SERVICE & MAINTENANCE
Blower service should be performed by suitably qualified personnel.
If the power supply cord is damaged, it must be replaced by the manufacturer or
it’s service agent.
Ensure the power is switched off and the unit unplugged from the power supply
prior to removing the blower for service to prevent personal injury. Your
Whispair blower has special filters to reduce debris entering the blower and
affecting performance.
Periodically check the Whispair air intake filters and ensure they are clear of
obstructions. Remove and clean the filters if dirty (used compressed air to blow
out debris). Replace filters prior to operation.
WhispairPlus vari-speed & sanitised models
The WhispairPlus has an in-built red LED that communicates several fault conditions.
The LED is located within the left hand air intake (viewed from the pipe connection
end). When lit, the LED can be viewed through the foam filter pad or more brightly
beneath the filter pad.
A solid light indicates worn motor brushes requiring the complete purchase of a new
blower.
A single flash indicates the motor has stopped on over-temperature. The unit can be
restarted when the temperature has been reduced.
A two flash sequence indicates low voltage power supply conditions. The unit can be
restarted only when the power supply is within limits > 200V.
A three flash sequence indicates high voltage power supply conditions. The unit can
be restarted only when the power supply is within limits < 260V.
