Warning
Before attempting to carry out any work on our units, all accompanying documentation
including warning labels on the unit must be referenced.
Should it be necessary to remove any component, ensure that these are resecured into position
once reinstalled. It is critical that after any maintenance work has been conducted that all
components removed/replaced be refitted correctly by a competent engineer.
When accessing the unit ensure the access panels/lids are handled/opened in a controlled
manner so as to avoid damage to the unit or injury to personnel. This is particularly important
with bottom access units.
Care should be taken with larger unit lid removal as this may need to be undertaken by more
than one person.
Caution
Before attempting to carry out any maintenance work, investigative or repair work on our units,
the unit
MUST BE COMPLETELY ISOLATED
from its electrical supply. Ensure a minimum of two
minutes after electrical disconnection before removing access panels. This will allow any moving
parts to come to a rest. When used in conjunction with an Inverter for speed control, a minimum
of
Five minutes
should be given to allow for the capacitors to discharge before starting work.
Care should also be taken when accessing external units as the wind and elements may cause
moving parts to windmill.
Replace the fan assembly onto the fan bulkhead; a small stud has been included to assist with
correct location. When returning the fan assembly to the case take care not to drop the fan
impellor on the inlet eye as incorrect alignment may damage the impellor. Secure the fan plate
with the appropriate fixings, ensuring correct fan aligment with the inlet eye, adjusting as
necessary
25
. A trial spin by hand should indicate if the fan is rubbing. To align, losen the fan
plate fixings, adjust and retighten. It is important that the loom is secured away from the fan
impellor (coil excess cable and zip tie loom to fan plate as appropriate), allow enough slack for
loom connection/removal to fan socket. On reconnection, the plug assembly features a locating
lug to ensure correct orientation. Once rejoined, lock the connection together again using the
locking lever as shown
22
. Carefully replace the lid and ensure all fixings are safely refastened.
