Powering Up / Powering Down
The first powering up must be performed by CANATAL authorized personnel
only. Failure to do so may damage the unit and void the warranty.
The main power switch (rotary disconnect) is located on the front of the unit. Series 6, 8 and
9 only.
Immediately after turning on the main power switch, the control system will perform the
following power up sequence:
1. The control system will generate three short “beep” sound to alert power has been
applied and the unit is about to start.
2. The control system will then perform a self-test and verify all stored setting and data
are within valid range.
3. After the self-test, the control system will count down the programmed “Restart delay”
time and then put the system into normal operation.
To power down unit:
For units in Local Mode log into appropriate security level (refer to Log-in Security). An
On/Off toggle switch will appear on the bottom left corner of the display. Press “O” to power
down unit. Once fan stops, open disconnect.
For units in Timer or Remote Modes, log into security level number three, change On/Off
mode to “Local” (Settings tab, page 2). Follow above procedure to power down unit.
