SAFETY INSTALLATION AND MAINTENANCE INSTRUCTION
1.0 GENERAL
1.1 The detailed description of the fan unit supplied is shown on the attached nameplate. All
further information should be checked and if in doubt, contact Fantech Pty Ltd. or the
nearest agent.
1.2 All Fantech equipment must be installed by personnel who are trained in the appropriate
discipline,
1.3 Also, a copy of this document must be available before attempting installation.
1.4 The guards / deflectors supplied with this product comply with AS 4024.1601:2006 & AS
4024.1801:2006.
1.5 It is important that the all Installation and maintenance Instructions are correctly and fully
adhered to.
1.6 Special note: Prior to dispatch all fan units have been inspected and mechanically run.
Due consideration is given to the smooth running of the unit, electrical power input and
rotational speed. Therefore, Fantech Pty Ltd expects that if handled and installed
professionally the goods will give long trouble free service.
1.7 It must also be noted that impulse fans are heavy (~80kg) and must be lifted carefully to
prevent personal injury or damage to equipment
1.8 Ensure that the structure supporting the fan is sufficiently strong to secure the unit. Also
ensure that adequate clearance is available for the air to enter and exit the fan. The fan
must be attached to the supporting structure by anchor bolts suitable for the type of
structure encountered. It is recommended that the holes for the anchor bolts are
predrilled as per the fan footprint (see attached drawing) prior to lifting the fan assembly.
Fantech Pty Ltd does not supply these fixings.
2.0 UPON RECEIPT
2.1 The fan and ancillaries should be visually inspected for any transit damage or loss. This
includes the hand rotation of the impeller within the casing.
2.2 Should any damage, concern or technical queries result from these checks then Fantech
Pty Ltd. or its agent should be contacted stating the fan type, Fantech invoice / contract
number and serial number.
2.3 The electrical supply for the fan unit must be as specified on the fan nameplate subject to
normal supply tolerance and design conditions. Full Load currents are indicated on the
fan nameplate
3.0 STORAGE
3.1 If the fan is not to be used immediately, it should be stored in a clean dry place.
3.2 If the fan is to be subjected to any vibration in its stored location or is going for storage for
longer then one month then Fantech Pty Ltd. or its agent should be consulted for special
instruction in writing.

4.0 START UP
4.1 Once all electrical circuits have been checked with the connection diagram supplied – power
may be supplied to the unit.
4.2 Upon initial start-up, ensure that the fan rotates in the correct direction. Confirm that the
direction of fan discharge and installed location matches any schematic sketches or layouts of
the installation.
4.3 Should it be suspected that the impeller is contacting the casing, the unit should not be run
until a check is made to ensure that an adequate ‘running tip clearance’ exists between the
casing and impeller. Also check that the gap is evenly spaced at various positions in the
casing.
4.4 If the impeller needs centralization within the casing then it must be carried out prior to any
further running.
4.5 A further run of about 30 minutes duration should be made so as to ensure smooth trouble
free operation within the control circuits.
4.6 Once these check runs have been satisfactorily carried out and the equipment is checked to
conform with essential Occupational Health and Safety (OH&S) requirements, then it can be
consider to be adequately installed.
5.0 FAN MAINTENANCE
5.1 Due to the different periods of operation, no rigid inspection and maintenance period can be
recommended. It is suggested therefore that inspection and, if necessary, fan cleaning (by
non abrasive means) is carried out at regular intervals of at most 5,000 running hours or 12
months, whichever comes first.
5.2 All fastenings, of whatever type, should be checked for tightness. The integrity of the rotating
items should be checked
5.3 Bearings are a ‘sealed for life’ type and hence will not need detailed inspection. The motor’s
cleanliness however must be checked, especially in relation to the cooling fan and/or fins, if
fitted.
5.4 If it should be necessary to remove the impeller, then care must be taken and no undue force
used. By removal of the central hub bolt and tab washer the impeller can be removed by
pulling the outside diameter of the hub (Not the blade). Should the impellor fail to detach itself
in this manner, please contact Fantech Pty. Ltd. or its agent for further advice.
