Product Usage Instructions

Installation:
The Indoor Unit / E2 Type is a high static ducted air conditioning unit designed for exceptional installation flexibility. Follow the steps below to install the unit:

1. Select a suitable location for installation.
2. Ensure the necessary power source is available (220/230/240 V, 1 phase – 50 Hz or 220/230 V, 1 phase – 60 Hz).
3. Connect the required pipe connections for liquid and gas.
4. Install the drain piping.
5. Secure the unit using the provided suspension bolts.
6. Make sure there is sufficient service space around the unit (800mm or more).
7. Mount the optional accessories, if required.

Operation:
To operate the Indoor Unit / E2 Type, follow these steps:

1. Make sure the unit is properly installed and connected to a power source.
2. Use the remote controller (CZ-RTC6W, CZ-RTC6, CZ-RTC5B, CZ-RWS3, or CZ-RWRC3) to control the unit.
3. Select the desired mode (cooling, heating, dry mode, etc.) using the remote controller.
4. Adjust the fan speed and temperature settings as needed.
5. The unit will automatically diagnose any issues and display error codes if necessary.
6. In case of a power outage, the unit will automatically restart with the previous settings once power is restored.

FAQ:

• Q: What are the available static pressure modes for the Indoor Unit / E2 Type?
• A: The available static pressure modes are 270 Pa, 140 Pa, and 60(72*) Pa. You can select between these modes for extra installation flexibility.
• Q: What is the maximum static pressure setting for this unit?
• A: The maximum static pressure setting is 270 Pa. This enables the use of long ducts for installation in a wide range of spaces, making it ideal for large-scale offices, restaurants, and other facilities.
• Q: Does this unit require a Rap Valve Kit?
• A: No, thanks to improved performance, a Rap Valve Kit (CZ-P160RVK2) is no longer required for this unit.
• Q: How much improvement can be expected in sensible cooling?
• A: The new heat exchanger with a 7mm pipe increases the heat transfer surface, resulting in a 5-10% improvement in sensible cooling.
