Cooling Fan Rotation.
To ensure that the Unit operates at optimum
temperatures, a Cooling Fan is located on the top of
the Unit to draw warm air from the Cabinet
Enclosure. It is imperative that the Fan rotate in the
correct direction.
A label inside the Unit (as
shown at right) indicates the
proper Fan rotation.
‘
E:0090 Phase Sequence
’ Error will appear on the
Controller Screen if the phase sequence is incorrect.
If this occurs, switch the incoming leads ‘L1’ and ‘L3’
to the Unit.
Motor Maintenance Instructions.
Cleaning.
To ensure that the Motor operates at optimum temperatures and provides years of trouble-free service,
periodically clean the outside of the Motor Housing of any build-up of dust, etc. Though it is not anticipated that, if
installed correctly and in a suitable environment, there should be much build-up on the Motor, keeping the
Housing clean will allow the Motor to operate more efficiently.
Lubrication.
This is a ball bearing motor. The bearings have been lubricated at the factory. Motors that do not have regrease
capability are factory lubricated for the normal life of the bearings.
Noted below is a chart outlining the interval at which the Motor should be lubricated, this based on the Motor
horsepower. This must be part of a regular maintenance schedule.
