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 dryers 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.
