Start Up
WARNING
– It is not good for any fan motor, for the user to use the power supply isolator to a fan as a means of day to day control.
This can reduce the life expectancy of the fan motor and may even lead to motor failure unlikely to be covered under our warranty. The
power supply isolator should only be used as a means of isolation of the power supply for maintenance and servicing requirements.
Day to day control should be provided to the user by means of one of the various type of control options as per the wiring diagrams
which follow in this document.
To help protect our fan motors, there is a delayed start function when the mains power is switched off at the isolator. A period of at
least 5 minutes should be allowed between power disconnection and reconnection. If the user is determined to switch the fan on and
off at the power supply isolator then the installer must advise the user of this motor protection function so that they wait the necessary
period of up to 5 minutes between switching on and off.
WARNING
– When switching off mains power for maintenance / servicing, High voltages are present at the terminals and within the
motor for up to 10 minutes after disconnection of the electrical supply.
3.1
Before power is supplied to the unit, check that the wiring is correct as per the fan connection diagram.
3.2
At initial start-up, check that impeller rotation and airflow direction is correct.
