AC Series Air Conditioner User Manual

1.1 Product description

This series of products are designed for communication or related industrial equipment applications, serving as high-performance AC type air conditioning units for cabinet internal devices. They are suitable for environments with high heat generation, temperature sensitivity, and require complete isolation between the inside and outside.

Grid application scope: AC 220VAC±15% 50Hz/60Hz.

(Optional other power grid: 220VAC±30%, please contact us.)

For other power supply systems, please refer to the nameplate.

Warning: During transportation, storage, and use, the air conditioner must be kept strictly upright as per the instructions on the package.

3.1 Before Installation

Before installation, prepare the following tools: cross screwdriver, slot type screwdriver, sealing strip, and vice.

3.2 Schematic of Installation

The schematic of installation for Air Conditioner N&L Series is as follows:

Diagram Description: Shows a control cabinet with cut-out dimensions for the air conditioner. Indicates installation gap should be glued. Shows internal and external recycle airflow paths. 'PUSH' indicates the direction to insert the unit.

The schematic of installation for Air Conditioner M Series is as follows:

Diagram Description: Shows three types of installation for M series: Semi-embedded Mounting, Side Mounting, and Door Mounting. Each diagram illustrates the control cabinet, cut-out, installation gap, internal and external recycle airflow, and the 'PUSH' direction.

Attention:

1. N&L series air conditioners do not require a cowling. Customers may add a cowling to M units as they see fit. The cowling can be customer-made.
2. The opening rate for the shield inlet and outlet should be greater than 60% to ensure sufficient circulation air volume, which is crucial for the air conditioner's longevity and reduced service needs.
3. When designing or installing a cowling, ensure that the inlet and outlet air are not short-circuited to maintain optimal cooling performance.

3.3 Air Conditioner Installation

Installation steps:

1. Draw the cabinet mounting cut-out map on the installation surface and cut off the indicated part. Refer to the specification for cut-out maps of different models.
2. Install the air conditioner onto the cabinet following the direction shown in the schematic.
3. If necessary, install the drain pipe on the drain hole.

Double check lists after Installation:

1. Do not use this unit in environments with high oil, burning gas, explosive gas, strong corrosive conditions, ambient air above 55℃, or humidity above 95%.
2. Ensure the product's lean angle does not exceed 3°.
3. Make sure the cabinet is well-sealed to prevent cooling loss and ambient moisture ingress, which could lead to increased condensate water.
4. After installation, ensure the product is upright for 30 minutes before powering it on.

3.4 Electrical Wiring

Before using the air conditioner, connect the electrical wiring according to this manual. It is recommended to use the cables provided in the attachments. If you are unsure about cable specifications, please contact Quick's After-sale Service Department.

Diagram Description: Shows an electrical wiring schematic diagram with terminal labels like RS485, ALARM, I/O, AC POWER, and specific pin functions (T/R+, T/R-, NO, COM, NC). A table lists the terminal instructions with corresponding symbols and definitions (e.g., Positive pole of 485 communication, Normal open port of dry contract alarm output, External signal input port).

4.1 Running

After completing and confirming the wiring, connect the AC power to the air conditioner for its first run. Upon power-on, the air conditioner performs a self-check of the internal fan, temperature sensor, heater, external fan, and compressor.

⚠️ Warning: If abnormal noise or vibration occurs during operation, immediately cut off power and notify a professional for inspection.

4.2 Control Logic

Operational modes: Standby, Cooling, Heating, and Alarming.

Standby mode: If the return air temperature is lower than the default compressor start temperature (e.g., 35℃), the unit enters standby mode. Only the internal fan operates, and the display shows the current return air temperature.

Cooling mode: If the return air temperature is greater than or equal to the default compressor start temperature (e.g., 35℃), the unit enters cooling mode. The external fan starts first, indicated by a symbol. After 60 seconds, the compressor starts, indicated by a bright symbol. The compressor has a minimum running time (default: 5 minutes).

The compressor stops if the return air temperature is less than or equal to the default compressor start temperature minus the stop hysteresis temperature (e.g., 5℃), and the compressor has run for at least the minimum set time. The compressor symbol extinguishes, followed by the external fan symbol.

Heating mode: (Applicable to models with heaters) If the return air temperature is less than or equal to the heater start temperature (e.g., 0℃) minus the stop hysteresis temperature (e.g., 5℃), the heater activates, indicated by a bright symbol. The heater stops if the return air temperature is greater than or equal to the heater start temperature plus the stop hysteresis temperature (e.g., 5℃). The heater symbol extinguishes.

4.3 Instructions of Display Panel

The display panel typically shows the cabinet temperature under normal conditions and alarm codes during malfunctions. The status bar at the bottom indicates different operational statuses via indicator lamps.

Users can check and set various air conditioner parameters via the display panel.

Diagram Description: Illustrates the display panel with a digital readout for temperature or codes, and a status bar with indicator lamps.

Table 4-1: Meanings of lamps on the display panel:

• [Flashing]: Indicates self-diagnose or temperature setting mode.
• [Lamp on when cooling]: Indicates cooling operation.
• [Lamp on when heating]: Indicates heating operation.
• [Lamp on when external fan is running]: Indicates the external fan is operating.
• [Flashing when alarm]: Indicates an alarm condition.

Evaporator temperature query: From the main display, press the [▲] button once to show the evaporator temperature. Press again or the [M] button to return to the main interface.

Condenser temperature query: From the main display, press the [▼] button once to show the condenser temperature. Press again or the [M] button to return to the main interface.

Note: Default parameters are set at the factory. Some parameters may require a password; please contact customer service.

Parameter setting:

Long press the [M] button for 5 seconds to enter parameter setting mode. Use the [▲]/[▼] buttons to select a parameter code. Press [Set] to display the parameter value. Use [▲]/[▼] to adjust the value, then press [Set] to save and return to the code display. Press [M] to exit parameter setting mode. Pressing [M] during value adjustment cancels the change without saving.

4.4 Alarm and Fault

The monitor normally displays the return air temperature. During an alarm, it alternates between displaying the return air temperature and an alarm code. The alarm codes are defined as follows:
