General Maintenance
1. Inlet and approaches to DX module and compressor unit should be kept clean and free from any
obstruction.
2. All fasteners should be checked for tightness each time maintenance checks are preformed prior
to restarting unit.
3. DX coil modules require little attention when moving clean air. Occasionally, dust may
accumulate on the coil causing low airflow or reduced cooling. The DX coil should be inspected
and cleaned every 6 months during the cooling season.
Every 6 months
1. Check and clean the drainage pan and drain.
2. Clean the DX coil from the entering air side. This will keep any grit or particulate from lodging it’s
self deeper into the coil. The air deflection screen must be removed before cleaning.
Yearly
1. Check the coil for damage. If there is evidence of a leak, seek professional help.
2. Check the moisture indicator inside the sight glass. If the indicator reads wet, call a professional
for more information and repair.
