Inspect and Clean Condenser Coils
During times of peak usage, the condensing coils must be able to offer maximum thermal exchange.
Debris such as paper, dead leaves, and dust can be sucked in around the coils, reducing the thermal exchange rate.
Remove any objects from the coil which may have accumulated and wash the system with water and commercial
coil cleaner.
Dirty condenser coils may trigger the high pressure switch and cause system lockout.
You should check the coil condition more frequently if your environment experiences seasons of high dust or falling
leaves.
Inspect and Clean the Drain Pipe
To avoid water overflow, ensure that the system has proper drainage for condensation discharges. The pipe and
outflow should be completely free of any obstructions. If necessary, clean the drain and outflow area.
Physical Inspection of the Damper
The air damper is a critical element in the WPU. If it does not function normally, the free cooling function will fail.
This can be avoided by periodically and regularly checking the following:
1. Check if the damper can fully open and close via the manual override
2. Check if the nuts are properly tightened, as shown in the following images.
