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.
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
Failure to comply to the above instructions may result
in equipment malfunction and will void warranty.
NOTICE
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.

8.2 PIPING AND VALVES

Install piping, fittings and accessories as required for specific
site conditions and requirements. Figure 3 indicates a typical
piping 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 1000 through 1600 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.
