3. Warnings
Warning!
When this system is used in a life support heating and ventilation system
where failure could result in loss or injury, the user should provide
adequate back-up, or accept the risk of such loss or injury.
Warning!
Wiring and connections must comply with all national and local electrical
codes. Installation by qualified electrician required.
Warning!
Electrical shock may occur if the panel is opened with power connected to
the unit. Before opening the enclosure, make sure that all power sources
to panel, and each stage, are disconnected.
Warning!
The individual stage toggle switches’ “OFF” position will not prevent the
stage from turning on if the back-up system control board senses
temperature above the high limit or below the low limit. For this reason,
the “off” position is not an acceptable electrical isolation for equipment
connected to that stage.
