- Fire Alarm & Error Signal Connection: The unit can be integrated with external fire alarm systems and warning devices, providing an output signal (normal open dry contact) when an error occurs.
Maintenance Features:
Regular maintenance is crucial for optimal performance and longevity.
- Filter Change: The unit features a paper pre-filter located inside. To change the filter:
- Detach the CABI LF (cabinet left) panel.
- Replace the filter.
- Reassemble in reverse order.
- Cleaning: After cleaning, the unit should be operated in 'Fan' mode to completely dry the inside.
- Outdoor Fan Grease Injection: Grease should be refilled every 1,000 hours.
- Remove two bolts.
- Inject grease into the port.
- Reassemble the two bolts.
- Troubleshooting: The manual provides a comprehensive troubleshooting guide for common issues such as the unit not working, poor cooling, high pressure, low pressure, sensor errors (AF sensor, TH sensor), compressor issues, fan motor problems, heater overcurrent, water full, fire alarm signals, anti-freezing alarms, reverse phase, and overheat conditions. Each problem is linked to a specific error code displayed on the control panel and includes corrective actions. For example, if the COND filter is blocked or the exhaust duct is kinked, the unit may display an 'E1' error (High pressure), requiring cleaning of the filter and ensuring the duct is clear.
