Auto Restart

Should the dryer lose power while in the "On" mode, the dryer
will revert to the "On" mode once power is restored. Similarly,
should power be removed from the dryer while the dryer is in
the "Off" mode, the dryer will remain in the "Off" mode once
power is restored until the On/Off switch is depressed or the
remote switch is closed.
8.1

LOCATION AND MOUNTING

The dryer should not be located in an area where ambient temperature
is likely to exceed 113°F (45°C) or be less than 50°F (10°C). The dryer
must be located in an area that provides sufficient clearance from walls
and other adjoining equipment to allow easy access for servicing and
maintenance requirements. A minimum of 18 inches is required to allow
free flow of air to the condenser inlet.
On installations with a relatively steady flow rate, the dryer is normally
connected after the air receiver. If loads fluctuate widely, the dryer
should be positioned ahead of the receiver and sufficient storage
capacity downstream is necessary to prevent excessive air flow through
the dryer.
When installed after any compressor that causes significant vibration or
air pulsation, such as reciprocating compressors, proper vibration
isolation and pulsation dampening devices should be added to protect
the dryer.
NOTICE
a
Failure to comply to the above instructions may result in equipment
malfunction and will void warranty.
NOTICE
a
Always use a backup wrench when making any threaded connection
to the dryer. Failure to use a backup wrench may result in damaged
tubing and components internal to the cabinet.

arrangement for a refrigerated dryer, including dryer and filter bypasses.
This figure can be used as a guide for valve and accessory placement
in the system.
Ingersoll Rand NVC200-400 models come factory installed with a drain
isolation valve (D). The isolation valve permits maintenance of the
automatic drain without isolating air flow to the dryer. To operate dryer,
all valves shown in Figure 3 are to be closed except valves (B), (C) and
(D). Valve (A) is used for bypass purposes and valve (E) is for test and
manual drain purposes.
8.3

FILTRATION

To protect the air dryer from gross contamination associated with
compressor oil and debris and ensure maximum dryer performance, a
pre-filter is recommended. Pre-filters and post-filters sized to your drying
application can be provided by Ingersoll Rand and are available factory
installed. Call your local distributor to select the filter that best suits your
filtration requirements. In addition to air filtration, condensate discharge
oil/water separators are also available to address stringent EPA
regulations.
