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. Part names and evaporation mechanism 2-1 Part names (example : OCA-S1300BCD-A200) Evaporator Operation (Suction port-inside) panel Internal fan (Cool air output) Suction port Front panel filter - outside (Suction port-outside) Terminal board External fan (inside) Maintenance panel (Exhaust port- outside) 2-2 Evaporation mechanism (example : OCA-S1300BCD-A200) Caution Do not operate the unit without Evaporation Sheet.
3. Mounting 3-1 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.

3-4 Dismounting and relocation Caution In case a cooling unit is dismounted or relocated or the enclosure on which a cooling unit is moved after installation and operation of the cooling unit, eliminate water in the evaporation pan and water pan using a syringe or a wiping cloth.
4. 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. - Make sure that grounding has been properly done.

(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.
6. Alarm/Safeguard 6-1 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 14). The display shows the current internal temperature and E1 by turns to indicate that the internal temperature is too high.

The cooling circuit of COOLCABI has been filled with a required amount of refrigerant, tested for leaks and subject to a trial run before delivery. Therefore, there is no need of maintenance for the circuit. The durability of COOLCABI is generally 30,000 operating hours, provided that its filter is kept clean.
7-3 Replacement of internal fan (Example : OCA-S1300BCD-A200) In the event of a fan failure, go through the following steps to replace the fan. (1) Remove the 4 screws and detach Mounting plate the fan mounting plate. for internal fan (Form of a fan mounting plate differs by model.) (2) Pull out the fan cord and remove the fixing screws and nuts of the fan.
