9.0 SCHEDULED MAINTENANCE
9.1 INTRODUCTION
Ingersoll Rand Nirvana Cycling dryers require little maintenance. These
dryers utilize hermetically sealed compressors which do not require any
lubrication. Ingersoll Rand recommends component inspection and
service at regular intervals to obtain maximum performance from your
dryer.
9.2 REFRIGERANT CONDENSER
For proper operation, it is imperative that condenser fins be inspected
and cleaned on a regular basis. For applications where excessive dirt,
dust or debris is encountered, more frequent inspection and cleaning
may be required. An optional ambient air filter kit can be easily installed
outside the condenser.
9.3 CONDENSATE DISCHARGE SYSTEM
On a minimum of a monthly basis, the operation of the drain should be
checked. Periodically, the drain should be removed and cleaned to
ensure no debris from the system is trapped inside. Ingersoll Rand
Nirvana Cycling dryers are equipped with a drain isolation valve,
enabling the valves to be cleaned during dryer operation after the drain
isolation valve has been manually closed. The drain isolation valve
requires a quarter turn to isolate the drain from system pressure.

WARNING
If your dryer is installed without a drain isolation valves (filter stop),
failure to depressurize the dryer may result in serious injury. Do not
remove the drain valve without depressurizing the unit.
