can disconnect the unit by:
• Switch the isolator to the 'OFF' position for the outdoor equipment (if applicable)

9.3 Alarms and error messages
Details and explanation of the alarms by Multi-DENCO units are available in controller
manual.
Chapter 11 'Fault Finding and Troubleshooting' has details of typical issues than can
be encountered.
Multi-DENCO units use fans which are regulated independently by the main control
board. Removing guards whilst unit is operational risks death or serious injury.
Inverters also store energy for a period of time after isolation.
• Disable the unit.
• Electrically isolate the unit.
• Wait AT LEAST 5 minutes.
9 Once fan momentum has ceased and the inverter energy discharged, you can
open the doors and conduct work.

When the isolator fitted to the unit (or within 1 m) is in the OFF position, the first half
of the isolator could still be live (with electrical power).
• To ensure safe operations, ensure that the circuit has been isolated in the OFF
position at the mains distribution board and suitably locked to prevent inadvertent
re-connection of electrical power.
NOTICE
Resetting of alarms without rectifying the cause can lead to extended unit damage,
which may result in the voiding of the warranty.
