1. Safety precautions - This product is an industrial cooling unit for control panel. Do not use this for any other purposes. - Be sure to read these precautions carefully before starting operation for proper use. - All the warnings and cautions described herein must be observed in order to use the product safely. The marks and their meanings shown in this manual are as follows.
2. Mounting 2-1 Caution Danger For prevention of electrical shock, power supply to the control panel should be disconnected before installation work. Caution For installation, do not use any parts other than originally supplied ones. Failure to this may result in injury or breakdown of the cooling unit. In case screws are used for installation instead of the original bolts, put a plate between the screw and the cap nut so as the direct torque not to be transmitted.

2-2 Mounting procedure A. External mounting (1) Process the mounting surface to cut out the openings in accordance with the respective mounting cutout drawings in Page 5. (2) Fit the enclosed bolts to the unit. The number of bolts differs depending on the model. (3) Attach the enclosed packing on the rear side of the unit.

2-3 Attachment of drain hose Moisture arisen from dehumidification by COOLCABI is discharged through a drain hose. Pay attention to the following notices in order to attach the drain hose properly. Caution If the drain hose is not attached properly, water collected in the drain pan inside the COOLCABI may overflow into the control panel interior.
3. Wiring Caution - Please observe all the local regulations in installation of the cooler. - Supply voltage should be as specified on the rating plate. - Allowable power fluctuation is +/- 10% from the rated voltage. Pay attention the maximum fluctuation should be stayed within this range.
3-3 Overcurrent protection Caution Do not forget to fit an earth leakage breaker. → Failure to this may lead to tripping of the earth-leakage breaker for the enclosure in the event of electric leakage. Selection of a breaker should be made so as to fit the type of the cooler. Earth leakage Breaker a.

4-7 Operation mode setting Following to power connetion, COOLCABI starts operation in the each setting mode. Factory setting for the setting temperature is 35℃ with 5℃ differential, which means the compressor starts for cooling when the temperature inside the enclosure reached 35℃and stops at 30℃.Four operation modes of continuous run and three different energy saving mode are available.

(3)Energy-saving mode 2 The internal fan runs in conjunction with cooling operation. Effective for energy saving when cooling operation is stopped under a low temperature like winter season. The values in the ( ) show the default setting. Setting temperature (35℃) Differential temp.
5. Alarm/Safeguard 5-1 Alarm (1) E1:High Temp. Alarm When the internal temperature reaches 45 ℃ (factory setting), the alarm output terminals will break and make contact as set in AS and Ao to light alarm lamp (See the assignment table of alarm output terminals in page 12). The display shows the current internal temperature and E1 by turns to indicate that the internal temperature is too high.
6. Maintenance Caution Be sure to disconnect power before carrying out any maintenance work. Use the specified filter for replacement. Use of fine filters will cause efficiency loss in heat releasing which leads to reduced cooling performance and/or breakdown of the unit. Cleaning and user maintenance shall not be made by children.
