IRECTION GB091046, REVISION 2 VIVID E9 / VIVID E7 BT’13 SERVICE MANUAL
7 - 20 Section 7-9 - Troubleshooting
7-9-9 System Temperature Too High
When the temperature inside the VIVID E9 / VIVID E7 increase, the fan speed will increase to cool down
the system. If the air filters become too dusty, a higher fan speed is required to keep the air stream at
the needed level. When the fan speed increase, the fan noise will also increase.
• If the cooling air stream is insufficient to stabilize the interior temperature within the operating
margin, the system will stop operating.
- Solution: Clean or replace the filters.
• If a fan is worn out, it may be noisy, or stop working.
- Solution: Replace the fan(s).
