The motor frame is held in place by metal stops. Whilst
pulling on the inlet cone, carefully slide the motor frame
forwards and then up to clear the framework.
If required, a large flat head screwdriver may be inserted
between the motor frame and cooler body to gain
additional leverage.
Pull the motor out of the frame and clear of the cooler far
enough to gain access to the motor cable connections at
the back of the motor.
Remove the motor connection cover at the back of the
motor. Disconnect the motor cables (using a small flat
head screwdriver) and remove from the motor frame.
Move the old fan/motor assembly away from the cooler.
WARNING - ELECTRICAL WORK MUST ALWAYS BE
CARRIED OUT BY A QUALIFIED ELECTRICAL
WORKER !
Isolate the Cooler at the switchboard
ensuring that the
circuit breaker or fuse cannot be turned on or re-installed
whilst work is being carried out on the cooler.
Step 1: Air Filter or Safety Grille Removal
Depending upon the options fitted, either the air
filter/cowling assemblies or inlet air safety grille will need
to be removed to allow access the motor front plate. Refer
to the installation, operation and maintenance manual for
instructions.
Before the existing motor can be removed, the excess
length of the motor power and control cables needs to be
fed into the inlet transition.
Remove the small side service door (control box side).
Identify and release the 2x cable glands fitted to the inlet
transition side wall as shown in Fig 1. Push all excess
length of these cables through the glands. There is no
need to remove the cables from the control enclosure.
