Model: KCH-03AB

Control Panel Cooler – Non-Freon Model

This is a non-Freon cooler that adopts the new refrigerant R-1234yf.

Features

• This refrigerant is used in common products utilized daily. You can use it with confidence and peace of mind.
• The Ozone Depletion Potential (ODP) is zero. It is an extremely environmentally friendly refrigerant.
• No mandatory management required for various inspections or refrigerant recovery/destruction. Reduces maintenance and disposal costs. (Exempt from the Fluorocarbon Emission Control Law).

Four selectable operating modes.

Features List (Available features vary by model)

Maintenance Notification Function	Refrigerant Pressure Abnormality Alarm	Frost/Freezing Prevention Function
Displays a filter check output signal at set intervals.	If the refrigerant pressure rises due to filter clogging or other issues, the unit stops abnormally and the alarm contact is activated.	Automatically stops to prevent frost growth on the evaporator.
Temperature Sensor Abnormality Alarm	Panel Internal Temperature Abnormality Display	Overload Protection Device
The unit stops and the alarm contact is activated if there is an abnormality in the panel internal temperature sensor or the evaporator temperature sensor.	An abnormality is displayed if the panel internal temperature reaches the set temperature plus 10°C or higher.	If the compressor continues to operate under an overload condition, the protection device automatically stops the compressor.
Energy Saving Mode	Semi-Recessed Mounting Compatibility	Louver Included
Allows setting for energy-saving operation with restricted functionality for the internal fan, external fan, compressor, etc.	Allows for semi-recessed mounting, securing space around the control panel.	Equipped with an accessory louver for adjusting airflow direction at the panel internal discharge port.
