Maintenance
Introduction
This chapter provides periodic maintenance and removal and replacement procedures for the OS-1933-E0-
003 Outdoor MCPA System.
Periodic Maintenance
Suggested periodic maintenance requirements are listed in Table 4-1.
WARNING: Wear proper eye protection to avoid eye injury when using compressed air.
CAUTION: Use only dry compressed air when cleaning the OS, do not use pressure washers.
To ensure proper cooling and prevent MCPA over temperature shutdown, one of the two booster doors
must be closed and secure at all times.
NOTE: Do not break the seals on equipment under warranty or the warranty will be null and void. Do not
return equipment for warranty or repair service until proper shipping instructions are received from the fac-
tory.
Cleaning Air Inlets/Outlets/Filter
The air inlets and outlets should be cleaned during periodic site maintenance. If the equipment is operated in a
heavy industrial or severe dust environment, the inlets and outlets should be cleaned as necessary. Cooling
efficiency can be reduced if dust and dirt are allowed to accumulate. Remove the panel and, using either
compressed air or a brush with soft bristles, loosen and remove accumulated dust and dirt from the air inlet
and outlet panels. Replace the panel when cleaned.
The air filters, located in the front and rear panels, also must be removed and cleaned using compressed air.
Refer to Air Filter Cleaning, page 4-10,Table 4-9, Figure 4-6 for filter cleaning and replacement instructions.
