This document is an installation and operation instruction manual for Coast Air Room Air Conditioners, specifically models CEG-81A and CEG-123A. It provides comprehensive guidance on safe handling, installation, operation, and maintenance of the units.
Function Description:
The Coast Air Room Air Conditioner is designed to provide cooling and, for some models, heating, as well as dehumidification and air circulation for indoor spaces. It aims to maintain a comfortable room temperature and improve air quality. The unit can be controlled either directly via its control panel or remotely using a supplied remote control.
Important Safety Instructions:
The manual emphasizes critical safety precautions to prevent injury, property damage, fire, and electric shock. It categorizes warnings into "WARNING" (possibility of death or serious injury) and "CAUTION" (possibility of injury or property damage).
Key safety points include:
- Electrical Safety:
- Plug in the power plug properly and do not damage or use an unspecified power cord.
- Always install a circuit breaker and a dedicated power circuit.
- Ensure effective grounding to prevent electric shock.
- Do not operate or stop the unit by inserting or pulling out the power plug.
- Unplug the unit if strange sounds, smell, or smoke occur.
- Do not modify power cord length or share the outlet with other appliances.
- If the power cord is damaged, it must be replaced by the manufacturer or an authorized service center.
- Do not use an extension cord or adapter plug.
- The power supply cord contains a current detection device to reduce fire risk. Users are instructed to test this device using the "TEST" and "RESET" buttons on the plug head. If the device fails to reset, the power supply must be replaced.
