•
The equipment room should be at least 3.7 km away from the sea or salt lake.
Otherwise, the equipment room must be sealed, with air conditioner installed for
temperature control. Saline soil cannot be used for construction. Otherwise, you should
select devices with advanced protection against severe environment.
•
Do not build the equipment room in the proximity of livestock farms. Otherwise, the
machine room should be located on the windward side of the pollution source
perennially. The previous livestock house or fertilizer warehouse cannot be used as the
machine room.
•
The machine room should be firm enough to withstand severe weather conditions such
as windstorm and heavy rain as well as away from dust. If the dust is unavoidable, keep
the door and window away from the pollution source.
•
Otherwise, the machine room should meet the construction standard in terms of noise.
•
Make sure the air vent of the machine room is away from the sewage pipe, septic tank,
and sewage treatment tank. Keep the machine room under positive pressure to prevent
corrosive gas from entering the machine room to corrode components and circuit
boards.
•
Keep the machine room away from industrial boiler and heating boiler.
•
The machine room should be on the second floor. Otherwise, the machine room floor
should be 600 mm (23.62 in.) higher than the highest flood level ever recorded.
•
Make sure there are no cracks or holes in the wall and floor. If there are cable entries in
the wall or window, take proper sealing measures. Ensure that the wall is flat, wear-
resistant, and dust-free, which should be up to the standard for flame retarding,
soundproofing, heat absorption, dust reduction, and electromagnetic shielding.
•
Keep the door and the window closed to make the machine room sealed.
•
The steel door is recommended for soundproofing.
•
Sulfur-containing materials are forbidden.
•
Keep the air conditioner from blowing wind straight toward the device or blowing water
drops from the window or air vent toward the device.
