Table 7-3 Contents of monthly check
Ventilating condition
(air cooled type)
Clean the ventilating
grilles.
Make sure the ventilating grilles are not clogged
with dust, etc.
Facility water
(water cooled type)
Check the facility water.
Make sure the facility water is clean and contains
no foreign matter.
◼ Cleaning of air ventilation port (Air cooled type.)
Clean the dust-proof filters with a long bristled brush or by air blow to prevent
the fins from being deformed or damaged.
◼ Removal of the dust-proof filter
1. The dust-proof filters are installed on the front and left sides of the product.
The dust-proof filters are mounted at four sections. They are all identical in shape.
2. They can be removed as shown in the drawing below.
Care should be taken not to deform or scratch the air cooled condenser (fins) while removing
the filters.
Fig. 7-1: Removal of the dust-proof filter
If the fins of the air-cooled condenser become clogged with dust or
debris, heat radiation performance declines. This will result in the
reduction of cooling performance, and may stop the operation
because the safety device is triggered.
