OHM ELECTRIC COOL CABI OCA-H300BC-AW2 Instruction Manual page 35

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.
in case such short circuit is found during operation, take appropriate measures like attaching an
airflow guide plate or an agitation fan. Make sure that the enclosure to which COOLCABI is mounted
is hermetically sealed.
→ Poor airtightness will cause condensation and cooling effect decreases.
Components
In case two or more Condensate-free type COOLCABIs are installed side by side, place a shield plate
and the like between each unit so that the exhaust air from a unit on the left may not be directly
suctioned by the unit on the right.
→ If warm air is inhaled, COOLCABI may not work properly. When cutting out the mounting surface,
put covers on the components inside the enclosure to protect them from cuttng dust.
3- Mounting procedure
Procedures for external mounting of laterally mounted Standard Condensate-free type
Cut out the mounting surface in accordance with the respective mounting cutout drawing.
it the provided fixing bolts to the COOLCABI. The number of bolts differs by model.
3 Affix the provided packing all around the rear side of COOLCABI passing outside of the fixing bolts
See the illustration below .
4 Align the COOLCABI to fit the cutouts.
5 Securely fix the COOLCABI with the washers and nuts on internal side.
6 To ensure airtightness of the enclosure, fill the gaps as necessary.
7 Put the provided "Alarm information label" on a readily visible place.
