8.1.4 Air Handling Units (Air Conditioner, Heat Exchanger, etc.)
Recommended Schedule: Every 2 months (sooner if external environment is harsh; IE: machining
area with coolant mist in air).
Equipment supporting the Micro NR system environment must be sufficiently maintained. Internal
electrical enclosure (which the MNR Units are housed) heat load can be calculated using the
internal power consumption data in table 2.3. Verify support equipment meets the following
requirements, as applicable to the unit type:
1. The unit is free from dust, oil and foreign matter.
2. All filtration devices are clean and air flow is not impeded.
3. The unit is securely and correctly mounted.
