SECTION 12
VENTILATION FILTERS (ELECTRICAL ENCLOSURE)
Ventilation Filters
- The electronics housed in the standard IP54 enclosure box are ventilated by a
combination of an intake air filter and pressurized air provided by the heat exchanger cooling fans.
Filter Inspection -
In order to ensure the electronics operate at peak efficiency and free from
troublesome temperature-related stoppages, it is imperative that the filter elements be kept clean:
1. Be sure the unit is completely off and oil reservoir is depressurized.
2. Disconnect, lockout and tagout power supply to the compressor package.
3. To service intake-side filter, open access door to the control panel – Refer to Figure 4-1, page 27, for
details. The discharge-side filter is accessible from the exterior roof panel.
4. Remove filter element (2) from each bracket by prying open the retaining grill area (1).
5. Inspect the elements. If dirty, gently clean with soapy water and allow to dry completely before re-
installation. If damage is evident, replace.
6. Replace elements into frame and replace snap grills.
7. Replace access panel in reverse order.
8. Close access doors.
