Table 4. Start & Run currents etc.
Electrical Details
(See table 3, 4 & 5).
Because the run and start currents depend upon the duty and asso-
ciated ductwork of an individual unit, the values quoted in the
table are nominal.
Run currents will be exceeded if the unit is operated with its cover
removed. It is therefore recommended that the unit is not run for
prolonged periods in this condition.

Testing after Installation
Ensure that the Fan unit and Control and particular control
ancillaries if specified eg PIR, Run/Fail indicators, timeclock etc.
are fitted.
Switch on and check that the fan unit runs satisfactorily.
Using your chosen control, switch over to the standby fan by
means of the control's fan selection switch.
Check that the change-over occurs.
Switch off. If a Run-on Timer is fitted, check that the fan contin-
ues to run.
Time the run-on period, which is adjustable between 5 and 60
minutes nominal.
Timer controls are set at the works to the shortest period.
For speed controls follow the installation set-up procedure
provided with the control.
