CLIveT D140 4 Way Cassette Instruction Manual

The indoor unit is available in various models with different
cooling and heating capacities, power supplies, and technical
specifications. Below are the general technical data for each
model:

Model	Cooling Capacity (kW)	Heating Capacity (kW)	Power Supply	Fan Motor Type	Air Flow Rate (m3/h)	Sound Pressure Level (dB)
Q4DN-3-XY D28	2.8	3.2	1-phase, 220-240V, 50Hz	DC motor	790	30

Installation Instructions

1. Ensure the power supply matches the unit requirements.

2. Connect the liquid and gas pipes according to the specified
sizes.

3. Install the drain pipe properly to avoid leakage.

Maintenance and Cleaning

1. Regularly clean the indoor coil and fan motor to maintain
optimal performance.

2. Check for any refrigerant leaks and consult a professional if
needed.

FAQ

Q: What should I do if the unit is not cooling/heating
properly?

A: Check if the filters are clean and ensure proper airflow. If
the issue persists, contact a certified technician for
inspection.

Q: Can I use a different refrigerant than R-410A?

A: It is recommended to use the specified refrigerant to
maintain product efficiency and performance.

Unit Placement
Placement Considerations Unit placement should take account of the following considerations: · Units should not be installed in the following locations:
· A place filled with mineral oil, fumes or mist, like a kitchen. · A place where there are corrosive gases, such as acid or alkaline gases. · A place exposed to combustible gases and using volatile combustible gases such as diluent or gasoline. · A place where there is equipment emitting electromagnetic radiation. · A place where there is a high salt content in the air like a coast. · Do not use the air conditioner in an environment where an explosion may occur. · Places like in vehicles or cabin rooms. · Factories with major voltage fluctuations in the power supplies. · Other special environmental conditions. · Units should be installed in positions where: · Ensure that the airflow in and out of the IDU is reasonably organized to form an air circulation in the room. · Ensure IDU maintenance space. · The nearer the drainage pipe and copper pipe are to the ODU, the lower the pipe cost is. · Prevent the air conditioner from blowing directly to the human body. · The closer the wiring to the power cabinet, the lower the wiring cost is. · Keep the air-conditioning return air away from the setting sun of the room. · Be careful not to interfere with the light tank, fire pipe, gas pipe and other facilities. · The IDU should not be lifted in the places like load-bearing beam and columns that affect the structural safety of the house. · The wired controller and the IDU should be in the same installation space; otherwise, the sampling point setting of the wired con-
troller need to be changed.
Space Requirements
1. The centerline of the maintenance hole should be in the same position as the centerline of the indoor unit. 2. The dimensions of A are shown in Table 2,1

Notes for installers and service engineers
Caution · All installation , servicing and maintenance must be carried out by competent and suitably qualified, certified and accredited profes-
sionals and in accordance with all applicable legislation. · Units should be grounded in accordance with all applicable legislation . Metal and other conductive components should be insula-
ted in accordance with all applicable legislation. · Power supply wiring should be securely fastened at the power supply terminals – loose power supply wiring would represent a fire
risk. · After installation, servicing or maintenance, the electric control box cover should be closed. Failing to close the electric control box
cover risks fire or electric shock. · The dotted lines indicate the field wiring or optional function · D1D2 communication ports are used for group control communication. When connecting the group controller, the D1D2 port of the
indoor units that are to be group controlled must be connected in daisy chain, and the group controller must be connected to the X1X2 port of one of the indoor units in the group control, and set to group control mode. In addition, D1D2 communication ports can also be connected to the central controller.
