Preventative Maintenance
Table 6-1 provides PM guidelines that should be followed for optimal performance. Following these guidelines
will help avoid serious damage to components and expensive repairs by skilled personnel.
Table 6-1 Preventative 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
Based on local conditions
More frequently in areas that
experience excessive airborne
particulates that will collect on the
condenser coil
Inspect drain pipes (condenser
and evaporator)
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 that the manufacturer’s warranty is preserved.
6.1 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, the general system status should be verified by looking at the
areas outlined in this section.
6.1.1 Check Main Voltage
Check that:
• The main voltage is within ±15% of the rated voltage required by the machine.
• The DC voltage is in normal range, if applicable. (36 -57VDC)
• The main electrical supply cable and the terminals, including the user terminal cable, are correctly
connected.
• All cables are secured to the system.
