3. Mounting 3- Precautions for mounting Danger or prevention of electrical shock, power connection to the enclosure should be disconnected before starting installation work. Electrical works required for installation of the cooling unit should be done only by specialists. Installation of the cooling unit should be done only by persons with specialized knowledge. Caution or installation, do not use any parts other than originally supplied ones.

Caution About Short circuit Electric components or other objects located near the cool air outlet may disturb cool air circulation. If cool air blown out from COOLCABI hits against them, it can directly return to the suction port without being distributed to the whole area in the enclosure, which is called short circuit of air. This causes not only troubles of the components but put an extra load on cooling operation which results in overcurrent and product failure.

Caution Nut for attaching eyebolt wo nuts are provided on top of COOLCABI for attaching eyebolts. When lifting up a COOLCABI using eyebolts, be sure to use both of these nuts to equalize the load. Lifting up one side only can lead to failure, fall or breakage of the COOLCABI. ●Mounting cutouts for external mounting –...
4. Wiring Caution Please observe all the related regulations of your country in installing and wiring COOLCABI. Supply voltage should be as specified on the rating plate. Allowable power fluctuation in operation is between +5% and - % of the rated voltage. It means only instantaneous voltage fluctuation is allowed and does not mean that any voltage within this range can be constantly supplied.
5. Operation Precautions for operation Caution or protection of compressor, wait at least 3 minutes after installation and then turn power on to start operation. requent turning on and off of a compressor may be a cause of product failure and shorten its lifetime.

5-3 Change of Setting temperature Caution It is basically recommended to maintain the initial set value of 35℃. Setting at an unnecessarily low value may cause excessive condensation and excess amount of drainage water. Turn on the COOLCABI. The current internal temperature is displayed. Press the SET button.

5-6 Operation mode setting ollowing to power connection, COOLCABI starts operation in each operation mode. actory setting for the setting temperature is 35℃ with 5℃ differential, which means the compressor starts for cooling when the temperature inside an enclosure reaches 35℃ and stops at 3 ℃. Two operation modes of continuous run and energy saving operation are available.
6. Alarm Alarm number COOLCABI outputs alarm when it detects an abnormality. An alarm number is displayed, the alarm lamp lights up and alarm contacts change over by the setting of alarm output terminals. Operation Alarm No. Description Cause Remedy behavior ilter clogging Eliminate the cause of problem.

Assignment of alarm output terminals Once an alarm is detected, the alarm output contact changes over. By setting the alarm output terminals, monitoring of many different operations is enabled. Each setting functions by ☞ changing the parameters AS and Ao See page 3 .
7. Maintenance Caution Be sure to disconnect power before carrying out any maintenance work. Carry out maintenance works properly by designated personnel who has specialized knowledge. Before starting any maintenance work, check for a refrigerant leak using a safe detector which does not use fire.

7-3 Replacement of Internal fan Replacement procedures for internal fan is as follows. Turn off the COOLCABI. 1) Loosen the screws to detach the fan mounting plate. Position of fan mounting plate is different by model 2) all-prevention screws are used for Roof mounting type. Remove the 4 fixing screws from the fan.
8. Communication function Serial communication using the communication terminal enables to change the settings and acquire data of operating state and alarm history. 8- Preparation for communication Connect the communication cable with the communication terminal. Use a shielded communication cable and connect its shield to the terminal.
