Understand the Additional Leakage Sensor for Quantum Ultra Ceiling Cassette (CYT-24) SystemsUpdated 10 hours ago

Introduction

This article explains the additional leakage sensor for the Quantum Ultra Ceiling Cassette (CYT-24) systems. 

The auxiliary refrigerant leak sensor monitors the system operation. If refrigerant concentration exceeds the alarm threshold, the system will stop the compressor and start the circulation fan for safety. 

The refrigerant leak sensor is equipped to systems for safety.

Location of the Leakage Sensor

Note: The actual location may vary depending on the model and cabinet design. 

Notes

• Use the additional leakage sensor in only specific installation scenarios that require an auxiliary refrigerant leak sensor to be installed. 
• The refrigerant sensor has a design life of 15 years. Replace the sensor within its service life. 
• The following are the alarm indicators for the refrigerant sensor: 

  Condition	Error Code
  Refrigerant Leak Detected	Display "Hd"
  Communication Error with Refrigerant Sensor	Display "Fd"

• Only use manufacturer-approved sensors as replacements.
