Chapter 4: Preventive Maintenance
Important. The AIRSYS WPUs are designed to be among the highest performing in the world for both
energy efficiency and reliability. Good preventive maintenance (PM) techniques are a crucial part of maintaining
that high level of energy efficiency and reliability. It is also important to keep track of findings during each PM
event so that trends can be established for future reference.
Preventive Maintenance Schedule
This section provides guidelines for the owner of an AIRSYS unit to ensure that the equipment continues to perform
well. Following these guidelines for regular care will help avoid serious damage to components and expensive
repairs by skilled personnel.
Table 30: Preventive Maintenance Schedule
Inspect all wiring for signs of wear
Based on local conditions
More frequently in areas with active rodent
or insect populations that can damage wiring
Inspect all hardware for “snug” connection
Make note of any loose hardware so it can
be checked again at next scheduled PM
Air filter inspection/cleaning and
replacement if needed
Based on local conditions
Depends on the amount and frequency of
airborne particulates in the area
Inspect and clean condenser coil
More frequently in areas that experience
excessive airborne particulates that will
collect on the condenser coil
Physical Inspection of Air Damper
Danger. Stop the machine and remove the power supply from the equipment before performing maintenance
operations.
Important. All PM should be performed by an AIRSYS Authorized Service Technician (AAST) to ensure
the manufacturer’s warranty is preserved.
General Operation Check
It is a good idea to compare the operation of the equipment with the results of the previous inspection. Any
differences in operating characteristics can then be easily identified.
A detailed and periodic visual inspection of the equipment and a general cleaning are both important to ensure good
operation. Before beginning the PM steps, you should verify the general system status by looking at the areas
outlined in this section.
