,
the fans are mounted directly onto the fan bulkhead.
To remove the fans, ensure the unit is fully isolated and that any moving components have come
to a halt. Remove the side access panels. Separate the connecting fan plug and socket, using the
procedure as detailed on page 10. Carefully remove the double deflection grille from the bottom
of the unit retaining the fixings, and remove the fixings holding the appropriate fan. Remove the
fan through the side access and replace as required. Again ensure all fixings are reinstated, that
the plug and socket are correctly assembled and that loose cables are safely stowed away from
all moving parts.
In order to keep the unit in good order the following maintenance routine is recommended:
The fan impeller should be cleaned every 6 months. Failure to clean the fan on a regular basis could
result in loss of fan performance, or cause it to fall out of balance. If a fan is stationary for long periods
in a humid atmosphere, it should be switched ON for minimum of two hours every month to remove
any moisture that may have condensed within the motor.
The fan motors are maintenance free due to the use of ball bearings with ‘life-long lubrication’.
At the end of the grease life it may be necessary to change the fan unit.
Failure to keep dampers clean could result in the damper becoming inoperative. Clean damper
blades and frames and lubricate with PTFE aerosol or equivalent.
For units with integrated heating, the heating coil should be inspected for debris, dust or dirt build
up. If found contaminated, foreign matter should be removed accordingly; superficial dust or debris
can be removed from the surface of the heat exchange by gently brushing. Loosened debris can then
be vacuumed from the surface of the coil.
When enquiring after or ordering spares contact VES Spares Department, quoting the sales order (SO)
number and unit type as found on the unit nameplate.
