Troubleshooting Guide

Before you begin consulting the troubleshooting guide, see Figure 8 to ensure the unit is ready for operation. The water level must be between the minimum and maximum water level lines, and the tethered controller must be correctly plugged in (red light on tethered controller will illuminate when cassette is powered on). When turning the unit on, ensure that both the power switch has been turned to the ON ( I ) position and that the standby button has been pressed.

Test Mode
Test Mode has been integrated into this product to improve end-of-line testing during production and can be used to isolate components for individual function testing. Test mode should be conducted by trained personnel only. The icons on the On Board Control buttons (Figure 1) do not match the commands they are associated with, when in test mode.

1. Ensure unit is connected to power and water is supplied.
2. Remove logs or top plate and set aside.
3. Press power switch on (Figure 1A). Presence of power will be indicated by one beep
4. Press the troubleshooting button (Figure 1D) on the side that the testing is required, unit will beep.
5. Press the following buttons to test functionality of listed components – press once will turn On and press again to turn off
6. After 15 seconds of inactivity the unit will beep and then return to regular Standby mode, or the On/Off button can be switched to Off to end the test mode.
