9.0 SCHEDULED MAINTENANCE
9.1 INTRODUCTION
Ingersoll Rand
Nirvana™ Cycling refrigerated air dryers require
little maintenance. These dryers utilize hermetically sealed
compressors which do not require any lubrication. Fan motors
require lubrication at both oil ports every six months.
Ingersoll
Rand
recommends component inspection and service at
regular intervals to obtain maximum performance from your
dryer.
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.
9.3 CONDENSATE DISCHARGE SYSTEM
9.3.1 SOLENOID DRAIN (STANDARD)
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
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 valve is located near the solenoid valve and
requires a quarter turn to isolate the drain from system
pressure.
9.3.1.1 CLEANING INSTRUCTIONS-SOLENOID DRAIN
Be sure dryer is depressurized or isolation valve is
closed.
Disconnect drain body from filter stop.
Loosen connector screw to allow the electrical
connector assembly to be removed from the D.I.N.
unit solenoid.
Remove retainer nut and separate the valve body
from the D.I.N. unit solenoid. Unthread the plunger
tube assembly in a counterclockwise direction until
plunger separates from valve body.
Clean beveled washer, thread gasket, spring
assembly and strainer with soap and water. Do NOT
use solvents of any kind, as failure to the seals will
occur. Be especially careful to clean the center brass
orifice and the rubber gasket orifice on the orifice
cup with a straight pin.
Reassemble all drain components after the drain has
been cleaned and inspected. Reposition the orifice
hole on the rubber gasket of the orifice cup in the
line and closest to the arrow indicated on the valve
body.
Reassemble valve and install in reverse order as
described above.

8.0 INSTALLATION AND INITIAL START-UP
the alarm will reset and the LCD panel will return to its default
display. After the refrigeration system shuts off, air flow may be
slowly introduced to the dryer.
NOTICE
If power is removed from the dryer for less than
two hours, the crackcase heater delay will be
automatically bypassed. If, however, the power is
removed from the dryer for more than two hours, the
full crankcase heater delay must be observed.
