
Before putting any fan into initial operation the manufacturer’s instruction must be followed. Complete
the following checklist to make sure that the fan is ready to run.
•Lock out the primary and all secondary power sources.
•Make sure the foundation or mounting arrangement and the duct
connections are adequately designed in accordance with recognized
acceptable engineering practices.
•Check and tighten all hold-down (securing) bolts.
•Spin impeller to see whether it rotates freely and is not grossly out of balance.
•Inspect impeller for correct rotation for the fan design.
•Check belt drive alignment, use recommended belt tension.
•Check belt drive for proper sheave selection and make sure they are not
reversed.
•Properly secure all safety guards.
•Switch on the electrical supply and allow the fan to reach full speed.
Check carefully for :- (1) Excessive vibration
(2) Unusual noise
(3) Proper amperage and voltage values
(4) Proper belt alignment
If any problem is indicated, SWITCH OFF IMMEDIATELY. Lock out the
electrical supply, secure the fan impeller if there is a potential for wind
milling. (impeller turning due to a draft through the system).
Check carefully the cause and correct as required.
The fan may now be put into operation but during the first 8 hrs of running, it should be
periodically observed and checked for excessive vibration and noise. Check the motor input
current and motor temperature to ensure that they do not exceed manufacturer’s
recommendation. After 8 hrs of operation, the fan should be shut down to check for the
following items: (1) All set screws and hold-down bolts
(2) Belt drive alignment
(3) Belt drive tension
(4) Bearing housing temperature
* For V-belt drive installation and belt tension, please refer to our general installation guide for
Centrifugal Fan (IGB016.0/0600) for more information.
Installation Method
ROUTINE MAINTENANCE
Maintenance should always be performed by experienced and trained personnel. Do not attempt any
maintenance on a fan unless the electrical supply has been locked out or tagged out and the impeller has
been secured.
Under normal circumstances, handling clean air, the system should require cleaning only about a Year.
However, the fan and system should be checked at regular intervals to detect any unusual accumulation.
The fan impeller sh.ould be specially checked for build-up of material or dirt which may cause an
Imbalance with resulting undue wear on bearings and belt drives. A regular maintenance program Should
be established as needed to prevent material build-up.
Periodic inspection of the rotating assembly must be made to detect any indication of weakening of the
rotor because of corrosion, erosion, or metal fatigue.
