5.0 Operation
Overrun timer adjustment – models fitted with overrun timers only
Before making any adjustments, isolate the fan from the power supply. Remove
the front cover and the body moulding. Locate the ‘jumper’ on the relevant set
of pins to achieve the desired run-on time (see Fig. 9 & 10).
Humidity adjustment – models fitted with humidistat only
All NA-E humidistat fans automatically sense a rapid change in humidity and
adjust accordingly. The humidity control does not require manual adjustment.
Humidistat fans, when energised for the first time, will run and time out as part
of the stabilising process.
6.0 Maintenance
The fan unit does not require any maintenance. However, for optimum
performance, it is advisable to remove any accumulated dust with a low power
vacuum cleaner.
Note: Installation and maintenance of the equipment must be as directed in
the instructions provided with the unit.
