Make the inspection opening at the specific place on the ceiling so the constant cleaning or the equipment checking
of filter and heat exchange element can be performed.
• The inspection opening shown below is necessary to clean the heat exchange element and the filter as
required. If not cleaned, they are likely to get clogged, resulting in degradation of performance.
• Use forklift to carry in the Air to Air Heat Exchanger units and use winch or hoist at installation of them.
