Chapter 4: Maintenance
WARNING
All maintenance shall be performed by qualified persons. Always disconnect the
power, communication and alarm output cables from the heat exchanger before
any maintenance and do not reconnect them until the maintenance is completed.
To maintain full performance of a heat exchanger operating in a harsh environment,
preventative maintenance should performed every six months.
Note:
Make sure all the power input is shutoff before any maintenance work is done.
Tool lists:
1. Air compressor or a dedicated clean water gun
2. Brush

4.1 Filter
This heat exchanger has no filters; the cabinet provides air filtration. Any debris
blocking the openings will reduce air into the heat exchanger, thereby reducing its
performance.
