9.2 REFRIGERANT CONDENSER
For standard dryers, regular inspection and cleaning of the condenser
is recommended. Ingersoll Rand dryers may be equipped with an
optional ambient air filter designed to protect the condenser from dirt
and debris that can accumulate on the condenser. For proper operation
with this option, it is imperative that this filter be inspected and cleaned
on a regular basis. Annual replacement of the filter is recommended.
For applications where excessive dirt, dust or debris is encountered,
more frequent inspection and cleaning may be required.
Before drain maintenance work always close the drain isolation
ball valve and ensure that the device is:
• pressureless and
• de-energized.
