5-2 Safeguard
As a safeguard, this product is designed to stop operation under an abnormal current or
temperature.
In this event, the alarm E1 or E3 will occur. If water level of the drain pan became too
high due to clogging of the primary drain pipe, the float switch provided in the drain
pan terminates cooling for prevention of excessive drain water. In this event, the
alarmE6 will occur. This product has double pipe system to keep enclosure interior from
accidental water entry. Even if the primary drain pipe fails to discharge water due to
pipe clogging, the secondary pipe will compensate it.
When the temperature sensor provided in the heat exchanger on cooling side detects
freezing temperature due to fan failure or other problems, cooling operation stops to
prevent freeze-up of the heat exchanger. In this event, the alarm
E7 will occur
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.
The appliance shall not be cleaned with a water jet.
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. Depending on the environmental condition at the site of use,
check and clean the filter, if used, at least once a week. Clogging on filter may lead to
deterioration in cooling performance, or at worst, may cause shutdown of the unit
due to overloading on the compressor.
6-1 Filter cleaning/replacement
Detach the filter from the guide of the
front panel to clean or replace.
